Elliptic Labs has turned its attention toward reinventing the optical proximity sensor for smartphones. Hardware-based optical sensors have been an indispensable part of every smartphone since their inception to turn off the screen and disable touch functionality when a user holds a device to their ear. By replacing these hardware components, with Elliptic Labs' “BEAUTY” – the first software-based solution to replace the optical proximity sensor – the unsightly black holes on the front of smartphone will be removed.

The result is a more esthetically pleasing design. The optical proximity sensor requires one rectangular black shape or two large holes on the screen, these sensors detect when users are in call mode so the touchscreen can be deactivated. Smartphone designers have long wanted to remove these unattractive holes on the faceplate of the phone, but without the proximity functionality, a user's cheek could accidentally trigger functions on the screen.

With Elliptic Labs BEAUTY product, ultrasound software delivers the proximity functionality, re-using the existing earpiece and microphone previously used only for audio. A potential game changer, Elliptic Labs' BEAUTY software is the only technology that can deliver the proximity functionality without using a physical hardware sensor. Elliptic Labs BEAUTY software solves some of the issues associated with today's optical proximity hardware sensors, reduces costs, and improves performance.

Optical proximity sensors can be unreliable in certain weather conditions or in response to variations in hair and skin color.
