San Francisco, Sep 5 (IANS) Tech giant Google is working on a "Human Presence Sensor" (HPS) for upcoming Chromebooks, which could be used for face unlock or other long-awaited Chrome OS features.Earlier this year, in a blog post celebrating 10 years of Chromebooks, Google included a small teaser of what's next for Chrome OS.In it, there's a promise of using acesensor technologies for more personalized experiences," 9To5Google reported.While there has been significant work done over the last few months to make this human presence sensor work on a hardware level, there's only been one clue so far as to what Chrome OS will do with it.Specifically, if a Chromebook has an HPS, there will be an eye-shaped icon in the system tray, the report said.For now, while the feature is early in development, the icon is static, but it's plausible that Chrome OS will show a different icon, depending on whether or not it can detect your presence.The tech giant is developing the human presence sensor in collaboration with Antmicro, a "software-driven tech company developing open and modern industrial edge and cloud Al systems".Among other responsibilities, Antmicro appears to be working out how to work with the sensor hardware using open-source software where possible, the report said.This is not the first time that Google and Antmicro have worked together, as the two companies -- both Platinum Founding Members of the RISC-V Foundation -- collaborated to create the Coral AI developer board, along with some other projects. --IANS vc/ksk/
