NAVIGATIONAL DEVICES AND METHODS

FIELD OF THE INVENTION

The present invention relates generally to portable navigation devices and methods, and more specifically to wearable devices for navigation.

BACKGROUND OF THE INVENTION

At present, extreme, sports and military navigation are practiced either by memorizing a route on a map, by holding and reading a physical map, or by following visual and/or sound directions of a given navigation computerized application. These available practices are not practical for certain types of extreme, sport and military navigation scenarios and conditions. Often, they are ineffective in directing the user to his target accurately, on time and safely.

Most prior art systems relay and employ subjective skills such as cognitive abilities (e.g. intelligence, perception of space, natural orienteering, etc.) and weak, easy to disrupted, senses such as vision and sound: The resulting navigation experience of prior art devices is that they are demanding and often fail due to environmental disturbances to the user.

The prior art technique of memorizing a route on a map is a practice which requires subjective orientation skills, intensive learning and training and considerable preparation time before the navigation. Moreover, while navigating on an unmarked route at natural/wild/hostile environments, it becomes a difficult task even for professionals. Mistakes and misdirection are common, obliging the hiker, athlete or soldier to stop and open an actual map (or a computerized navigation application). This costs them time, disqualification in competitions and military courses, their professional reputation, and may even create grave danger at hostile military scenarios while stopping and illuminating the map.

Holding and reading a physical map is a practice which is impractical for sport, extreme and military navigation scenarios and conditions, as it requires the hiker, athlete or soldier to continuously stop and open an actual map and thus costing them time, disqualification in competitions and military courses, their professional reputation, and may cause grave danger at hostile military scenarios while stopping and illuminating the map.

Visual directions -as in holding and reading a physical map, this practice is irrelevant for sport, extreme and military navigation scenarios and conditions as it requires the hiker, athlete or soldier to continuously stop and look at the actual map and thus costing them time, disqualification in competitions and/or military courses, their professional reputation, and may create grave danger at hostile military scenarios while stopping and using an illuminated screen.

There are also several wearable devices offering visual based indications for navigation (alongside vibration based indications). These applications hold the same described limitations and are even less practical as they employ tiny wrist-fitted screen, obliging the hiker, athlete or soldier to watch and focus on tiny visual indications while they are at a hectic environment requiring their optimal attention.

Verbal sound directions - this practice is irrelevant or less practical for sport, extreme and military navigation scenarios and conditions as it requires the hiker, athlete or soldier to focus on listening to the instructions while they are at a noise- hectic environment and need to be listening to their sound-rich environment, such as radio communication, conversations, potential threats, targets, animals in hunting, the weather, and even music, in the case of some athletes.

Vibration directions - there are several wearable devices offering vibration- based navigation. These ones namely offer a wristband comprising a plurality of haptic feedback devices arranged around a circumference of the wristband. This practice is irrelevant or less practical for sport, extreme and military navigation scenarios and conditions as the vibrating directions are of plurality of complex sensations imposed on one narrow area surrounding one hand and thus it requires the hiker, athlete or soldier to be extremely focused on (and attentive for) various complex sensations pulsing on a narrow segment of one of their hands: All that, while they are practically overwhelmed by stimulations from all senses all over their body (E.g. noises, rain, beatings, wounds, cold, heat, etc.) and by high-adrenaline sensations and emotions (fear, pain, aggressiveness, etc.). In other words, in the intense context of real life the hiker, athlete or soldier act in, they practically cannot differentiate between the concentrated vibrations and thus to translate the vibrations to actual directions; as the vibrations are limited to a too narrow area on the wrist.

WO 2014099004 A 1 describes an apparatus, method and other techniques for a wearable navigation device. For example, an apparatus may comprise a wristband comprising a plurality of haptic feedback devices arranged around a circumference of the wristband and logic to wirelessly receive navigation information from a computing device and to output the navigation information using one or more of the plurality of haptic feedback devices, the output comprising a mechanical representation of the navigation information. Other embodiments are described and claimed.

There is therefore an unmet need of a device capable of providing unmistakable, distinguished directional commands, without the need for verbal and/or visual instructions.

The device may be constructed and configured to provide at least one tactile stimulus to an arm 110 of the user. The tactile stimuli may be selected from vibrations, electrical pulses, electrical shocks, movement of a surface against the skin of the arm and combinations thereof.

Many different types of devices are envisaged, as are exemplified herein. Typically, data is transmitted to and from the laptop/tablet/smartphone via a public network 130. Mobile device 120 is operative to transfer data directly to and from device 110.

The device is also termed herein a "forearm-band sensation device". It is specifically designed and developed to deal with the extreme circumstances and conditions the user is experiencing at sport, extreme and military navigation scenarios and conditions.

The forearm-band sensation device is specifically designed and developed to enable intuitive navigation by the user despite the extreme circumstances and conditions the user is experiencing at sport, extreme and military navigation scenarios and conditions.

The forearm-band sensation device is specifically designed and developed to enable intuitive navigation by the user while overwhelmed by stimulations from all senses all over the body, such as noises, rain, beatings, wounds, cold, heat and the like and by high-adrenaline sensations and emotions such as fear, pain and aggressiveness.

The invented forearm-band sensation device is specifically designed and developed to separate, distinguish and differentiate between the sensations (vibration and/or flicker or other tactile stimuli as detailed hereinabove) and thus enabling the user to easily comprehend the directions and thus to intuitively navigate at sport, extreme and military scenarios and conditions.

Reference is now made to Fig. 2A, which is a simplified schematic illustration of an upper view 200 of a tactile instructions device 110 of system 100 of Fig. 1, in accordance with an embodiment of the present invention. The device is adapted for placing on a forearm of a user. When the user is human, the devices dimensions are typically 10-40 cm in length, 5-20 cm in width, and has a thickness of 0.1-80 mm. The device may be made, in part out of a flexible polymer, such as rubber, silicone, plastic, a textile, a fabric and combinations thereof. When the device is for an animal, the dimensions are adjusted to match a body or leg of the animal. For example, for a dog- see Fig. 14 hereinbelow.

Turning to Fig. 2B, there can be seen a simplified schematic illustration of a lower view 250 of a tactile instructions device 110 of Fig. 2A, in accordance with an embodiment of the present invention.

Fig. 10B shows a lower view 1020 of tactile instructions device 1000 of Fig. 10A, in accordance with an embodiment of the present invention. The device may comprise a peripheral strengthening band 1024 and tactile elements (not shown) disposed on some/all of the arms. The tactile elements may be vibrators and/or other suitable stimulating elements. The device further comprises a Micro USB socket 1026, used for charging and for receiving and sending data (while on wired configuration with the Smartphone et.al devices).

Fig. IOC is a simplified schematic illustration of a side view 1050 of tactile instructions device 1000 of Fig. 10A, in accordance with an embodiment of the present invention. The device may have dimensions of 14 cm in width, adjustable 10- 50 cm in length, using a strap, like a watch strap, buttons, studs, Velcro or any other suitable fastening means (not shown). The thickness of the device may be 1.3 cm.

Reference is now made to Figs. 11A and 11B, which show a simplified schematic illustration of flowchart of a method 1100 for tactile navigation instruction, in accordance with an embodiment of the present invention.

The user/team leader launches a navigation application in the smart phone 120, in a launching application step 1102.

He/she checks to see if there is an available "saved and complete" trek (route) in checking step 1104. If yes, he proceeds to step 1106, if no, he has the options to proceed to edit a saved Trek route in an editing trek step 1108. He edits a saved trek (route) by either moving/deleting waypoint on map or by the editing tools in application's menu. He may optionally rename and/or delete the trek.

In a saving trek step 1110, he saves the edited trek on the smartphone's application.

Another optional step is to create a trek using a Google-generated map, waypoints and route ("search box") in a trek creating step 1112.

Another optional step is to create a new trek by "drawing trek step 1114" (route) by either (1) touching the map to set waypoints and/or (2) assigning coordinates

Another optional step is an import a trek step 1116 by importing one or more of a map, waypoints and one or more route from external resources via the internet on smartphone or via a removable SD card 120.

After steps 1112, 1114 or 1116, the user saves the trek in another saving trek step 1118.

Thus, he can now choose and "load trek" in a choosing and loading trek step

1106.

The user may be alone, with a dog, or with a team/group. He therefore has to choose the appropriate configuration for setting up the trek.

He opens a paring page in the application to define the number and type of trek participants in a "choosing one or many step" 1120 (choose one device to pair (1 : 1) or one to many (1 :M)?). Accordingly, he must choose how many devices need to be paired. If there is a group of trek participants, he asks the group members to switch on their portable/wearable devices 110, 700, 910 in an activating devices step 1122. Thereafter, he proceeds with the method of Figs. 12A and 12B, described hereinbelow.

If the user is to use a wearable device for the trek, or for example a dog 1402 is to wear a device 1400, then the user activates the device in step 1126 and pairs it with his device via the application in smartphone 120 (Fig. 1). If there is no wearable device to pair, then he proceeds to a starting trek step 1134. He then navigates "traditionally" per the application's visual and/or sound directions in a traditional navigating step 1136.

If there is a paired device, then he puts a device 1400 on his forearm (or on the dog's back (Fig. 14)) in a putting on step 1128.

He then clicks "start trek" on device 1400 or portable devices 110, 700, 910. He navigates by sensations per invention's navigational methodology, its direction's touch language and by its intuitive UX in a navigating step 1132.

In an activating step 1140, he then click "start trek" on the cellphone or wearable device. The wearable device begins to provide tactile instructions to the. user, man or dog, that moves, in accordance to the wearable device's directional instructions towards the Start point (First waypoint). Once reaching the first waypoint, the user receives a notification alert in an alerting step 1142;"you have reached the start point (first waypoint)" by means of two calibration cycles and activation of the appropriate directional arm (vibrator and/or LEDs) to direct the user to right path to head towards a second waypoint.

The user (and optionally a dog) move towards the second waypoint. He then receives directional alerts in a second alerting step 1144. For example, before a new waypoint, the portable device emits four short bursts (light and vibration) in another attention alerting step 1154- 4 bursts in one and a half (1.5) seconds, on an appropriate directional arm of the device- indicating the correct path and direction towards the next imminent waypoint.

When the user diverts from his route/azimuth, he receives a correction alert in a correcting step 1146. For example, the portable device emits four short bursts (light and vibration) for one and a half (1.5) seconds, on the relevant directional arm of the device, indicating the required correction angle.

If, for example the diversion is extreme (10-15 meters diversion), a STOP alert is triggered: One long burst (1 second) - All vibrators together (the system's STOP alert) and a STOP sign on the device screen, followed by a correction alert on the relevant arm of the wearable device indicates the correction azimuth/direction to be followed immediately by the user.

When the user actually reaches the correct waypoint, he/she receives a "turn now" instruction in instructing step 1150. For example, the wearable device provides a "TURN NOW" alert of two long bursts (light and vibration) - one (1) second each, to indicate the path/angle of movement towards the next waypoint in the trek.

Moreover, further alerts are provided in alerting step 1156, when moving at up to 6 Kph (walking) - 10 meters before the next notification alert, alerting step 1158, At 7-12 Kph (run) - 20 meters before the next turn, and at 13 < X Kph (cycling, driving) - 30 meters before the next turn, alerting step 1160.

When reaching a final destination a notification alert step 1152 indicates that the user has reached an end point (last waypoint). For example, two STOP orders, one calibration cycle and a STOP sign on the device's screen.

Throughout the trek, the available directions/azimuths are identified by light and vibration on the relevant arm of the wearable device, by the user in alerting steps 1148. These include Forward (FW); Backward (BW); 45° right; 90° right; 45° left; 90° left; "half turns" between the basic arms (The 22.5° directions/azimuths).

Reference is now made to Figs. 12A and 12B, which show a simplified schematic illustration of flowchart of a method 1200 for group tactile navigation instruction by a team leader, in accordance with an embodiment of the present invention.

In an opening pairing page step 1202, the leader/user opens a paring page on application on smartphone 120 and he/she chooses the "One to many (1 :M) configuration" .

Thereafter, all members in the group switch on their portable/wearable devices 110, 700, or 910 in an activating step 1204.

These devices will be listed on a pairing page of the application on Smartphone 120, in a listing step 1206.

In a checking step 1208, the devices listed in step 1206 and recognized, are checked to see if they have been used as paired before.

If yes, the user can now choose the devices to pair to; a) one by one, b) pair all or c) pair a selected few, in a choosing pairing technique step 1222.

Once paired, the user may name the paired device with an understandable name (e.g. number or name of the user who is to wear the device) in a naming step 1212.

Once paired, the named devices appear on the app in an uploading device name step 1224, either on a map page (Fig. 15B) and/or on the Menu (Fig. 15A): The leader's icon 1554 looks a bit different than the other group members' icons 1552. Once paired, the devices may be (per device) set to receive directional alerts (as of the leader) or only to alert of separation/split (step 1226).

The leader may wear the device on his forearm, the users may put on their devices and/or a device may be put on dog's back in a wearing step 1228.

The group is now ready to go and the leader click a "Start Trek" button on his device in a starting trek step 1230.

In a testing device step 1232, it is checked to see if all devices are set to receive directional alerts. If yes, all group members navigates together as one by sensations per invention's navigational methodology, its direction's touch language and by its intuitive UX, in a directing step 1236.

If no, group members are led by team leader who navigates by sensations per invention's navigational methodology, its direction's touch language and by its intuitive UX, in a leading step 1234.

Thereafter, it often occurs that team member(s) are out of (pre-set) range of communication (Bluetooth, Low Energy Bluetooth, RF, WiFi other), thus are separated detached from the group, in a "lose part of the group step" 1238.

In a stopping step, 1240, the leader and the detached user(s) both get a "Stop" alert (all vibrators at once) twice on their portable devices, AND the icon(s) of the separated user(s) turns red on the Application map screen and Menu on smartphone 120 (Fig. 1).

The leader tries to regroup by trying to minimize the distance from the detached user(s) and/or in an attempting to regroup step 1242 by clicking on the red icon(s) of the separated user(s) on the application. This allows the leader to; (1) Know who is the separated user (their assigned name or number) (2) Connect - Try to manually reconnect with the user's device if the auto connections fails (3) Forget - Un-pair the device and the application (4) Rename - When/if the device will be used by a different person (5) Delete - The device will be deleted from the App's logs (will require a new pairing process if tries to re-pair). It is relevant too, when a device has a fatal technical issue.

In a regrouping step 1244, when the team regroups, the detached user will receive a "Calibration" alert and the Leader will receive a "Calibration" (full cycle of vibrations) AND a directional alert to indicate and lead the Leader to the next waypoint.

Thereafter, in a continuing the trek step 1246, the group continues the navigation.

Reference is now made to Fig. 13 A- 13E, which are simplified screen shots 1300, 1310, 1320, 1350, and 1370 on touch-screen 202 of the tactile instructions device 700 of the system of Fig. 1, in accordance with some embodiments of the present invention.

Screenshot 1300- Start your trek-opening screen. After pairing the application on the mobile communication device 120 (Fig. 1) and the tactile instructions device 700, clicking "Start your trek" will begin the navigation via device 700. Typically it will show a text 1304, a picture or image 1302 and an on/off button 1306. The embedded application then leads to a second screen 1310 "the environment".

Environment-second screen 1310: Presents a compass (center arrow) 1318, a time of day ("Time") 1320, an ambient temperature ("Temp.") 1312 or other temperature 1314, an elevation (shows the degree of elevation 1322- up or down shown by an arrow- of current location versus a next waypoint, an altitude 1316 above sea level.

This leads to a third screen 1320 - a navigation screen, which presents a bearing in degrees 1338, a speed of the user 1322, a current longitude 1336, a current latitude 1334, Play/Pause 1332 and stop of the navigation, enabling the user to set a new waypoint (on the go) by clicking the set landmark button 1330. The new Waypoint will be added to the Trek and the system will lead the user from the newly created Waypoint to the next one.

This leads to a fourth screen 1350 Trek's Distance, which presents a current distance from a start point 1356, a current distance from a last way point 1352, a current distance to the next waypoint 1358 and a remaining distance to a destination (final waypoint) 1354.

This leads to a fifth screen 1370 (Trek's Time) and presents a running time from a start point 1376, a running time from a last waypoint 1372, a remaining time, per average speed of the user to a next waypoint 1378 and a remaining time to a final destination 1374.

Reference is now made to Fig. 14, which is a simplified schematic illustration of a tactile instructions device 1400 on a dog 1402, in accordance with an embodiment of the present invention. The device comprises a number of straps 1412, 1416, attached to arms 1410 of the device, for attaching it to the dog's body.

Dog handling and direction-

Visually-impaired user support - The current practice of a guide dog supporting a visually impaired person is primarily of helping the person to avoid obstacles. With a device of the present invention placed on the dog's back, and with basic training, the dog may now lead the visually impaired person to its destination and thus to become a complete solution of both leading and guiding.

Police, rescue and military support dog - the current practice of a sending a dog to a remote task is by either walking next to it or by placing a camera and speaker from which the handler is commanding the dog: Walking next to it - places the human handler in harm's way and thus undermine the reason for the usage of police/military dogs. The prior art practice of placing a camera and speaker on a dog is as with human navigators. The practice employs sound directions, on which the dog should rely. These employ the weak, easily disrupted, senses, such as vision and sound. These result in a navigation experience that is demanding and subjected to environmental disturbances. With a device of the present invention device placed on the dog's back, and with basic training, the dog may now be directed to the destination without a human escort or by the easy to be disrupted sound directions.

Memory-disabled user support (e.g. Alzheimer's disease) -weary or memory- disabled people may be supported by the device of the present invention. There is no need to remember the way home. Simply wear it on the forearm and be led home.

In summary, the devices of the present invention are constructed and configured to provide a user with:

a) distraction-free navigation - no need to stop and open a map; no need to be focused on complex signals on a limited body area (e.g. wrist);

b) night-time navigation - by eliminating the need to stop and open an illuminated map;

c) sensation-based directions only - the device of the present invention uses the sensation of touch to guide and direct. It is a much more deep and basic sense and less subjected sense than the senses of vision and sound. And thus, when under external stimulations, pressure, harsh field conditions, the elements, etc., a user of the device of the present invention can comprehend the instructions (in contrast to the users of traditional navigation tools, which tend to fail; the devices provide intuitive navigation - by a simplified wearable directions' system, method and methodology;

Limited sensation types - Only vibrations and/or flickers (no sound or graphics)

Sufficient physical distance between the sensation generators (E.g. micro-vibrators and LED emitters) for distinguishing the directions.

Less time needed to memorize the route— The practical nature of the invention reduces the need to memorize the map or even to look at the map before the navigation

Like no other, the devices of the present invention are Forearm- mounted - leaving ones hands totally free for the task. Multi-sensory - it economically vibrates and flashes to guide you; Simple— it has everything you need and nothing you don't; Shockproof & water- resistant - it's designed and built to withstand harsh environments; Intuitive design - easy to understand and operate; Safe, distraction- free navigation - no need to stop and look at a map or focus on complex signals; Covert nizht-time navigation - disable the flicker indications to remain night-covert; Lons battery life - 20 hours' in normal usage and rechargeable.

The device of the present invention holds innovations in the domains of Operational Design, User Experience (UX) practicality and Navigation Methodology:

Its revolutionary 6 directional arms' operational layout is geared to achieve optimal distance between the sensations, enabling the user to easily differentiate between the physical directions' instructions. And, to provide 360° bearing coverage. There are micro-vibrators placed on the tip of each directional arm and the vibrations are ergonomically tunneled to a specific point on the users forearm; resulting in a feel akin to being poked in the skin, as someone is physically pointing and leading you.

This extraordinary layout creates a natural, intuitive User experience (UX) as the user can immediately use it without studying or training. During extensive testing, the users' comprehension was found to be immediate.

1) The revolutionary design and intuitive UX combination yields an efficient, practical navigation Methodology by which, and based on the speed of the user, the device of the present invention will physically indicate and alert the user before a required turn on where to head on.

The present invention provides systems 100, 900 and methods 1100, 1200 for intuitive navigation at sport, extreme and military scenarios and conditions.

The present invention relates generally to wearable navigation devices 110, 300 and methods, and more specifically to methods and systems for wearable navigation forearm-band for intuitive navigation at sport, extreme and military navigation scenarios and conditions.

The present invention is a wearable navigation forearm-band that guides & leads the user (or a group of users) such as a hiker, hunter, athlete or soldier to his/hers destination without distractions and with optimal considerations to the extreme circumstances and conditions the user is experiencing.

Directions Methodology— A new language

Notification alerts;

- Reached Start point (first waypoint) - Two calibration cycles and the relevant directional arm to direct the right path to head towards the 2nd waypoint.

- Reached End point (last waypoint) - Two STOP orders, one calibration cycle and a STOP sign on the device's screen.

Based on the speed of the user, the device alerts the user in advance and before a required turn. Here's how:

Attention alert:

- Before a waypoint, 4 short bursts (light and vibration) - 4 bursts in one and a half (1.5) seconds, on the relevant directional arm: Indicates the correct path towards the imminent waypoint. In up to 6 Kph (walk) - 10 meters before the next turn;

7-12 Kph (run) - 20 meters before the next turn; and

13 < X Kph (cycling) - 30 meters before the next turn.

Turn alert;

- When reaching the actual waypoint, there is a TURN NOW alert of two long bursts (light and vibration) - one (1) second each. To indicate the path towards the next waypoint.

Correction alerts;

- When the user diverse from route/azimuth - 4 short bursts (light and vibration) for one and a half (1.5) seconds, on the relevant directional arm- indicating the required correction angle.

If the diversion is extreme (10-15 meters diversion), a STOP alert is triggered: One long burst (1 second) - All vibrators together (the system's STOP alert) and a STOP sign on the device screen. Additionally, the relevant arm will indicate the correction azimuth/direction.

The five basic directions/azimuths; identified by light and vibration on the relevant arm. As exemplified in Figs. 6 and 7. If the user needs to turn right 45 degrees, vibrator 604 vibrates. If the user needs to move 90 degrees to the right, vibrator 606 vibrates. If the model device is 300 (Fig. 3B) having lights and vibrators, then the appropriate lights and/or vibrators are activated to provide a command.

If the user wears device 910 (Fig 9), then, for example to move 22.5 degrees to the right, arms 906 and 904 will vibrate alternatively. All devices of the present invention are constructed and configured to provide the following commands to the user by tactile and/or light instructions:- forward (FW), backward (BW), 45 degrees right, 90 degrees right, 45 degrees left and 90 degrees left.

Commands to move at an angle between the above angles are provided by vibration/lighting of two adjacent arms, such as a 22.50° move command:

Attention alert; before a turn, two (2) short bursts (light and vibration) - four (4) bursts in total in 1.75 seconds, on the two relevant directional arms. For example, in a case where a 22.50 turn to the right is required, the FW arm and the 45° to the right arm will alternatively blink and vibrate.

Turn alert; TURN NOW - 2 long bursts (light and vibration) - 4 bursts in total in 3 seconds (0.75 each), on the two relevant directional arms. For example, in a case where a 22.5° turn to the right is required, the FW arm and the 45 degree to the right arm will alternatively blink and vibrate 2 times each.

BEST MODES OF IMPLEMENTATION-

The present invention provides systems and methods for intuitive navigation and thus is best implemented in the following examples of navigation modes:

Sport/Extreme navigation (Day/Night)

a. Sport navigation - The user is subjected to time constrains, harsh field conditions and the elements.

b. Hiking - The user is subjected to harsh field conditions and the elements and carries heavy equipment.

c. Hunting - The user is subjected to harsh field conditions and the elements, carries heavy equipment and needs to be attentive to the surroundings.

d. Wind surfing - The user is subjected to waters conditions, the elements (and sometimes time constrains), holding and steering the board and needs to be attentive to the surroundings e. Kayaking - The user is subjected to waters conditions, the elements (and sometimes time constrains), holding and steering the board and needs to be attentive to the surroundings.

f. On/Off-road Running - The user is subjected to time constrains, complex and/or harsh road/track conditions and the elements.

g. On/Off-road Cycling - The user is subjected to road/track conditions, the elements and time constrains, holding and steering the bicycle and needs to be attentive to the surroundings. h. Mountain climbing - The user is subjected to harsh field conditions and the elements, carries heavy equipment and needs to be attentive to the surroundings, i. Military navigation (Day/Night) - j. The user is subjected to harsh field conditions and the elements, carries heavy equipment , time constrains, needs to be attentive to the surroundings and to stealth requirements

k. Assisting visually-disabled/blind users 1. A visually disable or blind person may find the systems and devices of the present invention very useful in assisting him/her in getting around. The user is subjected to varied terrains and needs to be attentive to the surroundings.

m. Casual urban navigation

n. The user is in ant unknown area, maze-like streets, time constrains, usually is an inexperienced navigator,

o. The user is subjected to the elements, carries equipment, time constrains, needs to be attentive to the surroundings. p. Dog handling and direction

q. Visually-impaired user support - the current practice of a guide dog supporting a visually impaired person is primarily of helping the person to avoid obstacles. With a device of the present invention placed on the dog's back, and with basic training, the dog may now lead the visually impaired person to its destination and thus to become a complete solution of both leading and guiding.

r. Police, rescue and military support - the current practice of a sending a dog to a remote task is by either walking next to it or by placing a camera and speaker from which the handler is commanding the dog: Walking next to it - places the human handler in harm's way and thus undermine the reason for the usage of police/military dogs. The prior art practice of placing a camera and speaker on a dog is as with human navigators. The practice employs sound directions, on which the dog should rely. These employ weak, easily disrupted, senses, such as vision and sound. These result in a navigation experience that is demanding and subjected to environmental disturbances.

s. With a device of the present invention device placed on the dog's back, and with basic training, the dog may now be directed to the destination without a human escort or by the easy to be disrupted sound directions.

t. Memory-disabled user support (e.g. Alzheimer's Disease) u. Weary or memory-disabled people may be supported by the device of the present invention. There is no need to remember the way home. Simply wear it on the forearm and be led home.

The systems of the present invention overcome the prior art requirements for visual and auditory directions as well as the requirement to hold and read a physical map in practice. Moreover, using the systems of the present invention, there is no longer a need for sound directions. Thus the user, does not need to focus and listen to the instructions while at a noise-hectic environment (from radio communication, conversations, potential threats, targets, animals in hunting, the weather, and even music, in the case of some athletes).

The systems of the present invention overcome the prior art requirements for using the prior art navigation gadgets. There are few gadgets emerging offering vibration-based navigation. The more relevant ones are urban-fashion styled bracelets, offering a wristband comprising a plurality of feedback devices arranged around a circumference of the wristband and is positioned on a narrow area of the hand- the wrist. However, in the intense context of real life the hiker, athlete or soldier act in, they practically cannot differentiate between the concentrated vibrations and thus to translate the vibrations to actual directions; as the vibrations are limited to a too narrow area on the wrist.

In sharp contrast with the prior art devices, the devices and systems of the present invention guide and lead the user thereof, such as a hiker, hunter, athlete or soldier, sight-disabled person, to his/her destination without distractions, as well as with optimized considerations to the extreme circumstances and conditions the user is experiencing.

The forearm wearable navigation devices of the present invention, separate, distinguish, differentiate and simplify the navigation indications/instructions to the user and thus creating an intuitive navigation experience.

The devices of the present invention provide sensation-based directions. As illustrated herein, there are micro-vibrators placed on the tip of each directional arm. The vibrations are economically funneled to a specific point on the users forearm, resulting in a feel of a firm pointed touch on the skin, as if someone were poking the user's skin. The device also provides one or more visual indications, which can be disabled, by embedded LED emitters in each directional arm.

Materials of construction of the device- there are several cover ("shell") types. textile, silicone, rubber or a combination thereof. These provide the device with flexibility, durability, water resistance, light-weight and a slick look.

Team usages of the systems of the present invention (see Figs. 12). When a "split" occurs in a team of users, the leader and the detached/lost user will both get a "Stop" alert (all vibrators at once) twice (a unique alert to this scenario). When the team regroups, the detached user will receive a "Calibration" alert. The leader receives a "Calibration" (full cycle of vibrations) alert and a directional alert simultaneously, to indicate and lead the leader to the next waypoint.

Integration to external devices:- the unique vibrations' language, created by the systems of the present invention, enables creation of additional alerts to indicate of additional scenarios and necessities. For example, alerting on a too fast heart's pulse- rate will alert the user by a slow pace vibration, instructing him/her to slow down.
