Patent ID: 7903929

Claim:
A portable electronic device, comprising: an optical display; a display controller for presenting display data to the optical display in order to display the display data; and an accelerometer operatively coupled to the display controller, wherein the display controller presents the display data to the optical display as a function of motion of the portable electronic device as sensed by the accelerometer, wherein the display data comprises a character string, and the display controller presents the display data to the optical display sequentially beginning at a first end of the character string when the accelerometer senses motion in a first direction, and beginning at a second end of the character string when the accelerometer senses motion in a second direction opposite the first direction and back and forth motion of the portable electronic device in the first and second directions results in repeated display of the character string and wherein the display controller keeps track of a position at which the display of the character string ended during a previous motion in order to determine a position at which to begin the display of the character string during the next motion in the back and forth motion if the character string is not displayed in its entirety from the first end to the second end in the previous motion.
