    Abstract: The present disclosure provides systems and methods for using a linear resonant actuator (“LRA”) to determine a type of contact between a device and its surroundings. The LRA may be coupled to an amplifier by one or more switches. The audio amplifier may receive a signal from a microcontroller and transmit the signal the LRA when the switches are closed. When the switches are in an open position, the LRA may be actively sensing for the type of contact. The back EMF may be measured when the switches are open. The measured back EMF waveform may be used to determine the type of contact. When the signal is not being transmitted, the LRA may be passively sensing to determine whether the device was tapped.

    Abstract: Aspects of the technology provide a graphical display on a client device such as a smartwatch or other electronic display device. Content rendered by a non-emissive display element is augmented by an enhancement display element, for instance to change a color or illumination intensity of the content. The enhancement display element may include multiple illumination sources and light pipes that guide light from the light sources to specific regions along the display. Alternatively, the enhancement display element may be a transparent OLED or similar component, for instance to provide per-pixel illumination, highlighting and/or color enhancement to selected content items. In yet another configuration, the enhancement display element has a mask layer and a light element. The mask layer controls the amount of light reaching the non-emissive display element or viewable by a user. Each of these architectures provides rich enhancement to the content items generated by the non-emissive display element.

    Abstract: Aspects of the disclosure provide a hybrid smartwatch that incorporates digital technology with an analog timepiece in a wristwatch form factor. A digital display layer of a non-emissive material is configured to present notices, data, content and other information. An analog display layer includes one or more hands of the timepiece, and overlies the digital display layer. The hands may be controlled by a processor through micro-stepper motors or other actuators. Physical motion of the hands provides expressivity, for instance via visual mechatronic effects. This may include buzzing, clapping, providing stylized visual features, hiding or minimizing information, and revealing information. The information presented on the digital display layer is presented concurrently with the hand movement, in a manner that complements the hand motion. This provides a rich, symbiotic dual-display layer arrangement that enhances the capabilities of the digital and analog display layers.

    Abstract: Aspects of the disclosure provide a hybrid smartwatch that incorporates digital technology with an analog timepiece in a wristwatch form factor. A digital display layer of a non-emissive material is configured to present notices, data, content and other information. An analog display layer includes one or more hands of the timepiece, and overlies the digital display layer. The hands may be controlled by a processor through micro-stepper motors or other actuators. Physical motion of the hands is simultaneously coupled with arrangement of content or other elements on the display layer, which results in numerous types of hybrid visualizations. This includes temporal presentations using hourly, daily, monthly or other time scales. Shape-shifting of the watch hands between 2D and 1D arrangements can linearly focus on certain information. And various content-aware layouts can highlight, bracket, occlude or otherwise emphasize or deemphasize displayed information.

    Abstract: A method may receive a first audio signal data at a first device, the first audio signal data decoded using a microphone array. A method may determine that the first audio signal data includes an audio sequence relating to an information sharing request. A method may send a first signal. A method may receive a second signal via the microphone array responsive to the first signal. A method may verify that the second signal was sent from a direction of a voice associated with the audio sequence, the second signal including a second device identifier associated with a second device. A method may establish a wireless connection with the second device using the second device identifier.
