Description
Technical field
The present invention relates to interactive display system, and relate more specifically to a kind of interaction display system with the pattern of emphasizing
System.
Background technology
Interactive display of the prior art perceives the position of the electronic pen on its surface using electronic whiteboard.Work as calculating
Machine show be devoted on blank and correct position after it is possible to by manipulate electronic pen on blank draw write to manipulate calculating
Machine shows, just as the mouse using computer.The problem that this interactive whiteboard can allow the teacher to according to audience is fast
Process fastly and explain material, its use improves efficiency of teaching, also strengthen the understanding of student simultaneously.This blank makes excellent
The digital teaching material of matter is used, and also sound and vision technique is used for data processing and displaying.
The typical structure of electronic whiteboard includes driving and sense wire in the working surface disposed behind or beneath of electronic whiteboard
The array of circle or matrix, thus forming interaction surface, its coil is interacted with the electromagnetic component in this device indicating.
Electronic whiteboard can also be associated with the interaction table being used or graphic tablet by system user.This figure input
The structure of plate can be similar with electronic whiteboard, but smaller.Grid array can be arranged be connected with working surface, to be formed
Interaction surface, and user can use the instruction device work on such surface being suitable for interacting with this interaction surface
Make.
It will be noted that graphic tablet can be used independent of electronic whiteboard.For example, as it is known that they are used as department of computer science
The input unit of system, wherein graphic tablet can substitute " mouse and pad " structure.
In current whiteboard system structure, and in the structure of the graphic tablet using for computer input,
Instruction device typically provides pen shaped arrangement.Typically it had been thought that pen shaped arrangement is the natural choosing being used together with interaction surface
Select because its simulate most of users familiar to the operation write on paper of pen.
This pen typically can be provided with button, and its function is identical with the button of computer mouse.In a kind of structure,
By realizing pushing of button to this interaction surface pressing pen in the axial direction.
Easily affirm, be electromagnetic technique, rather than touch screen technology provides top quality input unit.But it is existing
The electromagnetism interaction surface technology having technology does not also provide and meets the technical scheme that user all requires.Due to showing of electronic whiteboard
Show the significantly increase that area is than regular display, demonstration people need to move in very large range when the control in interface is demonstrated in operation
Dynamic, for needing the operation to emphasize portions of display content for the interim adjustment display pattern, iterate through the controls such as menu, button and change
Become the time that display pattern can take demonstration too much, and the attention of possible dispersed audience, affect demonstrating effect.Thus need one
Plant and there is the easy to use display system emphasizing pattern.
