Remember ThumbTrack? It was a pretty small, wearable mouse. The second version of ThumbTrack is already here though. It is an ergonomic, ring shaped mouse that replaces your existing mouse and lets you use thumb movements to do things. The device has a battery that lasts up to 15 hours. There is no software to install. Just plug-in the dongle, and you are set.
The device has a USB nano dongle that acts like a wireless receiver. It has a range of up to 9 feet. ThumbTrack lets you work while maintaining a more comfortable body posture. It is compatible with Mac, Windows, and Linux computers. The project is on Indiegogo.
