Abstract

An information processing apparatus comprises a key and a proximity sensor. When the user places a finger on a depressing portion of the key, the proximity sensor detects the event, and inputs, to the information processing apparatus, proximity information indicating that the user'"'"'s finger is in proximity to the key. Based on the proximity information which has been input, the information processing apparatus displays information relating to the function assigned to the key. When the depressing portion is depressed with the user'"'"'s finger, the key inputs, to the information processing apparatus, information indicating that its contacts are in an on-state. Based on the input information, the information processing apparatus is able to execute the function. Thus, a function assigned to a physical key may easily be recognized by a user.

Claims

1. An information processing apparatus comprising:

first input means for detecting an input based on physical contact by a live body;

second input means for detecting an input based on the proximity of said live body to said first input means and comprising a plurality of line-shaped transmission electrodes;

an oscillator for providing each of said plurality of transmission electrodes with an alternating current for transmission;

a plurality of line-shaped reception electrodes disposed so as not to be in contact with said plurality of transmission electrodes; and

a receiver for receiving the alternating currents flowing through said plurality of reception electrodes;

wherein said transmission electrodes and said reception electrodes are disposed so as to cross each other; and

state identifying means for identifying a first state, where said live body is in proximity to said first input means, when the input based on the proximity of said live body to said first input means is detected by said second input means, and identifying a second state, where said first input means is operated, when the input based on contact by said live body is detected by said first input means.

2. The information processing apparatus as claimed in claim 1, further comprising display control means for controlling in such a way that information relating to said first input means is displayed when said first state is identified by said state identifying means.

3. The information processing apparatus as claimed in claim 2, wherein said information relating to said first input means includes information relating to a function assigned to said first input means, said information processing apparatus further comprising a function executing means for executing said function assigned to said first input means when said second state is identified by said state identifying means.

4. The information processing apparatus as claimed in claim 1, wherein said first input means comprises a jog dial for detecting the input based on physical contact by said live body when a depressing or rotational operation is performed.

5. The information processing apparatus as claimed in claim 1, wherein said first input means comprises a key as hardware having contacts and which detects the input based on physical contact by said live body as an on-state or an off-state of said contacts.

6. The information processing apparatus as claimed in claim 5, wherein said key is disposed above said cross points between said transmission electrodes and said reception electrodes.

7. The information processing apparatus as claimed in claim 6, wherein a plurality of said key is provided, and based on a detection by said second input means, said state identifying means further determines a third state where said live body is disposed in an area between a first key of said keys and a second key of said keys.

8. The information processing apparatus as claimed in claim 7, further comprising function assigning means for assigning a function corresponding to said third state, and

function executing means for executing said function corresponding to said third state assigned by said function assigning means when said third state is identified by said state identifying means.

9. The information processing apparatus as claimed in claim 8, wherein based on a detection by said second input means, said state identifying means further identifies a fourth state where said live body moves over a plurality of said keys in a predetermined direction;

said function assigning means assigns a function corresponding to said fourth state; and

said function executing means executes said function corresponding to said fourth state assigned by said function assigning means when said fourth state is identified by said state identifying means.

10. The information processing apparatus as claimed in claim 9, wherein said function assigning means further assigns to said keys a new function different from said functions which are already assigned to said keys.

11. The information processing apparatus as claimed in claim 10, wherein said first input means comprises a keyboard;

said function assigning means assigns a function corresponding to a left-click of a mouse to a certain key of said keys of said keyboard, assigns a function corresponding to a right-click of said mouse to a certain different key of said keys of said keyboard, said certain different key being different from said key to which said function corresponding to said left-click of said mouse is assigned, and assigns a function corresponding to a moving of a cursor by said mouse as a function corresponding to said fourth state; and

said function executing means makes said keyboard function as said mouse if said function executing means determines that a predetermined condition is satisfied, and based on an identification result by said state identifying means, executes one of said function corresponding to said left-click, said function corresponding to said right-click, and said function corresponding to the moving of said cursor by said mouse, each assigned by said function assigning means.
