Overview of APP visualization theory

In the process of information transmission, "information source", "media" and "audience group" have become the key three elements. With the continuous progress of science and technology, "media" has also gradually transited from "mouth" and "text" to the transmission of pictures, tables and other ways in the past, realizing the visual development of information.

visual communication features first, high speed. Network information transmission has a speed that other modes of communication can't match. Once the information is uploaded to the Internet, it will spread to all parts of the world within a second. Users only need to click the mouse and turn on the TV to know the information of all parts of the world in the first time. Secondly, large capacity. Network information involves various aspects of information, from astronomy to geography, all kinds of information is everywhere, no matter which aspect of information users want to know, they can quickly find the information they need through simple search. Finally, interactive. Different from traditional information, network information provides users with a platform for communication and interaction. That is to say, users can share their own opinions and get to know other users' comments in it, which improves the interactivity of information.

information transmission of users' cognitive characteristics is a process in which "information source" is perceived by "audience group" under the influence of "media". The psychological perception of "audience group" includes three types, namely "instant perception", "short-term memory" and "long-term memory".

Instantaneous perception is a process of extremely short duration, which is roughly maintained in 50-60 milliseconds. In this memory state, the audience will generally only have a momentary perception of the image and sound image of the information source. At this time, the audience usually processes the information they perceive by direct coding.

The time of short-term memory is mostly maintained at about one minute, and the audience in this state will basically experience memory decline in about one minute. Meanwhile, the audience will process the information they receive by indirect encoding. According to the research, people in the stage of short-term memory, will be in the form of "block" memory, that is to say, in the brain, will automatically collect their own information to classify processing, the same or similar information into the same memory
