A company called Spicebox is showing at CES a hardware-software product called Mauz that turns your iPhone into a mouse that can also read motion gestures through the camera.
The product comes in three parts: a snap-on thing for your iPhone, an app for your iPhone and a driver for your Mac.
Mauz connects with your Mac over WiFi. It works like a regular mouse. But it can also register movement of the phone like the Nintendo Wii remote, as well as register in-air gestures like the Microsoft Kinect for Xbox 360. Here’s a video.
The product should sell for less than $70 when it becomes available in June.
