Feature Description

4.1

Gesture Definition

A hand gesture is the movement of the hand to express an idea or meaning. The GestIC technology

accurately allows sensing of a user’s free space hand motion for contact free position tracking, as well as

3D gesture recognition based on classified movement patterns.

4.2

GestIC Library

MGC3140 is being provided with a GestIC Library loader (bootloader) which is stored on the chip’s Flash

memory. Using this loader, a GestIC Library can be flashed on the MGC3140 via I2C using, for example,

an embedded host controller or Microchip's Aurea GUI. The GestIC Library includes:

•

Colibri Suite: Digital Signal Processing (DSP) algorithms and feature implementations.

•

System Control: MGC3140 hardware control.

4.2.1.1

Position Tracking

The Colibri Suite’s Position Tracking feature provides 3D hand position over time and area. The absolute

position data is provided according to the defined origin of the Cartesian coordinate system (x, y, z).

Position Tracking data is continuously acquired in parallel to Gesture Recognition. With a position rate of

up to 200 positions/sec., a maximum spatial resolution of 150 dpi is achieved.

4.2.1.2

Gesture Recognition

The Colibri Suite’s gesture recognition model detects and classifies hand movement patterns performed

inside the sensing area.

Using advanced random classification based on Hidden Markov Model (HMM), industry best gesture

recognition rate is being achieved.
