Method for intermediate unlocking of a keypad on a mobile electronic device
First Claim
1. A method of changing the input states of an electronic device, having an input portion, the device capable of carrying out user operations, and the device having input states including a locked state, wherein the use of the input portion is significantly restricted, and an unlocked state, wherein the use of the input portion is not restricted comprising:
- entering the locked state by a locking input,entering the unlocked state by an unlocking input,entering an intermediate unlocked state of said electronic device, in which a limited operational use of said input portion is possible, from the locked state, based on an intermediate unlocking user input which is different from the unlocking input required for entering the unlocked state;
detecting the termination of a user operation in said intermediate unlocked state, the user operation being other than said locking input and including the completion of at least one task by a number of input operations greater than one; and
entering said locked state, in response to said detection.

Abstract
A method and device for changing input states of an electronic device, the device comprising an input portion and being capable of carrying out user operations, the input states comprising a locked state, where the use of the input portion is significantly restricted, and an unlocked state, where the use of the input portion is not restricted, the locked and unlocked states being respectively enterable by a locking and unlocking input. A further input state is an intermediate unlocked state in which a limited operational use of the input portion is possible; which method comprises entering the intermediate unlocked state from the locked state, based on user input; detecting termination of a user operation in the intermediate unlocked state, and entering the locked state, in response thereto. There is also provided an input controller, a keypad and a mobile electronic device implementing these features.

3. A mobile electronic device comprising:
-
an input portion; different user input states, the input states including a locked state, where the use of the input portion is significantly restricted, said locked state being enterable by a locking input, and an unlocked state, where the use of the input portion is not restricted, said unlocked state being enterable by an unlocking input, an intermediate unlocked state in which a limited operational use of said input portion is possible, wherein the electronic device is adapted to enter the intermediate unlocked state based on an intermediate unlocking user input which is different from the unlocking input required for entering the unlocked state; adapted to detect the termination of a user operation in said intermediate unlocked state, the user operation being other than said locking input and including the completion of at least one task by a number of input operations greater than one; and adapted to enter said locked state in response to said detection. - View Dependent Claims (4, 5, 6)

7. A mobile electronic device comprising:
-
means for user input; means for providing different user input states, the input states including a locked state, where the use of the means for user input is significantly restricted, said locked state being enterable by a locking input, and an unlocked state, where the use of the means for user input is not restricted, said unlocked state being enterable by an unlocking input, and an intermediate unlocked state in which a limited operational use of said means for user input is possible, means for entering the intermediate unlocked state based on an intermediate unlocking user input which is different from the unlocking input required for entering the unlocked state; means for detecting the termination of a user operation in said intermediate unlocked state, the user operation being other than said locking input and including the completion of at least one task by a number of input operations greater than one; and means for entering said locked state in response to said detection.
