Patent ID: 8274484

Claim:
A device comprising: a display screen disposed on a first side of the device; a screen-reflective interface disposed on a second side of the device opposite the first side; at least one processor; and processor-executable instructions that configure the device to: monitor the screen-reflective interface; detect a touch input comprising a user touch contact with the screen-reflective interface; activate a tracking state for the screen-reflective interface responsive to the detected touch input on the screen-reflective interface; display a first interface icon on the display screen to indicate that the tracking state has been activated, the first interface icon displayed at a location of the display screen that corresponds to a position of the touch input on the screen-reflective interface; detect a press input comprising a user press contact with the screen-reflective interface while the tracking state is activated, the user press contact being different than the user touch contact; activate an engaged state for the screen-reflective interface responsive to the detected press input at the screen-reflective interface, wherein the engaged state comprises initiating at least one distinct interaction functionality that visually distinguishes the press input from the touch input by replacing, in response to the user press contact with the screen-reflective interface, the first interface icon with a second interface icon that is different than the first interface icon and is displayed on the display screen at a location that corresponds to a position of the press input on the screen-reflective interface.
