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… (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)
View-dependent rendering techniques are an important tool in Spatial Augmented Reality. These allow the addition of more detail and the depiction of purely virtual geometry inside the shape of physical props. This paper investigates the impact of different depth cues onto the depth perception of users.
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)

—Physical simulations provide a rich source of time-variant three-dimensional data. Unfortunately, the data generated from these types of simulation are often large in size and are thereby only experienced through pre-rendered movies from a fixed viewpoint. Rendering of large point cloud data sets is well understood, however the data requirements for… (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)
