Abstract
An information handling system totem input device maintains position on an articulating touchscreen display by selectively engaging friction members at the totem bottom surface with the touchscreen display surface. A capacitive sensor integrated in the totem senses end user touch and/or proximity to extend the friction members when an end user releases the totem. In one embodiment, the amount of extension and associated frictional resistance provided by the friction members adjusts based upon lateral acceleration sensed by accelerometers in the totem or in the display.
Claims20
An information handling system comprising:
- a processor operable to execute instructions that process information;
- a touchscreen display interfaced with the processor, the touchscreen display operable to detect touches and report the touches to the processor;
- an input device disposed on the touchscreen display and having a predetermined footprint detected as a touch by the touchscreen display and reported to the processor;
- a capacitive sensor integrated in the input device and operable to detect touches at the input device;
- and
- a friction member disposed at a bottom surface of the input device and interfaced with the capacitive sensor, the friction member retracting into the input device in response to touch detected by the capacitive sensor and extending out of the input device in response to predetermined conditions detected at the input device.
A method for managing totems disposed on an information handling system display, the method comprising:
- extending a friction member from a bottom surface of the totem against the display, the friction member engaging against the display to resist movement of the totem across the display;
- detecting an end user touch at the totem;
- and
- in response to detecting the touch, retracting the friction member into the totem.
An information handling system totem input device comprising:
- a body having a bottom surface that interacts with a touchscreen display to make touch inputs at the touchscreen display;
- one or more friction members disposed at the bottom surface and configured to selectively extend and retract, the one or more friction members when extended increasing frictional resistance to movement of the body against the touchscreen display;
- and
- a capacitive sensor integrated in the body and configured to measure capacitance at the body associated with end user touch, the capacitive sensor selectively extending and retracting the one or more friction members based at least in part on measured capacitance.
