Based on a report from Korean tech site Ddaily.co.kr, Samsung’s upcoming flagship Galaxy S IV may feature touch-less screen navigation. This means that by hovering your finger over the device and making hand gestures, you can select options such as answering phone calls, navigating your music player, etc.
Samsung chose Atmel’s maXTouch Series Touch for the S IV mainly due to it’s lesser battery strain than other screens. It utilizes what’s called Indium Tin Oxide (ITO,) providing a gesture sensor in the phone’s front facing camera.
This gesture based non-contact UI display is awesome, no doubt — but is it necessary? Correct me if I’m missing something here, but apart from needing to answer a call when your hands are covered with paint or grease, what’s the practical use of this feature?
