## Abstract

An electronic switch apparatus for a vehicle, may include a projector module implementing a plurality of switch images, a sensor module detecting locations of respective switch image by recognizing the switch images implemented by the projector module as two-dimensional images, an infrared module emitting infrared rays to areas of the switch images displayed by the projector module, and a control module for, when a specific area of the switch images may be touched, detecting coordinates of the specific area by measuring light reflected from emitted infrared rays of the infrared module, and executing an operation of a switch corresponding to the coordinates.

## Claims

### Claim 1

An electronic switch apparatus for a vehicle, comprising:
a projector module implementing a plurality of switch images;
a sensor module detecting locations of respective switch image by recognizing the switch images implemented by the projector module as two-dimensional images;
an infrared module emitting infrared rays to areas of the switch images displayed by the projector module; and
a control module for, when a specific area of the switch images is touched, detecting coordinates of the specific area by measuring light reflected from emitted infrared rays of the infrared module, and executing an operation of a switch corresponding to the coordinates.

### Claim 2 (depends on 1)

The electronic switch apparatus as set forth in claim 1,
wherein the switch images implemented by the projector module further comprise at least a mode conversion switch image; and
wherein, when one of the at least a mode conversion switch image is touched, the control module displays switch images having other shapes than the plurality of switch images.

### Claim 3 (depends on 2)

The electronic switch apparatus as set forth in claim 2, wherein, when one of the mode conversion switch images is touched, the control module forms a group of switch images having other shapes, and then displays the group.

### Claim 4 (depends on 2)

The electronic switch apparatus as set forth in claim 2,
wherein each of the mode conversion switch images is formed to correspond to a relevant switch image; and
wherein, when the mode conversion switch image is touched, the control module replaces the corresponding switch image by a switch image having another shape.

### Claim 5 (depends on 1)

The electronic switch apparatus as set forth in claim 1, wherein the plurality of switch images is implemented on upper portion of a console.
