 DEVELOPMENT/APPLICATION OF EMPIRICAL MODELS
What is it?
Suppose you've just designed a new product, software, hardware, consumer electronics, or whatever. You may then want to figure out how good or bad this product is to be appreicated by the users even before you release the product in the market. A possible solution is to use empirical models to predict the functional relationship between the degree of goodness/badness and the design features of the product.
What I've done and learned so far?
Here follows a list of research projects that I've been leading or involved in so far regarding this topic:
  1. Usability evaluation for home/office devices, KRISS, 1998. 11 ~ 2002. 10
  2. Analysis of user satisfaction for mobile phones, LG Telecom, 2000. 4 ~ 2000. 10
  3. Development of a framework for evaluating perceived image quality of a monitor, LG Electronics Co., 1998. 8 ~ 1999. 1
  4. Development of usability evaluation technique, STEPI, 1996. 11 ~ 1998. 10
  5. Building a human performance model using neural network, POSTECH, 1995. 1 ~ 1995. 12
