A very apparent drawback of mobile devices is that their screens do not allow for the display of large amounts of information at once without requiring interaction, which limits the possibilities for information access and manipulation on the go. Attaching a large external display can help a mobile device user view more content at once. We report on a study investigating how different configurations of input and output across displays affect task performance, subjective workload and preferences in map, text and photo search tasks. After conducting a detailed analysis of the performance differences across different UI configurations, we provide recommendations for the design of distributed user interfaces.
Umer Rashid has conducted my PhD research under the supervision of Prof. Aaron Quigley in the School of Computer Science at University of St Andrews. The goal of his research is to look into the ways mobile interaction with external large displays can complement the inherent capabilities of each device, thus resulting into an enhanced user experience.
