STMicroelectronics has offered silicon chips to enable new zForce AIR touch-sensing modules from optical sensor tech firm Neonode. These include advanced mixed-signal SoC and STM32 microcontroller which, says ST, offer touch-control precision in real-time and low power consumption.
AIR Touch Sensors are ideal for integration in a wide range of applications, such as: PCs/Tablets, TVs/Monitors, Printers, Mechanical key replacement, White goods, Smart furniture, Interactive mirrors, Elevator panels, eReaders, Instruments, Vending Machines, ATM/POS terminals, Robotics, Range finders, Collision detectors and much more
The new touch-sensors use a programmable mixed-signal custom System-on-Chip (SoC) and an STM32 Arm Cortex microcontroller from ST for scanning laser diodes and IR beams to determine the exact position and movements of fingers, hands, or other reflective objects in the light path.
“Multiple objects can be tracked simultaneously and interpreted as touches or gestures with extreme accuracy: the coordinates are relayed up to 500 times per second with virtually zero delay”, ST claims
Neonode’s compact, low-power, and easy-to-use modules enable instant touch interaction on any device with a USB or I2C interface and work with any type of display or surface, including steel, wood, plastic, glass, skin, or even nothing, able to detect touch interactions in mid-air.
The innovative modules use laser-generated infrared light to track touch or gesture control, and are said to offer millimeter precision and an ultra-fast response.
The modules are available for immediate shipment worldwide through Digi-Key Electronics. They are on display on ST’s stand at Embedded World 2018 (February 27 – March 1, Nuremberg).
