Unfortunately, whomever edited the video only shows the speaker and not the content of the slides, which makes it pretty hard to follow the speaker's points. For example, the speaker will mention examples of doors, but no doors are shown, only the speaker looking to the side (eg. seek to 34 minutes in the video). There's also no link to the slides or accompanying materials that would help understand the material that I can see. Unfortunate, since it looked pretty interesting.
