Patent ID: 8334837

Claim:
A method comprising: causing projection of a virtual interaction unit comprising a plurality of interaction areas configured for activation by an activation unit onto a surface located adjacent to a device; detecting an approached interaction area of said virtual interaction unit, wherein said approached interaction area is one of said plurality of interaction areas that is approached by said activation unit without yet being activated; detecting an activated interaction area, wherein said activated interaction area is one of said plurality of interaction areas activated by said activation unit, causing display of a first representation of said approached interaction area in response to said activation unit approaching said approached interaction area on a display of said device in a first representation mode only when an interaction with said device is required, and causing display of a second representation of said activated interaction area in response to activation of said activated interaction area by said activation unit on said display in a second representation mode, wherein said second representation of said activated interaction area is displayed until said activation unit is removed from said activated interaction area, wherein said second representation is configured for display at the same location on said display as said first representation when said approached interaction area and said activated interaction area are the same interaction area of said plurality of interaction areas, and wherein of said plurality of interaction areas only representations of approached interaction areas and activated interaction areas are displayed in real-time on said display, and said representations of approached and activated interaction areas are simultaneously displayed on said display.
