Google has won a patent that will enable a user to unlock their device by pointing their face at the built-in camera, also allowing the user access to their personal profile. This “face-to-unlock” patent lets multiple users share one “computing device.”
This technology would be great on Android devices, and would be cool to see along with the support for multiple users on Android devices.
Google has recently won a few pretty cool patents that will probably be used in Android devices before too long. Read about the “Seeing With Your Hand Patent” that Google was recently granted and the “Patent for Eye Tracking-Based Unlock System”.
