Abstract

This invention describes a method for a new methodology for double-phase keys used to minimize pressing-key errors in electronic devices (e.g., portable communication devices, mobile phones, etc.). During the first phase, the key is pressed, e.g., half-way without actually sending the information to an active application. When the user presses the key half-way, the operating system of the electronic device provides to the user an audio feedback about the identity of the pressed key. The user can then either move the finger from the key (if it is not an intended key) or press the key all the way down (if it is the intended key). When the key is pressed down fully (the second phase), the appropriate active application actually receives the intended message/command (e.g., a number/character used in the active application) and the electronic device provides to the user an audio feedback confirmation of the fully-pressed key.

providing a half-way feedback signal describing an identity of said one key by said electronic device to the user in response to said half-way pressing; and

pressing full-way said one key by the user to communicate said predetermined message/command to said electronic device only if said identity of said one key corresponds to said one key, thus minimizing pressing-key errors by using said double-phase key approach.

2. The method of claim 1, wherein said half-way feedback signal is a speech feedback signal containing an audio identity of said one key.

3. The method of claim 1, wherein after the step of said pressing half-way, the method comprises the steps of:

generating a half-way key actuating signal by said user interface module, optionally using a touch actuator of said user interface module in response to said pressing half-way of said one key; and

generating a half-way key signal containing said identity of said one key by an actuation controller of said electronic device in response to said half-way key actuating signal.

4. The method of claim 3, wherein said half-way feedback signal is generated by a half-way feedback block of said electronic device in response to said half-way key signal, and optionally said half-way feedback signal is a speech feedback signal containing an audio identity of said one key.

5. The method of claim 1, wherein after the step of said pressing full-way, the method comprises the steps of:

generating a full-way key actuating signal containing said predetermined message/command by a user interface module, optionally using a touch actuator of said user interface module, in response to said pressing full-way of said one key; and

generating a full-way key signal by an actuation controller in response to said full-way key actuating signal.

6. The method of claim 5, further comprises the steps of:

generating, by a full-way feedback block of the electronic device, a full-way feedback signal, containing a confirmation of communicating said predetermined message/command to said electronic device, in response to said full-way key signal and providing said full-way feedback signal to the user.

7. The method of claim 6, wherein said full-way feedback signal.

8. The method of claim 1, wherein said user interface module contains a touch-device or a touch-screen, optionally providing a tactile feedback to the user when said one key is pressed full-way.

9. The method of claim 1, wherein said pressing half-way is implemented as a single click and said pressing full-way is implemented as a double click or said pressing half-way is implemented as the double click and said pressing full-way is implemented as the single click.

10. The method of claim 1, wherein said pressing half-way is implemented as a short click and said pressing full-way is implemented as a long click or said pressing half-way is implemented as the long click and said pressing full-way is implemented as the short click.

11. The method of claim 1, wherein said electronic device is a wireless device, a portable device, a mobile communication device or a mobile phone.

12. A computer program product comprising:

a computer readable storage structure embodying computer program code thereon for execution by a computer processor with said computer program code characterized in that it includes instructions for performing the steps of the method of claim 1 indicated as being performed by any component or a combination of components of said electronic device.

13. An electronic device capable of using a double-phase key approach to minimize pressing-key errors, comprising:

a user interface module with N keys, responsive to pressing half-way one key of said N keys with an intent to communicate a predetermined message/command to said electronic device by a user of said electronic device and responsive to pressing full-way said one key by said user to communicate said predetermined message/command to said electronic device, wherein N is an integer of at least a value of two; and

means for providing a half-way feedback signal describing an identity of said one key by said electronic device in response to said half-way pressing to the user,

wherein said pressing full-way said one key by the user occurs only if said identity of said one key corresponds to said one key, thus minimizing pressing-key errors by using said double-phase key approach.
