Abstract:
1. An apparatus for moving a display screen of a mobile computer device comprising: a first acceleration sensor for detecting a side-to-side movement and slant of the mobile computer device in the side-to-side direction; a second acceleration sensor for detecting an up-to-down movement and slant of the mobile computer device in the up-to down direction; a first A/D converter for converting analog signals produced by the first acceleration sensor into a first gravitational mode signal corresponding to the slant of the side-to-side direction of the mobile computer device and a first acceleration digital signal corresponding to the side-to-side movement of the mobile computer device, a second A/D converter for converting analog signals produced by the second acceleration sensor into a second gravitational mode signal corresponding to the slant of the up-to-down direction of the mobile computer device, and a second acceleration digital signal corresponding to the up-to-down movement of the mobile computer device; a first integrator and a third integrator for producing a first window-moving mode signal by successively integrating the first acceleration digital signal; a second integrator and a fourth integrator for producing a second window-moving mode signal by successively integrating the second acceleration digital signal; and a screen controller for receiving a first display signal including all information, and producing a second display signal including a part of information according to the first and the second gravitational mode signals or the first and the second window-moving mode signals.
