Saga, Satoshi, and Kotaro Sakae. “Sensory Perception During Partial Pseudo-Haptics Applied to Adjacent Fingers.” Multimodal Technologies and Interaction 9, no. 3 (March 2025): 19. https://doi.org/10.3390/mti9030019.

This research explores how manipulating visual feedback to create "pseudo-haptic" sensations changes when applied selectively to adjacent fingers. Key findings include:

• Finger Contact Matters: The strength of the illusion is affected by how adjacent fingers are touching.
• Movement Enhances Illusion: Dynamic movements create a stronger illusion than quasi-static movements.
• Inhibited Fingers Feel Discomfort: Regardless of which finger gets the altered visual feedback, the finger that is restricted or inhibited in its movement is the one that experiences discomfort.

This study examined the influence of adjacent body part interactions, demonstrating that partial pseudo-haptic sensations can be more complex and that the discomfort produced is related to the inhibition of movement. This provides important insights for designing displays using Pseudo-Haptics.
