Abstract: A method and system for enabling interaction between a user and an electronic device includes sensing at least one of position and movement of at least one finger on a physical keyboard, determining position of the finger on the physical keyboard and emulating at least one of a virtual mouse, a virtual touch screen, a virtual hand on a display, and a gesture sensing technique to enable the interaction in accordance to at least one of the position and the movement of the finger. The system includes an electronic device, a communication interface, a memory and a processor.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for controlling a display device that includes a first display, a touch screen disposed on the first display and a second display. In one aspect, the first display may be disposed on a first side of the display device (e.g., the front side) and the second display may be disposed on a second side of the display device (e.g., the back side). The second display may consume less power than the first display. Even when the first display is switched off, a control system may be configured to control the second display in response to input received from the touch screen disposed on the first display. The control system may be further configured to control the first display in response to input received from the touch screen when the first display is switched on or when the second display is not in use.

Abstract: A method of writing a display image to a display having an array of pixels according to a selected driving sequence. One driving sequence includes addressing each color row in a line of the array in a sequence before addressing a second line. Another driving sequence includes addressing a first color row of each line in the array before addressing a second color row of each line in the array.
