Research and Projects

My main area of interest is User Interfaces with focus on usability and human computer interaction (HCI).

I'm also interested in the fields of Internet/Web programming, Network/Distributed computing, Information Retrieval, and Artificial Intelligence (AI).

Here's a list of projects at the U of M.

  1. Currently working on the Masters project to facilitate the concept of an attention manager to balance information awareness of a computer user with intelligent intrusion.
  2. Currently working on a project to improve the relevance of web search results, for the HCI class.
  3. Designed and developed an interface to a command based VLSI design and simulation program using Tcl/Tk as a group project for the User Interface Design class.
  4. Implemented a client-server model for the Computer Networks class.
  5. Implemented a motion detection algorithm (SSD method) and carried out some experiments for the Computer Vision class.
  6. Completed four different interface assignments with four different tools (CGI, Tcl/Tk, Visual Basic, and Java) for the GUI Toolkits class.
  7. Implemented collective communication operations in MPI (Reduce and All_Reduce) using MPI’s point-to-point communication operations for the Parallel Computing class. Also developed an MPI program to perform Gaussian elimination for the same class.
  8. Implemented parts of operating system features for the MIPS simulator for the Operating Systems class.
  9. Implemented a game called ‘Good Bet’ using CLIPS for the Expert Systems class.
  10. Carried out a Neural Networks project on sonar data as a group project for the Artificial Intelligence II class.
  11. Implemented A* algorithm to find shortest driving distances in the city of Minneapolis, for the Artificial Intelligence I class.
  12. Did a survey on automation of aeroplane cockpits for the Cognitive Science class.
  13. Did three group projects, one analyzing ergonomic issues of computer keyboards, one giving a research proposal to overcome ergonomic issues of the keyboard, and the other doing a job analysis for the jobs of printing and packing for the Human Factors and Ergonomics class.
