STMicroelectronics’ ToF Sensing Technology Enables Innovative Social-Distancing Applications

STMicroelectronics announced that its FlightSense Time-of-Flight (ToF) technology has been adopted by Aura Aware, a Dutch startup company to develop a social distance maintaining device for preventing disease transmission.

Time-of-Flight sensors transmit photons and then calculate distance to the target based on the time it takes for the reflected photons to be received back by the sensor. Moreover, ranging accuracy is unaffected by surface characteristics of the target, such as clothing color or skin reflectivity, of the target, making FlightSense ideal for helping people to maintain social distancing.

The smart distance-awareness portable device based on ToF technology is suitable for use at retail counters and check-in desks. The device shows green and red signal to indicate if people are keep a safe minimum-distance or not.

“This innovative device from Aura Aware shows a highly creative use of our FlightSense technology. ST’s ToF sensors can help protect our health in many ways, ensuring both social distancing and touchless interaction with all kinds of products that we use every day,” said David Maucotel, Business Line Director, Imaging, STMicroelectronics.

The sensors can also help users avoid contact with surfaces, including self-service touchscreens, smart faucets, and push-button door openers, located in high-traffic areas. The speed and precision of ToF sensing enable FlightSense sensors to manage basic on/off control as well as to detect and interpret gestures like tapping and swiping for smart touchless human-machine interaction.
