    Abstract: A method of synchronizing digital content between a first mobile device and a second mobile device is disclosed. Device position and orientation data is received at a first application executing in an operating system of the first mobile device. Sensor data is used to determine at least two 3D points associated with a physical location of the second mobile device. At least two 3D points are used to determine an offset for the position, orientation and scale of the first mobile device relative to the second mobile device. The offset and digital content data captured by the first mobile device are shared over a network with a second application executing in an operating system of the second mobile device.

    Abstract: An electronic device may have a display such as an organic light-emitting diode display. Electronic devices may also include a number of sensors such as accelerometers and gaze detection sensors. A graphics processing unit (GPU) may render digital pixel values for pixels in the device display. Frames (F2) with long rendering times may cause latency. To reduce latency, an image frame may be displayed for an extended period of time (68) to wait for the subsequent frame (F2) to finish rendering. Once the subsequent image frame (F2) has finished rendering, the subsequent image frame may be displayed without delay. To increase the lifespan of the display, variable persistence may be used. Sensor data and other factors may be used to dynamically determine persistence for minimal motion blur and maximum display lifespan. Sensor data may also be used to determine refresh rates for different portions of the display.

    Abstract: An architecture for providing a legacy software application with touch gesture recognition includes an overlay software application and a converter plug-in software application. The overlay application is configured to intercept and detect touch gestures and provide gesture information to the converter plug-in application. The converter plug-in application converts the detected gesture information into data that the legacy application can use. The converted data is provided to the legacy application via an API. The touch gesture recognition is essentially unnoticeable by the user as the overlay application is positioned over the legacy application and is effectively transparent.

  • Patent number: 10546540
    Abstract: An electronic device may include a display such as a light-emitting diode display. The electronic device may be a head-mounted device that provides a virtual reality or augmented reality environment to a user. To reduce artifacts in the display, a display may be operable in both a normal scanning mode and a partial scanning mode. In the normal scanning mode, every row of the display may be enabled to emit light in each frame. In the partial scanning mode, only a subset of the rows of the display may be enabled to emit light in each frame. The display may have a higher refresh rate in the partial scanning mode than in the normal scanning mode. To ensure uniform transistor stress across the display, the scanning driver for the display may scan the disabled rows in the partial scanning mode even though the rows will not be used to emit light.

    Abstract: Disclosed are systems and methods for decreasing latency between an acquisition of touch data and processing of an associated rendering task in a touch sensitive device having a touch sensing system capable of producing touch data at a touch sampling rate and having a display system that displays frames at a refresh rate. In an embodiment, the system estimates at least one of (a) a period of time for sampling touch data from the touch sensing system, (b) a period of time for computing touch event data from sampled touch data, and (c) a period of time for rendering of a frame to a frame buffer. The system determines a period of time Tc for (a) sampling touch data from the touch sensing system, (b) computing touch event data from sampled touch data, and (c) rendering of a frame to a frame buffer, based at least in part on the estimate. The system determines a point in time Tr at which the display system will be refreshed from the frame buffer.
