When we talk about accessibility in buildings, most people think of physical accessibility: ramps instead of stairs, wide doors for wheelchairs, elevators of sufficient size. These infrastructural adjustments are undoubtedly important, but accessibility involves much more. People with reduced mobility, visual, hearing, cognitive or temporary disabilities — such as after surgery — have different orientation needs.
Traditional signs reach fundamental limits here. Visual signs don't help blind people. Complex directions overwhelm people with cognitive disabilities. Small lettering is inaccessible to visually impaired people. Acoustic announcements do not reach deaf people. The solution lies in digital, adaptive navigation systems that can be flexibly adapted to individual needs.
The most fundamental aspect of barrier-free navigation is the consideration of different mobility profiles. A wheelchair user absolutely needs routes via ramps and elevators, while a disabled person with a walker prefers shorter routes with seating options. A person after an operation should avoid stairs, even if they are the fastest route.
Intelligent navigation systems such as Accuras make it possible to select different route profiles. Users define their profile once — wheelchair, limited mobility, no stairs, slow pace — and the system automatically calculates suitable routes. This personalization takes place in the background, without users having to re-dial each time they navigate.
The route calculation takes into account more than just avoiding barriers. It shows estimated walking times based on restricted speed, marks rest benches along the way and warns of longer distances without seating. Alternative routes are shown if the primary route is unexpectedly blocked.
People with visual disabilities struggle every day with inadequate visual contrasts, too small fonts and unfavorable color combinations. Digital navigation systems can systematically remove these barriers if they are designed accordingly.
Customizable font sizes are a fundamental aspect. Users should be able to display text as large as they need without the interface breaking or important information disappearing off-screen. High-contrast modes with strong black and white contrasts make reading much easier when you have poor eyesight.
Color blindness affects around eight percent of the male population. Navigation systems must not rely exclusively on color coding — such as red and green markings without additional symbols. Patterns, icons, and text labels should complement or replace color information.
Screen reader compatibility is essential for people with severe visual impairment. All elements must be correctly labelled, images must be provided with alt texts and navigation must be completely controllable via keyboard or voice. The app must be structured in such a way that screen readers read out information in logical order.
For blind people, purely visual navigation is useless. Turn-by-turn voice output is becoming the primary method of navigation. The system must give precise verbal instructions: “Turn left in 15 meters”, “Straight to the second door on the right”, “lift in 5 meters on the right.”
The quality of the voice output makes a huge difference. Natural-sounding text-to-speech engines in multiple languages are required. The speech rate should be adjustable — experienced screen reader users often prefer significantly higher speeds than standard users.
Integration with external screen reader apps such as VoiceOver on iOS or TalkBack on Android is particularly valuable. Navigation should respect and harmonize with these system tools, not fight against them. Users often have years of experience with their favorite screen readers — navigation must adapt, not the other way around.
Haptic feedback via smartphone vibrations can supplement acoustic cues. Short vibrations when reaching a waypoint, longer when changing direction, specific patterns for stairs or elevators — these additional signals significantly improve orientation.
People with cognitive disabilities, learning difficulties or dementia need particularly clear, simple navigation. Complex instructions such as “Turn right after the third intersection, walk past conference room A and then take the second door on the left” are overwhelming.
Simple language is essential here: short sentences, specific instructions, one step at a time. “Go straight ahead” instead of “Follow this corridor.” “Turn left” instead of “Take the passage on the left.” Each instruction should only contain one action.
Visual support through clear arrows, images of landmarks and progress indicators also helps. A bar that shows how much of the journey has already been traveled provides safety and orientation. Landmarks — “Pass by the cafeteria entrance” — are more helpful than abstract distances.
The ability to return to or repeat previous instructions is important. Not everyone remembers multi-step instructions the first time they listen. A large, easily visible repeat button should always be available.
Language barriers are often overlooked restrictions. International patients in hospitals, tourists in museums, foreign students at universities — they are all struggling with foreign-language signs. Digital navigation can support any number of languages without having to multiply physical signs.
Modern systems such as Accuras support dozens of languages with one-tap switching. The language selection should be prominently placed, ideally as soon as the first app launch or QR code scan. Automatic recognition based on device settings helps, but can always be overwritten manually.
The complete translation is important, not only of the interface texts, but also of all place names, instructions and descriptions. Half-translated doesn't help — if room names suddenly appear in the original language, orientation is difficult again.
Accessibility does not only affect people with permanent disabilities. A mother with a stroller has similar needs as a wheelchair user. A tourist with heavy luggage avoids stairs. Someone with a broken leg needs temporary barrier-free routes.
Flexible navigation systems allow temporary profile adjustments. A user can activate “no stairs” for the duration of a hospital visit without permanently changing their profile. After recovery, the setting can simply be deactivated.
Situational factors also play a role. In emergencies, all people need clear, easy evacuation routes. If there is a large number of visitors, alternative routes that are less frequented are helpful. In bad weather, covered connecting roads are preferred. Adaptive systems can take such factors into account.
The legal framework for digital accessibility is constantly tightening. In the EU, the European Accessibility Act (EAA) requires barrier-free digital products and services from 2025. In Germany, the Barrier-Free Information Technology Ordinance (BITV) and the Disability Equality Act (BGG) apply.
The Web Content Accessibility Guidelines (WCAG) define specific technical standards for digital accessibility at three levels: A, AA and AAA. Level AA is the minimum legal standard in many jurisdictions. Navigation systems should see these standards not as a burden, but as a sign of quality.
Compliance is more than legal protection — it is good design for everyone. Barrier-free interfaces are often more intuitive, clear and user-friendly, even for people without restrictions. Universal design benefits everyone.
Barrier-free navigation should be built into systems right from the start, not grafted on later. People with disabilities are not marginalized — around 15 percent of the world's population lives with some form of disability, and temporary restrictions affect virtually everyone at some point.
Digital indoor navigation offers a unique opportunity to create true inclusion. The technology is there, the standards are defined, and the benefits are clear. Organizations that implement barrier-free navigation not only demonstrate legal compliance, but also social responsibility and user-centricity. Inclusive navigation is better navigation for everyone.
