A new means of operation. To minimise distraction, developers are seeking alternatives to conventional switches and buttons. In addition, the controls of modern cars are meant to boast a fashionable design and advanced mobility technology. This means we are encounter touch displays not only on our smartphones, but also in the cockpit.
Another relatively new approach includes contactless technologies such as cameras, infrared, or radar.
AT A GLANCE
InnoSenT has been conducting research and development on radar-based movement detection for a long time. One application case is the contactless operation of multimedia systems and computers. Specially for automotive cockpits, there are already initial prototypes that reliably detect the movements. Thanks to further developments in the field of signal processing, it is now possible to detect many different gestures. The scope of functions is comparable to that of a video camera variant. The radar solution, however, can be produced at a significantly lower price.
invisible, contactless and anonymous gesture control
regardless of light and temperature conditions
resistant to noise and pollution
maximum design freedom through hidden placement
Currently, there are already two different types of systems available on the automotive market. Both utilise movement analysis for controlling the infotainment system. While one solution relies on video equipment, the other works with infrared. The already established infrared sensors detect only swipe gestures.
Gesture control via video camera recognises significantly more movement patterns than the sensor variant. This already allows you to accept calls or change the volume. This additional operating language, however, is very costly and presents a data protection dilemma, since it is constantly ready to make recordings. Neither variant currently offers an ideal solution.
Here, however, the radar experts from InnoSenT see an opportunity to create public acceptance for gesture control systems through a new technological approach: radar technology boasts advantageous properties for detecting movement patterns. It is ideal for creating a convincing system at prices that are in line with the market.
