Types of Multi-touch Overlays available (or will be)
What are some of the multi-touch overlay’s that are available? And how many simultaneous points can they register (which is pretty important to distinguish between them). It seems that many multi-touch product specs don’t mention anything about how many points they can register simultaneously. Many of them are only 2, which is a pretty low number. It seems they try to hide this fact of something and I kind of find it misleading to omit such information from the specs. Is there a compiled resource somewhere that someone may have made that gives these types of specs and the technology they use, like whether it works in the sun, etc. Not that manufacturers say their's doesn't but some claim they work outdoors (which I guess they don't get messed up by IR like other technologies). Thanks.
