“…Studies that have employed action tasks such as reaching or grasping with real objects have found that with neutral objects, binocular cues dominate performance [ 99 ], while those using familiar objects have found influences of familiar size [ 100 ]. Studies with reaching towards virtual objects have found contributions of both binocular vision and familiar size affect distance perception [ 101 , 102 ]. Moreover, the contribution of stereopsis was stronger when participants reached with their eyes open versus eyes closed after object presentation, whereas the contribution of familiar size was stronger during reaching with eyes closed versus open [ 101 , 102 ].…”

Ideally, future studies of the accuracy of size and distance processing for action tasks in VR will be more tailored to the tasks typically performed in VR (e.g.…”

The promise of virtual reality (VR) as a tool for perceptual and cognitive research rests on the assumption that perception in virtual environments generalizes to the real world. Here, we conducted two experiments to compare size and distance perception between VR and physical reality (Maltz et al . 2021 J. Vis. 21 , 1–18). In experiment 1, we used VR to present dice and Rubik's cubes at their typical sizes or reversed sizes at distances that maintained a constant visual angle. After viewing the stimuli binocularly (to provide vergence and disparity information) or monocularly, participants manually estimated perceived size and distance. Unlike physical reality, where participants relied less on familiar size and more on presented size during binocular versus monocular viewing, in VR participants relied heavily on familiar size regardless of the availability of binocular cues. In experiment 2, we demonstrated that the effects in VR generalized to other stimuli and to a higher quality VR headset. These results suggest that the use of binocular cues and familiar size differs substantially between virtual and physical reality. A deeper understanding of perceptual differences is necessary before assuming that research outcomes from VR will generalize to the real world. This article is part of a discussion meeting issue ‘New approaches to 3D vision’.

“…Interesting work has been done before in the field of depth perception in virtual reality environments, which involved demonstration of visual feedback value when reaching a virtual object [12]. The role of a familiar dimension of the object the user was offered to reach was also examined when tackling the same task [15]. Apart from that, [15] shows that a task is better fulfilled if the object that the user is offered to reach is specific, not an abstract one.…”

Apart from that, [15] shows that a task is better fulfilled if the object that the user is offered to reach is specific, not an abstract one. Although an abstract object rather means a 'simple box', while in visualization systems, this typically refers to complex structured objects with high semantic charge.…”

The paper examines research methods in the field of computer visualization based on virtual reality. Virtual reality environments were initially used for training simulation, but as far back as in the late 1980s scientific visualization systems based on virtual reality occurred. Those were the pilot versions of virtual test stands that were used in developing reusable space shuttles. Currently, virtual reality environments have been actively used in scientific visualization and software visualization systems. Developing such systems involves not only the issues of software implementation, modelling or adequate equipment choice, but also the tasks connected with cognitive processes occurring in both users and developers of visualization systems. Featured is a brief review of papers dealing with research in human interaction with virtual reality. The scope of tasks in developing visualization systems based on virtual reality is determined. The conclusion discusses several research issues, the solutions to which will increase the efficiency of interaction of users with virtual environments.
