Abstract

A user input apparatus is provided with user input means for the user to input data or a command by using the user'"'"'s human body, and use-form detection means for detecting a form in which the user uses the user input means by the user'"'"'s human body. A computer connected to the user input apparatus changes the operation of the application being executed by application execution means, according to a detection result obtained by the use-form detection means. Therefore, input operations can be performed without inconvenience even if the user cannot use one hand due to another work.

Claims

1. A user input apparatus, comprising:

a user input area including;

a plurality of first electrodes arranged along a first direction and continuously extending along a second direction different than the first direction; and

a plurality of second electrodes arranged along the second direction and continuously extending along the first direction;

a transmitter connected to the first electrodes and configured to supply first alternating signals to at least some of the first electrodes sequentially in a scanning manner;

a receiver connected to the second electrodes and configured to receive a second alternating signal from at least one of the second electrodes; and

use-form detection means configured to determine a distance between an object and an intersection of a scanned first electrode that is connected to the transmitter and the at least one of the second electrodes that is connected to the receiver based on changes in the second alternating signal received by the receiver.

2. The user input apparatus according to claim 1, further comprising:

a keyboard; and

a mouse,

wherein the use-form detection means determines whether a user operates the user input apparatus in a first use mode or a second use mode, the first use mode including a situation in which the user operates the keyboard by both a first hand and a second hand, and the second use mode including a situation in which the user operates the mouse by the first hand and operates the keyboard by the second hand.

3. The user input apparatus according to claim 1, wherein the use-form detection means determines whether a user operates the user input apparatus in an other-terminal use mode, the other-terminal use mode including a situation in which the user with at least one hand is operating a portable telephone or an other information terminal by the at least one hand.

4. The user input apparatus according to claim 1, further comprising:

a keyboard;

a transmission electrode disposed at a center of the keyboard;

a first receiving electrode at a left end of the keyboard; and

a second receiving electrode at a right end of the keyboard,

wherein the receiver further comprises;

a first receiver for receiving an alternating signal flowing through the first receiving electrode; and

a second receiver for receiving an alternating signal flowing through the second receiving electrode.

5. The user input apparatus according to claim 1, further comprising:

a mouse;

a transmission electrode at one end of the mouse; and

a receiving electrode at another end of the mouse.
