VR and AR hold enormous promises as paradigm-shifting ubiquitous technologies. The investment in these technologies by leading IT companies, as well as the buy-in and general excitement from outside investors, technologists, and content producers has never been more palpable. There are good reasons to be excited about the field. The real question will be if the technologies can add sufficient value...
I have been working in VR and interactive 3D for a long time. I have had the pleasure of knowing and working with many of the people that are directly responsible for creating the magic in the world that we live in today. These are the people that started with a virtual blank page and created their own reality. Their vision defined a vector into their future that we have had the privilege of extending...
The emotional response a person has to a living space is predominantly affected by light, color and texture as space-making elements. In order to verify whether this phenomenon could be replicated in a simulated environment, we conducted a user study in a six-sided projected immersive display that utilized equivalent design attributes of brightness, color and texture in order to assess to which extent...
The increasing availability of intensely immersive virtual, augmented and mixed reality experiences using head-mounted displays (HMD) has prompted deliberations about the ethical implications of using such technology to resolve technical issues and explore the complex cognitive, behavioral and social dynamics of human ‘virtuality’. However, little is known about the impact such immersive experiences...
Traditionally in virtual reality systems, head tracking is used in head-mounted displays (HMDs) to allow users to control viewing using 360-degree head and body rotations. Our research explores interaction considerations that enable semi-natural methods of view control that will work for seated use of virtual reality with HMDs when physically turning all the way around is not ideal, such as when sitting...
For many virtual reality applications, a pre-calculated fly-through path is the de facto standard navigation method. Such a path is convenient for users and ensures coverage of critical areas throughout the scene. Traditional applications use constant camera speed, allow for fully user-controlled manual speed adjustment, or use automatic speed adjustment based on heuristics from the scene. We introduce...
Recent breakthroughs in consumer level virtual reality (VR) headsets are creating a growing user-base in demand for immersive, full 3D VR experiences. While monoscopic 360-videos are perhaps the most prevalent type of content for VR headsets, they lack 3D information and thus cannot be viewed with full 6 degree-of-freedom (DOF). We present an approach that addresses this limitation via a novel warping...
The proliferation of head-mounted displays (HMD) in the market means that cinematic virtual reality (CVR) is an increasingly popular format. We explore several metrics that may indicate advantages and disadvantages of CVR compared to traditional viewing formats such as TV. We explored the consumption of panoramic videos in three different display systems: a HMD, a SurroundVideo+ (SV+), and a standard...
In this paper we present an immersive virtual reality user study aimed at investigating how customers perceive and if they would purchase non-standard (i.e. misshaped) fruits and vegetables (FaVs) in supermarkets and hypermarkets. Indeed, food waste is a major issue for the retail sector and a recent trend is to reduce it by selling non-standard goods. An important question for retailers relates to...
This work presents an evaluation study in which the effects of a penalty-based and a constraint-based haptic rendering algorithm on the user performance and perception are analyzed. A total of N = 24 participants performed in a within-design study three variations of peg-in-hole tasks in a virtual environment after trials in an identically replicated real scenario as a reference. In addition to the...
We present the design and development of a fully immersive virtual reality (VR) system that can provide prop-based haptic feedback in an infinite virtual environment. It is conceived as a research tool for studying topics related to haptics in VR and based on off-the-shelf components. A robotic arm moves physical props, dynamically matching pose and location of an object in the virtual world. When...
Producing sensations of motion in driving simulators often requires using cumbersome and expensive motion platforms. In this article we present a novel and alternative approach for producing self-motion sensations in driving simulations by relying on haptic-feedback. The method consists in applying a force-feedback proportional to the acceleration of the virtual vehicle directly to the hands of the...
As the focus of virtual reality technology is shifting from singleperson experiences to multi-user interactions, it becomes increasingly important to accommodate multiple co-located users within a shared real-world space. For locomotion and navigation, the introduction of multiple users moving both virtually and physically creates additional challenges related to potential user-on-user collisions...
We developed “Finger Glove for Augmented Reality” (FinGAR), which combines electrical and mechanical stimulation to selectively stimulate skin sensory mechanoreceptors and provide tactile feedback of virtual objects. A DC motor provides high-frequency vibration and shear deformation to the whole finger, and an array of electrodes provide pressure and low-frequency vibration with high spatial resolution...
We investigate the effect of vibrotactile feedback delivered to one's feet in an immersive virtual environment (IVE). In our study, participants observed a virtual environment where a virtual human (VH) walked toward the participants and paced back and forth within their social space. We compared three conditions as follows: participants in the “Sound” condition heard the footsteps of the VH; participants...
