Hi. I come from a design background, and the field of Interaction Design
in India (small though it is) is full of product and visual design
professionals who crossed over some time during the past 15 years and
are largely self-taught.
Personally, I taught my first course on user interface design back in
1994, and have been a teaching Interaction Design professionally since
1998 in a design school.
When I teach a course on HCI / Interaction Design / Usability, I sorely
miss teachers / courses from the backgrounds of cognitive psychology,
instructional design and written communication.
