If the buttons follow how people actually tap, is the app easier?
Many apps keep the layout fixed, which can confuse beginners. This study asks if moving the buttons to match how people actually tap makes it easier to find the next step.
What they did
They built a prototype and had a few people perform a task. The adaptive layout was compared to the static one, and the numbers came from the test.
What they found
Users finished the task faster and with fewer detours on the adaptive layout. The exact numbers are in the source.
