GestIC Controller Enables One-step Design-in of 3-D Gesture Recognition

Microchip Technology recently announced a new addition to its patented GestIC family. The new MGC3030 3-D gesture controller features simplified user-interface options focused on gesture detection, enabling true one-step design-in of 3-D gesture recognition in consumer and embedded devices. Housed in an easy-to-manufacture SSOP28 package, the MGC3030 expands the use of 3-D gesture control features to high-volume, cost-sensitive applications such as audio, lighting, and toys.GestIC

The simplicity of gesture-detection integration offered by the MGC3030 is also achieved through Microchip’s free, downloadable AUREA graphical user interface (GUI) and easily configurable general-purpose IO ports that even allow for host MCU/processor-free usage. The MGC3030’s on-chip 32-bit digital signal processor executes real-time gesture processing, which eliminates the need for external cameras or controllers for host processing and allows for faster and more natural user interaction with devices.

The MGC3030 makes full use of the GestIC family development tools, such as Microchip’s Colibri Gesture Suite, which is an on-chip software library of gesture features. Intuitive and natural movements of the human hand are recognized, making the operation of a device functional, intuitive, and fun. Without the need to touch the device, features such as Flick Gestures, the Air Wheel, or the proximity detection perform commands such as changing audio tracks, adjusting volume control or backlighting, and many others. All gestures are processed on-chip, allowing manufacturers to realize powerful user interfaces with very low development effort.

Unique to GestIC technology, the programmable Auto Wake-Up On Approach feature begins operating in the range of 100-µW power consumption, enabling always-on gesture sensing in power-constrained applications. If real user interaction is detected, the system automatically switches into full sensing mode and alternates back to auto wake-up mode once the user leaves the sensing area. These combined features and capabilities provide designers with the ability to quickly integrate gesture detection features at price points that are ideal for high-volume devices.

Also available is Microchip’s Woodstar MGC3030 Development Kit (DM160226). The $139 kit is available via any Microchip sales representative, authorized worldwide distributor, or microchipDIRECT (www.microchip.com/Dev-Kit-012015a). The kit comes with the AUREA GUI, the central tool to parameterize the MGC3030 and the Colibri Suite to suit the needs of any design. AUREA is available via a free download at www.microchip.com/AUREA-GUI-012015a. The Colibri Gesture Suite is an extensive library of proven and natural 3-D gestures for hands and fingers that is preprogrammed into the MGC3030.

The MGC3030 featuring GestIC technology is available in a 28-pin SSOP package. Each unit costs under $2 each in high volumes.
