I began to pay attention to and observe the button panel of the elevator because I was confessed that I had different details in the design details of the two elevators I used. Elevators are often different from what they think, that is, the default or established mental model has failed. We have to re-examine the elevator's operation panel, re-establish the mental model, and find the corresponding button. If you often take several elevators on a daily basis, the operating rules and mental models between them are different. One is easy to make people confused, and the other is to increase the memory burden. It is very troublesome.
I feel that this small piece of operable area is very interesting and worthy of analysis. After curiously looking for a lot of pictures to study, the variety of designs is really a bit of a headache. A brief summary of the differences in the design of various elevator buttons and the various irrationalities.
One. Floor button
Overall pattern problem
△ Overall shape problem
In fact, this is the problem that I did not expect at all. In our daily life, the common elevators are basically a regular horizontal and vertical alignment layout. Alignment layout has become a routine in our minds. I think this is a bit of a modern building structure. In a building, each floor is neatly arranged with several neighbors, and then the upper layer continues to follow this arrangement. Logical layer code. The building where the child draws a stick figure is also the first to draw the outermost big box, and then try to regulate the small squares that are aligned. This neat arrangement is a deep-rooted perception of the concept of "building" in our impression.
A variety of unconventional styling elevator buttons, if applied in everyday situations, are very unsuccessful. The Villa Elevator in daily life is designed to help people save time. It is characterized by large traffic, high frequency of use and efficiency. Using unconventional elevator buttons, people have to recognize it or remember it every time. This operational model can only make the rider more annoyed. But if it is used in recreational situations, stealing is considered to be very suitable. Non-daily occasions, relaxed moods and plenty of time make people interested in researching interesting things. If I am lucky enough to meet, I will be very happy to take out my mobile phone to take pictures.

2. Button material problem
△ button material problem
The elevator button has two forms of floor number and button integration and separation. Only the floor number and button are discussed here.
The common materials of the buttons are white on silver, black on silver, black on white and white on black (deep color, white on white, black on white, white on black, no discussion).
Analysis of the identification: the white on the white background, the white on the black background and the black on the silver as shown in the EPb on the right side of the figure above, the text and the background can form a large contrast, which is easier to identify. However, the white on the silver side presented by the BO on the left side of the above figure has a relatively low recognition degree and is unsightly when it is not normal. The overall silver, as shown in S, has similar problems.
Response analysis after pressing: After clicking, the button needs to give immediate feedback of "operational success", and the form of feedback also has a certain relationship with the material of the button. In the form of feedback, the individual believes that the digital feedback is the optimal solution. The process of taking the elevator should describe the target floor, find the floor number, operate the corresponding number button, confirm the operation success, confirm the arrival of the target floor, and the floor number is running through. Always a clue. In the selected example, the BOP is white text. After pressing, the numbers are illuminated, the silver bottom and the black bottom are separated from each other, and the bottom does not change. The attention is focused on the number of operations, and The BO also enhances feedback through the "leakage" process of the outer ring. After the E press, the whole button should be lit. This is also the only possible form of feedback for the black button on the white background. In this case, the most intense change is the change of the background color. The feedback is enough, but it is too overdone. b is the feedback feedback using only "light leakage". S visual inspection is relatively easy to give people doubts, there is no gap outside the button, unlike the "leakage" feedback, the operator can not immediately get the feedback "whether the press is successful" (outer ring green plastic is on the 0 layer Emphasis is not on the feedback of the button), it can only be judged by whether the elevator moves or not.
