Our relation to our connected objects is evolving. Typical human to machine interfaces (HMI) are currently manifested through a keyboard, mouse or touch panel. However, new and more intuitive ways to interact with consumer electronics are being developed. II-VI provides high quality, high performance components for new HMI designs. Our vertical cavity surface emitting lasers (VCSELs) are ideal for optical touch sensors situated on a car’s dashboard or steering wheel. VCSEL arrays provide infrared cabin illumination and structured light projection to enable gesture recognition. Our optical filters isolate the returning VCSEL signal over a wide field of view to improve the sensors’ accuracy and sensitivity, whether in intense sunlight or at night time. Active coatings such as indium tin oxide (ITO) can also be deposited on our micro-optics in complex patterns and used to monitor light leakage from a physically damaged sensor.
