Portable information handling system user interface selection based on keyboard configuration
A portable information handling system user interface adapts based upon a position of a keyboard, such as a position detected by accelerations, Hall sensors, ambient light sensors and/or touchscreen display touches. In one example embodiment, a visual indication presented at a display aids end user location of a keyboard in a hidden position, such as a sliding keyboard disposed under a housing portion or a membrane keyboard integrated in a housing portion lower surface and exposed by a disconnect and flip motion.
1. A method for information handling system keyboard detection, the method comprising:
disposing a first display portion over a first side of a first housing portion;
disposing a second display portion over a first side of a second housing portion;
rotationally coupling the first and second housing portions to each other;
coupling a keyboard to the second side of the second housing portion;
sensing accelerations associated with the first housing portion, the second housing portion and the keyboard; and
detecting a transition of the keyboard between hidden and exposed positions by comparing the accelerations;
detecting a perpendicular acceleration vector between the keyboard and the first housing portion;
confirming the transition with ambient light sensors disposed in the first housing portion and second housing portion;
separating the first and second housing portions from each other at the hinge; and
flipping the orientation of the second housing portion relative to the first housing portion to expose the keyboard.
2. The method of claim 1 wherein the detecting a transition further comprises:
detecting a perpendicular acceleration vector between the keyboard and the first housing portion; and
confirming the transition with a Hall sensor disposed between the keyboard and the second housing portion.
3. The method of claim 1 further comprising:
turning off presentation of visual images at the second display portion; and
presenting stacked icons at the first display portion representing visual images turned off from the second display portion.
4. A method for information handling system keyboard detection, the method comprising:
disposing a first display portion over a first side of a first housing portion;
disposing a second display portion over a first side of a second housing portion;
rotationally coupling the first and second housing portions to each other;
coupling a keyboard to the second side of the second housing portion;
sensing accelerations associated with the first housing portion, the second housing portion and the keyboard; and
detecting a transition of the keyboard between hidden and exposed positions by comparing the accelerations;
sensing a keyboard hidden position with a Hall sensor disposed between the second housing portion and keyboard;
presenting at the second display portion an indicator of the keyboard position;
de-coupling the keyboard from the second housing portion;
coupling the keyboard to a second side of the first housing portion in a hidden position; and
presenting at the first display portion an indicator of the keyboard position.
5. The method of claim 4 further comprising:
sensing movement of the keyboard from the hidden position to an exposed position; and
in response to the sensing, removing the indicator of the keyboard position.
