Open Source Projects

A number of (open source) projects I created and I am responsible for. For support, please see the mailing lists on the project pages!

• jCores
  • jQuery for Java ;-)
  • provides many short-cuts to otherwise cumbersome Java operations
  • transparently makes use of all your CPUs

• Text 2.0
  • what if your book really knew where you are gazing at?
  • various videos and prototypes outlining what text & gaze can do

• Processing Easy Eyetracker Plugin (PEEP)
  • made for media and digital artists
  • use eye tracking in Processing to create stunning gaze-responsive demos

• Text 2.0 Framework
  • use eye tracking in your web browser
  • supports handlers like onGazeOver, onFixation, ...
  • enables you to record interaction sessions for later analysis

• Java Simple Plugin Framework
  • open-sourced core of our Text 2.0 framework.

• Context Sensitive Dashboard (230mb video!)
  • finds and manages links, files, folder and persons and notes related to the current context and anticipates future resources by monitoring current resources, provdes a visual backtrack upon the continuation of interrupted tasks
  • available upon request
  • (the video above is from an early version, the final one has some different widgets, see the thesis above. Especially the context switching part is not done on the console anymore, but by a dedicated context provider)
