So you source 10 different YouTube videos that show tips on playing ‘Pool’, ‘Snooker’, ‘Tennis’ etc. You make a note of specific starting points and how long the actual ‘Tip’ plays for.
You then upload that as a command in this system and assign whatever phrase you like to it. e.g.
“Improve my stance”
Might launch a video onto a large screen next to the pool table and play a subsection automatically. It would then stop at the end of the ‘Tip’ ready for a new command. As a business venture you can publish your entire command set for download at x price.
