Whereas the iFeel used Immersion TouchSense technology, the AVB mouse takes output from your soundcard via a little device that goes between your headphone jack and audio output socket. The mouse then picks up any and all sounds from your machine and translates them into mouse vibrations. The main benefit of this solution is that it works on absolutely any operating system you´d care to think of: Windows, Linux, Mac OS, BSD, BeOS, Unix I could go on, but basically, if you are running an OS that supports PS/2 mice, the VMouse will be fully functional without the need for any special software.
