Ring mouse - no limitation

Simply wear it on any finger (according to your comfort) and move it on just about any surface and the mouse will do its job to control the on-screen cursor, just like any ordinary mouse. This nifty gadget is truly good news for those who suffer wrist injury because of using the regular mouse. At Computex in Taipei, Global Link is showing off a "Ring Mouse" which straps to your finger and allows you to use it on any surface, including your thumb. There are no specific details on how the Ring Mouse actually works but I presume it have a built-in optical sensor like the usual optical mouse.
