360 Hotspots in Real Life

As part of a brief, I want to use the Oculus Quest at particular points for a walking tour. Essentially when a tour group gets to specific defined areas I would like to start the experience and end without the people wearing the headsets to have to do anything. What would be the easiest way to achieve this? Ideally, we would be walking with an IPAD that could act as a control.

Thank you
