New Computer Interface Devices

Above is a video of what could be the next generation of computer interface. It is obviously very raw but if it were mounted in a mouse shaped device and made wirless it could be a winner. Actually it would be very similar to the Wiimote since the Wiimote uses accelerometers to read controller movement and Bluethooth to transmit that data to the controller.

Popular Science gave an invention award to the ring mouse. It uses ultrasonic pulses to detect the position of the ring and moves the cursor accordingly. Which technology, if any, do you think will come out on top?

See more details of the ring mouse below.

“Although the system looks a bit rough, it works flawlessly. A small speaker on the ring pumps out ultrasonic pulses, picked up by five microphones arrayed on a piece of plywood. A central processor calculates the ring’s position in space based on when each microphone receives each blast of sound and then correlates this to the cursor onscreen. The ring and sensors communicate 100 times a second, so the translation of hand movement to cursor is instantaneous.”
