Dynamic Redirection for VR Haptics with a Handheld Stick.

Area of Science:

• Human-Computer Interaction
• Virtual Reality
• Haptics

Background:

• Virtual reality (VR) systems often lack realistic haptic feedback for object interaction.
• Simulating complex shapes and textures in VR remains a significant challenge.
• Existing methods struggle to provide intuitive and accurate tactile experiences for users.

Purpose of the Study:

• To propose and evaluate a general handheld stick haptic redirection method.
• To enable users to experience complex virtual shapes through physical interaction.
• To enhance immersion and realism in virtual environments via tactile feedback.

Main Methods:

• Developed a haptic redirection technique for a handheld stick.
• Continuously updated virtual and physical contact points during user interaction.
• Applied redirection to the virtual stick and/or the user's hand.
• Conducted a user study with 26 participants.

Main Results:

• Offset detection thresholds were found to be within [-15cm, +15cm].
• Participants achieved 78% accuracy in identifying invisible virtual objects using the method.
• The method proved effective for both tapping and contour tracing interactions.

Conclusions:

• The proposed haptic redirection method significantly improves the ability to perceive virtual object shapes.
• This technique offers a promising approach for creating more immersive and interactive VR experiences.
• Further research can explore applications in various fields requiring realistic tactile feedback.
