AI Summary

Whether higher visual and physical realism in VR hand interaction inherently improves user experience remains empirically unresolved. Method: This study conducts the first systematic comparison of three dominant hand-interaction paradigms—Attachment, Penetration, and Torque—through controlled user experiments across basic manipulation and high-precision tasks. A multidimensional evaluation framework is established, integrating technical implementation fidelity, task performance metrics, subjective immersion (e.g., presence), and cognitive load (e.g., NASA-TLX). Contribution/Results: Attachment achieves optimal overall performance in practical, commercially viable scenarios. While Penetration and Torque offer superior physical plausibility, their advantages are confined to specific high-precision tasks and often incur increased operational and cognitive load. The findings reveal a significant trade-off between realism and usability, leading to a pragmatic interaction-selection guideline. Crucially, the study validates “appropriate realism”—a balanced optimization among physical fidelity, usability, and user satisfaction—as the optimal design principle for VR hand interaction.

Abstract

In virtual reality (VR), it is widely assumed that increased realism in hand-object interactions enhances user immersion and overall experience. However, recent studies challenge this assumption, suggesting that faithfully replicating real-world physics and visuals is not always necessary for improved usability or immersion. This has led to ambiguity for developers when choosing optimal hand interaction methods for different applications. Currently, there is a lack of comprehensive research to resolve this issue. This study aims to fill this gap by evaluating three contemporary VR hand interaction methods—Attachment, Penetration, and Torque—across two distinct task scenarios: simple manipulation tasks and more complex, precision-driven tasks. By examining key technical features, we identify the strengths and limitations of each method and propose development guidelines for future advancements. Our findings reveal that while Attachment, with its simplified control mechanisms, is well-suited for commercial applications, Penetration and Torque show promise for next-generation interactions. The insights gained from our study provide practical guidance for developers and researchers seeking to balance realism, usability, and user satisfaction in VR environments.
