The Mouse Ring
|This is the wireless mouse that slips onto a forefinger like a ring for easy control of a computer’s functions during presentations. In addition to “left” and “right” mouse buttons, its thumb touch pad uses a patented optical sensor with 1,000-dpi sensitivity, providing eight-way scrolling. It communicates from up to 30′ away over an interference-free 2.4 GHz radio frequency with a receiver that plugs into a computer’s USB port.
