Similar to capacitive touch sensing, Microchip‘s GestIC technology uses E-field sensing to detect gestures. Electrodes remain invisible behind the device housing, which allows you to create an aesthetically pleasing user interface design without the need for holes or other cutouts that are typically required for cameras or infrared-based systems.
Benefits:
True single-chip gesture solution for embedded usage
* From 0 (touch) to 20 cm detection range
* Very low-power design
* No detection blind spots
* No ambient influences (light/sound)
* Use of thin, low-cost sensing electrodes, for example a standard PCB
* Highest gesture detection reliability
* Active noise handling
* 44–100 kHz carrier frequency; no RF interference
You can add simple and intuitive 3D gesture control to almost any product with the world’s first electrical near–field (E-field) 3D gesture and motion tracking controllers. Based on its patented GestIC® technology, these single-chip solutions perform gesture detection and motion tracking without requiring host processing.
They come with a complete gesture portfolio that enables command input with natural hand and finger movements in free space to create innovative, compelling and user-friendly interfaces in a variety of embedded applications, including:
– Automotive
– Notebooks/PC peripherals
– Audio products
– White goods, appliances and air conditioning control
– Home automation
– Light switches
– Industrial and medical switches
– Electronic readers
– Game controllers
The MGC3030/3130 contain all the building blocks to develop robust 3D gesture input sensing systems. Implemented as a low-power, mixed-signal, configurable controller, they provide a large set of smart functional features including an integrated signal driver, a frequency adaptive input path for automatic noise suppression and a Digital Signal Processing (DSP) unit.
