The electronic whiteboard is a product that people are constantly improving. The electronic whiteboard can be used in certain things, such as teaching, meeting, etc. Therefore, it is effective to have a whiteboard teacher to move in and out without having to move the projector. Improve the proportion of teacher information into teaching. However, there are some shortcomings in the use of the electronic whiteboard. For example, when writing on an electronic whiteboard, the range that can be written is only the range of the visible whiteboard, and the stretching cannot be continued, so it is necessary to wipe and rewrite, and the previously written content is Will disappear, when you want to supplement the teaching in the review or repeated reference, you need to write it again or verbally, which will make the learner unable to have a deep memory; and when the teaching process, its data is in order Under the tumbling, when reviewing or repeating the key supplements mentioned earlier, it is also necessary to click the page to jump back to the data page before M357676; and the general electronic system clearing function is covered by the stack. The method is mainly based on the background color, and the same color is applied to cover the block to be removed. If the writing is to be repeated again, it is covered again in the background area, resulting in repeated stacking of data and delaying the operation of the entire system. It is a waste of time in use and it is impossible to make the teaching process smooth. In addition, with the increasing popularity of the Internet, the ultimate goal of website designers is to allow viewers to stay on the site for a longer period of time, so the way the page is designed is gradually transformed from a traditional text-oriented approach to In a multimedia-oriented way, most of the Internet users can be retained. Secondly, I hope that the website can further understand the needs of consumers. For this reason, a set of Internet-based software will come into being. With Flash, designers can easily place multimedia effects on their websites. Flash can be played on different platforms.
