In general, the touch screen has a conventional screen display function and a user interface function. That is, when a user writes a character or a symbol or draws a picture on a panel covered with liquid crystal, or draws a picture, the pointer moves on its path to display its shape, and when the icon on the screen is touched in a specific mode, the corresponding function is performed. The screen according to the function execution is displayed.

The personal portable information device is provided with many touch screens as described above, providing convenience in information collection, storage, creation, retrieval, and communication functions.

Due to the development of the touch screen technology, a 3D touch screen has recently been developed and used.

The 3D touch screen may be implemented as a capacitive touch screen, an IR touch screen, an EMR digitizer, and the like.

The capacitive touch screen measures a capacitance between a finger or a conductor and a touch screen sensor to determine whether a contact is made by comparing a specific value with a specific value.

The IR touch screen detects an IR value at an IR receiver located outside the display device by scattering IR generated from the IR pen on the surface of the display device. The detected value is compared with a threshold to determine whether a contact is made.

The EM digitizer may check the proximity using an EM-electromagnetic resonance (EMR) between the EM sensor plate and a dedicated pen.

Conventional touch screens can be fed back by touch or by vibration of sounds, actuators, etc., but the 3D touch screen as described above has the user not being provided with feedback in the non-contact area, so the user has a 3D touch screen. I feel inconvenient when using this equipped device.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily understand and implement the same.

1 is a block diagram of a 3D touch screen device according to an embodiment of the present invention.

3D touch screen device 10 according to another embodiment of the present invention, 3D touch screen unit 11 for recognizing the approach of the object from a certain distance until the contact; A feedback providing unit 12 providing preset sound information or vibration corresponding to a depth coordinate of the object entering the 3D touch screen unit recognition area; A memory unit 13 storing sound information or vibration information corresponding to the depth coordinates of the object; And a controller 14 for detecting an object entering the recognition area of the 3D touch screen, calculating a 3D coordinate of the object, and instructing the feedback provider to provide feedback corresponding to depth coordinates.

The object refers to any object used as an interface between the 3D touch screen and the user, and includes, for example, a conductor, a finger, an IR pen, an EMR pen, and the like according to a touch screen method.

The 3D touch screen unit 11 does not recognize only 2D coordinates (xy coordinates) like a conventional touch screen, but gradually or linearly from the distance from the surface of the screen to a predetermined distance. I can recognize it.

The feedback providing unit 12 provides preset sound information or vibration corresponding to the depth coordinates of the object entering the 3D touch screen unit recognition area.

In an embodiment of the present invention, sound information or vibration is used as a method for providing feedback to the user, and the feedback provider 12 provides the sound information or vibration to the user.

Therefore, the feedback providing unit 12 may include a sound device for generating sound or a vibrator for generating vibration.

In addition, the feedback providing unit 12 is characterized in that the sound information or vibration is generated differentially according to the depth coordinates of the object, which will be described in detail with reference to FIGS. 2 and 3.

The memory unit 13 stores sound information or vibration information corresponding to the depth coordinates of the object.

Accordingly, the feedback providing unit 12 generates sound information or vibration corresponding to the depth coordinates of the object calculated by the control unit 14 with the information stored in the memory unit 13.

The controller 14 detects an object entering the recognition area of the 3D touch screen, calculates three-dimensional coordinates of the object, and instructs the feedback provider to provide feedback corresponding to depth coordinates.

The controller 14 detects an object entering the recognition area of the 3D touch screen. At this time, an unintentional object may also be detected, so the controller 14 may approach an object to actually input, for example, a conductor, a finger, Eye pen, EM pen, etc. should be selectively detected. Accordingly, the method may further include disregarding an object that is simply unintentionally approached for the purpose of input to the 3D touch screen.

In addition, when the object enters the recognition area of the 3D touch screen, the controller 14 calculates three-dimensional coordinates of the object.

That is, the conventional touch screen method recognizes only when the object touches the screen, so only two-dimensional coordinates are required to identify the contact point. Since we need to calculate the three-dimensional coordinates of the object.

Various methods for calculating the 3D coordinates may be used, and representative examples thereof include a capacitive touch screen, an IAL touch screen, and an EM digitizer.

The capacitive touchscreen measures a capacitance between a finger or a conductor and a touch screen sensor to determine a contact by comparing a specific value with a threshold value, and how far the object is from the plane of the screen. To calculate.

The capacitive touchscreen panel is coated with a material that stores a charge. When the panel is in contact, a small amount of charge is attracted to the point of contact. Circuits at each corner of the panel measure the charge and send this information to the controller for processing. Capacitive touchscreens are not affected by external factors and have high transparency.

The IR touch screen detects an IR value at an IR receiver located outside the display device because IR generated from the IR pen is scattered on the surface of the display device. The detected value is compared with a threshold to measure the contact and the distance between the screen and the object.

The EMR digitizer may measure the proximity and distance by using an EMR between the EM sensor plate and the dedicated pen (EMR; Electro-Magnetic Resonance).

In the present specification, the above three methods are described as a method of calculating 3D coordinates, but the present invention is not limited thereto and it can be implemented using other methods.

The control unit 14 that calculates the three-dimensional coordinates of the object by the above method or the like instructs the feedback providing unit 12 to provide sound information or vibration corresponding to the calculated depth coordinates as feedback.

The feedback providing unit 12 provides sound information or vibration corresponding to the depth coordinates of the object as a feedback according to the command of the control unit 14.
