Additionally, our results also strengthen the value of fully immersive setups which, today, are accessible for a variety of applications due to the widely available consumer hmds. This article contributes to the development of effective spatial compression methods by utilizing the break of immersion as a benchmark for redirection techniques. Effect of virtual human gaze behaviour during an orthogonal collision avoidance walking task sean lynch, julien pettr, julien bruneau, richard kulpa, armel cretual, anne-hélène olivier abstract a study performed in virtual reality on the effect of gaze during collision avoidance between two walkers.

Both approaches were tested at two high schools using a vr environment that teaches students about solar energy production via tours of a solar plant. A moving passive obstacle crossed the participants trajectory perpendicularly at various pre-defined risks of collision distances. However, the occurrence of cybersickness is a particular problem in this application that will need to be addressed.

The appearance of the marker is designed such that the marker is detected by infrared cameras even when printed on a non-planar surface while its appearance can be diminished by the projection to be as imperceptible as possible to human observers. The approach uses a stereo camera attached to an hmd to provide the illusions of virtual body ownership and spatial presence in vr. While many experiences use a single camera viewpoint, an increasing number of experiences use multiple camera locations.

We find that in-air is faster than smartwatch (p). We present a new modeling for this problem, accounting for the two factors whose interplay determine the impact on the overall task performance the difference in errors introduced by performing dimensionality reduction to 2d or 3d, and the difference in human perception errors under different visualization conditions. Our proposed technique is consistent with the established rst mapping (rotation, scaling, translation) for 2d multitouch input and follows suggestions from prior work on multitouch 3d interaction.

Finally, we demonstrate the potential of our technique to enable on-world touch interactions through 5 example applications. Arguably, an exocentric view would afford a better overview and, thus, more intuitive flight control of the drone. There are, however, some barriers to adoption that must be addressed, such as that of motion sickness which can lead to undesirable symptoms including postural instability, headaches, and nausea.

This technique achieves high frame rates (30fps) with minimum foreground cut-off and temporal jittering artifacts. Participants touched visual targets on four corresponding physical-visual representations of a human head. Vr enables new capabilities, impossible in the real world, such as an unobstructed view of the keyboard, without occlusion by the users physical hands. Its dynamic size depends on numerous factors and its violation evokes discomfort. We discuss vls validity, relation to presence, and how it may inform vr development and application.

    The core of our system is an online video-based assembly parsing method that can understand the assembly process. This research explores the degree to which animation fidelity affects users gaze behavior during interactions with virtual reality training simulations that include virtual human. Edward swan abstract for optical see-through head-mounted displays, the mismatch between the displays focal length and the observed scene inadvertently prevents users from simultaneously focusing on the presented computer graphics and the scene, leading to eye strain as users refocus between the two. Participants had to complete a multi-directional pointing task in which the visual feedback of the tapping finger could be deviated in order to increase or decrease the motor size of a target relative to its visual size. These findings provide more insight into ps in virtual environments.

    Contrary to intuition, we show that rapid movement speeds reduce players feelings of motion sickness as compared to continuous movement at normal walking speeds. Fabricating diminishable visual markers for geometric registration in projection mapping abstract we propose a visual marker embedding method for the pose estimation of a projection surface to correctly map projected images onto the surface. Immersive visualization of abstract information an evaluation on dimensionally-reduced data scatterplots abstract in this work, we evaluate the use of an hmd-based environment for the exploration of multidimensional data, represented in 3d scatterplots as a result of dimensionality reduction (dr). The studies quantified the bandwidth savings achievable by the proposed approach and characterize the relationships between quality of experience (qoe) and network latency. Instead, we propose a combination of auditory, visual, and vibrotactile feedback for wall collisions.

    Abstract 360 images and video have become extremely popular formats for immersive displays, due in large part to the technical ease of content production. The second experiment examined the effects of the electric current itself on the intensity of their perception of the softness, hardness and stickiness of a virtual object. Across three case studies, we demonstrate the efficacy of this approach, and how it supports a variety of metrics for comprehensively bench-marking distributed virtual environments. These techniques take advantage of the cursors current position or the users gaze direction for collocating the wiggle rotation center and potential targets. Analysis of proximity-based multimodal feedback for 3d selection in immersive virtual environments abstract interaction tasks in vr such as 3d selection of objects often suffer from reduced performance due to missing or different feedback provided by vr systems than during real-world interactions. The experimental results demonstrated that the participants had a feeling of presence and felt a steep stair gradient under the condition of haptic feedback and viewpoint manipulation based on the characteristics of actual stair walking data. We have conducted a user study that shows that our method brings significant performance improvement in vr and ar environments, on tasks that include tracking, matching, searching, and ambushing objects of interest. It takes time and practice to gain the coordination needed to become a competent driver and this can be even more of a challenge for someone with a disability. Overall, the translational technique performed better than the interpolated reach technique and was more robust for situations with larger mismatches between virtual and physical objects. We designed three visual transformations for behavioral phenomena of social interactions eye contact, joint attention, and grouping.

    Adding vibrations had significant impact on the perceived realism but not on the electro-dermal activity. This process also creates opportunistic global heading measurements to improve pose estimates. However with orientation drift, vr users implicitly lean their heads and bodies sidewards. The inserted medium warps the exitant lightfield in a way that increases the potential viewing angle. Instead, we propose a combination of auditory, visual, and vibrotactile feedback for wall collisions.

    Then, participants had to estimate if the remotely perceived translation was faster or slower than the actualphysically performed translation.
