Touchscreens offer a wide range of functions in a very small space. At the same time, they can become a barrier for example, when people with visual or motor impairments cannot interact primarily through sight or when operation requires quick, unambiguous feedback.
The production of digital interfaces is also part of the equation: Displays require rare earth elements, metals and complex composite materials. Their extraction and processing take a toll on the environment and people. At the same time, many components are difficult to recycle.
