“…Our pilot study evaluated users' ability to perceive and discriminate different resistances in VR while using the prototype. Similar to previous haptic device research (Dominjon et al, 2005;Maereg et al, 2017;Suchoski et al, 2018;Ryu et al, 2020), we conducted a psychophysical experiment to measure the just noticeable difference (JND) of adaptive trigger resistance in VR. In addition, we also carried out semi-structured interviews to qualitatively assess subjective perception.…”

It is challenging to provide users with a haptic weight sensation of virtual objects in VR since current consumer VR controllers and software-based approaches such as pseudo-haptics cannot render appropriate haptic stimuli. To overcome these limitations, we developed a haptic VR controller named Triggermuscle that adjusts its trigger resistance according to the weight of a virtual object. Therefore, users need to adapt their index finger force to grab objects of different virtual weights. Dynamic and continuous adjustment is enabled by a spring mechanism inside the casing of an HTC Vive controller. In two user studies, we explored the effect on weight perception and found large differences between participants for sensing change in trigger resistance and thus for discriminating virtual weights. The variations were easily distinguished and associated with weight by some participants while others did not notice them at all. We discuss possible limitations, confounding factors, how to overcome them in future research and the pros and cons of this novel technology.

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.

“…While these devices aim to faithfully simulate the sensations of interacting with physical objects, other researchers have shown the efectiveness of sensory deception rooted in tactile illusions [23]. To this end, researchers present novel haptic devices that change the physical properties of a device to simulate tactile sensation of rigid objects [38], elastic objects [32], and liquids [33]. However, such systems are often fxed in size and shape.…”
