Two-Handed Click and Tap: Expanding Input Vocabulary of Controllers for Virtual Reality Interaction.

Area of Science:

• Human-Computer Interaction
• Virtual Reality

Background:

• Virtual reality (VR) interactions often rely on complex controller inputs.
• Exploring efficient two-handed input methods is crucial for enhancing VR user experience.

Purpose of the Study:

• To investigate the design space of two-handed input using controller touchpads in VR.
• To identify and evaluate user performance of thumb-based tapping and clicking operations for VR interaction.

Main Methods:

• Conducted four experiments to analyze user performance on two-handed operations.
• Evaluated interaction characteristics including completion time, accuracy, and user feedback.
• Developed and tested a novel command-input technique based on identified operations.

Main Results:

• Identified 14 potentially usable two-handed operations for VR.
• User performance analysis provided insights into interaction characteristics.
• The proposed command-input technique demonstrated competitive performance against traditional menus in VR text entry.

Conclusions:

• Two-handed thumb-based touchpad input offers a viable design space for VR interactions.
• The developed technique shows potential for efficient command input in VR.
• This research contributes to designing more intuitive and effective VR controller interactions.
