Stylus activated display/key-lock
View Patent ↗A device may include an instrument-enabled user interface. The device may also include a switch to at least partially enable operations associated with user input via the user interface. Triggering of the switch may be based on a relative positioning of the instrument.
1. A mobile communication device comprising:
a housing including a stylus retainer;
a user input device including a touchscreen-enabled display;
a stylus to be received within the stylus retainer, and to interface with the user input device via contact with the touchscreen-enabled display; and
logic to:
permit interfacing with the user input device, via contact of the touchscreen-enabled display, for a predetermined amount of time following placement of the stylus in a first position within the stylus retainer;
prevent, following the predetermined amount of time, interfacing with the user input device, via contact of the touchscreen-enabled display, when the stylus is in the first position within the stylus retainer; and
permit interfacing with the user input device, via the contact of the touchscreen-enabled display, when the stylus is in a second position within the stylus retainer, where a first trigger point within the stylus retainer for transitioning from a first state, of prevented interface with the user input device, to a second state, of permitted interface with the user input device, differs from a second trigger point within the stylus retainer for transitioning from the second state to the first state.
2. The mobile communication device of claim 1 , where the logic is to permit the interfacing with the user input device when the stylus is displaced from the first position, by a particular amount, to the second position.
3. The mobile communication device of claim 1 , further comprising a keypad, where the keypad is operable when the stylus is in the first position.
4. The mobile communication device of claim 1 , further comprising:
a switch to permit the interfacing with the user input device regardless of whether the stylus is in the first position.
5. The mobile communication device of claim 1 , where the touchscreen-enabled display comprises at least one of a pressure-sensitive display, an acoustically-sensitive display, an electrically-sensitive display, or a photo-sensitive display.
6. The mobile communication device of claim 1 , where the logic is further to permit the interfacing with the user input device based on at least one of an amount of time the stylus is in the second position or an amount of time since the stylus has been used with the user input device.
7. The mobile communication device of claim 1 , where the stylus retainer comprises a slot, and the first trigger point is at an insertion depth within the slot that is less than an insertion depth within the slot for the second trigger points.
8. The mobile communication device of claim 7 , where when the stylus is at an insertion depth within the slot that is between the first and second trigger point, the logic is to maintain the first state or the second state.
