Digital Systems Laboratory for Visually Impaired Students

This paper describes how the practical sessions of the Digital Systems Laboratory within the Computer Science Degree have been adapted to allow a visually impaired student to take part in the practical sessions. Regular students use a computer--aided design tool (OrCAD) for digital design in their practical assignments. This work shows how the use of special instrumentation allows visually impaired students to work with regular students in the same lab, where the CAD tool is installed. The teaching methodology and the obtained assessments are introduced here. Some specific practical materials have been designed and they are described in this work; the design of a special buzzer is also presented.
