Want to add more touchable space to your iPhone? Don't want to obstruct the display with your fingers? There's now a case for that. The Canopy Sensus Touch Sensitive case for iPhone is the first case to feature capacitive touch capabilities built into the case itself, allowing you to interact with your iPhone by touching the sides and back of the case.

Canopy designed the Sensus to allow iPhone users to expand the functionality of their smartphone experience by adding touch-sensitive areas to the back and sides of the case. It's very similar to the touch-enabled back of the Sony PlayStation Vita and laptop touch pads allowing you to control the screen without obstructing its view. The Senus has touch sensors built into the back and right side of the case and can handle an accurate 10 points of input at once. It's perfect for controlling games and apps by touching your fingers to the back of the case and using the side area for scrolling through Web pages and other apps.

These features definitely add even more use to the multi-touch input found on the iPhone but in order to use these features, the apps need to be optimized for use with the Sensus. According to Canopy there are currently about 500 apps that support the Sensus' touch areas and the Senus app will show you which installed applications on your iPhone support the features. Canopy wants to make it clear to developers that it will only take a few minutes of coding to add the most basic features.

The Sensus case is being shown off by Canopy at the 2013 International CES (or CES 2013). The Senus case is currently being built for the iPhone 4, iPhone 4S and the iPhone 5, with versions for the iPod touch, iPad mini, and iPad in the works. The case is expected to ship this summer with a retail price between $59 and $99.
