Meet ThumbTrack: one of the smallest mice you will ever see. It has an ergonomic design and lets you control your apps by the tip of your thumb. You will be able to perform all mouse functions with ease without putting any stress on your hand and wrist. With a ThumbTrack at your disposal, you will be able to maintain a comfortable body posture while working on your computer.
ThumbTrack does everything a traditional mouse does and more. You can press the center button for 3 seconds to turn it on, slide your thumb over the main tracking area to navigate, and use its buttons to select. Capacitive touch-scrolling is also available. This interesting mouse is on Indiegogo.
