  • Patent number: 10334240
    Abstract: Techniques of augmented reality device calibration are disclosed. In some example embodiments, a system calibrates a visual inertial navigation (VIN) camera of a head mounted display (HMD) device with at least one eye camera of the HMD device to generate multi-camera calibration parameters, calibrating the at eye camera(s) with a display module of the HMD to generate display calibration parameters, calibrating the IMU with the VIN camera to generate VIN calibration parameters, and calibrating the IMU to the display module using the multi-camera calibration parameters, the display calibration parameters, and the VIN calibration parameters.
    Type: Grant

  • Patent number: 8416211
    Abstract: A light sensitive screen includes at least one sensing element each being configured to detect a force applied to a position of the light sensitive screen and generate an electrical signal when a force is detected, and a sensor module configured to receive and process the electrical signal from the at least one sensing element. The sensor module may amplify the electrical signal from one of the at least one sensing element and generate an amplified signal, compare the amplified signal with a threshold and generate a comparing result, and generate a digital signal based on the comparing result, the digital signal including information as to whether the position of the light sensitive screen is touched.
