Abstract: This paper investigates human perception of spatial implausibility through seamless teleportation in circular and hexagonal closed-loop corridors. Spatial implausibility refers to virtual spaces that deviate from Newtonian Euclidean geometry rules, while seamless teleportation involves changing the user’s position in the virtual world without their awareness. In this work, the impression of implausibility is generated by subtle teleportation of the user within these corridors, thereby allowing them to unconsciously skip certain sections of them. Different levels of this “implausibility” are presented by varying the percentage of skipping within these corridors, specifically 0%, 15%, and 30% of the corridor’s overall length. These implausibilities are assessed through a within-subject study on naive participants to determine their perception of spatial implausibility. Our findings indicate no significant difference in the detection rates between the two corridor shapes. Interestingly, most participants interpreted the manipulation as a change in the environment’s shape or size while only few could perceive the teleportation and the skip. This paves the way for future research to leverage this technique for subtle spatial manipulation. (More)
