Touching Data: Enhancing Visual Exploration of Flow Data with Haptics

IEEE Computing in Science & Engineering, Volume 20, Number 3, page 89-100 - May/June 2018
This work shows how it is possible to combine visual and haptic exploration of the dynamics of the cardiac flow in a patient specific human heart can. In the first image the left ventricle of the heart and one selected flow pathline is shown. Using a haptic interface, here shown as a gray arrow, force feedback can be used to trace the pathline. While moving along the pathline the anatomical context is instantly updated to reflect the progression of time. The small blue sphere shows the current position of the haptic proxy used to determine the force feedback, visualized with a red arrow. The right image shows the visuo-haptic system in use. This workstation is designed to align the physical haptic device with the corresponding visual representation in the virtual environment. This co-locates the visual and haptic representations.
