Evaluating Remapped Physical Reach for Hand Interactions with Passive Haptics in Virtual Reality

Area of Science:

• Human-Computer Interaction
• Virtual Reality
• Robotics

Background:

• Virtual reality (VR) systems often use motion tracking for object selection and manipulation.
• Aligning physical objects with virtual counterparts enhances realism and tactile feedback.
• Perfect physical-virtual object alignment is challenging without custom environments.

Purpose of the Study:

• To investigate methods for mapping one physical object to multiple virtual objects at different locations.
• To evaluate techniques for offsetting virtual hand positions relative to physical hand movements.
• To assess the impact of these remapping techniques on user experience and adaptability.

Main Methods:

• Studied two hand remapping techniques: static translational offset and dynamic interpolation.
• Conducted experiments to measure reaching effectiveness, comfort, and adaptation to mismatches.
• Developed a case study for an immersive game application to demonstrate usability.

Main Results:

• The static translational offset technique outperformed the dynamic interpolation method.
• The translational technique demonstrated greater robustness with larger physical-virtual location mismatches.
• User adaptation and comfort varied between the two remapping approaches.

Conclusions:

• Hand remapping in VR can enhance interaction realism and usability.
• Static translational offset is a promising technique for managing physical-virtual object mismatches.
• Further research can optimize VR interaction through advanced hand remapping strategies.
