Trinity Western University (TWU) students bring more human faces to online learning by building lightboards that allow professors to look directly into the camera while drawing and illustrating on lighted glass.

Through a matching grant from ECO Canada, Trinity Western hired two Computing Science students to build lightboards – a glass “chalkboard” that is fully lighted and transparent, useful for lecture recording and remote teaching.

Students Jacob Pettigrew (BSc Computing Science, 2021) and Dave Garcia (BSc Computing Science, 2024) began their work on July 20. They are committed to building two lightboards–and more–if they are able.

The human element of online learning

Pettigrew hopes to help other students succeed in their studies this fall. “I am excited about building the lightboards because I believe that the transition to online school in the fall will be difficult for many people, and the use of lightboards can make this transition easier,” he said.
