LucidTouch – the see-through mobile device

March 7, 2008 Touch is a compelling input modality for interactive devices, but fingers get in the way on the small screen of a mobile device. Microsoft held its annual Techfest earlier this week, showing a range of new technologies certain to play a role in the future of mankind. One that jumped out at us was the LucidTouch, a mobile device that addresses this limitation by allowing the user to control the application by touching the back of the see-through device. The key to making the LucidTouch usable is pseudo-transparency: by overlaying an image of the user’s hands onto the screen, Microsoft has created the illusion of the mobile device itself being semitransparent, allowing users to accurately acquire targets while not obscuring the screen with their fingers and hand.
