Interactive Panel for an Exhibition: How to Choose One and Prepare Content

The interactive panel for the exhibition should be selected not according to the maximum diagonal, but according to the scenario: who will approach the screen, what a person should do and how much time he has. For catalog or navigation, convenient height, rack stability, and large interface elements are important. For a presentation to a group, visibility from a distance is more important. To collect applications - a fast script, an understandable keyboard and predictable work without the Internet.

Short answer: first, fix one main scenario, then select the installation type and only then the diagonal. Before opening the site, check the content on the same device, with the same cables and the same connection method that will be used on the stand.

Define the panel task first

The phrase "you need a touch panel for the exhibition" is not enough for selection. The same equipment works differently as an electronic catalog, a map, an application form, or a large screen for a presentation.

Purpose	How a visitor interacts	What to check first
Product catalog	Scrolls through the cards, compares, opens photos and videos	Interface speed, large buttons, return to home screen
Navigation or map	Searches for an object and builds a route	Signature readability, scaling, search operation
Collecting contacts	Fills in the short form	On-screen keyboard, consent to data processing, offline storage
Group Presentation	Looks from a distance, is controlled by an employee	Viewing angle, text size, separate control method
Interactive game	Quickly clicks, drags and drops items	Response delay, multi-touch, automatic script restart

If there are several scenarios, assign the main one. A screen that simultaneously tries to show a catalog, a long presentation, a form, and a corporate website is usually more difficult for the visitor than four separate functions in the menu.

How to choose the installation format

Vertical panel on rack

Suitable for catalogue, navigation, questionnaire and short demonstration. Check the height of the core: the main buttons should not be too low or require constant arm raising. The rack must remain stable when the user taps on the edge of the screen.

Interactive table

It is appropriate when several people work around the interface, you need to consider a map, a site plan or a set of materials. The corners of the interface, protection against accidental touching with the palm of your hand and clear orientation of the content are especially important for the table.

Kiosk in the building

Used for self-service, registration and scenarios with peripherals: printer, scanner, camera or reader. Here, the hardware and software need to be designed together. If non-standard logic is required, prepare in advance technical assignment for software for a touch kiosk.

Large panel for presentation

If the primary user is an employee on the stand and the audience is looking from a distance, the touch layer may be secondary. In this scenario, readability, brightness under site conditions, image output method, and backup control are more important.

The diagonal is selected after the distance and layout

There is no universal diagonal "for the exhibition". A small screen may be more convenient for a personal questionnaire, and a large one for a map or group presentation. Before you book, answer four questions:

1. Is the user standing close to or watching from the aisle?
2. Is one person or group working at the same time?
3. What is the minimum text size in the layout?
4. Does the stand have restrictions on width, height, and safe walkways?

A useful test is to open a real 1:1 scale layout on a screen of close size. The screenshot on the laptop does not show whether it is convenient to reach the navigation and whether the signatures are readable in the exhibition lighting.

What to check on the connection

The touch screen transmits at least two different types of signals: image and touch. For some models, the video goes over HDMI or DisplayPort, and the sensor goes over a separate USB. In other configurations, both signals can transmit a compatible USB-C.

Dell and BenQ documentation separately draws attention to the correspondence of video input and Touch USB. Therefore, the phrase "there is a picture" does not mean that the touch part is connected and works.

Before the event, check:

• an accurate panel model and a set of ports;
• a computer or media player that will run the content;
• video cable and touch cable;
• adapters and the permissible length of the route;
• power, mains filter and location of the socket;
• automatic start after switching on;
• behavior after internet loss or reboot
• a backup set of cables and a local copy of the content.

If you're using an employee's laptop, turn off notifications, sleep mode, and random desktop access in advance. A separate kiosk mode or a specialized application is more reliable for a public terminal.

How to prepare content for the touch screen

A regular website or PDF can be opened in the panel, but this does not make them convenient to touch. Remove small links, hover effects, and long shapes. Do not expect that the user will accurately fall into the elements created for the mouse.

In WCAG 2.2 for web interfaces, the minimum touch target is described as an area of at least 24 by 24 CSS pixels or a sufficient distance between targets. For the exhibition interface, this is often not enough: the physical screen, the user's position, and the public environment require a check on the device, not just a formal match to the number.

A good exhibition interface usually has:

• one intuitive start screen;
• major actions without hidden navigation;
• short texts and visual hierarchy;
• a return button on each deep screen;
• automatic return to the beginning after inactivity;
• local upload of critical images and videos
• understandable response to an error or lack of network;
• clearing the form and personal data after the session.

If there is no ready interface, you can order development of software for touch panels, rather than trying to adapt the desktop site just before installation.

What materials to transfer to the rental contractor

Send more than just the date and address to get the exact configuration. The short brief should contain:

1. Dates of installation, work and dismantling.
2. Address, number of the pavilion or hall, rules of entry.
3. Stand layout and available space for equipment.
4. The main scenario and the expected number of concurrent users.
5. Content format: website, app, video, presentation, PDF.
6. Requirements for the Internet and the possibility of offline work.
7. The need for delivery, installation and duty of a specialist.
8. Connected periphery and image source.

You can view available formats in rental equipment catalogue. The final configuration depends on the dates, site and scenario, so it is better to confirm it after checking the content.

Acceptance checklist before opening the stand

The inspection is carried out not in an abstract office, but in conditions as close as possible to the site.

• The panel is securely fastened, the cables do not create obstacles.
• The image fills the screen and has the correct orientation.
• The touch coincides with the pressing point throughout the active zone.
• The main buttons are available to people of different heights.
• Content starts automatically when enabled.
• There is a clear way back and an automatic session reset.
• The video plays with or without sound according to the script.
• The form saves data and behaves correctly without a network.
• The employee knows how to restart the app and who to call if the app crashes.
• The backup version of the content is stored locally.

For a one-time exhibition, it is usually more rational rent an interactive panel in St. Petersburg together with material inspection and installation. The purchase makes sense when the equipment is used regularly and the company has a person responsible for storage, updates and technical support.

FAQ

Is it possible to open a regular website on the interactive panel

It is possible if the site is adaptive, does not depend on hover effects and has sufficiently large elements. Before the exhibition, you need to check it on the real screen, in full screen mode and with unstable Internet. For a critical scenario, it is better to prepare a local or offline version.

Which is better for the exhibition: a touch panel or an interactive table

The panel is more convenient for individual catalog, navigation and form. The table is suitable for working together with a map, plan, or multiple objects. The solution does not depend on the status of the equipment, but on the position of the users and the interaction scenario.

Do I need a separate computer

Depends on the model and content. Some panels have a built-in system, others need an external computer or media player. Non-standard application, integrations, and peripherals more often require a pre-agreed computing configuration.

Will the sensor work via HDMI

HDMI typically transmits an image, but not necessarily transmits a touch. The touch function of a particular model may require a separate USB or a compatible USB-C. The scheme must be checked against the panel documentation.

How many days in advance to book a dashboard

The earlier the dates and the site are known, the greater the choice of equipment and time for the content test. For a project with non-standard software, complex logistics or multiple devices, you need a separate stock for development and rehearsal.

Is it possible to collect contacts of visitors offline

Yes, if the form and local storage are designed for offline mode, and synchronization occurs after the connection is restored. The rules for storing, cleaning and transferring personal data must be determined before launching.
