3D tracking and Gesture Sensing...without cameras!

Do you still think you need cameras for 3D-tracking? Ok maybe you're a little behind. Microchip offers a really cool chip! Microchip's GesticIC® is a 3D sensor technology uses electric field sensors to detect, track and classify user hand or finger.

With MGC3130 (i.e. the first device of the family) using a number of typically four-five receiver (Rx) electrodes and one transmit (Tx) electrode, the origin of electric field variations inflicted by the user's hand can be detected. Signals are processed by the GestIC® technology device in order to calculate the hand position relative to the sensing area in x, y, z data points, and classify the movement pattern into gestures in real time.

These are some features of MGC3130:

• Recognition of 3D hand gestures and x/y/z positional data
• High resolution of up to 150 dpi
• Integrated digital signal processing unit
• Low noise analog front end
• Frequency hopping against noise
• Digital interface
• On-chip Colibri gesture suite
