The challenges, and meaning, of innovation

Three students in an upper-level physics class designed and built a tabletop lightboard for their final project this semester.

Lightboards are used in creating online videos for classes. They allow instructors to write on a glass pane as they would a whiteboard. A camera is positioned facing the instructor, capturing the writing on the glass as the instructor speaks. The image must then be flipped so that the writing can be read in the video. The approach is especially popular among STEM instructors.
