Stein a. d. Traun. One glance at the gym floor is enough: colorful lines crisscross in every direction. For many, this is confusing; for some, it’s a real barrier.
When you walk into a traditional sports hall, you’re usually met with a complex web of red, blue, green, and white lines. But especially in fast-paced sports, it’s easy to lose your bearings and end up looking at the wrong line. What’s mostly just a visual annoyance for people without disabilities—and the reason for the occasional point loss—is an insurmountable barrier for others.
People with visual impairments, cognitive limitations, or declining perceptual abilities not only lose their bearings in this tangle of lines but often also lose access to the game. While athletes prioritize the athletic and inclusive benefits, municipalities and sports facility operators are primarily concerned with economic and functional aspects. Dedicated facilities for each individual sport would be the ideal solution, but in times of tight budgets, this is not only unrealistic but also unsustainable.
A technological innovation from the Bavarian manufacturer ASB GlassFloor demonstrates how modern sports facilities can be designed to be accessible and inclusive. The ASB GlassFloor replaces traditional, permanently painted floor markings with an LED playing field system. The lines are formed by LEDs located beneath a surface of tempered safety glass and are controlled via a touchscreen. When basketball is being played, only the basketball lines light up. If the activity switches to volleyball or badminton, the old lines disappear completely and a new playing field appears. Since the LED lines can be freely configured according to customer preferences, playing field sizes and markings can be flexibly adapted to the needs of various sports.
A single playing surface free of distracting visual stimuli greatly enhances athletes’ ability to concentrate and improves their safety. The surface’s texture also plays a crucial role in accessibility. The durable material—glass—is highly elastic and slip-resistant. Ceramic dots fused into the surface provide traction that, according to the manufacturer, surpasses that of conventional floors. Between the ceramic dots are tiny air cushions designed to prevent friction burns in the event of a fall. The manufacturer also emphasizes that the floor’s high elasticity is gentle on athletes’ joints.
At the same time, wheelchairs have good traction for quick changes in direction and braking maneuvers without damaging the floor or leaving permanent marks. Since the glass surface is durable and resistant to street shoes, liquids, and heavy loads, the hall can easily be used for non-athletic events. The LED lines can be completely turned off for such occasions. With a life expectancy of around 70 years, as projected by the manufacturer, and low maintenance requirements compared to wood—since regular sanding and resealing are not necessary—the system is considered a long-term investment.
The University of Oxford and the high-tech OYM sports center in Switzerland are already using the system to create optimal conditions for professional sports. As the first major renovation project, the Untermainhalle was equipped with the innovative floor three years ago. The traditional handball club TV Großwallstadt has been playing on the glass sports floor ever since. But the potential for recreational sports is also considerable. In Saarlouis, the Stadtgartenhalle, which opened in 1968, is being fitted with a state-of-the-art LED glass floor. The district of Cuxhaven is also setting new standards in terms of multifunctionality and accessibility with the innovative flooring in the newly built Cuxlandhalle, which seats 1,200 spectators. When municipalities consistently prioritize accessibility during renovations or new construction, digital glass floors offer a valuable opportunity. They transform the sports hall into a space that is equally safe and intuitive for everyone to use.
