Abstract

Blind and visually impaired people are among those who require very specific types of assistive technology. This type of technology has been a research and development focus for decades. As technology has matured, more affordable and practical solutions have entered the market. Unfortunately, this has not resulted in a very positive trend in terms of acceptance or adoption. Our research on usability and user experience indicated that there is a need to extend standardized questionnaires when evaluating assistive technology. This paper details the development of an evaluation model with extended contexts that can be used with cooperative assistive technology aimed for blind or visually impaired people and their caretakers. We present our evaluation setting and procedure for the model. The development of the model is based on testing, literature review, expert interviews, and discussions. The extended contexts should also contribute towards the trend of modularity with standardized user experience questionnaires.
