Design of the architecture for text recognition and reading in an online assessment applied to visually impaired students

摘要

This paper describes the architecture for text recognition and reading in an online assessment applied to visually impaired students. For this purpose, it is intended to implement an online evaluation system exclusively to recognize alphanumeric information, i.e., letters and numbers, through the use of an Application Programming Interface or also known as speech and text processing API’s, where the computer can understand and respond in natural language. Usability tests were carried out based on ISO 9126-4, taking as variables to measure the effectiveness, efficiency, and satisfaction of the latter through a system usability scale or more commonly known as SUS (System Usability Scale).
