FIELD OF THE INVENTION
The present invention relates to wearable devices. More particularly, but not exclusively, the present invention relates to wearable devices such as earpieces with improved user interfaces.
BACKGROUND
Wearable devices of various varieties are becoming increasingly popular consumer devices. Yet numerous problems exist which may preclude or delay widespread adoption of wearable devices. One of these problems relates to the user interface associated with wearable devices. Wearable devices may be able to perform multiple functions some of which may be complex in nature. Yet, it is desirable to have a user interface which is simple, intuitive, and elegant in design. Further complicating the design of wearable devices is that wearable devices may be exposed to different environments and use conditions than other types of consumer devices. Some of these environments and use conditions create additional problems if using conventional user interfaces.
For example, consider the use of buttons on such a device. Buttons have the disadvantage of requiring a protective membrane around them. This results in a decrease of their tactile feedback as well as complicating the design due to the limitations of the protective membrane. For example, with repeated exposure to caustic or corrosive compounds such as sweat or cerumen, such membranes are well known to become brittle and crack over time, allowing for water contamination of the delicate microelectronic components contained within. Thus, various problems remain with wearable devices, including earpieces.

DETAILED DESCRIPTION
According to one aspect a new earpiece for use in multiple modalities is provided. The device may provide multiple functions including functions of interest to a user performing sports activities, the transmission of audio information for two way conversations, and the measurement of numerous biometric data sets. Of course, the earpiece may also perform additional functions.
Although such a device preferably performs a number of different functions, it is preferred that the wearable device be relatively simple and/or intuitive in operation. In addition, because the device may be used during sports activities it is preferred that the device be water resistant or otherwise adapted for harsh environments. Where the device is water resistant, it is preferred that the device allows the user to interact with it when in the water such as while swimming in a swimming pool, lake, or ocean.
The present invention provides for a new system and method for communication with the user as well as facilitation of device analytics. In particular, colorimetric light is used to give visual data and/or feedback to the user. The device may provide the user feedback over operational controls of the device, activate optional features, confirm gestural movements, allow for assessment of embedded device data such as device build, serial number, build date, etc, as well as to provide for an alternative method for software upload, download and analysis of data. The lights may also be used for other functions such as may be used for diagnostic purposes or to assist developers including for use in debugging.
FIG. 1 illustrates one example of a wearable device in the form of a set of earpieces 10 including a left ear piece 12A and a right earpiece 12B. Each of the ear pieces 12A, 12B has a housing 14A, 14B which may be in the form of a protective shell or casing. A light display area 16A, 16B is present on each of the ear pieces 12A, 12B. The light display areas 16A, 16B each provide for producing light of one or more colors. Lighting elements such as LEDS may be used as light sources to generate the light and light guides or other optics may be used to transmit the light from the light source to the display areas 16A, 16B.
Different colors of light may be used to visually indicate different information to uses. For example a visual display of red may be used to indicate that the battery is at a critically low level and needs to be recharged soon. If the battery is at a recommended charge level a visual display of yellow may be used. If the battery is at a stable level a visual display of green may be used. It is to be understood that battery level is merely one mode of operation of the device. The same lighting may be used to provide visual feedback regarding other functionality or modes of operation of the device.
In another mode of operation, the visual indicators may relate to charging of the battery using its case or other power source. For example, when the device is properly coupled to its charging case or other power source an LED (or plurality of LEDs) may show green (or another color). The LED may glow as charging initiates. If the device is not properly coupled to its charging case or seated poorly in the case then an LED (or a plurality of LEDs) may show red (or another color).
The device may be multi-modal so that based on the context of use the same visual indicators may take on different meanings. Thus, in the above examples, the visual display of red may indicate that the battery is at a critically low level and it may also indicate that the device is not properly coupled to its charging case. Thus, the same visual displays may have different meanings depending upon the mode of operation of the device.
Another mode of operation of the device relate to gestural movements. For example, where a user performs a gestural movement which is interpreted by the device the device may light or activate one or more lighting elements to confirm the gestural movement or to indicate that the gestural movement could not be interpreted.
Other modes of operation may include those associated with providing visual data, providing visual feedback, activating optional features, or other types of operations that may be desirable or appropriate for a particular device.
It is contemplated that where LEDs are used as light sources that a multi-color LED may be used such as a bicolor LED, tricolor LED or other type of LED. It is further contemplated that an array of different colored LEDs may be used. It is further contemplated that light from one or more LEDs may be communicated through a light pipe or light guide to provide a more aesthetically pleasing display to a user.
In addition to the particular colors of LEDs used, information may be communicated in other manners as well. This includes the number of LEDs or the sequencing of LEDs being lit, the duration that a LED is lit, or frequency of pulsations of light.
FIG. 2 illustrates another view of a set of earpieces. Each of the earpieces shown includes two LEDs 20A, 22A for the first earpiece 12A and two LEDs 20B, 22B for the second earpiece 12B. More or fewer LEDs may be used.
FIG. 3 is a block diagram illustrating a device. The device may include one or more LEDs electrically connected to a processor 30. The processor 30 may also be electrically connected to one or more sensors 32 and a transceiver 34 such as a short range transceiver using Bluetooth, UWB, magnetic induction, or other means of communication. In operation, the processor 30 may be programmed to convey different information using one or more of the LED(s) 20 based on context or mode of operation of the device. One way in which the processor 30 may determine the relevant mode of operation of the device is from data collected from one or more of the sensor(s) 32. For example, where the device is an earpiece, the sensor(s) may include an inertial sensor, one or more contact sensors, a bone conduction sensor, one or more microphones, a pulse oximeter, or other biological sensors. Thus, based on the status of different sensors, additional information about the mode of operation can be determined. Thus, for example, the processor may determine whether or not the earpiece is positioned on the ear in a proper position, whether or not the earpiece is being charged, or other contextual information.
FIG. 4 illustrates an example of LEDs of different devices. In this example, note there are multiple wearable devices each with one or more LEDs. As shown in FIG. 4 this includes a set of LEDs 40A associated with a left earpiece and a set of LEDs 40B associated with a right ear piece. Thus. LEDs from multiple devices may be used in concert or in combination to convey information.
FIG. 5 illustrates further examples of communicating using LED devices. A first configuration of LEDs 50 shows four LEDs of a first color. A second configuration of LEDs 52 shows four LEDs of a second color. A third configuration of LEDs 54 shows two LEDs of a first color and two LEDs of a second color. A fourth configuration of LEDs 56 shows one LED of a first color, two LEDs of a second color and a third LED of a third color. The four LEDs shown may be on the same ear piece or device or may be split between multiple ear pieces and devices.
FIG. 6 illustrates an app on a mobile device programmed to visually interpret colors or patterns displayed using LEDs. A first set of LEDs 40A are associated with a first device and a second set of LEDs 40B are associated with a second device. Each of the devices may be an earpiece within a set 42 of earpieces. A mobile device 60 is also shown with a camera 64. An app 62 may be stored on a non-transitory machine readable medium of the mobile device 60 and executed on a processor of the mobile device 60. As previously explained visual indicators such as LEDs or other lighting elements may provide feedback directly to users based on mode of operation or context. It is also contemplated that the visual indicators may be used to convey information to an app or other software application. The app 62 may access a camera 64 of the mobile device 60 to acquire imagery of the visual indicators. Any type of digital data may be conveyed by turning on and off the LEDs or other lighting elements. The digital data may be encoded in any number of different ways and any number of types of information may be represented.
One use of the app 62 is to interpret trace data sent from one or more device. Another use of the app 62 is to interpret visual flashes used to convey information about debugging protocols. Another use of the app 62 is to allow for identification of user stored databases. One of the advantages of conveying information in this manner is that it does not require the use of a serial port. This may be an important advantage when the earpieces are water tight and may be used while swimming. Nor does it require the use of a Bluetooth transmitter and receiver or other short range transceiver. The information conveyed can also include embedded device data such as device build, serial number, build date, etc. as well as to provide for an alternative method for software upload, download and analysis of data. Thus, any number of different types of data may be conveyed from a wearable device using one or more LEDs.
Therefore methods, devices, and systems which provide responsive visual feedback have been shown and described. Although specific examples have been set forth herein, numerous options, variations, and alternatives are contemplated. This includes variations in the type of device, the number of devices, the type of lighting elements, the number of lighting elements, the placement of lighting elements, the colors or lighting elements, whether or not light pipes are used, and other variations.
