Vehicle infotainment is motion-controlled

25 June 2014

Driver monitoring and gesture recognition controls media in a vehicle, with the Time of Flight 3D sensor from SoftKinetic and Melexis.

The two companies claim to have developed the first Time of Flight 3D sensor for automobile safety and infotainment markets. The MLX75023 features SoftKinetic DepthSense 3D Imaging technology and is manufactured in Melexis’ automotive-grade CMOS mixed signal process. It is claimed to be the highest resolution 3D sensor available and works in full sunlight.

The MLX75023 is a QVGA (320 x 240 pixel) resolution optical camera sensor. It can understand subtle human gestures, claims the company, as well as the shape, size and behaviour of objects and people inside the car. For example, drivers can adjust the temperature, radio station or make a phone call, using simple gestures. It is suitable for LED or laser illumination and sensor modulation up to 40MHz and packaged in a small glass BGA. It is qualified for AEC-Q100 grade 2.
