Description:

INPUTTING INFORMATION WITH FINGER-MOUNTED SENSORS

BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates generally to inputting information, and more particularly to an input apparatus and method for inputting information into an electronic device.

2. Description of Related Art

Recent years have seen a dramatic increase in mobile computing. Devices such as cellular telephones, audio and video devices, and many other electronic devices have become increasingly complex, while at the same being miniaturised for mobile use. Miniaturisation causes a problem for information entry into the devices, since such devices typically have very small keys that are generally difficult to operate. Attempts to address this problem have resulted in cellular telephones being provided with voice recognition capability and computing devices being provided with handwriting recognition capabilities. However, such devices are still awkward to use and user input is slow.

Some manufacturers have made portable keyboards available for use with their mobile devices. However such portable keyboards generally need to be supported on a surface and may leave the user feeling cramped for space. Some users may even develop health problems such as carpal tunnel syndrome due to using such keyboards in un-ergonomic positions.

There remains a need for methods and apparatus for inputting of information into electronic devices.

The interface 120 includes an encoder 121, which includes a plurality of inputs 122, each one of the inputs corresponding to one of the plurality of sensors 106 on the user's fingers 108. The encoder 121 also includes at least one input 124, for receiving signals from the sensor 102 positioned on the user's thumb 104. In some embodiments a second sensor (not shown in Figure 1) may be positioned on the user's thumb, in which case the input 124 would also include a second input for receiving signals from the second sensor. The encoder 121 also includes an input 125 for receiving configuration commands and data for configuring the encoder.

Referring back to Figure 1, in one embodiment the sensors 106 and 104 each include conductive electrical contact points, each connected to a respective one of the inputs 122 and 124 by a plurality of conductors 114.

Referring again to Figure 2, the encoder 121 produces a signal at the output 123, in response to sensing a completed electrical circuit between one of the sensors 106 and the first sensor 102 when the sensors are brought into physical contact by the user. The signal at the output 123 includes a code that uniquely identifies which one of the sensors 106 was contacted by the sensor 102.

In one embodiment the interface 120 includes a transducer 131 and the encoder 121 includes an output 133 for producing a signal in response to each sensing of contact between one of the sensors 106 and the sensor 102. The signal at the output 133 is in communication with the transducer 131 for providing audible or tactile feedback to the user. For example, the transducer 131 may produce a "beep" or "click" sound. Alternatively, the transducer may be positioned in close

proximity to the user's hand and may produce a vibration or other disturbance that can be felt by the user. The audible or tactile feedback serves to confirm to the user that a data-item has been sensed.

The interface 120 further includes a map 126, which has an input 128 for receiving the signal from the output 123 of the encoder 121, and an output 130 for producing the data signal. The map 126 also includes an input 132 for receiving a mode selection signal, and an input 134 for receiving configuration commands and data for configuring the map. The map further includes a memory 127, such as a non-volatile flash memory device, for storing one or more association tables 129. The map 126 is operable to associate contact between the first sensor 102 and sensors 106 with data items in accordance with the association table 129 in the memory 127, and to produce the data signal representing the data item.

The interface 120 further includes a wireless transceiver 140, which has an input 142 for receiving the data signal from the output 130 of the map 126. The wireless transceiver 140 also includes an antenna 144, for producing a radio frequency signal representing the data signal and for receiving radio frequency signals representing configuration data and commands from a device 150. The wireless transceiver 140 further includes an output 148 for providing configuration commands and data to the input 134 of the map 126, and an output 146 for providing configuration commands and data to the input 125 of the encoder 121.

The wireless transmitter 140 may optionally include an output 145 which is in communication with a display 149 such as a liquid crystal display device (LCD) for displaying information to the user.

The interface 120 is in wireless communication with the device 150. The device 150 may be an electronic device including, but not limited to, a cellular

telephone, a handheld computing device such as a Personal Digital Assistant (PDA), a laptop or desktop computer, a vehicle mounted device such as a car stereo, an audio device such as an MP3 player, and a video device such as a DVD player. The device 150 includes a wireless transceiver 152, which includes an antenna 154 for receiving the radio frequency signal representing the data signal from the wireless transceiver 140, and for transmitting the radio frequency signals representing configuration data and commands to the wireless transceiver 140. The device 150 further includes an input interface 153 in communication with the wireless transceiver 152 for receiving the data signal from the wireless transceiver. In one embodiment the input interface 153 may include a keyboard port or a universal serial bus (USB) port.

In other embodiments, communication between the device 150 and the interface 120 may not involve configuration data and commands being sent to the apparatus by the device, in which case the interface 120 may include a wireless transmitter, instead of the wireless transceiver 140, and the device 150 may include a wireless receiver, instead of the wireless transceiver 152.

In one embodiment the wireless transceivers 140 and 152 are implemented as Bluetooth ® wireless devices. Alternatively the wireless transceivers 140 and 152 may be implemented as Universal Serial Bus (USB) wireless transceivers, which use ultra wide band communications to reduce power consumption of wireless devices. In other embodiments the wireless transceivers 140 and 152 may be eliminated and replaced by a wired connection to the device 150, such as a Universal Serial Bus (USB) cable and USB interface.

In other embodiments the device 150 may include an infrared port for receiving user input from an infrared transmitter and the wireless transceivers 140 and

152 may be implemented as infrared devices, which communicate by transmitting and receiving encoded infrared light signals.

Referring to Figure 3, in one embodiment the interface 120 is mounted in a housing 160, which further includes a battery compartment 164, for receiving a battery (not shown) that provides power to the encoder 121, the map 126, and the wireless transceiver 140. In this embodiment the housing 160, and the sensors 102 and 106 are mounted on a shaped covering such as a glove 162 shown generally at 162, such that when the glove is worn by the user, the housing is positioned on the back of the user's hand and the sensors are located in ergonomically favourable positions on the user's thumb 104 and fingers 108. Optionally, the glove 162 may also include the display 149, mounted on the glove such that when the glove is fitted on the user's hand, the display is positioned on the back of the hand. The glove 162 may be fabricated from a material that is breathable and stretchable, for example. The material may also be transparent or semi-transparent or may be a meshed fabric to make it lighter. The glove 162 also includes the conductors 114 connecting the sensors 102 and 106 to the interface 120. The conductors 114 may include flexible conductive traces that may be routed inside or outside the glove 162. Alternatively, the housing 160 and sensors 102 and 106 may be mounted on any other shaped covering that is adapted to fit on the user's hand.

In another embodiment the housing 160 may include a charging port (not shown) for receiving electrical energy supplied externally to the housing and for providing energy to recharge the battery.

The operation of the interface 120 is described in reference to Figures 1 and 2. Referring to Figure 1, desired data items to be input are selected by the user by contact between the sensor 102 on the thumb 104 and one of the sensors 106 on the fingers. This completes an electric circuit between one of the inputs 122 and one of the inputs 124 on the encoder 121. The encoder 121 activates each of the inputs 122 and senses when a particular circuit is completed, which indicates that a particular one of the sensors 106 has been activated. The

encoder 121 then produces the signal encoded with a code representing the selected one of the sensors 106 at the output 123.

When the user completes a circuit between one of the sensors 106 and the sensor 102, there is usually a small amount of vibration between the surfaces which results in the circuit being repeatedly completed, and then disconnected in a short time. This fluctuation is known as "bounce" and the encoder 121 includes a filter (not shown) that de-bounces the circuit, such that the contacting is treated as a single data item. The device 150 may optionally produce configuration commands and data for configuring the filter, which are transmitted by the transceiver 152 to the transceiver 140 and received at the input 125.

Other configuration commands and data may also be received at the input 125 of the encoder 121, for example, configuration data corresponding to common keyboard configuration parameters such as typematic repeat rate etc.

The signal produced by the encoder 121 at the output 123 uniquely identifies one of the sensors 106, which has been selected, but does not necessarily associate the sensor with a particular data item. In this embodiment the association is performed by the map 126 which receives the signal from the output 123 of the encoder 121 at the input 128. The signal produced at the output 123 is encoded with data indicating which of the sensors 106 has been contacted. The map 126 looks up an associated data item corresponding to the sensor, in the association table 129 stored in the memory 127. Advantageously, by not permanently associating certain sensors with specific data items, the sensors may be re-configured for different applications or devices.

The association table 129 in the map 126 is configured when a configuration command signal is received at the input 134, followed by data signals representing data items that are to be associated with particular sensors 106. The data signals are received at the input 134 of the map 126 and the association data is stored in the association table 129 in the memory 127. In

this embodiment, the memory 127 is large enough to store a plurality of association tables 129, and the map 126 is responsive to the mode selection signal at the input 132 to select one of the plurality of association tables 129 to be active. One of the sensors 106 may be configured to cause the mode selection signal to be generated when contacted by the first sensor 102.

Alternatively, the apparatus may include a mode selection actuator switch 168, shown in Figure 3 in communication with the map 126, which may be activated by the user to cause the map to select an association table or mode.

In another embodiment the mode selection signal is generated by activating one of a plurality of mode selector switches (not shown), each of the plurality of mode selector switches corresponding to one of the plurality of association tables 129. Advantageously, the mode selection signal allows the user to conveniently switch between different modes, which are suitable for particular electronic devices, specific activities, or specific software programs running on an electronic device.

The map 126 produces a data signal at the output 130, which is received at the input 142 by the wireless transceiver 140. The wireless transceiver produces a radio frequency signal representing the data signal at the antenna 144. The radio frequency signal is received at the antenna 154 of the transceiver 152, and the data signal is recovered from the radio frequency signal, and sent to the input interface 153.

The display 149, when included, may be configured to display information received from the device 150 via the wireless link. The display 149 may simply echo data items or may display other information provided by the device 150.

Referring to Figure 4, in a second embodiment of the invention, both the user's left hand 180 and the user's right hand 182 are used to input information. In this embodiment a first glove 184 is adapted to fit the user's left hand 180 and a

second glove 186 is adapted to fit the user's right hand 182. The gloves 184 and 186 include shaped coverings that conform to the user's index fingers 188, middle fingers 190, ring fingers 192, and small fingers 194. The gloves 184 and 186 further include shaped coverings that conform to the user's thumbs 196, for each of the gloves respectively.

Each glove 184 and 186 includes a first sensor 198 mounted on the gloves such that when fitted on the user's hands, the first sensor will be positioned on a tip of the user's thumbs 196 respectively. Similarly, a second sensor 200 is positioned spaced inwardly from the tip of the user's thumbs 196 respectively.

Each glove 184 and 186 further includes a plurality of finger sensors 210 mounted on the gloves such that when fitted on the user's hands, the sensors will be positioned on the user's fingers 188 - 194. The plurality of finger sensors 210 includes finger sensors 201 - 207. For sake of clarity the finger sensors, thumb sensors, user's fingers, and the phalanges of the user's fingers are commonly numbered for each finger on the user's hands 180 and 182.

The plurality of finger sensors 210 includes a sensor 201 positioned on the gloves 184 and 186 to be adjacent to a tip of a distal phalange 212, a sensor 202 positioned on the gloves to be spaced inwardly from the tip of the user's distal phalange, a sensor 203 positioned on the gloves to be on a middle phalange 214, and a sensor 204 positioned on the gloves to be on a proximate phalange 216, all on a palm side of the user's hands 180 and 182, respectively. The plurality of finger sensors 210 further includes a sensor 205 positioned on the gloves 184 and 186 to be on a side of the distal phalange 212, a sensor 206 positioned on the gloves to be on a side of the middle phalange 214, and a sensor 207 positioned on the gloves to be on a side of the proximate phalange

216, of the user's hands 180 and 182, respectively.

In this embodiment the plurality finger sensors 210 include conductive electrical contact points. The first sensors 198 each include a conductive strip and when the gloves 184 and 186 are fitted on the user's hands the conductive strips extend partway around a periphery of the tip of the user's thumbs 196 respectively. The second sensor 200 includes a conductive area shaped in the form of a cross. Alternatively, the second sensor 200 may be shaped in the form of a "T". Advantageously the shaped first and second sensors 198 and 200 facilitate ergonomically favourable conditions when contacting the plurality of sensors 201 - 207 with the first and second sensors. Each of the sensors 201 - 207 is connected to one of the inputs 122 of the encoder 121 , shown in

Figure 2. The first and second sensors 198 and 200 are each connected to one of the inputs 124 of the encoder 121. In this embodiment each of the gloves 184 and 186 include an interface housing 220 mounted on the gloves such that when the glove is worn by the user, the housing is positioned on the back of the user's hand as shown in Figure 3.

The sensor 201 and the sensor 202, on each of the user's fingers 188 - 194 are positioned such that movement of the user's thumbs 196 and/or fingers to bring the first sensor 198 into contact with the sensors 201 and 202 is easily accomplished without discomfort to the user. Accordingly the map 126 is configured such that the most frequently used data items are associated with contact between the first sensor 198 and the sensors 201 and 202 on each of the user's fingers thus permitting ergonomically favourable conditions when the sensors are in contact and when moving the user's thumb and/or fingers to perform the contact between the sensors.

Similarly, the sensor 201 , on each of the user's fingers is ergonomically favourably positioned for contacting by the second sensor 200. Accordingly the map 126 is configured such that further frequently used data items are associated with contact between the second sensor 200 and the sensor 201 on each of the user's fingers. Each of the plurality of sensors 210 may thus be

associated with two different data items, depending on whether they are contacted by the first sensor 198 or the second sensor 200.

The sensor 205, on the side of the user's index fingers 188 and small fingers 194 are also somewhat ergonomically favourably positioned for contacting by the first sensor 198. Accordingly the map 126 is configured such that some frequently used data items are associated with contact between the first sensor 198 and the sensor 205 on the side of the user's index fingers 188 and small fingers 194.

Some of the plurality of sensors 210 may be very difficult to contact with either the first sensor 198 and/or the second sensor 200. For example most users will find contacting the second sensor 200 with any of the sensors 203 and 204, to be quite uncomfortable and therefore these sensors are not considered to be ergonomically favourable positioned, an thus may only be used for infrequently used data items, or not used at all.

Advantageously, in associating sensors in ergonomically favourable positions with frequently used data items, hand movement is kept to a minimum when inputting information, thus reducing user fatigue and enabling the user to input information at a higher rate.

In other embodiments, other types of sensors may be used, such as pressure sensitive sensors, touch sensors, thermal or capacitive sensors etc.

Referring to Figure 5, a third embodiment of the invention is shown generally at 301. In this embodiment, the users right hand 182 or left hand (only a right hand is shown in Figure 5), is used to mimic the operation of a wheel on a wheel mouse or other similar input device. The user's hand 182 is covered by a glove 300, which includes a first plurality of sensors including sensors 302 mounted on the palm side of the glove, and sensors 307 mounted on the glove such that

when the glove is worn on the user's hand, the sensors 307 are disposed on the sides of the user's fingers. The glove 300 also includes a first sensor 304. The sensors 302, 307 and 304 operate in a similar fashion as the plurality of sensors 210, and the first sensor 198, described above in reference to Figure 4.

The glove 300 further includes a second plurality of sensors 306 mounted on a side of the glove such that when the glove is worn by the user the sensors will be disposed on the user's index finger 308, positioned in-between the sensors 307. The plurality of sensors 306 are positioned in closely spaced relation and each sensor includes a conductive electrical contact point, which is in communication with one of the inputs 122 of the encoder 121 shown in Figure 2.

In this embodiment an area of each sensor 306 is smaller than an area of the sensors 307.

In this embodiment the second plurality of sensors 306 is used to implement functionality similar to the wheel on the wheel mouse, by sliding the first sensor 304 down the side of the user's index finger 308, thus successively contacting adjacent ones of the second plurality of sensors 306 with the first sensor. The encoder 121 and map 126 are configured to produce a repeating data signal in response to each successive contact. The encoder 121 is configured to ignore contact of the sensors 307 on the user's index finger 308, when successive contacting of adjacent ones in the second plurality of sensors 306 is detected.

Alternatively the encoder 121 may be configured to produce a first repeating data signal when contacted by the first sensor 304 in a first direction, and a second repeating signal when contacted by the first sensor in a second direction, opposite to the first direction. The first and second repeating data signals provide signals that mimic the operation of the wheel on the wheel mouse. Such a repeating data signal may be used to cause a display, in an associated device to scroll up and down or to select an item from a list of items.

Referring to Figure 5, in one embodiment the glove 300 may be marked with symbols or letters 320 indicating specific associations between the sensors 302 and data items. Advantageously, the symbols or letters may be applied to a transparent covering 322, such as a vinyl or latex glove, which can be pulled over the glove 300 such that a user can temporarily have access to a visual association between sensors and data items while learning how to use the apparatus 301. In embodiments where the first sensor and the plurality of sensors include electrical contact points, the transparent covering would require correspondingly positioned holes to provide access to the contacts.

The following describes modes of operation of the apparatus, which may be activated by changing the mode select signal provided to the input 132 of the map 126 shown in Figure 2.

Two handed input mode

An embodiment for inputting information into an associated device using both of the user's hands 180 and 182 is described with reference to Figure 4 and Figure

6. Referring to Figure 6, one possible association of data items with finger sensors 201 - 207, for contact with the first sensors 198 is shown in the table at 250. For example, contacting between the first sensor 198 on the thumb 196 of the left hand, and the finger sensor 201 on the ring finger, produces a data item "a". Contacting between the first sensor 198 on the thumb 196 of the right hand, and the finger sensor 202 on the index finger, produces a data item "c". Similarly, one possible association of data items with finger sensors 201 - 207, for contact with the second sensors 200 is shown in the table at 252.

Advantageously, for the association shown in Figure 6 and when inputting text characters in the English language, approximately 57% of the text characters commonly include the data items "space", "e", "a, "n", "t", "o", and "i", and are thus associated with contacting between the first sensors 198 and the finger

sensors 201 adjacent the finger tips. Approximately 25% of the text characters commonly include the data items Y 1 "s", "u", "p", "c", "h", "l","r", and "w", which are thus associated with contacting between the first sensor 198 and the finger sensors 202 positioned spaced inwardly from the finger tip. A further 10% of the text characters commonly include the data items "Backspace", "d", T 1 "g",

"Enter", "m", "y", and "b", which are associated with contacting between the second sensors 200 and the finger sensors 201 adjacent the finger tips. A further 1% of text characters commonly include the data items "k" and "v", which are associated with contacting between the first sensors 198 and certain ones of the finger sensors 205 positioned adjacent the sides of the user's finger tips.

Consequently, in this embodiment approximately 93% of data items may be input by contacting either the first sensor 198 or the second sensor 200 with one of sensors 201 , 202, and 205, which are ergonomically favourably positioned on the distal phalanges of the user's fingers. Other less frequently used data items may be associated with less ergonomically positioned sensors. In general, the ergonomics of contacting any of the plurality of sensors 210 and the first or second sensors 198 and 200 may vary slightly between users. For example a user who plays an instrument such as a guitar, which conditions the fingers to awkward movements, may find some less ergonomic sensors of the plurality of sensors 210 to be easily contactable, while a person with mild arthritis may find the same sensor impossible to contact.

Further, by contacting the second sensor 200 and the finger sensor 207, the apparatus may be placed in a "shifted" mode, whereby uppercase characters and alternate characters may be accessed (e.g. the sensor 203, on the left hand "Peroid / ?" causes the interface 110 to produce a period when in the un-shifted mode, and to produce a "?" when in the shifted mode).

Advantageously with the association shown in Figure 6, data items frequently occurring in sequence in words associated with a particular language may be

associated with adjacently positioned sensors. For example, "e" and "s" are associated with sensors 201 and 202 on the middle finger of the left hand. Similarly, "e" and "r" are associated with sensor 201 on the middle finger and sensor 202 on the index finger of the left hand respectively. Further "t and "h are associated with sensors 201 and 202 on the middle finger of the right hand.

The data items "n" and "g" are both associated with the sensor 201 on the small finger of the right hand, and are selected by first contacting the sensor 201 with the first sensor 198 and then the second sensor 200. The data items "e" and "d" are both associated with the sensor 201 on the middle finger of the right hand, and are selected by first contacting the sensor 201 with the first sensor 198 and then the second sensor 200. Advantageously, these and other frequently used sequences of data items may be inputted in a single sliding movement between the above identified adjacently positioned sensors.

Numeric input mode

An embodiment for inputting numeric information is described with reference to

Figure 4 and Figure 7. In this embodiment numeric information is input using the user's left hand 180 for numbers 1 - 9, and the user's right hand for other data items usually located on a numeric keypad. The numeric input mode may be activated from the two handed input mode described above, by contacting the first sensor 198 and the finger sensor 207 on the user's left hand index finger.

In the numeric input mode, contacting the second sensor 200 and the finger sensor 207 on the user's right hand index finger activates a function key mode, in which each number key becomes a corresponding function key (i.e. "1" becomes "F1", "5" becomes "F5" etc), except for "F11" and "F12", which are associated as shown in Figure 7.

Contacting the second sensor 200 and the finger sensor 207 on the user's left hand middle finger returns the user to the mode described in the two handed input mode embodiment above.

Single handed input mode

An embodiment for single handed input is described with reference to Figure 4 and Figure 8, and illustrates a mode for inputting information into an associated device using only one of the user's left hand 180 and the user's right hand. In Figure 8, associations for each of the user's left and right hands are shown, although it should be understood that the user will choose one or the other, in accordance with the user's preference.

In the single handed mode, not all characters usually found on a keyboard are made available. The single handed mode may be particularly useful for inputting information into an associated device which is customized for messaging applications such as email.

The single handed mode may provide access to a numeric entry mode, such as that shown in Figure 7, which is activated by contacting the first sensor 198 and the finger sensor 207 on the index finger.

In this embodiment, the "shifted" mode may be accessed by contacting between the first sensor 198 and two of the sensors 210 on adjacent fingers simultaneously. For example, the sensors 201 on the index and middle fingers

188 and 190 may be associated with placing the apparatus in the shifted mode. Other data items such as the control key and the alt key may be associated with other sensors located on adjacent fingers, e.g. the sensors 201 on the middle and ring fingers 190 and 192, and the sensors 201 on the ring and small fingers 192 and 194.

Some data items require inputting three key combinations in an ordered sequence e.g. "ctrl-alt-del", which may be difficult to input using a single hand (or even with two hands). In this embodiment, the encoder 121 is configured to receive ordered sequences in response to contacting the sensor 207 on the index finger 188 three times in quick succession with the second sensor 200.

The map 126 includes entries corresponding to valid combinations of data items and the map produces a data signal corresponding to the desired combination for the following three data items that are input by the user.

Dial mode

An embodiment for inputting dialling information into an associated device, such as a cellular telephone is described with reference to Figure 4 and Figure 9. In this embodiment the user's left hand 180 is used for input, although either hand could be used. The dial mode is similar to the numeric input mode embodiment above, but has additional data items such as "send" and "end", commonly found on cellular telephones, associated with index finger sensor 207 and small finger sensor 204. Other data items may be associated with finger sensors 201 on the index finger and middle fingers respectively of the left hand, which are operable to activate speed dial and voice mail modes of operation of the cellular telephone.

While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims.
