Analysis of elevator interaction design may be the first you have seen

Mar 07, 2018

Begin to notice and observe the elevator's pushbutton panel because it is aware of the confusion that has arisen over the many differences in the design details of the two elevators that are frequently occupied. Elevators often "think differently" from one another. That is, a preset or established mental model has failed. We have to re-examine the elevator's control panel, recreate the mental model, and find the corresponding button. If you often take a few elevators daily operation rules and mental models between them is not the same, one is easy to make people confused, and two people increase the memory burden, it is very troublesome.

Feel that this small area is very interesting to operate it is worth analyzing, curious to find a lot of plans to study, a wide range of design is really make people feel a little headache. A little summary analysis of a variety of elevator keys on the design of the different and one of the various unreasonable.

One. Floor button

The overall shape of the problem

△ overall shape problems

In fact, this is actually the last thing that I think there will be problems in our daily life, the common elevator is basically a complete vertical and horizontal alignment of the layout. Alignment of the reason why the layout will become our minds, I think this is a bit followed by the structure of modern buildings, a building, each layer neatly there are several families next to each other, and then the top is to continue to follow this arrangement Logically layered code. Children draw simple strokes of the building, is also the first to draw the most outside of the big box, which as far as possible to regulate the entire painting aligned small box. This neat arrangement is a deep-seated cognition of the concept of "building" in our mind.

As shown above, a variety of unconventional elevator buttons, if used in everyday situations, is a failure. The daily life of the elevator, this is to help people save time, characterized by large traffic, high frequency and efficiency, the use of unconventional shape of the elevator button, people have to recognize it every time or memory This model of operation only allows passengers more annoyed. But if it is used in leisure and entertainment occasions, the theft is very suitable. Non-daily occasions, leisurely mood and plenty of time, people interested in the study of interesting things. If I am lucky enough to encounter, I will be very happy to take out the phone to take pictures.

2 button material problem

△ button material problems

The elevator button will have floor number and button integrated and two separate forms, where only the floor number and buttons are discussed.

Button common materials are white on silver, black on silver, black on white and black on white four (dark color, white background similar to black and white, black and white, not otherwise discussed).

To identify the analysis: As shown on the right EPb on the right side of the black and white, black and silver on black background, text and background can form a larger contrast, easier to identify. However, as shown on the left side of the figure BO silver white, the recognition is relatively low, more difficult to see non-face-to-face. The overall silver, as shown in S, has similar problems.

Response analysis after pressing: After clicking, the button needs immediate feedback of "successful operation". The feedback form also has a certain relation with the material of the button. Feedback form, individuals think through digital feedback is the optimal solution to describe the process of taking the elevator, there should be a definite target floor, looking for floor numbers, the corresponding operation of the digital button to confirm the success of the operation, to confirm the arrival of the target floor, the floor number is through Always a clue. In the example chosen, the BOPs are all white texts, and after pressing they all light up, the light perception is cut off on both the silver and the black background, the bottom is not changed, and the attention is focused on the number of operations and The BO also enhances feedback through "light-leak" processing of the outer ring. E button should be pressed after the entire light, which is the only possible black-white button feedback form, so the most dramatic change is the background color change, feedback enough, but slightly overshadowed. b is used only "light leakage" for the press feedback. S visual inspection is relatively easy to give people doubts, there is no gap outside the button, unlike the "light leakage" feedback, the operator can not immediately get the "press success" feedback (outer ring of green plastic is 0 layer Stress is not pressed button feedback), probably only through the elevator is moving to judge.

3. Designed for special people

Today, many public facilities and homes are beginning to be designed for special groups of people. This is precisely the embodiment of a country, a city, and humanistic concern for special groups such as blind paving, handicapped access in front of buildings, Braille and the fixed wheelchair position reserved in the most accessible compartments and much more. In the superficial sense, these designs are designed to ensure that special groups of people can travel independently; in the deeper sense, they also uphold their dignity and increase their possibility of self-reliance.

For a special population design, should be defined as not affecting the average person to use, but increase the cognitive burden of ordinary people under the premise of ensuring that special people can use and more convenient to use it alone travel. Now elevators are gradually starting to be considered by special people. However, in the opinion of individuals, there are still many problems and many designs can not be called "successful design for special people."

Braille and button

△ Design 1-- Braille & Buttons for Special People

Button design for the blind, this should be the most widely used for a special crowd design, the form is also more colorful.

The most common should be like S, the number and braille mark together on the same button, should also be the lowest cost method, only need to customize the button. However, the problem that individuals think exists is that it is difficult to grasp the boundary of touch and press (they do not understand the mode of operation of the blind, but think that there will exist such a problem, if there is misunderstanding). Imagine the blind touching the button area and trying to figure out how to figure out the pattern of alignment. Braille should be touched to exert a certain degree of force, but also to avoid pressing the button. It's easy to keep the blind in a tense situation, if it can not easily be mistaken.

U and c barely considered a type of design, the black area to put floor numbers and braille markers, buttons to provide the operation, such a separation to avoid the above-mentioned problems. However, the contrast between the two also exposes a problem that U does not consider intimacy. Look at the arrangement of U, presumably the work of industrial designers who have too much attachment to Alignment. Arranged very uniform, but the corresponding relationship between the black area and the button, you can not see clearly or find out clearly, we have to use the "reading is from left to right" experience or determine the smallest repeat unit before the correct operation. And c such a bite of the design is used to match the appearance of the two to form a natural association, is a relatively good design.

X design is more positive, to ensure that the blind can identify, but also to ensure that does not increase the identification burden on ordinary people, but also very beautiful, but there is no particular place worthy of commendation. J and T are better personal designs. The Braille area is made of the same raw material as the entire panel, closely aligned with the corresponding floor buttons, neither to unduly interfere with normal human identification nor to blind people. However, the design of the Braille area is slightly better than that of J and Braille is arranged on the same board for easy extension and touch.

Taboo number problem

△ designed for special populations 2-taboo number problem

There are some digital taboos both in East and West. West does not like "13" and China wants to avoid "4". Domestic elevator design should be avoided if it is to avoid numbers. To avoid these numbers, there are two kinds of situations: the first one shown in Figure A, skip this floor directly, this situation is very common; the second e, there is this floor, but by other means to avoid direct mention To it. I did not actually see the second situation, but also a bit curious about how braille in this situation should describe the taboo numbers. However, the first case of skipping over the floors can only cause some minor distress to the average person, but it is simply catastrophic to the blind. Really designed for the blind, considering the elevator they are using should be as shown in Figure J, with simple rules that are easy to find and remember. However, as shown in Figure f this elevator, I actually take over, for ordinary people is still very troublesome for the blind is a disaster elevator. The numbers are arranged laterally and not from the bottom left, lacking floors 2,4,13,14,24. For ordinary people there is absolutely no way to find the law of multiples to quickly find the desired floor, only to understand the rules of horizontal arrangement, the line-by-line to see or glanced at the approximate height of the size of the digital search. For blind people, secretly speculate about their mode of operation: groping the bottom of the button, roughly determine the number of columns, because there is no 2 No 4, the beginning of the lack of continuity of numbers, you may want to explore two rows of buttons to determine the arrangement rules, and then according to the number of columns and Arrange rules to find your own target floor, but the lack of 13,14,24, the number of laws equivalent to rebuild twice, but also increased the difficulty of finding the target floor. All in all, if you have taboo numbers, do not arrange horizontally, let alone blindly add braille for blind consideration.

Out of the button design to say a digression, even if the elevator panel design is very good, for the blind consider very thoughtful, are not enough. According to personal opinion, taking into account the key Braille design of the elevator, or did not reach the target floor of the sound feedback, if the blind ride alone, how to determine their correct arrival at the target floor? Elevator door opened, but no one waiting at the door Situation, I believe we have encountered. With this in mind, it is best to have an elevator door to report the floor function, not only to facilitate the blind, but also to facilitate the head of the family.

Disabled operation panel

△ designed for special populations 3 - disabled operating panel

In addition to considering the blind, some elevators also consider disabled people. Ordinary buttons are generally in the center of the right side of the door, the total return to the spatial or partial corner of the location, for the disabled, without the aid of tools, whether it is accurate to the corner position or the operation of the upper part of the button is very difficult of. Nowadays, many public facilities are internally located on the left and right sides of the lift, with separate push-button panels for handicapped persons, as shown in Figure Z. Figure Y, the separate operation panel with disabilities, but the same security in the corner position, can be said that there is no understanding of the use of the operation panel scene.

4. Arrange the direction of the problem

Horizontal and vertical

△ arranged in the direction of the problem 1 - horizontal and vertical

Most of the floor buttons are regular vertical and horizontal alignment mode, when speaking about the overall shape of the problem has already said that this arrangement should be based on people's psychological model of modern architecture, and in the vertical and horizontal alignment Under cloth, and only horizontal and vertical arrangement of two modes.

Figure O, K, take the horizontal arrangement mode, imagine how to find such a panel to find the number of floors you want to go. The first case is, in accordance with the habit of looking at the lower left corner, find the bottom, view the nearby figures, find the next layer, the line of sight by the anti "Z" gradually rose until you find the search for the floor; the second case is to see Arrange the bottom of the figure, find the law, in accordance with the laws of the number of floors to find the approximate location. Under normal operation, the two modes should be mixed. The description of these two operating conditions, but also people can clearly see the horizontal arrangement of the weaknesses: The first digital incremental direction view mode, the line of sight has been in reverse "Z" word, the horizontal one Row can not be placed too many numbers, so the line of sight has been in the "interrupt - another line - interrupt" loop, not a more consistent and comfortable recognition process; The second law of finding, through the parity or Multiple relations to a simple analysis of positioning, a bit cumbersome.

R is an ingenious horizontal cross arrangement that was inadvertently found: the numerical increment is from right to left rather than from left to right, which most people are accustomed to. This is really a problem that never occurred.

As shown in Figure P, A, taken by the vertical arrangement, and the natural law of rise of the floor, to avoid the interruption of the line of sight and find the law of the trouble, the problem is a more reasonable arrangement. However, in terms of P and A in terms of single pictures, there are also some discrepancies, so that the rider can quickly identify the arrangement, the best way is to imply by distance (the principle of formatting tower approaches the law) Pull the distance between the vertical row a little, you can reduce the difficulty of identification. However, I have seen the arrangement of keys, up to the figure A this type, the left and right buttons left and right sides of the gap is basically the same type, simply can not determine the arrangement according to the approximate form button must be based on figures. The panel shown in Figure P, however, has a greater distance between two vertical rows than the longitudinal distance between the buttons, but is more advantageous than horizontal separation, which is more obvious than distance division, erroneously inducing horizontal viewing mode, although this should not be custom behind The panel can be spliced assembly, but so cost-saving is ...


△ arranged in the direction of the problem 2 - oblique

Oblique is a more special and more rare arrangement, two rows of buttons scattered arrangement. This arrangement is disguised horizontal arrangement, and the horizontal arrangement of the problems are basically the same, but will be more friendly than the horizontal row, the line of sight turn will be softer. As shown in the three inclined elevator panels arranged roughly similar - two rows of patchwork arrangement, the more closely between the same row, identify more likely to find the bottom after the principle of proximity along the line Read up, understand the single and double number array pattern according to the law to find the target floor. L in order to imply the law of digital growth, 1-2 groove guide the top and bottom of the visual (of course, may also be cost-effective in the province), personally think that recognition will cause confusion, first reading side? Looking down the vertical row? Expected visual guidance useful? In fact, eye movement experiments should really be used here.

5. The number of columns

△ column number of questions

Believe that after reading the above, more or less there will be a little scalp tingling feeling, the heart of faint "too difficult, so complex, hard to find," such Tucao. Such a common thing in daily life, if people have a psychology, then it must fail.

Most of the problems in the number of columns appear on the high-rise elevators, the degree of scalp numbness due to the number of floors and arrangement of rows, consider Braille or not, Braille design merits and demerits, as shown in Figure C, a, H . H is simply a leader, guru, the number of floors more than the number of considering Braille also considered very bad, already had four more than 50 floor buttons, Braille marked out, at first glance the number of buttons is doubled Feeling, it is a headache.

The daily lifts are basically 1 to 3 columns, showing a narrow vertical rectangular layout as a whole, and the elevator shown in the same paragraph, the same elevator optional floor more than had caused difficulties (Hick's law), and because Arranged unreasonable deviate from the conventional layout, but also adds to the operator's identification difficulty. The complexity that an elevator can carry is limited, and the complexity that floor growth can bring is enormous. Therefore, the solution to the problem of the number of columns is to split the complexity to multiple elevators or reduce the complexity of the elevator itself (in fact, it should be said that the complexity is lost to the passengers). The former, as usual, The distinction between the single and double floor, the latter shown in Figure V every three floors of the design of the elevator (after each button has a distraction of the button, indicating the button for each of the three floors).

6. The total number of parity problems

△ total number of parity problems

This issue is arguably a small problem compared to the previous one, but it is also interesting to discuss the total parity problem for elevators with only two vertical rows of buttons. The total number of floors, there are two cases of parity: Even floor, then there are two kinds of arrangement, aligned and staggered one, as shown above Q, A; odd floors, roughly as shown E, d, W three arrangements , One more and one more wrongly.

In general, such as A, W such that the overall shape of the diagonal to the upper right of the quadrilateral morphology is the optimal solution, from the morphology more clearly implies the number of two vertical rows ascending relationship, but also to see the bottom of the After the initial floor, because there is no interference around the line of sight is very natural to go up, successfully hinted that the longitudinal arrangement led to longitudinal reading. E and d, aside from the horizontal arrangement, the problem that one considers to be a problem is the excessive attention paid to the "surplus". Symmetry elsewhere is quite high, attention is inevitably the first time to be more that one attracted to the past, in this sense, E is worse than d, to find a positive first than 7 to find, but d is completely in accordance with mathematics Rules to do the arrangement, the use of natural matching intuitive guidance to understand the longitudinal arrangement is better than the mathematical logic of rational logic need to be arranged, after all, not the best mind it!

Two. Switch button

And the floor button relative position problem

△ and the floor button relative position problem

There are about three relative positions of the switch button and the floor button:

And floor buttons are not distinguished at all, such as R.

A certain distance apart on it, such as A, D.

Be separated by a certain distance, such as B, E.

Do not distinguish between the mix is undoubtedly the worst arrangement, even the buttons of different functions, take the same style, put together, gives the intuitive feeling is that they are the same, completely failed to play a role in distinguishing, Operation need to be identified by symbols, or rely on experience to find. E is its counter-example, the switch door buttons and floor buttons not only made a distance division, but also made a radius of the type of distinction, very clear.

The switch button is the button with the highest operating frequency in all the buttons, which is better analyzed by using context. Single take, just press once to close the key, the situation is relatively simple, in the next are not too troublesome. But many people take a ride, it is easy to need to hold down the open key for a long time and the need to press the close button several times, for a long time the need for high-frequency operation of the button, the button needs to be put into operation more convenient and comfortable place, In the sense of speaking, it would be obviously better to place it on the top than below, and it would be more tiring to raise the hand while placing it on the bottom would be much easier.

2. The distinction between the two emphasizes the problem

△ distinguish between the two problems

Before discussing the distinction between opening and closing keys to emphasize problems, discuss the important differences between them. The elevator door open and close the door with the default duration set to reach the target floor automatically open the door, after about 5s automatically close the door, but the actual default length of the end often appear, but people have not finished or finished, or temporary someone to board the situation, it must have Open the door, and must be very responsive to sudden situations. Reached the default duration, the elevator door will automatically shut down, reach the default length of time still hold the open key, then release the door open elevator door will automatically close, so the close button is not necessary, even if the reaction speed will be slow 1 ~ 2s, in case of sudden situation. In summary, the importance of opening the door is higher than the close button.

The actual use of the elevator, switch door keys to emphasize the distinction between more forms:

There is absolutely no difference, such as O.

Cut off the relatively weak key, such as Q.

Use color to make distinctive emphasis, such as A, B (B with the red warning highlighted the close key, the use of the wrong).

Use size to distinguish, such as C (also considered Fitz law).

Use color, size to distinguish, such as I, the most complete consideration.

Three alarm button

Location problem

△ position problem

In fact, the problem is a bit similar to the position of the switch button. The biggest and worst problem is the mixing problem. The U, S, and K buttons in the figure above are all alarm buttons and other pattern mixes with exactly the same style or slightly struggling Change changed, with a warning color yellow, all very bad. The lowest operating frequency of the alarm button and other things together, really very easy to cause misuse, and the consequences of misoperation is generally more serious, it is easy to bring frustration, very unreasonable.

O, I is the more normal type, the most unusual operation of the alarm button directly on the top. But in fact, it is best to make some emphasis as I generally do, after all, although the operating frequency is low, it is very necessary for people to notice.

In fact, looking back, I also quite surprised that it looks very simple elevator panel, tossing out so many different problems and problems. Design is to solve the problem, is to allow people to solve the problem, the use of more elegant and refined tools, through a more simple and clear process, have a more comfortable and pleasant mood. It is unfortunate that many elevators are always in the midst of embarrassed search, or people who complain that they feel too bad memory. I hope everyone in the future, there are no points encountered elevator. Analysis of the more complicated things, the way is not the same, thanks for reading last.
