Linking visual perception and interactive tasks on wall displays

Advisors: Anastasia Bezerianos and Olivier Chapuis

Presentation slides

Wall-displays are particularly well adapted for multi-user collaboration. Nevertheless, when working together, people can place themselves at different positions and have a different point of view of the data. Moreover, they may occlude part of the display making it inaccessible to other people in the room.

The internship will be an introduction to research in Human Computer Interaction (HCI) and Visualization, focusing on issues related to visual perception (e.g., legibility, visual distortion and human occlusion) when interacting in front of a wall-sized display.

The student will work on associating visual perception features to interactive tasks (e.g., view angle vs direct/indirect pointing, and human occlusion and object dragging), and will implement a simple prototype to illustrate these associations. Finally, the student will learn about HCI evaluation methods and, ideally, will conduct an experiment (with human subjects) to test and quantify the developed association.
