  • Patent number: 10558270
    Abstract: A method for determining non-contact gesture is applied to a device for the same. The device has an image sensor to detect an image sensing data, an inertial measurement sensor to detect an inertial sensing data, and a processor to determine if an object data is detected and to determine if an inertial event is occurred. The image sensing data in the same and/or adjacent image frame with the inertial events are excluded so that the image sensing data used to determine the gesture are those not influenced by the inertial events. Therefore, the accuracy of determining the gesture is enhanced.

  • Publication number: 20150335274
    Abstract: A physiological signals detection device has a light source connecting to a control unit, a light detector and a processing unit. The light detector has a pixel sensor array including multiple light sensing elements. The light source emits light through a lens to the human body to generate reflected light. The light detector receives the reflected light to generate a sensing signal. Since the light sensing elements respectively receive different reflected light from different directions, the light sensing elements receiving reflected light from the noise are easily selected and eliminated from calculating the physiology value. Therefore, the calculated physiology value is more accurate.
