序章
Have you ever thought that there is actually an “information treasure” hidden in every corner of the city?
From bus stops to 政府 halls, from traffic management to city squares, LEDディスプレイ are everywhere.
They are not just simple information display tools but also an important part of urban life. But have you ever thought about what unknown requirements and secrets are hidden behind these screens?
目次
1. Requirements for urban public service scenarios
1). Content display requirements
Simply put, the words on the screen must be understandable and clear. Don’t use ambiguous words.
For example, don’t write “almost there” on the bus stop sign; just write “10 minutes later” or “3 more stops” so that everyone will know.
Font size is also critical. For example, in a large place like a subway station, the words must be larger, at least 24 font.
If it is a close-up device like a self-service inquiry machine, the words can be smaller, but not less than 12.
Color matching is also very important, such as black words on a white background or white words on a black background, with high contrast, so that the eyes are comfortable to look at.
Also, there are many foreigners in many cities now, so it is best to be able to switch languages on the screen.
Common languages such as Chinese, English, Japanese, and Korean must be available, and the translation must be accurate so as not to make a fool of yourself.
The way to switch languages must also be convenient, such as pressing a button or shouting “switch language”.
2). Screen layout and design
The layout of the screen should not be messy but organized. Important information should be placed in a conspicuous position.
Such as emergency notifications and the most commonly used functions, which should be placed in a place where you can see them at a glance.
Unimportant information can be placed slightly more hidden.
For example, on the city information query screen, put the weather, traffic and other information that people often need to check in the middle or top of the screen.
Put the advertisements of surrounding businesses at the bottom.
Moreover, the information should not be piled up too much. Otherwise, it will be dazzling, and you will not be able to find anything.
If the screen is too small, you can divide the information into several pages or make a folding menu, and users can click on what they want to see.
In addition, the design style of the screen must match the overall style of the city. For example, in a city with historical and cultural heritage, the screen design can be antique.
In modern metropolises, screens must be simple, elegant, and technological.
Screen designs in the same city must also be unified, and fonts, colors, and icons should not be changed randomly so that everyone can use them easily.
2). Accessibility requirements
Accessibility is mainly for the convenience of people with special needs.
For example, for the visually impaired, the screen must have a voice broadcast function, the sound must be clear, the speed must be neither fast nor slow, and it must be the same as the content displayed on the screen.
Voice broadcast must also support multiple languages to facilitate visually impaired friends from different countries.
The way to trigger the voice broadcast must also be simple, such as pressing a button or shouting “broadcast”.
For the elderly with poor eyesight or people with low vision, the screen must have a low vision mode.
In this mode, the font should be enlarged by at least 18 points, and the color contrast should be high, such as white text on a black background or black text on a white background.
You can also add some auxiliary functions, such as the system automatically reading out the text when the user clicks on it or when the user operates; the system uses voice prompts so that everyone can use it more conveniently.
2. Requirements for traffic management scenarios
1). High visibility requirements
Imagine that you are driving under the scorching sun, and your eyes are almost dazzled. If the traffic screen on the roadside is not bright enough at this time, it will be terrible!
したがって、 輝度 of the traffic management screen must be very bright, so that people can see clearly even in strong outdoor light.
In addition, the screen 解決 must be high, just like a high-definition TV, so that complex traffic signs and various texts can be displayed clearly.
For example, the signs on the highway, the route, exit information, and speed limit signs on them must be clear at a glance, not blurry.
2). Real-time and accuracy
Traffic information is like a weather forecast and must be updated in time.
The content displayed on the screen must be synchronized with the traffic management system in real-time. Once the road conditions change, the screen must be updated immediately.
For example, if there is a traffic jam ahead or a traffic accident, this information must be displayed as soon as possible, and it cannot be discovered until the driver drives to the front.
At the same time, the displayed content must be strictly reviewed and cannot be wrong.
If the displayed route is wrong or the traffic sign is wrong, it will be troublesome, which may cause people to go the wrong way or even cause an accident.
In short, traffic information must be accurate and cannot fool people.
3). Weather resistance and reliability
Traffic management equipment must be like “iron”, especially strong. The screen must have functions such as waterproof, dustproof, and lightning protection, and it cannot “strike” because of heavy rain, strong wind, or thunder.
The equipment must also be able to operate normally in extreme weather; whether it is a hot summer, cold winter, or violent storms, it must work steadily.
After all, traffic management cannot stop for a moment, and the equipment must be online at all times.
If the equipment has problems at any time, it will be troublesome, and the traffic order may be in chaos.
3. Requirements for the government hall scene
1). Service information display requirements
The screen of the government hall is like a “navigator”, which must clearly display the key content such as the process and window information of government services.
For example, when applying for business licenses, social security registration, and real estate certificates, what are the requirements for each step, and what materials need to be prepared? This information should be displayed clearly.
In this way, when people come to the hall, they can figure it out by themselves without asking people everywhere.
In addition to displaying information, the screen must also have interactive functions to facilitate everyone’s work.
For example, in the queuing system, the screen must clearly show your number and how many people are waiting in front of you so that everyone knows what to do and doesn’t have to worry.
There is also a self-service query function. For example, if you want to check your social security payment record and provident fund balance, you can directly operate on the screen and quickly check it without waiting in line for staff to help.
2). Government image promotion
The screen in the government hall must also play the role of “promotion ambassador”.
The government has many good policies, such as entrepreneurship subsidies, tax incentives, and the progress of people’s livelihood projects, which can be displayed on the screen.
In this way, when people are doing things, they can also understand what the government is doing and how to serve everyone.
At the same time, the screen can also display some of the city’s achievements, such as which parks have been newly built, transportation is more convenient, and the environment has improved, so that everyone has a greater sense of belonging to the city.
However, the style of the government hall is solemn and formal, and the design of the screen must also conform to this style.
It cannot be as fancy as the advertising screens in ショッピングモール. It must be simple and generous, and people can feel comfortable.
For example, using steady fonts and appropriate color combinations makes people feel very professional.
3). Security and privacy protection
The screens in the government hall are not places where information is displayed casually. Security and privacy protection are very important. First of all, sensitive information cannot appear on the screen.
For example, personal ID number, bank card number, home address, and other private content must not be displayed.
Some internal documents and confidential information of the government cannot be leaked through the screen.
Secondly, information must be prevented from being tampered with or leaked.
For example, prevent someone from maliciously modifying the content on the screen or leaking information that should not be disclosed due to system vulnerabilities.
This requires professional technical guarantees, such as setting up firewalls, encrypting data transmission, and regularly checking system vulnerabilities.
In short, the screens in the government hall should not only facilitate everyone’s work but also ensure information security so no problems can occur.
4. Requirements for urban squares and public space scenes
1). Content diversity and cultural
The screens in city squares and public spaces are like a “loudspeaker” that shouts out all kinds of fun and interesting content.
For example, if there are any fun activities in the city recently, such as concerts, art exhibitions, traditional festival celebrations, etc.
They can all be seen on the screen so that people can take a look when passing by, and maybe they will find a place they really want to go.
In addition, the historical stories of the city must also be told. For example, why the old buildings were built like this and what celebrities lived here in the past can be displayed in the form of pictures, videos, and animations.
Imagine that there is a small animation on the screen telling old stories, and there is a narration next to it. How interesting!
When displaying art 展示会, you can also put high-definition pictures and accompany them with explanation videos to let everyone feel the charm of art in advance.
In short, the screen can have not only text but also pictures, videos, animations, and other fancy things. Otherwise, it will be boring!
2). Visual effects and aesthetics
The screen is not just a big screen, it must be “integrated” with the surrounding environment and cannot appear out of place.
For example, in a park, the screen can be designed to look like a small pavilion or blend in with the surrounding flowers, plants, and trees, and the colors must be well-matched so as not to appear too abrupt.
In a city square, the shape and style of the screen must also be coordinated with the surrounding buildings and sculptures and must not destroy the overall beauty.
The design of the screen should not be too fancy or too monotonous, and it should be comfortable for people to look at.
For example, the frame of the screen can be designed to be simple and generous, and the color should match the surrounding environment.
The screen image must also be clear, not blurred or mosaic; otherwise, it will be uncomfortable to look at!
3). Public interaction function
The screen must also be like a “message board for everyone” so that everyone can participate.
For example, a citizen message function can be set up to allow everyone to write their ideas, suggestions, or feelings on the screen.
For example, after an exhibition ends, everyone can leave a message to talk about their feelings.
A voting function can also be set up to allow everyone to vote for the most popular exhibits, the most anticipated cultural activities, etc., so that everyone feels more involved.
Moreover, the content of the screen should be updated conveniently, and people should not run around.
It is best to support remote control so that staff can update the content in the office using computers or mobile phones.
For example, if there is a new cultural event to promote today, or the citizen’s message needs to be updated, the staff can do it with just a few clicks; how convenient!
5。結論
After reading these requirements, do you have a new understanding of the LED display screens around you?
It turns out that these screens are not just cold equipment, but they carry the city managers’ care for the citizens, the inheritance of culture, and the pursuit of safety and convenience.
