-== Web-based knowledge visualizations (BA/HiWi) == 
- 
-{{ :research:knowledge-visualization.png?200}} 
- 
-The knowledge base visualization allows to display semantic environment maps, 
-objects, human poses, trajectories and similar information stored in the 
-robot's knowledge base. Its [[http://www.ros.org/wiki/mod_vis|current version]] 
-is written in Java and has grown old over the years. Recently, there has been 
-much progress in creating [[http://www.ros.org/wiki/interactive_markers|interactive 
-3D visualizations]] for ROS that can also be accessed with a 
-[[http://www.ros.org/wiki/wviz|web browser]]. This project is about creating 
-a web-based version of the visualization using these techniques. 
- 
-Requirements: 
-  * Good programming skills 
-  * Experience with JavaScript development 
-  * Knowledge of Web technologies (HTML, XML, OWL)

- 
-== Tools for knowledge acquisition from the Web (BA/MA/HiWi) == 
- 
-There are several options for doing a project related to the acquisition of 
-knowledge from Web sources like online shops, repositories of object models, 
-recipe databases, etc. 
- 
-Requirements: 
-  * Programing skills (Java) 
-  * Experience with Web languages and datamining techniques is helpful 
-  * Depending on the focus of the project, experience with database technology, natural-language processing or computer vision may be helpful

 + 
 +Integrating the eye tracker in the [[http://gazebosim.org/|Gazebo]] based Kitchen Activity Games framework and logging the gaze of the user during the gameplay. From the information typical activities should be inferred.

 +== Hand Skeleton Tracking Using Two Leap Motion Devices (BA/MA)== 
 + {{ :research:leap_motion.jpg?200|}}  
 + 
 +Improving the skeletal tracking offered by the [[https://developer.leapmotion.com/|Leap Motion SDK]], by using two devices (one tracking vertically the other horizontally) and switching between them to the one that has the best current view of the hand. 
 + 
 +The tracked hand can then be used as input for the Kitchen Activity Games framework.

 +== Fluid Simulation in Gazebo (BA/MA)== 
 + {{ :research:fluid.png?200|}}  
 + 
 +[[http://gazebosim.org/|Gazebo]] currently only supports rigid body physics engines (ODE, Bullet etc.), however in some cases fluids are preferred in order to simulate as realistically as possible the given environment. 
 + 
 +Currently there is an [[http://gazebosim.org/tutorials?tut=fluids&cat=physics|experimental version]] of fluids  in Gazebo, using the [[http://onezero.ca/fluidix/|Fluidix]] library to run the fluids computation on the GPU. 
 + 
 +The computational method for the fluid simulation is SPH (Smoothed-particle Dynamics), however newer and better methods based on SPH are currently present 
 +and should be implemented (PCISPH/IISPH).
  
-Competent object interaction requires knowledge about the structure and +The interaction between the fluid and the rigid objects is a naive one, the forces and torques are applied only from the particle collisions (not taking into account pressure and other forces).
-composition of objects. In an ongoing research project, we are investigating +
-how part-based object models can automatically be extracted from CAD models +
-found on the Web, e.g. on the [[http://sketchup.google.com/3dwarehouse|3D warehouse]].+
  
-We are looking for a student research assistant to push this topic forward. +Another topic would be the visualization of the fluid, currently is done by rendering every particle. For the rendering engine [[http://www.ogre3d.org/|OGRE]] is used.
-In close collaboration with the researchers of the Institute for Artificial +
-Intelligence, the student will work on extending the software for mesh +
-segmentation, implement novel algorithms, improve the integration of the +
-methods into the robot's knowledge base, and update the modules for visualizing +
-the segmentation results. Depending on the results, cooperation on joint  +
-publications may be possible.+
  
-This HiWi position can serve as a starting point for future Bachelor's, +Here is a [[https://vimeo.com/104629835|video]] example of the current state of the fluid in Gazebo. 
-Master's or Diploma Theses. Alternatively, we could extract a research +
-project that could be worked on as a Master's or Diploma Thesis.+
