3D Tracking and Gesture Sensing MGC3030/3130 3D Gesture Controllers with GestIC® Technology The MGC3030/MGC3130 are single-chip solutions to enable 3D gesture control in almost any product, such as wireless speakers, radios, light switches and remote controls. The MGC3x30 are optimized for embedded usage, require no host intelligence or resources and come with a complete gesture portfolio. The Benefi ts of GestIC Technology Similar to capacitive touch sensing, GestIC technology uses E-field sensing to detect gestures. Electrodes remain invisible behind the device housing, allowing an aesthetically pleasing industrial design without the need for holes or other cut-outs typically required for cameras or infrared-based systems. Further benefits include: ■ Full surface coverage, no blind spots ■ Lighting independent ■ Build in adaptive noise fi ltering ■ Only gesture solution with built-in auto wake/sleep • <100 A sleep current ■ Low system complexity ■ Low costs The MGC3030/MGC3130 output direct and immediately usable results—everything is detected on-chip including gestures, approach, touch events and x/y/z 3D positions. The MGC3x30 controllers are true single-chip solutions for the next generation of user interface, enabling gesturebased UI applications for embedded products. Fast, Precise and Robust Implemented as a low-power mixed-signal System-on-Chip (SoC), the MGC3x30 controllers offer a rich set of smartfunctional features including: ■ 0 (touch) to 10 cm detection range ■ Fast report rate up to 200 Hz (5 ms) ■ Field upgradable on-board gesture suite ■ Digital interface (I2C) and confi gurable GPIOs On-Board Gesture Recognition Gesture recognition is performed on chip to eliminate the complexity and need for additional processing, a unique feature to GestIC technology shortening your time-to-market. The gesture suite gives the MGC3030/MGC3130 controllers the ability to recognize gestures while the rest of the system is powered down or in a power savings mode. It is fieldupgradable Gestures to ensure your system can accommodate and use additional gesture algorithms as they become available. Like speech and language, everybody’s hand gestures have a unique quality that differs in timing, amplitude and a broad range of other metrics. The integrated GestIC Technology Colibri Suite makes use of a Hidden Markov Model for high recognition rates of various gestures. This detects the subtle difference between deliberate gestures and general hand movement to limit response to unintended gestures. Approach Wake-up is primarily used to wake up the MGC3130 (and the rest of the system) when a hand approaches the sensing area. Flick Gestures are available as swipes or edge flicks in four directions: North, East, South and West. These are typically used for commands such as next, previous, on/off or up/down. The Airwheel Gesture is an intuitive input for up/down adjustments to levels and values. The rotations are also detected on chip. Sensor Touch detects touch, tap or double tap at any of the five receive electrodes. This is typically used for selection and confirmation commands. The Wave Gesture registers small finger movements and differentiates in the x- and y-direction. Applications include shuffle play control in an audio device. The Hold Gesture detects a steady hand to trigger events, best envisioned as the touchless enter key. Timing is configurable. The Presence Gesture enables intelligent back lighting and in the simplest manner. Position Tracking is available on the MGC3130. 6 Touch and 3D Gesture Control
