VotkA: 3D Visualization of the k-means Algorithm using Fiducials, Processing, TUIO and OSCRemote

I am going to present a few projects on my blog in which I collaborated in one or the other way. This post introduces Fabio Campos‘s VotkA (Visualization of the k-means Algorithm) project of the course Visualization in the Master’s studies of Computer Sciences at the RheinMain University of Applied Sciences. Fabio’s project is a 3D visualization of the k-means algorithm applied to Fisher’s dataset. The user can interact with the visualization via reacTIVision/Fiducials or the OSCRemote application on the iPhone/iPod Touch.

In VotkA users can interact with a three-dimensional cluster analysis visualization via a Tangible User Interface (TUI), the iPhone app OSCRemote or both in parallel. The TUI is provided by a small box that is technically based on Seth Sandler’s cheap multi-touch pad (you can see the box in the youtube video at the end of this article). On top of the box fiducials from reacTIVision are being tracked. Whenever a fiducial is being recognized a TUIO message with the fiducial’s id, position and rotation will be sent to VotkA.

Vispol Multi-Touch Video

This video demonstrates the fundamental multi-touch functions of Vispol. The demonstrated functions contain the creation and modification of persons and objects and connections. Additionally, examples for the application of the layout functions in Vispol are being introduced.

My Master’s Thesis Project: Vispol – An Interactive Scenario Visualization

As part of my Master’s thesis with the title Conception, Realization and Evaluation of Multi-Touch Interfaces for Interactive Visualizations, there has been the goal to create an interactive visualization that can be used via multi-touch. Finally, this visualization should be evaluated, which means it should be thoroughly tested and there should be some results in numbers.

Vispol on Sensory Mind‘s Round Table:

Paper: Read a summary about Vispol in this paper.

Background information:
This multi-touch visualization should be different from the common multi-touch use cases scaling/rotating images and zooming in maps. Additionally, this visualization should have a dedicated use and should not just be a prototype that demoes basic multi-touch capabilities.

I have been intrigued by the interactive visualizations in Minority Report, which provided natural user interaction for profiling activities of a policeman in future.

A few Multi-Touch Impressions from the Cebit ’09

At the Telekom booth there has been a long kind of bar multi-touch table. It is not rectangular but a curve. However, the quality of the projection has not been even as the creators of this table used different projections and did not get the projection illumination even. The application has been quite simple: Photo and video browsing. Anyway, it is looking very impressive:

Wivi: Wikipedia Visualization

Simon Lehmann, a fellow student of mine from the visualization classes of the Computer Sciences department at the Wiesbaden University of Applied Sciences, has created the very nice Wikipedia visualization Wivi in the work of his Diploma thesis:
