Previous studies have examined the use of virtual environments (VEs) for stroke and similar rehabilitation. To be of real benefit it is essential that skills (re-)learned within a VE transfer to corresponding real-world situations. Many tasks have been developed in VEs, but few have shown effective transfer of training. We believe that, by softening the real/virtual divide, mixed reality techno...

Navigating between different virtual worlds, interface scales or task contexts has emerged as an interesting research area for Augmented and Virtual Reality interfaces. We have developed a transitional interface which allows users to smoothly move between exocentric Augmented Reality and egocentric Virtual Reality views. In this paper we report on the first user study to investigate performance...

We present a parameterized description of a subspace of the space of designs for immersive virtual reality comparison visualizations, as well as results of a user evaluation of the utility of these different parameters. Our work makes three contributions: a specific definition of comparison visualizations and their place in the scientific data cycle, advice derived from the user study for the d...

In this paper, we evaluate the usability of multimodal feedback for enhancing immersion in augmented reality (AR) based product design environments, introduced in the paper [1]. We study what effects occur when providing multi-sensory feedback to users. First of all, we compare design environments between conventional desktop based design environments and AR based design environments which supp...

The use of Virtual Reality (VR) technology to support the treatment of patients with phobia, such as the fear of flying, is getting considerable research attention. Research mainly focuses on the patient experience and the effect of the treatment. In this paper, however, the focus is on the interaction therapists have with the system. Two studies are presented in which the therapist user interf...

Sound gardens rely on location tracking technology to situate audio landmarks in public spaces, typically urban parks. These landmarks are surrounded by a proximity zone, and content relating to them is displayed to users within this region. In densely populated sound gardens, overlap between zones is inevitable and will result in simultaneous playback of multiple audio sources – a potentially ...

Testing ecological models for management is an increasingly important part of the maturation of ecology as an applied science. Consequently, we need to work at applying fair tests of models with adequate data. We demonstrate that a recent test of a discrete time, stochastic model was biased towards falsifying the predictions. If the model was a perfect description of reality, the test falsified...

The present study assessed the degree to which probabilistic reasoning performance and thinking style influenced perception of risk and self-reported levels of terrorism-related behavior change. A sample of 263 respondents, recruited via convenience sampling, completed a series of measures comprising probabilistic reasoning tasks (perception of randomness, base rate, probability, and conjunctio...
