Abstract: The present invention provides a system and methods for motion-based scrolling of a relatively large contents view on an electronic device with a relatively small screen display. The user controls the scrolling by changing the device's tilt relative to a baseline tilt. The scrolling control can follow a Proportional Scroll mode, where the relative tilt directly controls the screen position over the contents view, or a Dynamic Scroll mode where the relative tilt controls the scrolling speed. The present invention obtains a criterion for automatically selecting the best scrolling mode when the dimensions of the contents view change. The baseline tilt is updated when the screen reaches an edge of the contents view to eliminate the creation of a non responsive range of tilt changes when the user changes tilt direction.

Abstract: There is provided an image display device which is kept from wastefully consuming electric power while an eyelid is closed by blinks in a waking state. A signal from an FIR sensor (14) is inputted to a positive (+) terminal of a comparator (32) via an amplifier (31) while a threshold (Th) is inputted to a negative (?) terminal of the comparator (32). When an eyelid (1) is closed more than necessary to block all the field of view, a level of the signal inputted from the FIR sensor (14) to the positive (+) terminal of the comparator (32) is higher than the level of the threshold (Th). Thus, a high-level signal is outputted from the comparator (32) and a low-level signal is inputted to a driver (34) via an inverter (33), so that the driver (34) turns off a backlight (12).
