The MGC3130 is the world’s first electrical-field (E-field) based three-dimensional (3D) tracking and gesture controller. The chip is based on Microchip’s patented GestIC® technology and enables user command input with natural hand and finger movements in free-space. The GestIC Colibri Suite is processed on-chip and enables a wide range of gesture applications shortening development cycles of developers. Through its configurable sensing states mobile friendly power consumption as low as 150 microwatts can be realized.
