During my graduation internship I made many concept proposals. 

After a customer conversation by the project manager and/or sales manager, a concept  for a VR or AR application was developed together with the concept and design team. One of the teammembers then created a concept deck with the following structure:
the briefing, context, inspiration, the idea with a  step-by-step elaboration, devices/ hardware, implementation process. 

These are some concept decks that I have made, ranging from concepts for VR training, VR and AR promotional applications, AR visualization apps and 360 degree videos.
