9. 9 related work Attention theory Designing seamless displays for interaction in motion... Smart attention workshop MobileHCI '15 Single channel processing Attention can be focused on one single task at a time as if the task occupies the single channel of human cognition e.g. reading a newspaper and a computer display Automaticity theory Assumes we can automate certain tasks for which attention is not required e.g. walking and talking driving (lane keeping) and listening to radio [Wickens, 2013]
