I’d like to share a portion of a project we did five years ago for Microsoft, called the Lobby of the Future. This segment features a video tour across part of the company campus with time based hotspots that appear in context of the surroundings (I shot the video with a GoPro during Super Bowl Sunday, thus the low traffic).
There are a few techniques to make hotspots appear at specific times. One way is to hardcode a series of Reaches Time triggers as part of the video player. I chose instead to use Excel to list times, hotspot positions, descriptions, etc. and setup a timer that every second checks what hotspots should be made visible and not.
Here is the XP if you’d like to give it a try:
