Problems ! Recruitment of Par-cipants
-‐ Could not adver-se through usual sighted channels i.e. fliers, broadcast emails etc.
-‐ A different strategy had to be used
-‐ Referrals, School clubs, and Social media
! Screen Readers -‐ Different screen readers read at different rates. Causes cuts during narra-on
-‐ Screen readers could not read some sub-tles
-‐ Cap-oning changed to a more concise language
-‐ Computer Literacy
