Microsoft will be holding their annual research TechFest today and tomorrow. It is a chance for Microsoft's researchers to demo some of the ideas and innovations which have been brewing in their labs, ideas such as an interaction technique for use with small device called "LucidTouch."
iPhone users sometimes may have wished they had "transparent" fingers for their multi-touch actions. LucidTouch technology allows small screen interactions to be accomplished without covering up the content on display. This illusion is achieved with some clever use of software and camera in the back of the device. Check out Microsoft's LucidTouch and other TechFest demos here. - Wan Chi Lau
