Genius has announced the release of its Wireless Thumb Cursor Controller, or ring mouse for short. The clicking and scrolling action of the lightweight mouse replacement is thumb-controlled, its proprietary optical touch technology offers users 1000 dpi sensitivity and it's said to last a month between charges.
The 1.15 x 1.32 x 1.25-inch (29.3 x 33.7 x 32 mm), 0.42 ounce (12 g) Ring Mouse has 2.4GHz wireless connectivity with a range of around 30 feet (10 meters), and links to a USB nano/pico receiver slotted into a spare port on a Windows-based computer or laptop. Worn on the index finger, left and right click and optical touch control tracking technology are set around the top for thumb control of an onscreen cursor.
Although its primary use is likely to be controlling a projected presentation or photo slideshow, it should also prove useful as a travel laptop mouse, for those who regularly find themselves having to work in cramped conditions, or for those who just don't like to use a trackpad. The tracking sensitivity might also make it useful for mobile gamers.
