Interactive digital signage: what it is, where it helps and how to manage it

What interactive digital signage is

Digital signage is a system made up of one or more screens, the devices that play the content and the software that schedules and distributes it. It becomes interactive when an action by a person, captured for example through touch, gesture or a sensor, changes what is shown. A non-interactive system can also vary its content according to time or place: interactivity begins when it is the user who determines the system's response.

An example clarifies the distinction. A monitor in a lobby playing scheduled content, even content that differs by time of day, remains a non-interactive installation. If instead an interface lets someone search for a name or a room and returns the requested result, the system is interactive, because it answers a question asked by a person.

What distinguishes a system from a single screen

The question we are asked most often concerns exactly this point: when it makes sense to speak of a system and when a single device is enough. The answer depends on the number of points and on how often the content changes.

A single information point, with content that stays stable for months, is well served by a standalone kiosk. We covered this in the article on the multimedia kiosk, which remains the most direct solution when the aim is to provide information at one specific place. When the points are numerous or spread across several spaces and sites, and updates are frequent, a centralised platform simplifies scheduling and content distribution. Remote updating does, however, require connectivity, compatible devices, access management and monitoring functions, and it does not entirely remove the need for on-site technical work.

This is the stage where many projects become complicated. Hardware is bought once, while the schedule requires continuous management: at this point responsibilities, tools and update procedures need to be defined precisely.

Where interaction adds value

Shops and showrooms

A screen that responds to passage or gesture makes it possible to present a wider range than the one on display. An interface connected to the catalogue lets customers browse models, variants and configurations not available in store on their own; the effect on the purchase journey should be verified against objectives and indicators defined in the project. The context is the one we cover in the shops, hotels and showrooms section.

Corporate lobbies and welcome areas

In an atrium the system presents internal directions and corporate communication, adapting content to opening hours and to events under way, and, when integrated with internal processes, it can support visitor reception. Interaction is useful above all for searches and specific requests, and should be designed around the observed needs of the people who use the space.

Museums and exhibition spaces

Here digital signage serves orientation and service purposes, distinct from the content of the exhibition route: opening times, maps, notices, events. Keeping the two levels separate makes the editorial structure clearer and simplifies daily management.

Trade shows and events

Centralised management makes it possible to change the content of every screen on the stand within minutes. It is a concrete advantage when the day's programme changes or when the message needs adapting to the audience present at that moment.

What to assess before choosing

Some elements affect the result more than the choice of screen model.

The first is position, which determines legibility and therefore the brightness required. A screen exposed to direct light calls for different characteristics from one placed in a controlled environment, and no software setting compensates for a wrong choice on this point.

The second is viewing distance, which decides type size, pixel density and the amount of information per screen. The third is content management: who produces it, how often, with which tool. The fourth is accessibility: an interface designed for touch alone excludes part of the audience, and in some public contexts accessibility is a requirement.

The final element is measurement. An interactive system can return information on how many people stop, which content is consulted and at what times. This data helps to understand whether the installation is working, and it must be handled in compliance with data protection law.

How we approach a project of this kind

We start from the list of information the public actually looks for in that space, collected from the people at the counter or the front desk, and from how often it changes. It is this frequency, more than the number of screens, that determines the architecture of the system.

We then define the appropriate level of interaction: in some environments it is enough for content to change according to the time of day, in others the person needs to be able to search, choose and go deeper. Our IMUV touchless sensors allow interaction without touching the screen, which is useful where the flow is continuous or where hygiene is a requirement. We build the content around the company's visual identity, because an installation that looks like a generic template communicates little, and we leave the client a simple tool to update the schedule. The overall picture is in the section on interactive communication.

When a project calls for particular surfaces, such as shop windows or architectural volumes, we consider technologies other than the traditional screen, from transparent LED film to the three-dimensional effects that require no glasses and that we covered when writing about 3D billboards.

The mistakes that recur

The first is installing screens without deciding who will update the content: after a few weeks they show outdated information and the public stops looking at them. The second is filling the screen, because a person standing reads few words and gives up in front of a long text. The third is interactivity added without a purpose, with screens inviting a touch that offers nothing useful. The fourth is neglecting routine maintenance and the checking of connections: these omissions are the most common cause of screens that are off or stuck on an error message.

How to start

A first assessment requires the number and position of the planned points, the type of information to be shown, the update frequency and the lighting conditions of the spaces. With these elements we can indicate which architecture holds up, which level of interaction makes sense and which checks are needed on site before defining the project.
