The purpose of this research was to design, implement and evaluate the usability of a digital pilot system that adapts the Language and Communication subject section of the PSU (Chilean college entry exam), allowing for equal and autonomous participation by learners with visual disabilities in the college selection process. The study was carried out in two stages during the years 2010 and 2012. The pilot project was carried out in December of 2010 in three different regions of Chile, at the same time as the regular process for taking the PSU. Based on the initial results from 2010, the system was redesigned, implemented and evaluated in order to create the final version. The results for the final version of the tool designed demonstrate a high level of usability. This work provides a detailed analysis and discussion of the results obtained in 2012, as well as future directions regarding the issue at hand.
