IR Gesture click is a mikroBUS add-on board that enables contactless gesture recognition, along with ambient light and proximity sensing capabilities with the APDS-9960 IC. This sensor integrates an LED and four directional photodiodes that receive the reflecting light. An internal gesture engine deduces the velocity, direction and distance of nearby objects (while cancelling the ambient light). You can implement a variety of gestures, from from basic directional swipes (up, down, left or right) to more complex combinations. Since the chip can work as a proximity sensor, the gesture engine can be configured to wake up automatically when a user's hand approaches. The board communicates with the target board MCU through the mikroBUS I2C interface, with an additional hardware inerrupt pin (INT). IR Gesture click uses a 3.3V power supply. |

The Gesture Board, carrying Microchip's MGSC3130 3D gesture recognition controller, brings a new approach to designing intuitive user interfaces. It's like a touchpad whose input area extends 10cm upwards into space. Users will be able to command an MCU or PC by gesturing with hands and fingers above the board, and by touching and tapping its surface. The board comes with an IDC cable connector. The silkscreen on the back of the board depicts various supported gestures (flicking, drawing circles, airwheels, taps and double taps and so on). The Gesture Board communicates over an I2C interface. For use with with a PC, a special I2C to USB adapter board is available (see 'Accessories'). |
