Reconciling Reduced the Sense of Ownership and Agency toward a Virtual Keypad with Enhanced Haptic Experience Using
IEEE Transactions on Haptics
|July 6, 2026
Summary
Self-Haptics uses the body for tactile feedback. "(Not My) Self-Haptics" enhances virtual object realism by manipulating visual cues, though it may decrease task performance and agency.
Area of Science:
- Human-Computer Interaction
- Virtual Reality
- Haptic Feedback
Background:
- Self-Haptics enables tactile sensations using the user's own body as a prop for virtual interactions.
- Maintaining user's sense of ownership (SoO) and agency (SoA) with virtual objects in Self-Haptics, aligned with visual cues, remains a challenge.
Purpose of the Study:
- To introduce and evaluate the concept of "(Not My) Self-Haptics" for resolving inconsistencies in Self-Haptics.
- To investigate the impact of visual manipulation on user experience (SoO, SoA) and task performance with a virtual keypad (VPad).
Main Methods:
- Users interacted with a virtual keypad (VPad) aligned or misaligned with their real hand (RHand).
- Tactile feedback was provided via Self-Haptics during VPad interaction.
- User experience and task performance were measured, alongside the Haptic Experience Inventory.
Main Results:
- Misaligned or hidden virtual hands significantly reduced SoO and SoA towards the VPad.
- Self-Haptics tactile feedback decreased task performance but increased SoO for VPad interactions near the virtual hand.
- Visual modifications enhanced Autotelics, Involvement, and Realism compared to mid-air interactions.
Conclusions:
- Visual cues critically influence SoO and SoA in Self-Haptics, with misalignment reducing these perceptions.
- While Self-Haptics can decrease task performance, it improves subjective experiences like realism and involvement.
- "(Not My) Self-Haptics" presents a viable method for enhancing virtual interaction realism, balancing perceptual and performance trade-offs.

01:14Design Example: Resistive Touchscreen
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

01:27Tactile and Chemical Senses
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...
