AbstractCoronary heart disease (CHD) is the number one killer in the United States. Although it is well known that CHD mainly occurs due to blocked arteries, there are contradictory results from studies designed to identify basic causes for this common disease is. To find out more about the true reason for CHD, virtual models can be employed to better understand the way the heart functions. With such a model, scientists and surgeons are able to analyze the effects of different treatment options, and ultimately find more suited ways to prevent coronary heart diseases. To investigate a given model, appropriate navigation methods are required, including suitable input devices. For the visualization, graphics cards originally designed for gaming applications are used; so, it is a just natural transition to adapt gaming input devices to a visualization system for controlling of the navigation. These devices are usually well designed with respect to ergonomics and durability, yielding more degrees of freedom in steering than two-dimensional input devices, such as desktop mice. This poster describes a visualization system that provides the user with advanced control devices for navigation enabling interactive exploration of the model. Force-feedback and sound effects provide additional cues. Force-Feedback-Enhanced NavigationVirtual biomedical models can help to better understand how diseases affect the function of organs and parts of the human body. By thoroughly exploring such a model, scientists and surgeons are able to analyze the effects of different treatment options, and ultimately find more appropriate ways to prevent diseases. Specifically a virtual model of the vascular system of the heart can aid in finding out more about the way the heart functions, and might give insights in what causes conditions such as coronary heart disease (CHD). Exploring such a model and visually inspecting certain regions of interest is usually limited by restrictions of traditional input devices, such as keyboard and mouse, often resulting in a non-intuitive and * e-mail: wischgoll@siggraph. compares different 6DOF input devices, some of which are derived from 2D devices, such as a mouse, and analyzes their performance when used by different test persons. He showed that there is no optimal input device so far that fits all the needs of the user while using the different systems. In a similar tube-shaped environment than the one presented in this poster, Wan et al. [4] derive an optimal path for an automatic flight through a colon based on a distance field approach to avoid collision with the colon walls.In this work, a visualization system for cardiovascular trees has been developed, which enables the exploration of a detailed geometric 3D model of the cardiovascular tree within a scalable vir...

Review of Serious Games for Medical Operation

“…Choi et al [68] used a miniature vibrating motor to provide P300 with vibrating tactile force to improve BCI performance. Wischgoll et al [69] added a haptic device to the game to study coronary heart disease to enhance interaction. The input device uses SideWinder force-feedback wheel, and the force feedback signal is used to represent the collision.…”

“…They planned to add the conversation sound of the medical staff diagnosis in the follow-up research as a kind of information output to indicate whether the performance is good. Wischgoll et al [69] added not only haptic interaction but also sound feedback to the surgical training of coronary heart disease. Sound effects using the DirectSound software accompany the signal to provide additional cues to enhance the game experience and improve the training effect.…”
