Title: Studying the impact of using different sized devices when resuming work involving 3D models.

Examining Committee:

Dr. Derek Reilly - Faculty of Computer Science (Supervisor)

Abstract:

The use of different sized devices in personal and professional settings may impact how tasks are performed and resumed on these devices. We present results from a controlled experiment measuring the effect of using different sized displays when conducting tasks involving 3D models. Today, sophisticated 3D graphics can be presented on touch enabled screens of widely varying sizes and form factors. However, the choice of device to use, for example in professional settings like a manufacturing plant, is highly sensitive to factors including mobility and physical surroundings. The purpose of this study is to explore how screen size impacts task performance involving touch interaction with 3D models, and how transitioning from one sized display to another impacts task resumption. Performance was significantly better when tasks were resumed on same sized devices. Within different sized devices, performance was comparatively better while moving from small to large sized devices than vice versa. We also present the strategies employed by participants to finish the tasks, as well as design specifications for using 3D models on same and different sized devices.
