Graph Navigation with Eye-tracker

Creating a gaze-aided graph navigating application using Unity3D and Pupil-lab.

Features:

• Dataset from wikipedia is sampled and projected in 3D space using Force-directed-layouts.
  • Inspired by this post.
• Supports keyboard/mouse controls.
• Navigation/Rotation and Dramatic Camera in Node selection.
• Information panel added for each selected Node to render extra information.
• Bubble technique to narrow down selection area for user[1].

Why?

• Part of the masters project supervised by the Human-Computer-Interaction Group, Hamburg University.

TODO:

• Implementation of Dwell Time.
• Integrate HapRing[2] as a control device.
• Enhance the eye tracking with regression/interpolation[3].
