Display screen orientation lock removed by the angle between the display screen and the keyboard or bottom of the computing device exceeding a predetermined angle

摘要

A computer system comprising that has a display screen that displays information from a computing device. An auxiliary device such as a cover or a keyboard is pivotally attached to the display screen. When the angle between the display screen and the auxiliary device is a first angle that makes it likely that the device is being used normally, the device is then locked against orientation rotation. The angle between the auxiliary device and the display needs to be brought into an unnatural angle in order to allow automatic orientation rotation.

主权项

1. A computer system comprising:
a display screen; a computing device, that produces output to be displayed on the display screen; an auxiliary device for the computing device, attached to the display screen, and pivotable relative to the display screen; and an angle sensor, sensing an angle between the auxiliary device and the display screen, and producing a signal indicative of said angle and coupling said signal to said computing device, wherein said computing device detects a first angle and locks an orientation that is displayed on the display screen to a locked orientation based on detecting said first angle between said computing device and said auxiliary device, where said first angle is an angle which would normally exist between said computing device and said auxiliary device when said auxiliary device was being used by a user to enter data onto the computing device, and said computing device detects a second angle between said computing device and said auxiliary device, where said second angle is an angle that would normally not exist when the user was entering data into said auxiliary device on said computer, and unlocks the orientation that is displayed on the display screen to an unlocked orientation based on detecting said second angle, where in said locked orientation, a display on said display screen cannot be rotated, and in said unlocked orientation, the display on said display screen can be rotated.
