Devi: evaluador computacional universal dirigido a personas con discapacidad visual en Ecuador

Devi is a tool that allows the collection of the evaluation that the blind person perceives of a received service. The device allows to obtain, in an objective way, the perception that the user has regarding the service subject to evaluation. The evaluator has flexibility to edit the questions within the program, modifying them to evaluate different key characteristics of the service. For greater versatility of the device, and taking into account the text recognition methods available for blind users, it was decided to provide ways of identifying data buttons with Braille text together with emoticons, basing the design of the buttons on SAM (self-assessment manikin). The program’s response to the press of a button is text converted to speech, allowing the device to add extra support to the user, whether the user is familiar with Braille text or not.
