| Abstract: | Objective: First, background research was conducted to identify key factors influencing tactile illusions and cross-modal perception. A prototype combining visual and vibrotactile stimuli was developed, including a vibrotactile sleeve synchronized with VR visuals through audio signals. User experiments were conducted to assess how visual input affected the perception of the CRE across six different timing intervals, with participants rating synchronization, illusion perception, and visual appeal. A pilot test refined the prototype and testing procedure. Results: The results suggest that the perception of the CRE can be influenced by visual stimuli. At slower timing intervals of the CRE the addition of a visual seems to enhance perception, at faster speeds, the visual disrupts the illusion. Participants preferred appealing visuals, although improvements to the arm visualization were recommended for enhanced realism. Conclusion: This research shows that visual input could influence the timing and perception of the CRE in VR. To improve on this research, future work should refine visual-tactile synchronization and explore other types of tactile feedback, as well as further analyze the relationship between timing and perception thresholds. |
