In this work, we propose to use an approximate 2D map of the environment generated from the latest environment modeling technology and enhance the object manipulation performance for the touch based mobile augmented reality. We validated the advantage of the proposed interface through a pilot experiment and confirmed that the use of the 2D map helps reduce the task completion time almost 2 times and improve the usability as well.

Human activities can have a lasting impact on the environment and society. Environmental impact assessment (EIA) which focusses on evaluating the impact of proposed developmental projects on the environment, helps in transparent decision-making and involves multiple stakeholders. However, EIA is data and effort-intensive and often becomes complex and long-drawn. Moreover, EIA is currently performed using primarily two-dimensional traditional mediums which could be vastly restrictive and difficult to navigate and comprehend. Here, we present an immersive approach which can create 3D interactive elements, modelling the real-world using augmented/mixed reality. Because of the inherent benefits of using three-dimensional representations and associated real-world interactions, we posit that our approach will facilitate better and faster, collaboration-enabled analysis of a developmental project proposal, thereon reducing processing time and promoting high fidelity.

With the adoption of mobile head mounted displays (HMDs) amongst non-experts outside of lab settings, it becomes increasingly important to understand what factors influence a holistic mobile virtual reality (MVR) user experience. We present the results of a field study (N=34), in which we used three methods - a drawing task, a storytelling exercise, and the technology acceptance questionnaire (TAM) - to explore factors, beyond technical capability, that influence the user experience of HMDs. Our analysis (1) highlights factors that designers and researchers can adopt to create and evaluate socially acceptable MVR systems for non-expert users outside a lab context, and (2) puts these factors in context with existing research from industry and academia.

We present the design and evaluation of Scalebridge VR, an immersive educational game that teaches children the mathematical skill of proportional reasoning. The game uses brain-computer-interface-based adaptive level difficulty to modulate difficulty of the game based on the player’s attention and meditation state. The game is an adaptation of previously introduced Scalebridge game that did not use virtual reality, but was shown to be an effective tool for learning proportional reasoning.

Text entry is still a challenging task in modern Virtual Reality (VR) systems. The lack of efficient text entry methods limits the applications that can be used productively in VR. Previous work has addressed this issue through virtual keyboards or showing the physical keyboard in VR. While physical keyboards afford faster text entry, they usually require a seated user and an instrumented environment. We introduce a new keyboard, worn on a hawker’s tray in front of the user, which affords a compact, simple, flexible, and efficient text entry solution for VR, without restricting physical movement. In our new video condition, we also show the keyboard only when the user is looking down at it. To evaluate our novel solution and to identify good keyboard visualizations, we ran a user study where we asked participants to enter both lowercase sentences as well as complex text while standing. The results show that text entry rates are affected negatively by simplistic keyboard visualization conditions and that our solution affords desktop text entry rates, even when standing.

Interactive user interfaces in head-mounted Augmented Reality environments are not always projected onto a physical surface. However, operating such free-floating interfaces by touch gestures is challenging because they do not provide haptic feedback. Considering a pointing gesture, in this work we present a user study evaluating the benefits of increasing the arm position sense for operating non-haptic interface. Our findings confirm that haptic feedback is required and show that an increased arm sense compensates for the lack of haptic feedback. The results suggest that applying 0.3 times of the pointing arm’s weight significantly speeds up direct object selection for free-floating interfaces. We also show that the correction phase of the underlying pointing movement is affected by boosting the arm sense.

The implementation of Virtual Reality (VR) tools in criminological research is very scarce, and almost non-existent in the fear of crime (FoC) field. Our objective is to assess the feasibility of Immersive Technologies for research on FoC. To do so, a simulation (360° video) grounded on the manipulation of environmental variables (street lighting) was conducted. Our preliminary results suggest that: (a) virtual simulation of absence of urban lighting elicits experiences of FoC, and (b) that simulation of experiences of FoC in virtual reality is an adequate strategy for analysis of this phenomenon.

People who cannot use their hands may use eye-gaze to interact with robots. Emerging virtual reality head-mounted displays (HMD) have built-in eye-tracking sensors. Previous studies suggest that users need substantial practice for gaze steering of wheeled robots with an HMD. In this paper, we propose to apply a VR-based simulator for training of gaze-controlled robot steering. The simulator and preliminary test results are presented.

Effects of latency in a visual feedback system during path-steering tasks were examined. Input movements were recorded in high speed and projected with controlled latency, while a user was required to drag an object through a tunnel path. We tested the system with 10 people and analyzed the duration based on the steering law and revealed that the latency of visual feedback beyond 64.3 ms was associated with reductions in user performance, which provides suggestions in developing user-oriented interface designs.
