Well, yes, but I think you're all missing the point. When the spot changes color, any worker WHO IS READY can press the button. You're all slaving a mechanical finger to the spot; regardless of whether the operator is ready or not.

One part that got left out is, how often are these jobs presented? I've never worked on a piece work basis, but my impression is that they would be presented very fast. Fast enough that no operator could be ready every time for all them.

Another question is what else are these tablets used for? Since the operator apparently is not waiting for physical stuff to be delivered to the work station (as in sewing clothing together), is the work also done on the tablet? If so, that limits the hardware you can have hovering over the screen.

And of course, when all the operators have these goodies, then you are right back where you are now, taking pot luck.

Also, there are better web sites than this one for this kind of project. "element14.com"comes to mind. Search for "maker movement" for more contacts.
