Viability of In-vehicle Displays To Replace or Supplement Variable Message Signs (VMS) - by Soon Hui Yee (2013)

This project is a study on the viability of the in-vehicle display (IVD) to replace or supplement Variable Message Signs (VMS) which are used for traffic information and routing by road authorties. The limitations and benefits of these methods were studied followed by an extensive user study in a driving simulation environment under 3 conditions. The evaluation was conducted using eye-tracking, questionnaires and interview.


Cognitive Impact of Tablet-based POI Search Tools on Driving and Information Search Performance - by Lamiaa Chaabi (2012)

The overall objective of this project was to compare the cognitive impact of navigation point of interest (POI) search approaches. 25 participants executed two POI searches on two different map-based applications, Google Map and Info Explorer, while driving in a simulation environment. Their eye gaze behaviour, total task time (TTT) and driving performance, as well as qualitative measures (e.g. interviews and questionnaires), were used to quantify the cognitive impact of the usage of each POI tool.

Communal Navigation for London Pedestrians - by Desislava Hristova (2011) 

The project investigated the needs of Londoners in terms of pedestrian navigation, and informed by these requirements - a pedestrian navigation ecosystem comprising of a mobile application for navigation and a route recommender was designed and implemented. A user study comprising of user trials on UCL campus coupled with questionnaires and interviews concluded that such an application was of great value to share local knowledge and led to interesting findings about trust, sharing and interaction.

Change Blindness on Mobile Devices - by Thomas Davies (2011)

This project investigated the occurance of change blindess and inattention blindness on mobile devices. Two mobile applications were developed and user studies were conducted. The following is an abstract from the CHI 2012 paper (refer to publications page) that resulted from this excellent piece of work and earned him a trip to Austin, TX. 

"Insights into human visual attention have benefited many areas of computing, but perhaps most significantly visualisation and UI design [3]. With the proliferation of mobile devices capable of supporting significantly complex applications on small screens, demands on mobile UI design and the user’s visual system are becoming greater. In this paper, we report results from an empirical study of human visual attention, specifically the Change Blindness phenomenon, on handheld mobile devices and its impact on mobile UI design. It is arguable that due to the small size of the screen - unlike a typical computer monitor - a greater visual coverage of the mobile device is possible, and that these phenomena may occur less frequently during the use of the device, or even that they may not occur at all. Our study shows otherwise.

We tested for Change Blindness (CB) and Inattentional Blindness (IB) in a single-modal, mobile context and attempted to establish factors in the application interface design that induce and/or reduce their occurrences. The results show that both CB and IB can and do occur while using mobile devices. The results also suggest that the number of separate attendable items on-screen is directly proportional to rates of CB. Newly inserted objects were correctly identified more often than changes applied to existing on-screen objects. These results suggest that it is important for mobile UI designers to take these aspects of visual attention into account when designing mobile applications that attempt to deliver information through visual changes or notifications."
