User Scenario Summary
1
Display of electronic teaching content in general forms, such as slides, text, and video display.
2
Support writing and freehand drawing.
3
Support situational and vivid explanation(e.g. display concrete and highly simulated teaching materials), guided imagination, and enhanced attention.
4

Content development
In order to evaluate the feasibility, usability, and acceptability of HoloBoard in subsequent user experiments, the following development goals are required when developing teaching content for HoloBoard
1
Choose one of appropriate Grade and curriculum content for HoloBoard.
2
Exploit and embed HoloBoard’s unique features as much as possible into the pedagogical process.
3
Design teaching goals that are easy to evaluate in the user study.
Based on the guideline given above, we have iterated our prototype via
30+
4+
2-5 h
2
designers, engineers, and participating teachers of HoloBoard development team intensively conducted online and in-person participatory design workshops
formal participatory design workshops
each intensive workshops
within two month, Jul 2020 - Aug 2020. Iteration and version upgrade happened every two workshops
