Multi-Touch Without a Touch Screen vs. Apple

Microsoft has stepped up with a challenge to the Apple iPhone’s lauded multi-touch interface. The PC maker released their innovative SideSight system last week at the User Interface in Software and Technology Symposium. The technology allows users to control actions on a cell phone screen by moving their fingers along side the device. Infrared sensors pick up motions up to 10 centimeters away and translate them into movement on the screen.
