Disabling an automatic rotation function of mobile computing devices
View Patent ↗Technology is generally described for disabling an automatic rotation function of mobile computing devices. The technology can detect a tilt angle of a display of the computing device in relation to a surface; and if the tilt angle is less than a specified threshold tilt angle, disable a rotation function.
1. A system for detecting whether to disable a rotation function of a computing device having a processor, memory, and a display, comprising:
a sensor configured to detect a tilt angle of a display surface in relation to a plane; and
a component configured to disable a rotation function of the computing device if a difference between the tilt angle and a specified threshold tilt angle exceeds a specified value.
2. The system of claim 1 wherein the plane is perpendicular to a force of gravity.
3. The system of claim 1 wherein the sensor is an accelerometer.
4. The system of claim 1 wherein the sensor is a six-axis accelerometer.
5. The system of claim 1 wherein the plane is a surface on which a user views the display while the user is in a supine position.
6. The system of claim 1 further comprising a rotation switch that, if actuated, overrides the component configured to disable rotation.
7. The system of claim 1 further comprising means for computing the difference between the tilt angle and the specified threshold tilt angle.
8. The system of claim 1 further comprising means for disabling the rotation function.
9. The system of claim 1 wherein the sensor is a gyroscopic sensor.
10. The system of claim 1 wherein the sensor provides an indication of an angle between the plane and a direction of gravity.
