Visualization of Nature-VR head tracking

A visualization of head-tracking data taken while a patient viewed a panoramic image of a lake surrounded by trees. White circles show locations on the image which the patient was facing at different times. The same location data is aggregated into a heatmap in shades of blue to red behind the white circles.

Description

IU Research Technologies staff collaborated with IU School of Nursing and School of Medicine faculty to develop Nature-VR, a virtual reality-based cognitive intervention based on the restorative effects of nature. Guided by Attention Restoration Theory, researchers use Nature-VR to explore the associations between attention and several heart failure biomarkers as well as the effect of Nature-VR on cognitive performance, cardiac and neurological events, and mortality.

The Nature-VR headset records head orientation data, which are then visualized as heatmaps overlayed on the images shown to the patients. The workflow was first created in ParaView, then converted to a reusable script which can generate visualizations for many patients with a single command.
