A computer that reads hand signals
Yes a computer that reads hand signals! I don't know how many, but I imagine, just like voice control, once you learn the hand signals, access is easy. Toshiba has developed the Qosmio G55-Q802 using the same chip that is found in Playstation 3. Along with Toshiba’s hand-gesture and video-indexing applications, the laptop comes with ultrafast Cell-enabled versions of Microsoft’s PowerPoint and Corel’s Ulead video-editing program. I think the potential for computers users who struggle with fine motor access is incredible. Go to this site to read a brief report about the computer with sample hand signals:
