Pain is a protective perceptual response shaped by contextual, psychological, and sensory inputs that suggest danger to the body. Sensory cues suggesting that a body part is moving toward a painful position may credibly signal the threat and thereby modulate pain. In this experiment, we used virtual reality to investigate whether manipulating visual(More)
Effective designs rarely emerge from good structural design or aesthetics alone. It is more often the result of the end product's overall design integrity. Added to this, design is inherently an interdisciplinary collaborative activity. With this in mind, today's tools are not powerful enough to design complex physical environments, such as command control(More)
Spatial Augmented Reality allows the appearance of physical objects to be transformed using projected light. Computer controlled light projection systems have become readily available and cost effective for both commercial and personal use. This chapter explores how large Spatial Augmented Reality systems can be applied to enhanced design mock-ups. Unlike(More)
Barite chimneys are known to form in hydrothermal systems where barium-enriched fluids generated by leaching of the oceanic basement are discharged and react with seawater sulfate. They also form at cold seeps along continental margins, where marine (or pelagic) barite in the sediments is remobilized because of subseafloor microbial sulfate reduction. We(More)
This poster presents the concept of combining two display technologies to enhance graphics effects in spatial augmented reality (SAR) environments. This is achieved by using an ePaper surface as an adaptive substrate instead of a white painted surface allowing the development of novel image techniques to improve image quality and object appearance in(More)
BACKGROUND Proprioceptive imprecision is believed to contribute to persistent pain. Detecting imprecision in order to study or treat it remains challenging given the limitations of current tests. OBJECTIVES The aim of this study was to determine whether proprioceptive imprecision could be detected in people with neck pain by testing their ability to(More)

In this paper we present a new method for accelerating ray tracing of scenes containing NURBS (Non Uniform Rational B-Spline) surfaces by exploiting the GPU's fast z-buffer rasterization for regular triangle meshes. In combination with a lightweight, memory efficient data organization this allows for fast calculation of primary ray intersections using a(More)
