On Monday, March 18th, Google Doodle featured the Japanese inventor of detectable dome tiles, Seiichi Miyake. His invention changed the world by empowering and protecting individuals with visual impairments to cross streets with greater ease. Fifty-two years have passed since the first dome tiles were installed, and these detectable warning tiles are now part of many cities throughout the world.

Cities offer a wealth of opportunities, both in terms of jobs and accessibility. However, some of those same cities don’t have easily accessible sidewalks, transportation, or office buildings. Although there have been great improvements in accessibility, some cities still have many steps they can take to be more livable and convenient. With the creation of the Americans with Disabilities Act (ADA), many cities are obligated to add detectable warning tiles to their sidewalks and curb cutouts.

The Americans with Disabilities Act (ADA) expects workplaces and public areas to be accessible for people with disabilities. Since 1990, businesses and communities strive to meet these requirements. For example, public areas must take steps to remove barriers and add domed-tile curb ramps to improve accessibility and safety for people with impairments.

The Americans with Disabilities Act (ADA) sets a number of standards to govern curb ramps and to determine wheelchair accessibility. Curbs create an increased likelihood of injury or accidents for people who use a wheelchair or walker. For a person with a disability, curbs without a ramp could become unusable and be considered discriminatory.
