Ams AG, a leading provider of high performance analog ICs and sensors, today released a new family of intelligent sensors that integrate six key sensing functions including gesture detection and Mobeam barcode emulation. The TMG399x product family is ideally suited for touchless gesture control and display management in smartphones, tablets and many other consumer electronics on the market today. Advanced gesture-recognition software developed by ams supports a wide range of gestures, enabling touchless control for consumer devices. Gesture detection utilizes four directional photodiodes to sense reflected IR energy, then converts this data into physical motion information including: velocity, direction and distance. As sensors continue to proliferate in today’s mobile devices, support for sensor hub architectures has become an important requirement to enable optimum system performance.
The TMG399x gesture software currently supports optimized Android drivers, and a fully-qualified gesture library is available for the Qualcomm ADSP sensor core on the Snapdragon 6xx and 8xx processor family for four-direction gesture, plus ALS, proximity, and all the other standard features. The ams gesture software offers expanded capability to include support for eight-direction gesture, push button and taps, and work is in-progress to support other industry-leading third-party sensor hub devices. The gesture engine features automatic ambient light subtraction, crosstalk cancelation, dual 8-bit data converters, power saving inter-conversion delay, 32-dataset FIFO, and interrupt driven I2C communication. It accommodates a wide range of gesture-detection requirements, from simple North-South-East-West gestures to more complex gestures, including simulated button pushing and taps. Power consumption and noise are minimized with adjustable IR LED timing and optimized gesture algorithms.
The TMG399x product family also integrates industry-leading color sensors from ams. Accurate color management and light intensity measurements are critical parameters for display management in portable devices operating under a wide range of light sources, including fluorescent, incandescent and sunlight. Proximity detection, composed of the IR LED and sensor, is optimized for object detection within 100mm and can be used to simplify a product’s user interface, such as intelligent on/off control of smartphone touchscreens. The proximity detection is factory-calibrated to a distance of 100mm, eliminating the need for OEMs to perform production-line calibration, and simplifying the end-product manufacturing. ams is making it easy for systems designers to integrate e-commerce functionality into smartphones and portable electronics.
