Abstract

According to one embodiment, an input control module determines, responding to release of a contact state of one of a plurality of first positions on a touch-screen display, which are put in contact with external objects, whether a contact time from when the external object is put in contact with the one of the plurality of first positions to when the contact state of the one of the plurality of first positions is released is shorter than a threshold time. The input control module executes an input process of inputting a key code associated with one of a plurality of first keys which corresponds to the one of the first positions, when the contact time is shorter than the threshold time.

Claims

1. An electronic apparatus comprising:

a touch-screen display;

a keyboard display module configured to display on the touch-screen display a virtual keyboard comprising a plurality of keys; and

a controller configured to input a key code in accordance with a user operation on the virtual keyboard,

the controller comprising;

a detection module configured to detect a plurality of first keys among the plurality of keys in response to contact between a plurality of first positions on the touch-screen display and an external object, the plurality of first keys corresponding to the plurality of first positions; and

an input control module configured to;

determine whether a contact time from when the external object contacts one of the plurality of first positions to when the external object releases contact with the one of the plurality of first positions is shorter than a threshold time,

when the contact time is shorter than the threshold time, execute an input process for a key code associated with one of the plurality of first keys corresponding to the one of the plurality of first positions, and

when the contact time is not shorter than the threshold time, skip execution of the input process.

2. The electronic apparatus of claim 1,

wherein the plurality of keys include two specific keys for discriminating a home key position, and

wherein the electronic apparatus further comprises a first feedback module configured to generate a notification indicating that the external object contacted a position corresponding to the home key position when the one of the plurality of first keys is one of the two specific keys.

3. The electronic apparatus of claim 2, further comprising a second feedback control module configured to generate a notification indicating that the input process has been executed.

4. The electronic apparatus of claim 3, wherein the second feedback control module is configured to generate a notification indicating that the input process has been skipped.

5. The electronic apparatus of claim 1, further comprising a sensor configured to detect an impact degree of an impact applied to the electronic apparatus,

wherein the input control module is configured to further determine whether the impact degree detected by the sensor is greater than a first threshold value, and configured to skip execution of the input process when the impact degree detected is less than the first threshold value.

6. The electronic apparatus of claim 1, wherein the input control module is configured to further determine whether a contact pressure between the one of the plurality of first positions and the external object is greater than a second threshold value, and configured to skip execution of the input process when the contact pressure is less than the second threshold value.

7. The electronic apparatus of claim 1, further comprising:

a communication module configured to communicate with an external device; and

a key code transmission module configured to transmit the key code to the external device via the communication module.

8. The electronic apparatus of claim 1, further comprising a mode switching module configured to determine whether a distance between two contact positions by the external object on the touch-screen display is shorter than a threshold distance, and configured to switch, when the distance between the two contact positions is shorter than the threshold distance, an operation mode of the input control module from a virtual keyboard input mode for inputting a key code in accordance with a user operation on the virtual keyboard to a mouse input mode for inputting relative coordinate data which is indicative of a direction and distance of movement of a contact position in accordance with movement of the contact position on the touch-screen display, the contact position being a position touched by the external object.

9. The electronic apparatus of claim 1, further comprising a feedback control module configured to generate a notification indicating that the input process has been executed.

10. The electronic apparatus of claim 9, wherein the feedback control module is configured to generate a notification indicating that the input process has been skipped.

11. The electronic apparatus of claim 5, wherein the input control module is configured to further determine whether a contact pressure between the one of the plurality of first positions and the external object is greater than a second threshold value, and configured to skip execution of the input process when the contact pressure is less than the second threshold value.

12. An input method for an electronic apparatus comprising a touch-screen display, comprising:

displaying on the touch-screen display a virtual keyboard comprising a plurality of keys;

detecting a plurality of first keys among the plurality of keys in response to contact between a plurality of first positions on the touch-screen display and an external object, the plurality of first keys corresponding to the plurality of first positions;

determining whether a contact time from when the external object contacts one of the plurality of first positions to when the external object releases contact with the one of the plurality of first positions is shorter than a threshold time, in response to the external object releasing contact with the one of the plurality of first positions, and

when the contact time is shorter than the threshold time, executing an input process of inputting a key code associated with one of the plurality of first keys corresponding to the one of the plurality of first positions; and

when the contact time is not shorter than the threshold time, skipping execution of the input process.

13. A computer-readable, non-transitory storage medium having stored thereon a program, the program causing a computer comprising a touch-screen display to:

display on the touch-screen display a virtual keyboard comprising a plurality of keys;

detect a plurality of first keys among the plurality of keys in response to contact between a plurality of first positions on the touch-screen display and an external object, the plurality of first keys corresponding to the plurality of first positions;

determine whether a contact time from when the external object contacts one of the plurality of first positions to when the external device releases contact with the one of the plurality of first positions is shorter than a threshold time;

when the contact time is shorter than the threshold time, execute an input process for a key code associated with one of the plurality of first keys corresponding to the one of the plurality of first positions; and

when the contact time is not shorter than the threshold time, skip execution of the input process.
