Abstract

Disclosed herein is an input device including, a target creating section a performing section, and a height information generating section wherein the target creating section generates the information on the target to which information the height information is added, and the performing section performs predetermined processing on a basis of the height information added to the information on the target.

Claims

1. An input device having an input unit for receiving light corresponding to an external input, and allowing input to a plurality of points on an input surface of said input unit, said input device comprising:

target creating means for generating information on a target indicating a series of external inputs on a basis of temporal or spatial positional relation of input parts to which the inputs have been performed;

performing means for performing predetermined processing on a basis of the information on said target; and

height information generating means for generating height information indicating height of said target from said input surface on a basis of an amount of light received in said input unit;

wherein said target creating means generates the information on said target to which information said height information is added, and

said performing means performs predetermined processing on a basis of said height information added to the information on said target.

2. The input device according to claim 1, further comprising,

event creating means for recognizing an event indicating a change in state of said target on a basis of the information on said target, and generating information on said event,

wherein said performing means performs predetermined processing on a basis of the information on said event.

3. The input device according to claim 2,

wherein said event creating means recognizes said event when the height indicated by said height information added to the information on said target is in a predetermined range.

4. The input device according to claim 1,

wherein said input unit displays an image on a display screen corresponding to said input surface of said input unit.

5. The input device according to claim 4,

wherein when there is a target whose height indicated by said height information added to information on said target is a first threshold value or less, said performing means sets said target as a target to focus, and displays predetermined keys in proximity to the target to focus, said predetermined keys being included in a software keyboard formed by a plurality of keys displayed on said display screen, in a magnified state on said display screen, and

when the height indicated by said height information added to the information on the target to focus becomes a second threshold value or less, said second threshold value being smaller than said first threshold value, or when the height indicated by said height information added to the information on the target to focus becomes more than said second threshold value after becoming said second threshold value or less, said performing means selects one key in proximity to the target to focus among said predetermined keys, and inputs information corresponding to said one key.

6. The input device according to claim 4,

wherein when there is a target whose height indicated by said height information added to information on said target is a first threshold value or less, said performing means sets said target as a target to focus, and displays a menu item including a plurality of items on said display screen, and

when the height indicated by said height information added to the information on the target to focus becomes a second threshold value or less, said second threshold value being smaller than said first threshold value, or when the height indicated by said height information added to the information on the target to focus becomes more than said second threshold value after becoming said second threshold value or less, said performing means selects one item in proximity to the target to focus among said plurality of items, and performs predetermined processing corresponding to said one item.

7. An input device according to claim 4,

wherein when there is a target whose height indicated by said height information added to information on said target is a first threshold value or less, said performing means sets said target as a target to focus, and displays predetermined photographs in proximity to the target to focus, said predetermined photographs being included in a photograph list of a plurality of photographs displayed on said display screen, in a magnified state on said display screen, and

when the height indicated by said height information added to the information on the target to focus becomes a second threshold value or less, said second threshold value being smaller than said first threshold value, or when the height indicated by said height information added to the information on the target to focus becomes more than said second threshold value after becoming said second threshold value or less, said performing means selects one key in proximity to the target to focus among said predetermined photographs, and performs predetermined processing on said one photograph.

8. A control method of an input device, said input device having an input unit for receiving light corresponding to an external input, and allowing input to a plurality of points on an input surface of said input unit, said control method comprising the steps of:

generating information on a target indicating a series of external inputs on a basis of temporal or spatial positional relation of input parts to which the inputs have been performed;

performing predetermined processing on a basis of the information on said target; and

generating height information indicating height of said target from said input surface on a basis of an amount of light received in said input unit;

wherein in a process of said target creating step, the information on said target to which information said height information is added is generated, and

in a process of said performing step, predetermined processing is performed on a basis of said height information added to the information on said target.

9. A program for making a computer perform control processing of an input device, said input device having an input unit for receiving light corresponding to an external input, and allowing input to a plurality of points on an input surface of said input unit, said program comprising the steps of:

generating information on a target indicating a series of external inputs on a basis of temporal or spatial positional relation of input parts to which the inputs have been performed;

performing predetermined processing on a basis of the information on said target; and

generating height information indicating height of said target from said input surface on a basis of an amount of light received in said input unit;

wherein in a process of said target creating step, the information on said target to which information said height information is added is generated, and

in a process of said performing step, predetermined processing is performed on a basis of said height information added to the information on said target.

10. An input device having an input unit for receiving light corresponding to an external input, and allowing input to a plurality of points on an input surface of said input unit, said input device comprising:

a target creating section configured to generate information on a target indicating a series of external inputs on a basis of temporal or spatial positional relation of input parts to which the inputs have been performed;

a performing section configured to perform predetermined processing on a basis of the information on said target; and

a height information generating section configured to generate height information indicating height of said target from said input surface on a basis of an amount of light received in said input unit;

wherein said target creating section generates the information on said target to which information said height information is added, and

said performing section performs predetermined processing on a basis of said height information added to the information on said target.
