Where do I buy or how do I make a touch screen overlay (if thats the correct phrase) for a wide screen TV or laptop? Answered

I'm thinking about building this https://www.instructables.com/id/Robotic-Drink-Mixer/ instructable. However, I would like to get a feel for how it would act in a real world scenario and from what I have seen, many applications like this are run on a touch screen PC.

I'm pretty sure that if I do this I am going to use something touch screen but I'm open to alternative idea's if anyone has one :P

Thanks in advance.

If you're an experienced solderer, you could use the kit at this website 

Also there are plenty of other things like it on Google. The search that yields the best results is "Usb Touch Screen Panel Kit"  Good Luck, and happy Modding.

As I said, buy one off the shelf then.

There are specialist suppliers for such things - you can find them on line., or you can use the so-called frustrated internal reflection method. Here's one link of hundreds to "multi-touch" touch screens.

With great difficulty. Your best option would be to scan the TV screen face with infra-red light and sense where the beam is broken. Details - I leave to your skills.
