“…Hirano et al [6] have notably superimposed textures associated with different levels of hardness on a real object, successfully influencing the perception of hardness of this object. Similar methods have been proposed to influence a "softness" perception [17] or the perceived weight of an object ( [5]. In a purely AR context, Jeon and Choi [7] have also shown how adding a force-feedback during interaction with a real object could modulate the stiffness perceived by the user.…”

Does it feel the same when you touch an object in Augmented Reality (AR) or in Virtual Reality (VR)? In this paper we study and compare the haptic perception of stiffness of a virtual object in two situations: (1) a purely virtual environment versus (2) a real and augmented environment. We have designed an experimental setup based on a Microsoft HoloLens and a haptic force-feedback device, enabling to press a virtual piston, and compare its stiffness successively in either Augmented Reality (the virtual piston is surrounded by several real objects all located inside a cardboard box) or in Virtual Reality (the same virtual piston is displayed in a fully virtual scene composed of the same other objects). We have conducted a psychophysical experiment with 12 participants. Our results show a surprising bias in perception between the two conditions. The virtual piston is on average perceived stiffer in the VR condition compared to the AR condition. For instance, when the piston had the same stiffness in AR and VR, participants would select the VR piston as the stiffer one in 60% of cases. This suggests a psychological effect as if objects in AR would feel "softer" than in pure VR. Taken together, our results open new perspectives on perception in AR versus VR, and pave the way to future studies aiming at characterizing potential perceptual biases.

“…In mixed reality, some researchers have proposed to render different virtual object shapes on real objects. Even if the weight of the real object does not change, the rendered virtual object can give the user the illusion of a change in the center of gravity [65].…”

Virtual reality (VR) technology can provide users with an immersive experience as if they are in the real world, which can be applied in the fields of entertainment, education and scientific research, etc. In order to improve the sense of presence and immersion in VR, the design of multimodal feedback is an important component. In particular, the simulation of weight of virtual objects poses many challenges due to the limitations of hardware and software. Many researchers focused on this issue in various ways. These methods are mainly divided into two categories: device-based simulation and software-based simulation. This paper investigates the focus of software-based simulation, particularly for the virtual feedback methods proposed by researchers in recent years. We introduce the background of these proposed methods, technical implementation principles, application scenarios, the advantages and disadvantages of these simulation methods, and the evaluation criteria. We also propose the future challenges and the development of simulation methods for weight perception of virtual objects in VR.

“…It states that when holding objects of the same weight but different size, the bigger object is perceived to be lighter than expected. R-V Dynamics [4] created an illusion that changes weight perception of a real object. They superimposed computer-generated imagery (CGI) representing inertial force of movable objects in an AR environment.…”
