  • Patent number: 10572024
    Abstract: A head-mounted display (HMD) tracks a user's hand positions, orientations, and gestures using an ultrasound sensor coupled to the HMD. The ultrasound sensor emits ultrasound signals that reflect off the hands of the user, even if a hand of the user is obstructed by the other hand. The ultrasound sensor identifies features used to train a machine learning model based on detecting reflected ultrasound signals. For example, one of the features is the time delay between consecutive reflected ultrasound signals detected by the ultrasound sensor. The machine learning model learns to determine poses and gestures of the user's hands. The HMD optionally includes a camera that generates image data of the user's hands. The image data can also be used to train the machine learning model. The HMD may perform a calibration process to avoid detecting other objects and surfaces such as a wall next to the user.

  • Patent number: 10235002
    Abstract: A capacitive touch sensor device comprising set of crossing X and Y electrodes whose crossing points form a two-dimensional array of nodes which define a touch sensitive area. As well as the main electrode spines which cross, referred to as zeroth order electrode branches, the electrodes have higher order branches, some of which interdigitate. By varying the dimensions of the electrode branches, such as width and length, the overall area of the X and Y electrodes can be varied relatively independently of each other. It is therefore possible to produce an electrode pattern in which the self capacitances of the X and Y electrodes have a certain ratio, e.g. unity, and thereby compensate for the aspect ratio of the touch sensitive area, and/or to have a certain absolute value, e.g. in order not to overload a touch-sensor controller to which the sensor is to be connected.

  • Patent number: 9983718
    Abstract: A signal to be used to propagate a freely propagating signal through a propagating medium with a touch input surface is sent. The freely propagating signal has been allowed to freely propagate through the propagating medium in a plurality directions to a plurality of receivers on multiple axes of the propagating medium. A received signal detected due to a touch input object contacting the touch input surface is received. The received signal includes the freely propagating signal that has been disturbed by the touch input object. At least a portion of the received signal is compared with one or more reference signals of one or more touch input object types. Based at least in part on the comparison a location of the touch input object contacting the surface is determined.

  • Patent number: 9804675
    Abstract: Described embodiments include a system and a method. A system includes a first ultrasound transmitter acoustically coupled to a conducting layer of a display surface and configured to deliver a first ultrasound wave to a selected delineated area. The first ultrasonic wave has parameters sufficient to induce a non-linear vibrational response in the conducting layer. A second ultrasound transmitter is acoustically coupled to the conducting layer and configured to deliver a second ultrasound wave to the selected delineated area. The second ultrasonic wave has parameters sufficient to induce a non-linear vibrational response in the conducting layer. A controller selects a delineated area in response to an indication of a touch to the display surface, and initiates delivery of the first and second ultrasonic waves. A convergence of the first and second ultrasonic waves at the selected delineated area produces a stress pattern perceivable or discernible by the human appendage.

  • Patent number: 9639234
    Abstract: Methods, devices, and non-transitory process-readable storage media automatically configure or reconfigure input mechanisms to provide user inputs to simultaneously-active applications with input mechanisms that conflict. An embodiment method performed by a processor of a computing device may include recognizing that an overlapping control condition exists between simultaneously-active applications when a first control element of a first application and a second control element of a second application are configured to receive respective user inputs via a common input mechanism. When the processor determines that an overlapping control condition exists, available input mechanisms of the computing device may be identified, and one of the identified available input mechanisms may be reconfigured to provide the user inputs for one of the first control element or the second control element while the overlapping control condition exists.
