We have covered plenty of awesome smart rings in the past. The RUI Smart Ring is quite interesting though. It has a multi-touch surface and sensors to help you control things around your home with gestures. The device can be put on any finger and supports finger, arm, and hand gestures. You can control multiple devices with it and even use it in virtual & augmented reality environment. This effectively replaces a remote, mouse, keyboard, trackpad, and an augmented reality controller.
RUI integrates remote control, gesture control, multi-touch control, augmented and virtual reality control into one. You can use it to control the electronics around you or even measure your performance when playing golf. Think about the possibilities here. You can pair your RUI with your Google GLASS to get even more done. The ring can also interact with infrared only home appliances as long as you get a Bluetooth to infrared converter between them. RUI will have an open SDK. Like what you see? You can find out more information on Indiegogo.
