BPI-PC101 gesture recognition module
Contents
Introduction
The PC101 integrates an ambient light (ALS) sensor, a proximity sensor (PS) and 6-D gesture sensors with built-in IR LED. It is used in notebook PCs, smartphones, MIDs (mobile internet devices),PNDs (portable navigation devices), e-books, tablet PCs, flat-panel televisions, etc. for extending battery life and for better user experience. Ambient light sensor optimizes the screen brightness to extend battery and to increase battery life. Proximity sensor (PS) measures the IR reflection intensity which correlates to the distance of the object. Proximity sensor enables the device controller to turn off the LCD back-light and the touch-screen sensor when the device is held close to your ear, placed inside the pocket, purse, or bags. This function saves the battery power and avoids unintended touch-screen trigger. Proximity sensor can also work as a device wake-up sensor by sensing the user waving the hand in front of the device. The 6-D gesture sensor detects the waving of palm in front of the screen in 6 directions left, right, up, down and z-axis. The hand gesture without the need to touch the screen adds new way of human device interaction. For example, the gesture can be used to accept a phone call in the hand-free mode while the user is driving in a car. In another example, the user wave to the screen to advance or retract in the picture viewing mode without worrying the food stains from the fingers to be left on the screen.
