DCSR: A Digital Circuit Sketch Recognition System for Education Chapter uri icon


  • Digital logic is an important part of any engineering curriculum in todays digital era, and it is often taught visually through circuit diagrams. However, for students just learning logic, this process can be non-interactive, with students typically drawing and solving diagrams that will only be evaluated by a human grader later. This paper presents DCSR (Digital Circuit Sketch Recognition), a system that recognizes hand-drawn digital logic circuits through a web interface and calculates the truth value of its output based on students input. It allows users to draw freely and gives immediate feedback; DCSR aims to provide an interactive, sketch-based approach for educators to assist students in learning digital logic. Itwas evaluated by 15 electrical engineering students.
