GUI is a concept proposed by Doug Engelbart, a wizard of "human-computer interaction" in the 1960s. It makes the computer easier for users to accept. Since Apple introduced the first computer equipped with GUI in the 1980s, GUI has always been a human-machine tool. Interactive representation. VUI is not a new concept. Its predecessor is IVR (Interactive Voice Response), which was born in the 1970s and became popular in 2000. As long as the phone user dials the number designated by the mobile operator, he or she can listen, on-demand or send the desired voice information according to the voice operation prompts, and participate in interactive services such as chatting and making friends. The new generation of VUI refers more to people interacting with computers b2b data through natural language, so it can be considered that VUI is the representative of human-computer interaction in the era of artificial intelligence.
Before talking about GUI and VUI, let's talk about vision and hearing, because the difference in the use of senses will directly lead to the difference in GUI and VUI design.
If you ask what is the most essential difference between GUI and VUI, I think it is the difference in the dimension of conveying information. The information received by the eyes is determined by the four dimensions of time and space XZY axis; the information received by the ear can only be determined by the time dimension.
Although the ear can detect the direction and frequency of the sound, it is not the decisive factor.
Time determines how much information is received, it is unidirectional, linear and cannot be stopped. The information received by the ear in a very short period of time is very limited. To give a limit example: if a person can stop time, sound cannot be transmitted during the static time, and there is no information at this time; there is another saying that During the static time, the sound always maintains a current state such as "di~~~", at this time, the sound is a kind of noise to human beings. The information received by the ear can only be determined by time.
The eye, on the other hand, is very different, and can pick up a lot of information from space even in a short amount of time. The information of space is determined by two factors: 1. Dynamic or static; 2. Three-dimensional space or two-dimensional plane. In the absence of comparison with other reference objects, the stillness of things can simulate the stillness of time. At this time, people can obtain information from still things. The combination of time and space determines the size of the information. For example, spending one minute looking at dynamic things around you can get much more information than looking at the same static page for a year.
There is also an important difference, the eye can look back and forth in space to obtain information; the ear can only obtain information in one direction, and it is impossible to re-hear the first few seconds of information without the help of other functions.
Comparison of the amount of received information
The amount of information received by sight is much higher than that of hearing. Excellent respondents on Zhihu with topics on neuroscience and brain science pointed out that the upper limit of information received by the brain per second through the eyes is 100Mbps, and the upper limit of information received through the cochlea is 1Mbps. Simply put, the amount of information received visually can reach 100 times the amount of information received by hearing.
