Description:
DISTRIBUTED HAPTICS FOR WEARABLE ELECTRONIC DEVICES

TECHNICAL FIELD

The present disclosure relates to haptic output devices useful with wearable electronic devices.

BACKGROUND

Wearable electronic devices provide enhanced user experience using haptic or tactile feedback. Current haptic feedback systems typically employ a mechanical system using a motor that causes a vibration in a member disposed within the device. The motors used to drive such motor-driven haptic feedback devices are typically quite bulky and present a significant power demand. Furthermore, such haptic feedback devices provide a "global" haptic feedback, since the feedback is not supplied to a specific location and instead causes the device itself to vibrate.

The ability to provide a structured haptic feedback in which the haptic pattern, timing, displacement and/or frequency are variable and may be adjusted to provide haptic feedback corresponding to an occurrence of a specific event rather than a "general" notification is of value since such notifications do to require the user to view the portable electronic device to determine the nature of the message or identify which specific event has occurred.

In order to be perceptible to the user, a haptic actuator must possess certain characteristics. Both the oscillatory frequency and the displacement of the haptic actuator represent factors perceptible to the device user. Human frequency perception levels at the fingertips lie between 0 Hertz (Hz) to 200 Hz. Human displacement perception levels at the fingertips lies between 10 micrometers (μιη) and 200 μιη. Generally, the higher the oscillatory frequency, the smaller the displacement to provide a perceptible haptic output. The two point discrimination threshold, the index of the smallest perceivable spatial resolution, is about 2 millimeters (mm) at the fingertips for mechanical stimulations and about 4mm to 6mm at the wrist.

DETAILED DESCRIPTION

The systems and methods described herein provide an enhanced user experience by providing a selectively configurable haptic output on the external surface of a wearable electronic device that contacts a user's skin surface. One or more displaceable members operably coupled to the wearable electronic device may be displaced or moved, and various displacement parameters of the displaceable member (direction, speed, etc.) may be used to alter, control, or adjust one or more haptic output parameters (pattern, displacement, frequency, etc.). In one embodiment, the wearable electronic device may include a wristwatch having a rotatable bezel on the watch face and a configurable haptic output on the back of the watch case (proximate the wrist of the user). User inputs received via the bezel may alter, control, or adjust the haptic output applied to the user's wrist.

In devices worn proximate a user' s skin, the user' s skin may provide the capability for supplying haptic feedback using a dynamic, configurable, and/or complex haptic output. Such broad configurability provides designers with a multitude of options to de-clutter the user interface on wearable electronic devices. The use of haptic feedback on small form factor and wearable electronic devices provides the user with a lifestyle that is not dominated by a display, but instead by an intuitive, timely, and discrete interface using tactile or haptic feedback. Moreover, the use of a displaceable member as an input device may beneficially permit the use of the wearable electronic device as the user provides input. For example, rather than obscuring a portion of the device display with an input "button" or "keyboard," the use of a displaceable member may permit the user to interact with the display while providing input to the device (e.g. , send data to the device, receive notifications from the device). In one example, a user may rotate a watch bezel to scroll through a list containing a plurality of options and may "press" or "click" the bezel to select one of the plurality of options. Such an arrangement beneficially permits the user to continue to use the watch face while examining the list of options and selecting one of the options.

The systems and methods described herein allow for the creation of localized haptic feedback that enhances the user experience, particularly with small form factor wearable electronic devices. The systems and methods described herein provide such enhanced user experience by mapping the movements of a moveable member coupled to the wearable electronic device to the haptic output patterns generated by the device. In one embodiment, such may be accomplished using a number of small haptic actuators disposed in a pattern on the back of a watch case. The rotation of the watch bezel in a clockwise or counterclockwise direction may be mapped to the haptic output patterns applied to the user's wrist. Such output may also be used to provide the user with notifications according to preset settings, navigational assistance, and similar.

As used herein, the term "wearable electronic device" refers to any electronic device capable of being attached, affixed, or placed proximate at least a portion of the device user' s body. Example wearable electronic devices may include, but are not limited to, eyewear (e.g. , Google Glass ® , Google, Inc. Mountain View, CA); pendants, bracelets, braces, broaches, rings, watches, and similar wearable devices or fashion appurtenances. As used herein, the terms "top," "bottom," "up," "down," "upward," "downward," "upwardly," "downwardly" and similar directional terms should be understood in their relative and not absolute sense. Thus, a component described as being "upwardly displaced" may be considered "laterally displaced" if the device carrying the component is rotated 90 degrees and may be considered "downwardly displaced" if the device carrying the component is inverted. Such implementations should be considered as included within the scope of the present disclosure.

As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. It should also be noted that the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise.

FIG 1 depicts an illustrative wearable electronic device 100 that includes a housing 102, a displaceable member 120 operably coupled to the housing 102, and a configurable haptic output device 130, in accordance with at least one embodiment of the present disclosure. As depicted in FIG 1, by executing one or more sets of machine-readable instructions, all or a portion of a configurable circuit 110 may be transformed into a dedicated haptic control circuit 112. The haptic control circuit 112 may receive input from the displaceable member 120 via input interface circuitry 114. The haptic control circuit 112 may output one or more signals to the configurable haptic output device 130 via output interface circuitry 116. In embodiments, user interaction with the displaceable member 120 causes the generation of an input signal 122 that includes information and/or data

representative of one or more displacement parameters. Such displacement parameters may include, but are not limited to, a displacement direction (clockwise rotation, counterclockwise rotation, planar displacement along x- and _ -axes, perpendicular displacement along a z-axis, etc.) , a displacement speed or velocity, a displacement frequency, or combinations thereof.

The haptic control circuit 112 receives the input signal 122 at an input interface circuit 114. Responsive to the receipt of the input signal 122, the haptic control circuit 112 generates an output signal 132 at the output interface circuit 116. The output signal 132 includes information and/or data indicative of one or more haptic output parameters. The one or more haptic output parameters may include, but are not limited to, a haptic output pattern, a haptic output direction, a haptic output displacement, a haptic output rhythm, and/or a haptic output frequency.

The housing 102 may have any size, shape, configuration, and/or geometry capable of being worn or otherwise disposed proximate the body of the device user. In some implementations, the housing may be in the form of a watch, pendant, necklace, eyewear, broach, or other decorative or functional jewelry or similar. The housing 102 may be metallic, non-metallic or any combination thereof. The housing may be affixed or attached to the device user via one or more straps, belts, fasteners, hooks, or similar.

The configurable circuit 110 may include any number and/or combination of devices and/or systems capable of executing machine-readable instructions. The configurable circuit 110 may include any number and/or combination of electrical components and/or semiconductor devices. In embodiments, the configurable circuit may be partially or wholly composed of hardwired components. In embodiments, the configurable circuit may include one or more processors situated in separate components, or alternatively, may comprise one or more processing cores embodied in a single component (e.g., in a System-on-a-Chip (SOC) configuration). Example processors may include various x86-based microprocessors available from the Intel Corporation (Santa Clara, CA) and include those in the Pentium ® , Xeon ® , Itanium ® , Celeron ® , Atom ® , Core i-series product families. The configurable circuit 110 may include devices and systems such as, digital signal processors (DSPs), reduced instruction set computers (RISCs), application specific integrated circuits (ASICs), programmable gate arrays (PGAs), or similar.

The configurable circuit 110 executes machine-readable instructions that may include program code, instructions, or similar logic configured to transform at least a portion of the configurable circuit 110 to a dedicated and particular haptic control circuit 112. Either or both the configurable circuit 110 and/or the haptic control circuit 112 may variously perform activities related to reading data, writing data, processing data, formulating data, converting data, transforming data, etc. The configurable circuit 110 and/or the haptic control circuit 112 may be communicably coupled to an input interface circuit 114 and/or an output interface circuit 116.

Information and/or data (e.g., instructions, data structures, program data, and similar) may be stored or otherwise retained in storage device 118. The storage device 118 may include any number and/or combination of storage devices and/or storage systems capable of retaining, holding, or otherwise storing digital data. In embodiments, the storage device 118 may include one or more non-transitory storage media, such as one or more magnetic storage media, one or more optical storage media, one or more atomic or molecular storage media, one or more electrically erasable programmable read only memory (EEPROM) storage media, or combinations thereof. The displaceable member 120 may include any number and/or combination of devices and/or systems capable of generating the input signal 122 in response to a user displacing, moving or otherwise transitioning the displaceable member 120 from at least a first position or location to at least a second position or location. The displaceable member 120 may be pivotably, slideably, rotatably, translationally, or otherwise moveably coupled to the wearable electronic device housing 102. In some implementations, all or a portion of the displaceable member 120 may form all or a portion of a decorative portion of the wearable electronic device housing 102. In some implementations, all or a portion of the displaceable member 120 may form all or a portion of a functional portion of the wearable electronic device housing 102. For example, the displaceable member 120 may form all or a portion of a functional or decorative bezel surrounding a crystal on a wristwatch.

The displaceable member 120 may be displaceable in a plurality of directions, for example rotatably displaceable, planarly displaceable (e.g. , along or in an X-Y plane disposed parallel to the housing 102), perpendicularly displaceable (e.g. , along a Z-axis disposed perpendicular to the housing 102), or any combination thereof. For example, a displaceable member in the form of a watch bezel may be rotatably displaceable about the watch crystal and may be perpendicularly displaceable along an axis perpendicular to the watch crystal. Such a configuration may advantageously permit the rotation of the watch bezel/displaceable member 120 by the user to scroll through a number of options and the displacement of the watch bezel/displaceable member 120 along the perpendicular axis to select an option from the number of options.

The configurable haptic output device 130 may include any number and/or combination of haptic output devices and/or haptic output systems capable of providing a haptic output perceptible to a user when the wearable electronic device 100 is placed proximate the user. In embodiments, the configurable haptic output device 130 may include a plurality of individual haptic output devices or "tactors" 134A- 134n (collectively, "tactors 134") arranged in a pattern on at least a portion of an exterior surface of the wearable electronic device 100. For example, the configurable haptic output device 130 may include three (3) or four (4) individual tactors 134 arranged in a pattern on the lower surface of the back of a watch case.

The tactors 134 forming the configurable haptic output device 130 may be individually controlled by the haptic control circuit 112. For example, the haptic control circuit 112 may selectively control the timing (i.e. , the sequencing) of the individual tactors 134 included in the configurable haptic output device 130 such that some or all of the tactors 134 operate in a sequential manner or such that the tactors 134 operate sequentially with a delay period interposed between at least some of the tactors 134. In another example, at least a portion of the tactors 134 may operate in parallel (i.e. , contemporaneously or

simultaneously) while other tactors operate sequentially. In addition, or alternatively, the haptic control circuit 112 may selectively control the displacement, output frequency, and/or output rhythm of each individual tactor 134 included in the configurable haptic output device 130. Advantageously, since the output parameters of each tactor 134 included in the configurable haptic output device 130 may be individually controlled and/or adjusted by the haptic control circuit 112, a large number of potential tactor output configurations/patterns may be generated by the haptic control circuit 112.

The tactors 134 may include any number and/or combination of devices and/or systems capable of providing a physical displacement at a defined intensity and frequency such that a user is aware of the physical displacement of the tactor 134. The tactors may include any current or future developed haptic feedback device and/or system. Example tactors 134 include, but are not limited to, linear resonant actuators (LRAs), eccentric rotating mass (ERMs) motors, piezoelectric actuators, microfluidic actuators, electroactive polymer actuators or combinations thereof. In some implementations, the tactors 134 may be covered by an elastomeric coating to provide a water-proof, perspiration-proof system when disposed on an exterior surface of a wearable electronic device 100. In some implementations, the tactor 134 may have a displacement of about 25 micrometers (μιη) or less; about 50 μιη or less; about 75 μιη or less; about 100 μιη or less; about 150 μιη or less; or about 200 μιη or less. In some implementations, the tactor 134 may have an oscillatory frequency of about 10 Hz or less; about 25 Hz or less; about 50 Hz or less; about 75 Hz or less; about 100 Hz or less; about 150 Hz or less; or about 200 Hz or less. In some implementations, the spacing between adjacent tactors 134 may be about 1 mm or less; about 2 mm or less; about 4 mm or less; about 5 mm or less; about 6 mm or less; or about 10 mm or less.

embodiment of the present disclosure. FIG 3B provides a front view of an embodiment of an illustrative wearable electronic device 300 in the form of a wristwatch, in accordance with at least one embodiment of the present disclosure. FIG 3C provides a rear view of an embodiment of an illustrative wearable electronic device 300 in the form of a wristwatch having three (3) tactors 134 disposed on the rear of the watch case, in accordance with at least one embodiment of the present disclosure. FIG 3A provides a rear view of an embodiment of an illustrative wearable electronic device 300 in the form of a wristwatch having four (4) tactors 134 disposed on the rear of the watch case, in accordance with at least one embodiment of the present disclosure.

As depicted in FIGs 3 A, 3B, 3C, and 3D, the wearable electronic device 300 includes a watch face 312 that is at least partially surrounded by a bezel which functions as the displaceable member 120. The displaceable member 120 is rotatably coupled to the wearable electronic device 300 and may be displaced (i.e. , via rotation) in a clockwise direction 314A and in a counterclockwise direction 314B. In the illustrated embodiment, the direction of rotation may alter or adjust one haptic output parameter, such as the direction of rotation of the tactors 134 forming the configurable haptic output device 130 on the back of the watch case. In the illustrated embodiment, the speed with which the bezel is rotated may alter or adjust one haptic output parameter, such as the intensity of the tactors 134 or the oscillatory frequency of the tactors 134.

In some implementations, the displaceable member 120 may be displaceable in one or more different directions, such as vertically downward 314C. Such may be accomplished, for example, by pressing or "clicking" the displaceable member. Other displacements are possible. For example, the displaceable member 120 may be pinned at one or more pivot points that facilitate the "rocking" or "pivoting" of the displaceable member about the pivot point. In the wristwatch example depicted in FIGs 3A, 3B, 3C, and 3D, such may be accomplished, for example, by pinning the watch bezel at the 3 o'clock and 9 o'clock positions such that the bezel pivots about an axis through the 3 o'clock and 9 o'clock positions. Alternatively, again using the example wristwatch depicted in FIG 3, the bezel/displaceable member 120 may be pinned at the 12 o'clock and at the 6 o'clock positions such that the bezel pivots about an axis through the 12 o'clock and 6 o'clock positions

In one embodiment exemplified by watch case 320, the configurable haptic output device 130 may be disposed on the rear surface of the watch case 320. In such embodiments, the configurable haptic output device 130 may include three (3) tactors 134A, 134B, and 134C disposed in a regularly spaced, triangular, pattern. The spacing 322 between the tactors 134 may be about 1.5 millimeters (mm) or more; about 2.0 mm or more; about 2.5 mm or more; about 3.0 mm or more; about 4.0 mm or more; or about 5.0 mm or more. In some implementations, the direction of rotation of the displaceable member 120 may determine the direction of rotation of the tactors 134 included in the configurable haptic output device 130. For example, if the displaceable member 120 is rotated clockwise 314A, then the haptic output pattern may sequence in a corresponding clockwise pattern 324A. Conversely if the displaceable member 120 is rotated counterclockwise 314B, then the haptic output pattern may sequence in a corresponding counterclockwise pattern 324B.

In another embodiment exemplified by watch case 330, the configurable haptic output device 130 may be disposed on the rear surface of the watch case 320. In such embodiments, the configurable haptic output device 130 may include four (4) tactors 134A, 134B, 134C, and 134D disposed in a regularly spaced, square, pattern. The spacing 322 between the tactors 134 may be about 1.5 millimeters (mm) or more; about 2.0 mm or more; about 2.5 mm or more; about 3.0 mm or more; about 4.0 mm or more; or about 5.0 mm or more. In some implementations, the direction of rotation of the displaceable member 120 may determine the direction of rotation of the tactors 134 included in the configurable haptic output device 130. For example, if the displaceable member 120 is rotated clockwise 314A, then the haptic output pattern may sequence in a corresponding clockwise pattern 334 A. Conversely if the displaceable member 120 is rotated counterclockwise 314B, then the haptic output pattern may sequence in a corresponding counterclockwise pattern 334B.
