My friend Stuart Rankin, from Six Cat Studios, asked me the following questions about GeoPose. Not sure of the answers, I turned to the OARC, the Open Augmented Reality Cloud. I soon received the following reply from Christine Perey, one of the forces behind the OARC. Thanks to both Stuart and Christine!
How will GeoPose deal with two objects on the other side of the world?
- each and every real person, place and thing can have a GeoPose at any moment in time. For digital objects or models, a GeoPose can be specified for one point (an anchor)
- two or more objects can calculate properties between themselves (e.g., distance, orientation) based on their GeoPose.
If this information does not match the question you had in mind, let me know. The point to keep in mind is that GeoPose are unique, so the locations and number of objects in your question would determine the number of GeoPose.
Does the theory of relativity have an effect (like it has with GPS)?
- Great question. It seem so, and this point will be further analyzed.
Does it account for things that are supposed to be still, changing. like with an earthquake for example or shifting continents ?
- we have not yet decided if there will be one universal coordinate reference system (unlikely) and how we will deal with ones that are not well defined or per.
- you might want to study this wikipedia page https://en.wikipedia.org/wiki/ECEF
Who decides where point 0,0,0 is (above)?
What happens when companies or countries reject the standard because they want to use their own which they think is better or provide political benefit or commercial?
- there will not be interoperability and the services will be confined to “walled gardens” just like mobile phones were in the earlier generations.
