Comparing Motion-based Versus Controller-based Pseudo-haptic Weight Sensations in VR

Abstract

This work examines whether pseudo-haptic experiences can be achieved using a game controller without motion tracking. For this purpose, we implemented a virtual hand manipulation method that uses the controller's analog stick. We compared the method's pseudo-haptic experience to that of the conventional approach of using a hand-held motion controller. The results suggest that our analog stick manipulation can present pseudo-weight sensations in a similar way to the conventional approach. This means that interaction designers and users can also choose to utilize analog stick manipulation for pseudo-haptic experiences, as an alternative to motion controllers.

A Systematic Review of Weight Perception in Virtual Reality: Techniques, Challenges, and Road Ahead

“…C/D ratio [7], [115], [126] [137]- [145] Includes approaches that adjusting the translation and rotation displacement of the object, or the movement offset between virtual hand and actual hand to create an illusion of weight perception Velocity [128], [138], [142], [146]- [149] Includes approaches that alter the moving speed of the object/hand to create the illusion of weight…”

“…One of the commonly used pseudo-haptic techniques in weight perception is to modulate the mapping between the actions of the user and the feedback provided by the system by altering the control/display ratio, by changing the amount of movement between virtual and actual hand or the displacement of the object to generate different weight illusion. The technique was applied in the research works of Dominjon et al [144], Rietzler et al [7], Samad et al [145], Taima et al [143], Hirao et al [142], and Paul et al [140].…”

“…The findings confirmed that the delay parameter compared to the changing of C/D ratio could present a higher level of sense of weight. Further research was conducted by Hirao et al to compare the weight sensation in VR by using a motion-based versus controller-based method [142] while dragging the object. In the experiments, Participants were required to pull the handle of a virtual box by motion-based manipulation (extend the hand to grab the handle and pull it towards their body), and by controller-based manipulation (tilt the controller's analog stick to control the virtual hand movement without moving the actual hand).…”

VibroWeight: Simulating Weight and Center of Gravity Changes of Objects in Virtual Reality for Enhanced Realism

“…Not sensing weight properties could negatively impact the sense of presence, primarily due to the absence of muscle stress [4]. Researchers have proposed several solutions to leverage vibrations and pseudo-haptic to emulate the weight of virtual objects [5]- [7]. However, neither simple vibration feedback nor pseudo-haptic approaches can sufficiently simulate the weight properties of virtual objects with the necessary level of accuracy and realism.…”

“…。近 年来在虚拟现实环境中广泛引起人们关注的伪触 觉反馈技术(Pesudo-Haptic Feedback Techniques) (Aoyama et al, 2016;Bi et al, 2018;Kawabe, 2020;Samad et al, 2019)或许源自于多感官错觉这一理 论基础。伪触觉反馈技术由 Lécuyer 等人(2000) 提出, 其是一种不依赖于触觉反馈, 而通过跨感 觉通道(Crossmodal)信息来呈现触觉感知的技术 (Kang & Lee, 2018;Ujitoko et al, 2019b)。在电脑 界面或虚拟现实环境中, 可以通过伪触觉反馈技 术灵活改变虚拟物体的视觉显示, 从而模拟物体 的重量 (Bi et al, 2018;Hirao et al, 2020;Samad et al, 2019)、硬度 (Kawabe, 2020;Li et al, 2016; 第 3 期 万必成 等: "有声有色"的触觉体验：来自多感觉通道整合的线索 581 Matsumoto et al, 2016)和粗糙度 (Ota et al, 2020;Sato et al, 2020;Ujitoko et al, 2019a)等触觉感知。 基于多感官错觉的伪触觉反馈技术允许用户更自 由的交互, 并且规避了如设备使用疲劳, 硬件时 间和空间分辨率低等问题 (Hirao et al, 2020)。该 (Hashimoto et al, 2018;Ramírez et al, 2018) 感知就会受到听觉线索的影响 (Etzi et al, 2018;Guest et al, 2002;Kim et al, 2007;Lederman, 1979;Jousmäki & Hari, 1998)…”
