We present a novel immersive environment for the interactive analysis of nanoscale cellular reconstructions of rodent brain samples acquired through electron microscopy. The system is focused on medial axis representations (skeletons) of branched and tubular structures of brain cells, and it is specifically designed for: i) effective semi-automatic creation of skeletons from surface-based representations of cells and structures ii) fast proofreading, i.e., correcting and editing of semi-automatically constructed skeleton representations, and iii) useful exploration, i.e., measuring, comparing, and analyzing geometric features related to cellular structures based on medial axis representations. The application runs in a standard PC-tethered virtual reality (VR) setup with a head mounted display (HMD), controllers, and tracking sensors. The system is currently used by neuroscientists for performing morphology studies on sparse reconstructions of glial cells and neurons extracted from a sample of the somatosensory cortex of a juvenile rat.

Laryngoscopy or endotracheal intubation is a common medical procedure where a tube is passed into the lungs of patients for providing oxygen or other anesthetic gas. Improper intubation can be life threatening; hence, emphasis is laid on proper hand-eye coordination and an understanding of proper exertion of pressure on the patient’s body. This paper proposes a haptic-based implementation of endotracheal intubation to address shortcomings in existing approaches.

Selecting 3D regions-of-interest (ROI) in surface geometry is essential for 3D modeling, but few 3D user interfaces using fully manual input for ROI selection exist. Furthermore, their relative performance is not well studied. We present an evaluation comparing three ROI techniques: Volume Cube [Ulinski et al. 2007], Slice-n- Swipe [Bacim et al. 2014], and Yea Big Yea High Selection [Jackson et al. 2018]. Results show that Yea Big Yea High is best for tasks requiring high accuracy and speed, but modifications may be needed for use in dense geometry or with non-convex ROI.

Exploration of Augmented Reality technologies has increased substantially and the increase in both popularity and technological maturity has also led to several applications being developed for educational and museum environments. Specifically, a greater focus has been placed upon creating memorable experiences that both attract and educate museum patrons. Attempts to do this involve creating both Virtual Reality and Augmented Reality experiences, such as having users enter into immersive worlds that demonstrate the history of a certain time period, or applications that overlay life-like models of those animals in the very room the user is standing in. Many of these experiences are quite exceptional but begin to lack in variety when moving towards the art gallery, and mainly focus on making painting information more accessible. In an attempt to address this, this project outlines the design and evaluation of a proof-of-concept meant to study if adding interaction through Augmented Reality to paintings themselves would be both technologically feasible and desirable.

We investigated the performance of 3D pointing using direct touch in a planar surface condition (PC) and a spherical surface condition (SC). In addition, we examined the performance in terms of Fitts’ law. Although the results showed that the performance in SC was slightly worse than PC, SC was higher conformed to Fitts’ law than PC without the conditions involving head rotation (PC’s and SC’s R2 is 0.945 and 0.971, respectively).

We present an interactive virtual-reality (VR) fire extinguisher that provides both realistic viewing using a head-mounted display (HMD) and kinesthetic experiences using a pneumatic muscle and vibrotactile transducer. The VR fire extinguisher is designed to train people to use a fire extinguisher skillfully in real fire situations. We seamlessly integrate three technologies: VR, object motion tracking, and haptic feedback. A fire scene is immersed in the HMD, and a motion tracker is used to replicate a real designed object into the virtual environment to realize augmented reality. In addition, when the handle of the fire extinguisher is squeezed to release the extinguishing agent, the haptic device generates both vibrotactile and air flow tactile feedback signals, providing the same experience as that obtained while using a real fire extinguisher.

This article investigates the impact of waiting in Virtual Reality (VR) on the perception of time. We manipulated the visual quality of a virtual room replicating a real one (360-picture vs. 3D-model) with and without avatar embodiment (no-avatar vs. avatar). We only observed a significant difference in the estimated time duration between the real and the virtual worlds when using no avatar within a 3D model of the room. Our early results suggest that a VR environment with an avatar and a simple 3D model or 360 picture room is not significantly perturbing time perception and thus could be used for diagnosis and therapy of psychiatric conditions related to altered time perception.

Technologies for Virtual, Mixed, and Augmented Reality (VR, MR, and AR) allow to artificially augment social interactions and thus to go beyond what is possible in real life. Motivations for the use of social augmentations are manifold, for example, to synthesize behavior when sensory input is missing, to provide additional affordances in shared environments, or to support inclusion and training of individuals with social communication disorders. We review and categorize augmentation approaches and propose a software architecture based on four data layers. Three components further handle the status analysis, the modification, and the blending of behaviors. We present a prototype (injectX) that supports behavior tracking (body motion, eye gaze, and facial expressions from the lower face), status analysis, decision-making, augmentation, and behavior blending in immersive interactions. Along with a critical reflection, we consider further technical and ethical aspects.

Augmented reality(AR) provides a unique viewing experience at museums where people understand abstract history through physical artifacts. Although AR usage in museum settings has been increasing, it is not well understood how AR viewing experience differs in different groups of visitors, which can be problematic considering that museums are places visited by diverse groups of people. In this study, we evaluate the differences in AR experiences according to the characteristics of the visitors. The results show the effect of AR usage in museum settings with visitors’ different age groups and motivations for visiting.
