If you're one of the select group of iPhone owners who feels that their device simply doesn't have enough touch input options, Canopy is showing a new accessory at CES 2013 that more than addresses that problem. Called the Sensus, it's a case for the iPhone 4, 4S and 5 that bestows the devices with additional touch surfaces on the back and right side.
The Sensus, which will sell for between US$59 and $99 when it arrives this summer, connects to the phone's 30-pin or Lightning connector for power and offers a passthrough for charging and data. When used with apps specifically designed to take advantage of it, the case adds 10 points of multitouch input.
