 USABILITY OF CONSUMER-ORIENTED PRODUCTS
What is it?
Typical examples of consumer-oriented products include consumer electronics, home/office products, telecommunication devices, software, website, etc., each of which has now become an important part of our everyday lives. As far as these products are concerned, usability means 'the ability of a product to satisfy the user in terms of the performance as well as the image/impression aspects (Kwahk, 1999)'. In this definition, the performance is similar to the traditional understanding of the usability concept (i.e, efficiency, effectiveness, etc.), whereas the image/impression indicates the emotional aspects of user satisfaction towards the product user interface.
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 framework of mobile phones (KOSEF, 2000. 9 ~ 2001. 9). (This project is being performed by the courtesy of the Korea Science and Engineering Foundation (KOSEF) -- I'm an awardee of KOSEF Postdoctoral Fellowship program, and Dr. Robert C. Williges in Virginia Tech is my advisor.)
  2. Usability evaluation for home/office devices, KRISS, 1998. 11 ~ 2002. 10
  3. Analysis of user satisfaction for mobile phones, LG Telecom, 2000. 4 ~ 2000. 10
  4. Development of usability evaluation technique, STEPI, 1996. 11 ~ 1998. 10
  5. Development of a usability evaluation method for the CFMS user interface of UCN 3,4, KAERI, 1996. 4 ~ 1996. 11
