Why exhibits are a hard case
User experience design is the practice of shaping how a person feels and behaves when using something, so that it is easy, clear and worthwhile. Most of its ideas come from software and websites. Exhibits are a harder case for three reasons.
- There is no onboarding. A visitor will not read instructions, create an account or learn a system. The interface must make sense in seconds.
- Use is brief and shared. Sessions may last under a minute, and other people are watching or waiting.
- Visitors are varied. One screen serves children, older adults, first-time users and people who speak other languages, often at the same time.
The aim is that someone can walk up cold and succeed. Good design here is mostly about removing obstacles.
Clear navigation
Navigation answers three visitor questions: where am I, where can I go, and how do I get back? On a small phone screen people tolerate hidden menus. On a gallery screen they tend not to.
A few reliable habits:
- Keep the structure shallow. Most exhibits work with two or three levels at most.
- Offer a visible way back to the start on every screen, such as a clearly labeled home button.
- Use words that describe the destination, not internal jargon. “See the objects” is clearer than “Collection module.”
- Show current position, such as highlighting the active section, so visitors do not get lost.
- Limit choices per screen. A handful of options is easier to scan than a long grid, though the right number depends on the content.
Visitors who cannot predict where a button will take them tend to stop pressing. Consistent placement and labeling reduce guesswork. For visitors with memory or attention differences, simple navigation is also a core part of cognitive accessibility.
Feedback
Every touch deserves a visible response. A button that changes appearance when pressed, a short animation when a page changes, or a sound where sound is appropriate all confirm that the system heard the visitor. Without feedback, people press again and again, double-trigger actions, or give up.
Feedback should be quick; delays of more than a moment feel like failure. If something takes longer, such as loading a large image, show a progress indicator. Error messages should say what happened and what to do, in plain language, not codes. Touch problems that come from hardware, such as poor touch calibration, can feel to the visitor like a fault in their own action, so test input reliability as part of the experience.
Affordances and cues
An affordance is a visual hint about how something can be used. Buttons that look raised or outlined, text with underlines, and arrows that suggest swiping all tell a visitor what is possible. Flat designs with unlabeled icons can look pleasing but hide the function. When in doubt, pair an icon with a short word.
Size and spacing matter, too. Targets that are too small or crowded lead to mistakes, especially for older adults, children and anyone with limited dexterity. Good touch targets are larger and spaced further apart than many designers first expect.
Consistency and simplicity
Use the same pattern for the same action across the whole exhibit. If swiping moves between images on one screen, it should do so on others. Cut features that are not needed. Every extra control is another thing a visitor has to notice and understand, and the temptation in exhibits is to show everything.
Usability testing
The central practice of user experience work is watching people try to use the thing. The method is straightforward and does not need a lab.
- Prepare a rough version, even paper sketches.
- Ask a few visitors or volunteers who resemble your audience to try a simple task, such as finding out when an object was made.
- Stay quiet and watch. Note where they hesitate, tap the wrong thing, or ask a question.
- Fix the biggest problems, then test again with different people.
Even a small number of sessions often reveals the most serious problems, though the right number depends on the project and how varied the audience is. The people who built the exhibit are the worst testers, because they know where everything is. This kind of prototype testing belongs before the build is finished, when changes are cheap.
Accessibility belongs to user experience
A usable exhibit works for people with different abilities. Screen height and reach ranges affect wheelchair users. Color contrast and text size affect low vision visitors. Captions help people who cannot hear the audio, whether because of hearing loss or a noisy room. These are not extras added at the end; they are part of making the exhibit usable by the people it is for.
Keeping the human side
User experience is not just efficiency. A well-designed exhibit also feels welcoming, trustworthy and a little rewarding. The usual measure is simple: after the first use, can a visitor tell what they learned, and would they be comfortable pressing the next thing? If so, the design is doing its work.
