More and more people use their mobile phone while walking in order to call somebody, to browse the web, to read texts or for social networking. This leads to the problem that pedestrians are distracted from the main walking and navigation task which increases the likelihood of injury from stumbling more often and run into others or objects [18]. As this is an increasing problem, it should be analyzed how mobile user interfaces could be improved or adapted so that they reduce the time the user is engaged with them and the cognitive load while walking. A mobile user interface that adapts itself when the user is walking could also be considered as an important feature in the future, leading to a unique selling point for the first handsets supporting such a function effectively.
