The core of this solution is a chip based on the patented HALIOS principle (High Ambient Light Independent Optical System). Its unique attribute: Whether the sun is shining or you are driving at night, the system isn’t affected by ambient light. Just as little as by temperature fluctuations, scratches, and dust.
HALIOS is a sensor system working on an optical and capacitive basis at the same time. Both systems can be used simultaneously and can exchange information among each other. It is therefore possible to combine the known advantages of a capacitive switch with a touchless recognition of gesture provided by optical sensorics. Even low-end SMD infrared LEDs facilitate a range of up to 30 centimeters.
