Description

Display and writing device

The present invention relates to a display and writing device, and in particular, to a display and writing device that can be used for two-way information processing.

The whiteboard is a plastic white writing platform that can be repeatedly written and wiped on the writing surface of a special whiteboard pen. However, there are common problems in traditional techniques, and the information written on the whiteboard is limited to live viewing. To others who are in different places, they can only use their manpower to copy their contents in the form of copying or depicting, which often leads to the difference between the contents of the transcript and the original data or the details of the details, so it is necessary to revisit the user on the board. The difficulty of drawing the chart on it is very high.

In view of this, in order to overcome this situation, the predecessor has invented an electronic whiteboard that can record, copy, and digitize the contents on the board. The electronic whiteboard can realize paperless office and teaching by applying the principle of electromagnetic induction, combined with a computer and a projector.

The electronic whiteboard is divided into two principles according to the working principle: the pressure sensing principle and the laser tracking principle. The touch-sensitive whiteboard using the pressure-sensing principle is equivalent to a touch screen of a computer, and is a human-machine interactive input device that performs a designated work with a finger or a brush and an option displayed on the screen. The electronic whiteboard has two layers of pressure sensitive film inside. When a certain point on the surface of the whiteboard is under pressure, the two layers of film cause a short circuit at this point, and the controller of the electronic whiteboard detects the coordinate value of the pressed point (finger or stroke) And the location), sent to the computer via the RS232 interface. A laser emitter on each side of the upper end of the whiteboard using the laser tracking principle. After the whiteboard is started, the laser emitter emits a laser to scan the surface of the whiteboard, and the special pen has an inductive laser function to return the position of the pen.

From the perspective of development, the earliest electronic whiteboards were copy-type electronic whiteboards. With the development of technology and the needs of the market, interactive electronic whiteboards appeared. Currently, the two types of electronic whiteboards coexist on the market, and the following two types of electronic whiteboards are separately introduced.

Interactive electronic whiteboard: Interactive electronic whiteboard can communicate with the computer, connect the electronic whiteboard to the PC, and use the projector to project the contents of the PC onto the electronic whiteboard screen, in the support of specialized applications. Underneath, you can construct a large screen, interactive collaborative meeting or teaching environment. Using a specific stylus instead of a mouse to operate on the whiteboard, you can run any application that can edit, annotate, save, etc. any operation that can be done on the computer using the keyboard and mouse. Connect the electronic whiteboard to the PC. The electronic whiteboard at this time is equivalent to a tablet with a very large area. It can be written, drawn and instantly displayed on the PC. The file is saved as a graphic file. It can be described as a computer. One of the surrounding products.

Copy-type electronic whiteboard: The so-called copy-type electronic whiteboard can scan and print the content written on the whiteboard in a certain way by the user's simple operation. The function completion process is the same as the ordinary copying process. First, the content on the whiteboard is collected by the image sensor. After the signal is processed by a certain image, the other columns are used by thermal, inkjet or laser printers. Print mode output.

Furthermore, the interactive electronic whiteboard can be used for two-way input and output functions after being equipped with a computer, but the complexity of the erection, maintenance and use of the system is relatively high. In addition, although the function of the copy-type electronic whiteboard is relatively basic, the structure is simple, the cost is low, the use is convenient, and the basic needs of the people can be achieved, so that the copy-type electronic whiteboard is uniformly selected in each office. However, although existing devices can allow on-board information to be unidirectionally output in digital and paper format, images cannot be reproduced in both directions by means of an electronic whiteboard.

Accordingly, it is an object of the present invention to provide a display and writing device that can be used for two-way information processing, solving the problems of the prior art.

According to a specific embodiment, the display and writing device of the present invention comprises a flexible interface module, a scanning module, a rolling module and an operation module. The flexible interface module provides a writing surface and displays the captured content. The scanning module captures an image of the writing surface and generates a captured content based on the image. The scrolling module can move the flexible interface module and pass the scanning module. In addition, the operating module is electrically connected to the flexible interface module, the scanning module and the rolling module for the user to operate the flexible interface module, the scanning module and the rolling module.

According to another embodiment, the display and writing device of the present invention comprises an interface module, a scanning module, and an operation module. As mentioned earlier, the interface module can provide a writing surface as well as display content. The scanning module can move back and forth over the interface module along the scanning direction to capture an image of the writing surface and generate the captured content according to the image. In addition, the operation module is electrically connected to the interface module and the scanning module for the user to operate the interface module and the scanning module.
