Abstract

An electronic apparatus with a touch function includes a screen and an input device. The input device includes a transparent plate and a signal detector. The transparent plate and the signal detector are disposed on the screen, and the signal detector is electrically coupled to the electronic apparatus through a connecting interface. The signal detector has a detecting range on the transparent plate and detects a location of a target object located within a detecting range by a non-touch detecting way to generate a first coordinate data, such that the electronic apparatus controls an operation thereof according to the first coordinate data.

Claims

1. An electronic apparatus with a touch function, comprising:

a screen; and

an input device, comprising a transparent plate and a signal detector, the transparent plate and the signal detector being detachably disposed on the screen, the signal detector being electrically coupled to the electronic apparatus through a connecting interface, the signal detector having a detecting range on the transparent plate,

wherein the signal detector detects a location of a target object within the detecting range by a non-touch detecting way to generate a first coordinate data so that the electronic apparatus controls an operation thereof according to the first coordinate data.

2. The electronic apparatus of claim 1, wherein the screen has a first frame and a second frame, the first frame and the second frame form a first corner, and the signal detector is disposed on the first corner.

3. The electronic apparatus of claim 1, wherein the signal detector outputs the first coordinate data to the electronic apparatus through the connecting interface, and the electronic apparatus converts the first coordinate data to a second coordinate data so that an operating system of the electronic apparatus operates according to the second coordinate data.

4. The electronic apparatus of claim 1, wherein the non-touch detecting way comprises emitting a first signal by the signal detector into the detecting range, and, if the target object located within the detecting range, the signal detector receives a second signal reflected from the target object to generate the first coordinate data.

5. The electronic apparatus of claim 4, wherein the first signal is an ultrasonic wave or an infrared light.

6. An input method of an electronic apparatus having a screen and a transparent plate disposed on the screen, wherein the input method comprising:

providing a detecting range on the transparent plate;

detecting whether or not a target object is located within the detecting range by a non-touch detecting way;

generating a first coordinate data if the target object is located within the detecting range; and

transmitting the first coordinate data to the electronic apparatus through a connecting interface to operate the electronic apparatus.

7. The input method of claim 6, wherein the non-touch detecting way is carried out by light detecting or sound wave detecting.

8. The input method of claim 6, wherein the transparent plate on the screen is detachable.

9. The input method of claim 6, further comprising converting the first coordinate data to a second coordinate data so that an operating system of the electronic apparatus operates according to the second coordinate data.

10. The input method of claim 6, wherein the non-touch detecting way comprising emitting a first signal into the detecting range, and, if the target object located within the detecting range, generating the first coordinate data.
