During the TEDIndia conference, Pranav Mistry, inventor of SixthSense, a wearable device that enables new interactions between the real world and world of data, demoed several gesture control concepts and posted a video for all to see.
Among the concepts is an ultrasonic pen capable of drawing in three-dimension using IR LEDs and and an ultrasonic receiver. While not of interest to the average user, something like this could be a boon to architectures and engineers working on cutting edge designs.
But it's the augmented reality portion of the video that drew applause from the crowd. Armed with a tiny camera that acts as a digital eye, Mistry demonstrated how it's possible to take take a picture just simulating the gesture of snapping a photo without a digital camera in his hand.
"I'm more excited that you can actually take it outside. Rather than getting your camera out of your pocket, you can just do the gesture of taking a photo and it takes a photo for you," Mistry said.
