System Software Lab (SS lab) at University of Seoul is conducting researches on the system software for embedded computing systems. Main research areas include real-time systems, industrial informatics, and multimedia. Industrial practitioners and students who are interested in our studies are always welcomed. Please contact Prof. Sung for further information.  

Mechanical informatics

Recently, mechanical systems are rapidly integrating with information technologies. SSlab studies IT-mechanical systems with a focus on following area:

  • Open software platform for industrial automation.
  • System software for real-time systems.


Emotional messaging

This project deals with the development of an emotional messenger for automated recognition and expression of emotions for smart phones and IPTVs.

  • Automated emotion recognition from chat texts
  • Facial expression tracking and animcation (using Visage technologies)
