This patent from XM certainly has interesting implications for touch based Ultra-Mobile PCs and Tablet PCs. Imagine being able to use different fingers for various short-cuts, like a thumb to launch Windows Media Player, the pinky to launch email, etc. Take that a bit further and imagine the UMPC finger experience being custom for each person using it. My thumb can launch Media Player while my wife’s thumb would launch OneNote.
Well, if XM’s patent has any validity and the technology spreads to other devices besides their satellite radio systems, it could certainly make for some interesting experiences.
