Digital signage as a driving force in digitalization

Digital signage describes the use of digital display systems for a variety of purposes, such as advertising, customer information or internal communication. While traditional, static displays in the form of posters or boards become less relevant in the long term, the demand for dynamic, connected and interactive displays has increased significantly. This change is closely linked to the digitalization of our society, where information should be available around the clock and customers expect personalized, engaging experiences.

The term “interactive digital signage” refers to the fact that users not only passively consume content, but can actively interact with the content using touchscreens, gesture control or other technologies. Examples include displays that respond to touch, voice assistants that answer questions, or image-based interactions where the device's camera plays a role. These intensive experiences have the potential to increase the attention of target groups, anchor brand messages more firmly in people's minds and increase customer loyalty in the long term.

At the same time, technologies such as artificial intelligence (AI), big data and the Internet of Things (IoT) open up new opportunities to increase the effectiveness of digital signage and always adapt the content to the needs of the respective target group. Interactive digital signage is used in a wide variety of sectors: retail, banking, healthcare, hospitality, education, public administration and beyond. This makes the technology a flexible key for modern communication.

Market overview: The global development of interactive digital signage

The global market for digital signage has been growing steadily for years. Various factors are driving the increasing demand. On the one hand, companies want to be able to use digital displays to adapt their brand messages in real time and quickly display updates. On the other hand, the increased affordability of displays and their components means that smaller and medium-sized companies can also invest in digital signage.

Increasing technological maturity and falling prices

Technological advances in the areas of displays, touch functions and network-based content have made a significant contribution to the fact that digital signage is now established in many areas. In addition, hardware components such as screens, controllers and sensors have become cheaper in recent years. This price drop favors projects in which multiple displays of different sizes are used or in which various interactive solutions are networked to work in an omnichannel approach.

Diverse applications in various industries

The increasing spread of digital signage can be seen in numerous industries:

• Retail: Interactive displays help customers discover products, access information or configure items in real time. Directions and electronic price tags are also included here.
• Banking: Bank branches use digital displays to reduce waiting times, provide information about financial products or provide interactive advice.
• Hospitality: Hotels and restaurants integrate digital signage to dynamically adjust menus, inform customers about offers or optimize the check-in process.
• Healthcare: In clinics and doctor's offices, interactive displays are used to provide patients with information material and to optimize waiting areas.
• Entertainment and leisure: Cinemas, museums and amusement parks are increasingly relying on impressive installations that offer visitors a memorable experience.
• Education: Schools and universities use digital signage for room and timetables, announcements and even for digital, interactive learning in classrooms.
• Public administration and smart cities: Traffic information, information for tourists, digital signposts or warning messages can be disseminated quickly and effectively using digital signage.

The ability to add interactive elements and make content customizable clearly differentiates interactive digital signage from classic print or television campaigns. “Communication in real time” becomes the key term for sustainable customer relationships.

Key trends: From AI to the omnichannel experience

Digital acceleration is constantly driving new trends and applications in interactive digital signage. Some of the key developments can be summarized as follows:

Artificial intelligence and data analysis

AI-based technologies make it possible to evaluate huge amounts of data and transfer the insights gained to displays in real time. Thanks to modern algorithms, companies can better understand their target group and personalize content in a targeted manner. Whether gender recognition for tailor-made advertising messages, weather data to adapt offers or location-based services – the possibilities are diverse. “The more personalized the content, the higher the likelihood of a positive reaction,” is a common motto.

Omnichannel strategies

More and more companies are pursuing a holistic approach in which digital signage is networked with other communication channels. The goal: A consistent brand experience, whether in a brick-and-mortar store, online or via mobile apps. Interactive displays play a key role here by dynamically adapting content and creating relevant links to e-commerce, social media or customer loyalty programs. For example, a catwalk video shown in a shop window can be advertised in parallel on a fashion house's website. As a result, customers experience the brand image as uniform and consistent.

Integration with mobile devices

Smartphones and tablets have become an integral part of everyday life. By interacting with mobile devices, digital signage can further accelerate information and purchasing processes. For example, viewers of a display scan a QR code to receive additional information or to complete a purchase. At the same time, they can provide feedback in real time, for example through votes or surveys. Beacons and NFC chips are also increasingly being used to initiate personalized interaction.

Sustainability and energy efficiency

In times of climate change and increasing environmental awareness, the topic of sustainability is also becoming increasingly important in digital signage. Measures include the use of energy-saving displays, intelligent lighting technologies or resource-saving production processes. At the same time, many manufacturers are working to increase the lifespan of their devices, while operators are increasingly relying on sustainable packaging and disposal. “Green progress” here means: technology that is not only efficient, but also responsible towards people and the environment.

Smart Cities and IoT

More and more cities are using digital signage for traffic control, urban development or public information. By connecting to sensors and other IoT devices, data can be collected and visualized in real time. This can help to avoid traffic jams, improve parking guidance systems or disseminate emergency information more quickly. “Smart cities have recognized that information has to be alive – digital signage is ideal for this.”

Strategies and best practices for interactive digital signage

If you want to pursue a successful digital signage strategy, you should think beyond the mere use of displays. Below are some crucial aspects to increase the effectiveness of digital campaigns:

Target group-oriented content

“Knowing your own customers is the key.” This is how many marketing managers put it. Content should not only be visually appealing, but above all relevant. A coherent content strategy is based on the interests, age and needs of the users. In a clothing store, for example, an interactive display could be used on which customers use avatars to try out different outfits and see directly how they look on them.

Integration of smartphones

Smartphones enable users to access further information using QR codes, for example, or to log in to their customer account to receive personalized recommendations. For example, a restaurant could place a display in the queue that shows current menu suggestions. Guests scan a QR code and land on an ordering platform to reserve their table or meal in advance.

Creative implementation and interaction design

“The first impression counts!” – Digital signage must be designed to be visually appealing in order to stand out from the flood of advertising messages. This involves the choice of color, arrangement of content, font size and the possibility of playful interaction. Gamification elements – i.e. the use of playful mechanics – can further increase attention. For example, an interactive kiosk could provide a quiz in which users win prizes.

Content management systems (CMS)

Smooth, central control and updating of all displays is essential to reduce costs and ensure content consistency. A powerful CMS allows you to plan campaigns, display content depending on day, time and location, and automatically adapt to external factors (e.g. weather or special events).

Measurable goals and key figures

A clear definition of goals and success indicators forms the basis for every digital signage project. Whether increasing sales, increasing brand awareness or reducing waiting times - only if goals are measurable can success be checked and the strategy readjusted if necessary. “Success control is at least as important as creativity,” is a statement heard again and again in marketing departments.

AI-powered analytics

AI can help evaluate large amounts of data in real time. In this way, information can be obtained about the average time spent in front of the display, the age and gender of the viewer can be estimated, or reactions (e.g. facial expressions) to certain advertising offers can be analyzed. Companies that use such insights are able to deliver their content in an optimized manner and achieve higher conversion rates.

Challenges: data protection, security and costs

Despite all the advantages of interactive digital signage, there are a number of challenges that should not be underestimated:

data protection

As soon as personal data is processed – for example via facial recognition or location recording – legal and ethical questions arise. In many countries, especially in Europe, strict data protection regulations must be observed. “Transparency about data collection and use is mandatory,” experts emphasize again and again. Lack of consent or violations of data protection laws can result in severe penalties.

IT security and cyber attacks

Digital displays are usually networked in order to be able to flexibly control content. This opens up potential points of attack for hackers. From manipulating the payout to accessing internal databases - companies must establish protective measures such as encrypted transmission, firewalls, regular software updates and penetration tests.

Technical complexity and integration

A successful digital signage solution is made up of many building blocks: hardware, operating system, CMS, network and security infrastructure, if necessary AI modules and analysis tools. The complexity is growing quickly, so projects require sound planning and specialist staff. Small companies are often faced with the task of integrating external service providers and thus providing financial resources.

Costs and profitability

Acquisition and operating costs can be high - especially if large-format LED walls or numerous screens are installed. To ensure the return on investment (ROI), there must be clear goals and appropriate use of the technology. Not every company needs highly complex systems; Sometimes smaller, more cost-effective installations can achieve the desired effect.

Digital transformation in small and medium-sized companies

In order for digital signage to be used successfully, a change in working methods and structures often has to take place. This applies to marketing as well as sales, the IT department and logistics. The necessary resources and skills are more likely to be available in large corporations than in small or medium-sized companies. Accordingly, additional staff often have to be trained or hired.

Opportunities: Added value for communication, brand and customer loyalty

Due to its dynamism and interactivity, digital signage offers a wide range of opportunities to create added value for companies and institutions:

Improved customer communication

Interactive displays allow a more direct exchange with the target group. Customers can play with the content, access desired information or even provide individual feedback in real time. This shifts communication from a one-sided advertising message to a dialogue, which can increase trust in the brand.

Increasing brand awareness and emotionalization

Dynamic, visually appealing content is often more memorable than static posters. Emotions can also be amplified by combining images, sound, animation and sometimes even haptic effects (such as a vibrating floor). “Where emotions are aroused, bonds are created” is a frequently used motto in the marketing world.

Increase sales and cross-selling

Digital signage can inform potential buyers precisely about special offers, new products or suitable additional items. For example, in a clothing store, a digital shop window could advertise rain jackets depending on the weather when it is raining outside. This type of real-time, personalized advertising increases the likelihood of prospects becoming buyers.

Optimization of internal processes

Digital signage cannot only be used externally. Companies also use screens and kiosks for internal communication or to digitize work processes. Employees can receive important information, register for training courses or take part in surveys at the touch of a button. Especially in larger organizations with multiple locations, communication channels can be standardized and accelerated.

Location attractiveness and location marketing

Cities and communities benefit from digital signage by directing visitor flows and making attractions more accessible. This applies, for example, to tourism regions that use interactive information kiosks to present their guests with current event information, route recommendations or hotel availability.

Germany is an important market for digital signage, but there are deficits in international comparison, especially in the area of ​​interactive displays and large-scale installations. Although many companies already use digital screens in shop windows or reception areas, complex, AI-supported solutions are still rare. There is often a lack of willingness to take risks and quick decision-making processes to extensively test new technologies.

“German companies should further expand their innovative strength,” say many industry experts. At the same time, there are structural hurdles that can slow down growth. These include:

• Regulatory requirements: Data protection, building law and local approval procedures can delay the expansion of digital display infrastructures.
• Financing: Financing interactive digital signage projects is often a challenge, especially for small companies, when public funding is lacking.
• Skilled labor shortage: There is a lack of specialized experts in many areas of IT and engineering. This can lead to projects taking longer or sometimes failing.
• Reluctance in user acceptance: In many regions there is still skepticism towards comprehensive data collection and AI-based solutions. Companies must therefore focus more on information in order to refute data protection concerns.

Nevertheless, Germany has the opportunity to position itself better in the race for interactive digital signage. The engineering skills and reputation for high-quality technologies could be a decisive advantage if they are specifically linked to start-up culture and government funding.

Recommendations for German companies and political decision-makers

In order to move Germany forward as a technology location in the area of ​​interactive digital signage, there are various starting points:

• Promoting innovation: “Germany needs more courage to test new technologies on a large scale” is an often expressed wish. Government programs could support pilot projects or offer tax relief.
• Creation of standards and guidelines: Data protection and security are particularly high priorities in Germany. Common standards that provide clear guidelines on how, for example, facial recognition can be used in a data protection-compliant manner create security for providers, municipalities and consumers.
• Training and further education: Targeted funding of technical training and courses that teach content such as AI, interaction design or network technology can counteract the shortage of skilled workers. At the same time, existing employees should attend further training to better implement digital signage projects.
• Share best practice examples: There is often a lack of visibility of successful digital installations. Exemplary examples could be made more public through networks, industry associations or trade fairs.
• Collaboration between science and business: Universities, research institutions and companies should cooperate closely to develop application-oriented solutions. This strengthens the transfer of knowledge and accelerates the market readiness of innovations.

Digital signage is changing

Interactive digital signage solutions will continue to gain in importance in the future. On the one hand, the hardware becomes more powerful, cheaper and at the same time more energy efficient. Displays are becoming more flexible in shape and size, which could lead to new applications in vehicles, on building facades or even in clothing. “It is conceivable that in a few years screens will be so thin and flexible that they will be attached to walls like wallpaper.”

On the other hand, the integration of AI and big data continues to advance. In addition to facial recognition and gesture control, methods for speech recognition, emotion recognition and advanced text analysis are being refined. Displays could record the mood of passers-by in real time and adapt content accordingly. Augmented reality (AR) and virtual reality (VR) will also play a larger role in the future by enabling immersive experiences.

The role of 5G and other new mobile communications standards will also be crucial. More bandwidth and lower latencies make it possible to process even more data in real time, integrate high-resolution live streams or display dynamic multiplayer experiences on public displays. Digital signage could thus form a kind of technical backbone in cities that connects countless interaction points.

Another trend concerns individual personalization. While today a lot of content is already shown to target groups, it could be even more fine-tuned in the future. For example, displays recognize regular customers, greet them personally and suggest products that match their shopping behavior. Challenges regarding privacy and ethics remain an important topic and will continue to be controversial.

Digital signage for interactive displays has long since become more than just “a screen in a shop window”

Global development shows a diverse range of possible applications and strong growth rates that will continue in the coming years. Leading countries such as the USA, Canada, China and South Korea are demonstrating how targeted investments in technology, infrastructure and research can revitalize entire sectors of the economy. Depending on the market environment, there are different focuses: While North America focuses on market readiness and AI-based personalization, China focuses heavily on scalable LED solutions and South Korea impresses with its innovative strength in display technologies.

Other countries, including Germany, can learn a lot from these developments. Interactive displays are more than just an advertising channel - they represent an opportunity to enter into a dialogue with target groups, strengthen customer loyalty and improve internal processes. At the same time, they bring with them challenges such as data protection, security and financial aspects. In order to overcome these hurdles and fully exploit the potential of digital signage, what is required above all is an open culture of innovation, a clear strategy and the willingness to adapt new technologies.

German companies should increasingly rely on user-friendly solutions, a targeted content strategy and AI integration in order to remain competitive on the international market. Political support, for example in the form of funding programs and clear legal frameworks, will help create a dynamic ecosystem in which digital signage projects can grow successfully. This sets the stage for us to take on a leading role in Europe and perhaps even worldwide in the coming years when it comes to innovative and interactive digital signage solutions.

“The future belongs to those who are courageous to seize the opportunities offered by interactive displays.” This quote sums it up: Digital signage is neither a short-lived trend nor a niche product. It is a promising technology that fundamentally changes the way we communicate information. Whether in retail, in public spaces or in educational institutions - those who familiarize themselves with technological developments early on and are prepared to invest in innovation projects will benefit from the numerous advantages in the long term.
