“The gesture is a natural method of human communication, one that is used subconsciously in everyday interpersonal communications,” said Mark Boyadjis, senior analyst and manager, automotive infotainment, for IHS Automotive. “Because of this, gestures can be used in control automotive infotainment functions ranging from navigation to satellite radio with minimum driver distraction. This, and other factors, will cause sales of proximity sensing and gesture recognition systems in cars to undergo a rapid expansion in the coming years.”
Compared to other types of emerging automotive HMI systems, proximity and gesture recognition will prove most valuable to end users and be the most widely applicable across different brands, regions, languages, and cultures, IHS predicts.
Gesture recognition is defined as the use of cameras or sensors to track and convert a user’s movements into inputs for the infotainment system without any physical touch input. This would include things like waving a hand to the left or right to change radio presets or go to the next song in a playlist, or turning the hand clockwise or counterclockwise to raise or lower the volume.
Proximity sensing is the use of smaller, less expensive proximity sensors, typically infrared technology, to detect the user’s hand or another object approaching the display or control knob. This technology may or may not understand a gesture but rather the presence of the hand or object in proximity. Proximity sensing can be used to bring up menus on a car’s display with frequently used functions, which disappear when not in use.
