Subjective Evaluation for 2D Visualization of Data from a 3D Laser Sensor

The purpose of this study was to increase understanding of how information from a 3D sensor should be presented in two dimensions for users. Stimuli consisted of video footage where people moved in different patterns and carried out various activities. Seven visualizations were used in a simple-and a complex scene respectively. The subjective ratings and interviews shows that various visualizations highlight different parts of the scene and allow the user to prioritize different information. This means that the choice of display must be connected to the application. In future research these results will be supplemented with objective performance metrics, e.g. response time to detect targets and eye movements. Also, to understand end-users and increase their performance in real settings further task analysis will be conducted.
