Canopy's Sensus iPhone case (via Engadget) is touch-enabled, with 10 different touch input points across the back and the right side of the case. The touch input allows for users to interact with apps without blocking the screen with a finger, a useful function for iOS gaming. It is similar in design to the rear trackpad of Sony's PlayStation Vita.
The Sensus, which resembles a slightly thicker than average iPhone case, has integrated apps that are designed for the visually impaired, along with Braille entry on its touch panels. The company is working on additional apps and has released a software development kit for developers.
It is constructed from durable polycarbonate with rubber corners to protect the iPhone from bumps and falls. It comes equipped with a built-in processor that monitors touch input, and it is powered through the charging port of the iPhone.
At this point in time there is only a version for the iPhone 4/4S on display at CES, but the company is working on a version for Apple's iPhone 5.
Canopy's Sensus case will be available during the Summer of 2013, at a cost between $59 and $99.
