projected touch screen display

Introduction:

              Basically, there are two world in technology and engineering depending upon which ideas and applications are designed & implemented

                        a> analog world

                        b> digital world

there is a third world called the real world, from where an object has the direct or indirect access to these analog as well as digital world. Form the real world an object has the direct access to the analog world and indirect access with the digital world through analog world.

example: now a day’s every computer system have 95% of digital function and remaining of 5% have the analog functionality to interact with the real world object .

Before going to the depth of this project, must aware about the touch screen display. In the electronic term a touch screen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. The touch screen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touch screens).

example: let us suppose there is a folder in display named file manager if the user want to access this folder ,just touch the folder through which the user will get access to this folder. There is no need of clicking by mouse or else.

So, there is a interaction between the real world and the digital world (i.e. the object is interacting with the digital world totally, or the interaction is 100% ).

Key:

The theme of this project is to bring the digital world in the real world and make a interface real world object with the real world system.

Design ideas:

Q. how to bring the digital functionality in the real world?

Sol: This can be done by the projection technique. We have to create a image pattern of the display by projection which consist of information.

Q. how to make the interface between object and the projected digital information?

Sol: The interface can be done by using digital eye (camera).

Imagined ideas:

1.     There must be a device consisting of processing units which will be connected to a system by Bluetooth/by physically.

2.     A camera will be there for sensing the input. The camera acts as a digital eye.

3.     A device (unknown) will be there to produce the light beams.

4.     The light beams will create the image pattern, which consist of information.

5.     Some software’s may be need for this.

Issues:

1.     When an object will touch a folder on the projected screen, the camera will take the coordinate of the folder, it will result a console response to the system not on the projected screen.

How to operate the projected image (think....) ?

Solution:

                                                                             

I.                   There may be a solution.. we can use a glass type material which acts as a display system & have the same functionality like a display device.

Any Batter solution....?
