Mixed Reality (MR) is of increasing interest within technology- driven modern medicine but is not yet used in everyday practice. This situation is changing rapidly, however, and this paper explores the emergence of MR technology and the importance of its utility within medical applications. A classification of medical MR has been obtained by applying an unbiased text mining method to a database of...
Medical training systems often require the use of haptic interaction with deformable models and high visual fidelity. It is necessary to get a compromise between the geometric model and the deformation model in order to achieve the required frame rate for haptic interaction of 1000Hz. Frequently low level geometric models are used to describe the geometry of the object. This produces large data structures...
This paper presents recent additions to our Wheelchair-VR application, in particular the use of different drive configurations. We have previously shown that Wheelchair-VR can be used to improve driving skills. Here we consider the utility of the application in allowing users who are in the process of purchasing or upgrading a wheelchair to experience different configurations and options in a cost-effective...
Planning treatment of acute cardiac events that limit the blood supply to major organs is particularly difficult for interventional cardiologists. The treatment of pathologies, such as vascular stenosis, can have numerous unforeseen consequences as the blood resumes its flow. Their decisions are largely based on 2D medical imagery and their own experience. This work in progress presents a virtual...
We have developed an augmented reality tool for radiotherapy to view the real world scene, i.e. the patient on a treatment couch, combined with computer graphics content, such as planning image data and any defined outlines of organ structures. We have deployed our software to a number of consumer electronics devices (iPad, Android tablets, MS HoloLens). We suggest that, in contrast to other augmented...
We have designed Li Tu (Laı'Tu - Light Tube) as a customisable and low-cost (ca 30 Euros) human-computer interface. It is composed of an acrylic tube, a ball-bearing mirror, six LEDs and a webcam. Touching the tube causes frustrated internal reflection of light due to a change in the critical angle at the acrylic-skin boundary. Scattered light within the tube is reflected off the mirror...
We are developing a novel device for measuring hand power grip using frustrated total internal reflection of light in acrylic. Our method uses a force sensitive resistor to calibrate the force of a power grip as a function of the area and light intensity. This research is work in progress but results so far augur well for its applicability in medical and other application areas. The grip measurement...
Work in progress for the development of a novel virtual training environment for training a kidney biopsy procedure is presented. Our goal is to provide an affordable high fidelity simulation through the integration of some of the latest off-the-shelf technology components. The range of forces that are encountered during this procedure have been recorded using a custom designed force sensitive glove...
We have designed and developed a virtual environment to train rugby ball passing skills. Seeking to validate the system's ability to correctly aid training, an initial experiment was performed to examine the effect of stereoscopic technology and the physical screen's setup on the user's ability to perceive virtual distances correctly. Four participants with at least 10 years' experience of playing...
