from MIT’s Technology Review:
The prototype for Manual Deskterity is a drafting application built for the Microsoft Surface, a tabletop touchscreen.
The interface’s most interesting features come out when the two types of interaction are combined. For example, a user can copy an object by holding it with one hand and then dragging the pen across the image, “peeling” off a new image that can be placed elsewhere on the screen. By combining pen and hand, users get access to features such as an exacto knife, a rubber stamp, and brush painting.
