We found an interesting Article about “A blind Persons Interactions with Technology” in the ACM (Association for Computing Machinery) by Kristen Shinohara and Josh Teneberg from the University of Washington.
The study is an in-deapth exploratory and descriptive case study about a blind person using various technology at home in everyday actions, such as the screen reader JAWS, a BrailleNote, Braille tape for labelling CDs or reading the time on a Braille watch, etc.
Other than in studying interactions in laboratories here you can get an insight on how and why or why not technologies are actually used in everyday life, leaving the artefacts in the context of use.
