Mobile interaction does not exist
Joe Marshall, Paul Tennent · 2013
Most mobile systems are 'stop-to-interact'; designed for active interaction only when a user is standing still, paying visual and mental attention to the device. However, people are increasingly carrying and using devices while undertaking a wide range of movement activities, such as walking, cycling, running. Some existing systems such as Apple's Siri aim for hands and eyes free use, but they do not consider the wider challenges of interaction during movement.
