Abstract: Systems and methods are disclosed that address the need for adaptive exposure within high dynamic range (HDR) images. Solutions can leverage recent advances in the use of virtual reality (VR) headsets and Augmented Reality (AR) displays equipped with infrared (IR) eye tracking devices. A gaze vector determined by the eye tracking device identifies one or more fixation points on the image that corresponds to an area where there exists a faulty exposure. The exposure around the fixation point can be adaptively corrected using image processing techniques. Using spatial adaptive exposure, the resulting image, a type of foveated image, can be rendered on a low dynamic range (LDR) display with sufficient detail.

Abstract: Aspects of the technology provide a symbiotic graphical display on a client device such as a smartwatch. The system includes at least one emissive display element and at least one non-emissive display element. The display elements are arrayed in layers or other configurations such that content or other information is concurrently aligned across the respective display surfaces of the different elements. A first set of content is rendered using the non-emissive display element while a second set of content is rendered using the emissive display element. Depending on characteristics or features of a given content item, that item may be rendered by one or both of the display elements. Certain content may be transitioned from the emissive display element to the non-emissive display element according to a time threshold or other criteria.

Abstract: According to an aspect, a method for distributed sound/image recognition using a wearable device includes receiving, via at least one sensor device, sensor data, and detecting, by a classifier of the wearable device, whether or not the sensor data includes an object of interest. The classifier configured to execute a first machine learning (ML) model. The method includes transmitting, via a wireless connection, the sensor data to a computing device in response to the object of interest being detected within the sensor data, where the sensor data is configured to be used by a second ML model on the computing device or a server computer for further sound/image classification.

Abstract: Systems and methods are provided in which physical objects in the ambient environment can function as user interface implements in an augmented reality environment. A physical object detected within a field of view of a camera of a computing device may be designated as a user interface implement in response to a user command. User interfaces may be attached to the designated physical object, to provide a tangible user interface implement for user interaction with the augmented reality environment.

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.
