For this reflection, please read the following:

In Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '17). ACM, New York, NY, USA, 280-289.

In your reflection, address the following topics in 400-600 words (total, word count not including the questions you write for class):
1. Both of these projects help people who are blind, but use different methodologies in their user studies. One included both blind and sighted participants as a part of their user study population, while the other only included blind participants.
- When would you want to (or not want to) include sighted participants? Are there trade offs between the two approaches?
- What insights did Bigham et al. learn when comparing the results between visually impaired and sighted users that would not have been uncovered had they only worked with visually impaired users?
2. What about the second paper surprised you with respect to accomplishing tasks online? Any hardships that blind people experience that you did not expect?
Please remember to write 3-5 discussion questions for class.
