Professor Ron Dotson reviews OSHA regulations for scaffolding in this AR video. This video serves as a preview session for an assignment in OSH 379: Construction Safety. This AR video is different from the previous AR projects we created. We used a virtual 3D scaffolding model and a mini scaffolding model in this project. The virtual 3D model was created by LX scaffold and available to download at Google 3D warehouse. We used Blender to edit the model to fit the needs of this lecture. This is the first time that we incorporated both virtual and real models in producing instructional videos for our courses. We would love to know if this approach works for you!
