Microchip Technology Inc, a provider of
microcontroller, analog and Flash-IP solutions,
has announced its patented GestIC® technology,
which enables the next dimension in intuitive, gesturebased,
non-contact user interfaces for a broad range of end
products. The MGC3130 is the world's first electrical-field
(E-field)-based, 3D gesture controller, offering low-power,
precise, fast and robust hand position tracking with freespace
gesture recognition.
With power consumption as low as 150 microwatts in its
active sensing state, the MGC3130 enables always-on 3D
gesture recognition-even for battery-powered products
where power budgets are extremely tight. In fact, the
MGC3130's low-power design and variety of power modes
provide the lowest power consumption of any 3D sensing
technology-up to 90 per cent lower than camera-based
gesture systems.
GestIC technology achieves the exceptionally high
gesture-recognition rates required by today's consumer
products through its on-chip library - called the Colibri
Suite - of intuitive and natural human gestures. The
Colibri Suite combines a stochastic Hidden Markov model
and x/y/z hand-position vectors to provide designers with
a reliable set of recognized 3D hand and finger gestures that
can be easily employed in their products.
GestIC technology utilises thin sensing electrodes made
of any conductive material, such as Printed Circuit Board
(PCB) traces or a touch sensor's Indium Tin Oxide (ITO)
coating, to enable invisible integration behind the device's
housing. This allows for visually appealing industrial
designs at very low total system costs. Additionally, the
technology provides 100 per cent surface coverage,
eliminating "angle of view" blind spots found in other
technologies. With a detection range of up to 15 cm, the
MGC3130 is the ideal technology for products designed to
be used in close proximity for direct user-to-device
interaction.
