Dr Rachel Blagojevic PhD

Senior Lecturer

Doctoral Supervisor
School of Mathematical and Computational Sciences

My research interests are in human computer interaction. In particular I am interested in the use of gesture-based interaction. One area of work is developing recognizers for sketched diagrams using digital pen input devices. Another area is exploring multi-modal interfaces using tangible and touch input.
