ART is an immersive analysis tool for the visual analysis of mobile health data. It visualises multidimensional data in augmented reality using an interactive 3D visualisation. The visualisation links related data points between several 2D scatter plots to create a 3D parallel coordinates visualisation. To benefit from well-established interaction techniques, the visualisation is anchored to a touch-sensitive tabletop.
This system is part of my Bachelor Thesis in Computer Science (B.Sc.) at the University of Konstanz, Germany.
The system is split into four separate applications:
- A web application (TypeScript + Angular) for controlling the visualisation
- A Unity3D (C#) application for creating a visualisation in augmented reality
- A web server (TypeScript + Node.js) for communication between the web application and Unity3D
- A library (C++11) for handling and processing camera images
In addition, there are several helper tools, e.g. for calibrating cameras, debugging, and OptiTrack tracking.
