Technical Communication
My interests: HCI, human performance, usability evaluation, social interaction between human and technologies, and technology for learning.
Current Project
- Eye-tracking based usability evaluation
- Information and communication technology for development
Previous Projects
- Performance Analysis of Pen-based Mode Switching
Five pen-based techniques for switching between ink and gesture modes were studied. A quantitative experimental study and a human performance analysis were conducted to evaluate the efficiency of these techniques.
- ZoomSelector
ZoomSelector is designed to reduce the cognitive effort for selecting small targets on a small screen while using a pen. It allows a user to perform approximate selection using a pie-menu like layout, which improves the interaction accuracy without increasing cognitive burden.
