4. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to determine a position of the keyboard relative to a user, in part, by identifying a current posture of the IHS as a tablet posture, wherein: a first display surface of the first display is placed facing up, and a back surface of the first display is placed against a back surface of the second display.
5. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to determine a position of the keyboard relative to a user, in part, by identifying a current posture of the IHS, wherein: the first display is placed at an acute angle with respect to the second display.
6. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to determine a position of the keyboard relative to a user, in part, by identifying a current posture of the IHS as a tent posture, wherein: a first display surface of the first display is placed at an obtuse angle with respect to a second display surface of the second display.
7. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to, in response to the determination, resize an application on the second display, or move the application from the second display to the first display.
8. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to, in response to the determination, provide a virtual touchpad on a rectangular portion of the display surface below the keyboard.
9. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to, in response to the determination, turn off touch input in an area of the second display under the keyboard.
10. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to, in response to the determination, provide a touch bar on the second display along the keyboard.
11. The IHS of claim 10 , wherein the program instructions, upon execution, further cause the IHS to: determine that the keyboard is being moved from a higher position on the display surface to a lower position on the display surface; and provide an additional touch bar.
12. The IHS of claim 11 , wherein the program instructions, upon execution, further cause the IHS to: determine that the keyboard is being moved from a lower position on the display surface to a higher position on the display surface; and remove the additional touch bar.
13. A method, comprising:
detecting a keyboard using a magnetic sensor, wherein: (a) the magnetic sensor comprises a single Hall effect sensor and the keyboard comprises at least one magnet with variable Gauss values along a magnet's axis; (b) the magnetic sensor comprises a plurality of Hall effect sensors and the keyboard comprises a plurality of magnets in fixed locations, (c) the magnetic sensor comprises a 3-Dimensional (3D) Hall effect sensor and the keyboard comprises a programmed magnet, or (d) the magnetic sensor comprises a magnetometer and the keyboard comprises a single magnet in a fixed location; and
determining, in response to the detection, a position of the keyboard relative to a display surface of a second display, wherein the second display is coupled to a first display via a hinge.
14. The method of claim 13 , wherein further comprising determining a position of the keyboard relative to a user, in part, by identifying a current posture of the IHS as a laptop posture, wherein: the first display is placed at an obtuse angle with respect to the second display, and the second display is placed in a horizontal position with a display surface facing up.
15. The method of claim 13 , further comprising determining a position of the keyboard relative to a user, in part, by identifying a current posture of the IHS as a tablet posture, wherein: a first display surface of the first display is placed facing up, and a back surface of the first display is placed against a back surface of the second display.
16. The method of claim 13 , further comprising determining a position of the keyboard relative to a user, in part, by identifying a current posture of the IHS as a canvas posture, wherein: the first display is placed at a straight angle with respect to the second display, and the first and second displays are placed in a horizontal position with first and second display surfaces facing up.
17. A hardware memory device having program instructions stored thereon that, upon execution by a processor of an Information Handling System (IHS), cause the IHS to:
detect a keyboard using a magnetic sensor, wherein: (a) the magnetic sensor comprises a single Hall effect sensor and the keyboard comprises at least one magnet with variable Gauss values along a magnet's axis; (b) the magnetic sensor comprises a plurality of Hall effect sensors and the keyboard comprises a plurality of magnets in fixed locations, (c) the magnetic sensor comprises a 3-Dimensional (3D) Hall effect sensor and the keyboard comprises a programmed magnet, or (d) the magnetic sensor comprises a magnetometer and the keyboard comprises a single magnet in a fixed location; and
