Wireless Pointing Mouse From JW Tech
JW Tech recently presented a very cool pointing mouse that could be really handy during multimedia class or presentations. It features both a wireless trackball mouse that takes advantage of the radio frequency technology, as well as laser pointing function. You can freely use it while moving around within 20m radius. To avoid the signal being jammed, 5 different frequencies are provided. One of the most unique feature is the receiver itself. Check out the picture below and you'd see that the receiver device is a wired 5-button optical mouse. So, instead of one, you'd get two functional mice in a bundle.
