Japanese accessory maker Elecom announced [JP] the kandenchi today, a wireless mouse that’s designed like a battery. The 2.4GHz device, developed in cooperation with Tokyo-based design company nendo, can be connected to your computer via USB.
Technically, the kandenchi is really a conventional three-button mouse and compatible to Windows XP/Vista/7 and Mac OS X 10.5 and up.
Here’s how buyers would use the mouse (Elecom is using only promotion pictures that show people holding the mouse with the right hand, but I suppose this works for lefties, too):
Elecom plans to start selling the kandenchi in Japan in October for $65. Ask specialized online stores like Geek Stuff 4 U if you’re interested but live outside Japan.
