I think sensing these by touch is the right way to go - but your copper tape solution will not work.

The copper tape will not last more than a week of use before it tears up, tears off, and so on.

I would use the metal bolt that holds the item to the wall to sense. People will have to put their palms flat to the rock to use it, and if you crank the sensitivity up high enough, it'll catch people from even a good distance. We've used touch sensors to go through empty air up to 2-3 inches.

I think that you are on the right track as far as how to achieve this. I do fear that the copper tape is not going to hold up well though. I wonder if a small metal plate could be built into the wall right above the hand holds. A lot of capacitive sensors are sensitive enough that even close contact would trigger the holds. I think this would hold up a lot better. Lastly, I do have some concerns about the number of I/O in this room. I would explore whether or not hand holds of the same color could be chained together to create significantly less inputs. I realize this would keep the secondary color gameplay from working, but I think it would mean it is much more likely to appear in an actual Open World venue someday. This is a great concept.

I think this concept is great. Climbing on walls of Jelly beans is just a fun concept.

You did a good job of identifying what the most difficult and risky part of this idea, which is sensing when someone is on a handhold, and trying to figure out if you could make it work.

You guys picked a good question to answer. Understanding how the handles work is crucial in making this experience work.

One of my concerns for the work's like model is the use of the copper tape all around the mounts. Is this tape, and the sensors, very durable or is it easy to peel off? Will putting tape all around the mounts detract from the color of the mount? How expensive are these sensors and how many mounts will you need? Will this become very expensive? Will people have to place their feet in a certain orientation and how will this be monitored. Will stepping on the touch sensors create false positives, and or damage them, as people climb the wall?

The concept explored is extremely valuable as it would how each contact would be registered.

I think you're on the right track, but keep in mind that people will be touching that tape a million times - and we want something that'll withstand that use without being fixed.

This is a great start to figuring out this design. I definitely recommend you keep pushing forward. I think this has a lot of potential. Nice work.

The execution of this works like is great because you used existing things, such as rock climbing hand holds, to quickly figure out how to sense if someone had touched a handhold.

The sketch model was demonstrated nicely in the video. The copper tape seemed to work very well. Does this work for the other colors too? Have you done any tests where purple is the color and the player has to touch blue and red? Besides that, great sketch model!

Great execution of the game with the Arduino code! It looks like it is reading the colors correctly from the video. It will be interesting to see how you implement the secondary color commands. Also it could be interesting to track specific players points for each of the moves and have a total points awarded to each player and a total for the team by the end of the game. Then players would be able to try the room again to get a better point value, instead of just passing it.

Great solution to how not to need additional equipment for the guests to equip to put on or use. I would be concerned about how extended use would affect the copper tape and the connection on the grips. Deals with the variety of color well and proves what they wanted to prove.
