Perception of a Spatial Implausibility Caused by Seamless Covert Teleportation
(2024)Proceedings of the 19th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications - Volume 1: GRAPP, HUCAPP and IVAPPThis paper explores human perception of spatial implausibility using seamless teleportation in circular and hexagonal closed-loop corridors. The impression of impossibility is generated by subtle teleporting the user within these corridors, thereby allowing them to unconsciously skip certain sections of them. Different levels of this ``impossibility’’ are presented by varying the percentage of skipping within these corridors, specifically ...Conference Paper -
Pointing, Pairing and Grouping Gesture Recognition in Virtual Reality
(2022)Lecture Notes in Computer Science ~ Computers Helping People with Special NeedsDuring a team discussion, participants frequently perform pointing, pairing, or grouping gestures on artifacts on a whiteboard. While the content of the whiteboard is accessible to the blind and visually impaired people, the referring deictic gestures are not. This paper thus introduces an improved algorithm to detect such gestures and to classify them. Since deictic gestures such as pointing, pairing and grouping are performed by sighted ...Conference Paper -
Automatic transcription of the Methods-Time Measurement MTM-1 motions in VR
(2024)Human Interaction and Emerging Technologies (IHIET-AI 2024): Artificial Intelligence and Future ApplicationsOur paper presents an approach to automatically detect and transcribe basic human motions in VR by means of the Methods-Time Measurement (MTM) system. MTM is a predetermined motion time system that consists of a list of predefined basic motions and the mean time values corresponding to those motions. This system is used to analyze manual workplaces. Currently, the MTM analysis is conducted manually. The working process that needs to be ...Conference Paper
