Abstract

Provided are a method for configuring a three-dimensional (3D) input device, a method for reconfiguring the 3D input device, a method for recognizing wearing of the 3D input device, and an apparatus for the same. The method of configuring a three-dimensional (3D) input device, which performs information input operations using a finger device that is worn by a user and senses the user'"'"'s finger movement, includes recognizing whether the user is wearing the finger device and recognizing the finger positions of the device, and adaptively configuring the 3D input device based on the recognition results. Thus, it is possible to implement a user-friendly 3D input device by automatically or manually configuring the 3D input device.

adaptively configuring a signal-processing unit, which processes movement signals sensed by the finger device, based on the recognition results; and

adaptively configuring a device driver of the 3D input device based on the recognition results and basic set-up information used for information input.

3. The method of claim 2, wherein the basic set-up information includes input scenario information related to arrangement of information items that are selected by finger movement and a language used for information input.

4. The method of claim 2, wherein the application configures a soft keyboard based on the recognition results and the basic set-up information, when the application receives the recognition results and the basic set-up information from the device driver.

5. The method of claim 4, wherein the application outputs the configured soft keyboard to an output device.

6. The method of claim 5, wherein the soft keyboard displays finger positions of the finger device on an array of information items that are selected by finger movements.

7. A method of reconfiguring a three-dimensional (3D) information input device, which inputs information by using a finger device that is worn by a user and senses the user'"'"'s finger movement, the method comprising:

receiving reset information, used for reconfiguration of the 3D information input device, from a user through a user interface; and

reconfiguring a device driver of the 3D input device based on the received reset information.

8. The method of claim 7, wherein the reset information includes information about permission or cancel of use on a specific finger of the finger device, information about selection of an input scenario related to arrangement of information items that are selected by finger movement, and information about selection of the language used for information input.

9. The method of claim 7, wherein the user interface uses a control board of a Window system.

10. A method of recognizing whether a user is wearing a three-dimensional (3D) input device, which includes a finger device with a plurality of sensors attached thereto that sense finger movement and input information based on finger movement signals sensed by the sensors, the method comprises:

(a) acquiring sensor signals, which are used to sense movement of the finger device;

(b) determining, from the acquired sensor signals, whether at least the predetermined number of edges are detected; and

(c) recognizing whether the user is wearing the 3D input device based on the results of step (b).

11. The method of claim 10, wherein step (a) further comprises:

(a1) storing information about sensors experiencing changes between current sensor signal values and previous sensor signal values, and timer values at the time when the changes occur.

determining whether at least the predetermined number of timer values are detected.

13. The method of claim 12, wherein step (c) further comprises:

if at least the predetermined number of timer values are detected, recognizing that the user is wearing the finger device with corresponding sensors outputting the acquired sensor signals attached thereto; and

unless at least the predetermined number of timer values are detected, recognizing that the user is not wearing the finger device with corresponding sensors outputting the acquired sensor signal.

14. The method of claim 13, wherein the method further comprises:

(d) if it is recognized that the user is not wearing the finger device, outputting information indicating an error value; and

(e) if it is recognized that the user is wearing the finger device, calculating duty ratios by using the timer values, scaling the calculated duty ratios by a predetermined value and outputting the scaled values.

15. A three-dimensional (3D) input device, which is adaptively configurable and performs information input operation using a finger device that is worn by a user and senses the user'"'"'s finger movement, the 3D input device comprising:
