Abstract

Children with ASD may show permanent communication problems due to a decline in the effectiveness of persistence of the information transacted. L-PECS is an application for Android smartphones that uses an alternative language called PECS, based on image exchange. L-PECS allows to improve the persistence of information in work contexts, generating effective communicational instances, task follow-up, and supporting the labor insertion of people with ASD. This work performed user interface tests, user action tests, usability, and accessibility tests on 20 users operating L-PECS to define and show possible behaviors. L-PECS can encourage the hiring of people with ASD. (C) 2021 The Authors. Published by Elsevier B.V.
