1. Travel in an Immersive 1:1 Virtual Environment

    3DUI implemented in Unity3D utilizing Kinect for skeletal tracking and a Sony HMD combined with an InertiaCube for head rotation. The Sony HMD and InertiaCube is intended to be replaced by the Ocelus Rift in future work, if any. A big improvement to both the interaction techniques implemented and the user experience is anticipated to be achieved by utilizing two depth camera tracking devices e.g. Kinect for 360 tracking. The research compares two travel methods, pointing based travel velocity with and without real walking, in order to determine if real walking adds effectiveness and efficiency to pointing based travel velocity. An experiment was conducted which measured 19 participants completion time, errors, and position of errors in a virtual environment. 7 were not able to complete the test due to severe simulator sickness, and were excluded in the results. The difference in neither time nor error is statistically significant. Thus the results show no significant evidence that real walking improves the performance when combined with pointing based travel velocity technique. However, several aspects need to be taken into consideration. 1) The user could only walk within a small tracking space. 2) The user had to face the body in the same direction all the time, which made it necessary for a rotation technique that seems to cause an increase in symptoms related to simulator sickness. Project role and responsibility: Analysis of interaction techniques for travel, navigation and wayfinding in 3DUI, Analysis of spatial experience, learning and knowledge, reference frames, manual control, Experiment design, interaction design, test VE design and implementation. Project involvement: Kinect implementation, general Unity3D implementation
