1. 6. Moving Beyond Two Dimensions : An Evaluation of Four Different Three-Dimensional Locomotion Interfaces for Virtual Reality

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Erik Meurk; [2023]
   Keywords : virtual reality; locomotion; three dimensional; virtuell verklighet; rörelse; tre dimensioner;

   Abstract : This paper presents a comparative evaluation of four 3D locomotion interfaces in virtual reality: Slider, Teleport, Point & Tug, and Arm-Cycle. The study employed a mixed methods approach to assess their performance using a token-collecting task in a virtual environment with obstacles, focusing on efficiency, spatial awareness, usability, task load, presence, and cybersickness.

3. 7. Effects of Virtual Reality and Trajectory Visualization on Neurosurgical Training

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Max Wippich; [2023]
   Keywords : Virtual reality; Trajectory visualization; Neurosurgical education; External Ventricular Drain Placement; Virtuell verklighet; Banvisualisering; Neurokirurgisk utbildning; Externt ventrikulär dräneringsplacering;

   Abstract : With its increasing potential, Virtual Reality (VR) technology has found a growing presence in medical education. In the domain of neurosurgical training, VR has been thoroughly investigated, but gaps still persist, such as in the field of Minimally Invasive Surgery (MIS) and assistive visualizations. READ MORE

4. 8. An Evaluative Study on the Impact of Immersion and Presence for Flight Simulators in XR

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Robin Dahlkvist; [2023]
   Keywords : Extended reality; Mixed reality; Immersion; Presence; Simulator sickness; Extended reality; Mixed reality; Immersion; Närvaro; Simulatorsjuka;

   Abstract : Flight simulators are a central training method for pilots and with the advances of human-computer interaction, new cutting-edge technology introduces a new type of simulator using extended reality (XR). XR is an umbrella term for many representative forms of realities, where physical reality (PR) and virtual reality (VR) are the endpoints of this spectrum, and any reality in between can be seen as mixed reality (MR).

5. 9. Similarity metric for crowd trajectory evaluation on a per-agent basis : An approach based on the sum of absolute differences

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Karl Brunnberg; [2023]
   Keywords : Crowd Simulation; Trajectory; Similarity Metric; Virtual Agents; Crowd Perception; Folkmassasimulering; Färdväg; Likhetsmetrik; Virtuella Agenter; Folkmassaperception;

   Abstract : Simulation models that replicate realistic crowd behaviours and dynamics are of great societal use in a variety of fields of research and entertainment. In order to evaluate the accuracy of such models there is a demand for metrics and evaluation solutions that measure how well they simulate the dynamics of real crowds. READ MORE

6. 10. Investigation on Enhancing Fire Threat Perception in Virtual Reality through Subject-Expectancy Effect

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Hsuan-Ting Liu; [2023]
   Keywords : Virtual reality; safe distance; subject-expectancy effect; thermal radiation; placebo effect; fire scenario.; Technology and Engineering;

   Abstract : This thesis examines the use of subject-expectancy effect on enhancing fire threat perception in virtual reality. The study involves a virtual fire scenario design and 33 participants who experience virtual fires of three different scales in the scenario using a head-mounted display as visual and auditory perception and adopting physical movement in real world as their way of locomotion.
