I’m out of town the next couple weeks and can’t play, but what Jason and I did is this:
Mounted an iPad in landscape orientation about 7 ft off the floor perpendicular to the table such that the view is the full table, from the side. Head on the left, foot on the right in the view. By agreement we will be using diamonds on the long rail as 1-8 left to right and diamonds in the short rail 1-4 far to near in the view. Coordinates always long first, short second, so balls are starting at break positions: red= 6.0/2.0 position; yellow at 2.0/2.0; white at 2.0/2.3.
We connected using FaceTime and could see each other’s table and talk to each other. He broke, made a point or two, then missed. He would tell me where the balls were after his shot using our coordinate system and I would locate my balls to those positions and take my turn. When I missed, then I would give him the coordinates to position his balls and take his turn.
We’ve only had one session, but we think it is definitely viable and with more time using the system the ball positioning will become second nature and go smoothly.
Admittedly it is not as laser-precise as Caudron’s, but these games ain’t for the world championship, and ‘close enough’ is good enough for us.

Maybe you can connect with him and try it. I’d be happy to play when I get back. I’m glad Jason started this thread! Like him, not many folks to shoot with and long haul to rooms w/tables and players. This seems pretty workable- give it a try. Any suggestions are welcome.

Yup yup, I think it can work.

Is it easier than playing in person? Of course not, but the alternative is playing with nobody at all, so ...

jeagle, I'll shoot you a PM with my contact info if you wanna try in the next few weeks while Mac is out of town. I don't check AZB PMs very often, so email and phone may be best, if you're game.

What would be cool is an app that lays out gridlines over the table and beeps when it sense visually you've moved your ball into the right position.

I may futz around with that since in my experience coding skills come from coding towards a real goal, not just learning exercises in books.

That said, I don't expect it to be done next week or the year after

Ok, letís run with that, Jason. Ignoring cost for the moment, since you are a coder, how do touch screens know what youíve touched? Is that via some kind of XY grid sensor array? Could that idea extrapolate to ball positions?
Or, vision systems are getting quite sophisticated, maybe borrow something from them?

I think cost will be an issue, but ...

I've been talking through it with a buddy of mine who has written a ton of apps of all sorts and it seems initially like it the math, while tricky, can be accomplished but the image recognition of the ball will be the steeper hill.

There is probably most of the needed image stuff in Virtual Pool but it is a question of getting the developers interested in implementing "table capture".

A nearly working example is "Eagle Eye" used on snooker broadcasts to allow showing the player's view of the shot. Somehow they have not connected the image system to a ball placement helper. Instead the referees futz around seemingly forever to replace balls according to a previous screen capture compared manually to the current position from the same fixed camera. I think the Chinese broadcasters have a complete system.

But an alternative is to generate a set of semi-random positions that each player sets up and shoots. This was the way collegiate competition was done for a while, I believe. I think it was called a "key shot" tournament. That allowed competition without travel.

Interesting, thanks!

Yeah, I admit I've always been a bit underwhelmed by the Eagle Eye system. I usually say to myself, 'Geez, how hard can it be?'

Bu then, everything is easy to the guy who is not doing it.

Good options of which to be aware, thank you Bob. To me, the attractions of the approach weíre trying to work out are 1) we get real ball hits and feel, stroke practice on real tables, and 2) there is a social aspect with FaceTime. Not just a Ďgameí, but a chance to meet a new face and talk about more than just the game; itís a social experience. Iím tired of just shooting on an empty table. Itís nice to chat on the nuances of various shots.
