Scott, you get one question and one bonus question all rolled into one Touch Guy answer. With more than 50,000 iPhone touch screens being replaced per month with cracks, broken touch screens have become a big business so we kinda like the breakage. But I guess a broken screen keeping you from your Facebook page … Continue reading »
When evaluating a touch screen for a hardened handheld product (the system must survive a 3-5 foot drop onto cement, and cleaning with alcohol and water), how does resistive multi-touch compare with projected capacitive, particularly for gloved hand (1-2 layers of latex or nitrile), multi-touch and gesturing GUI’s?
My engineers claim gestures on multi-touch resistive do not work nearly as well as they do on projected capacitive (PCT) used in a variety of consumer devices, like the iPhone – why is this? Have there been any recent breakthroughs with resistive multi-touch? I would appreciate any new input on this subject.
Hi Alex: When you are comparing iPhone/iPad projected capacitive (also called PCT or P-Cap) to any other (even identical) projected capacitive sensors, you may not find the performance to be as good as Apple ’s product. How can this be? It is because Apple has had a really big head-start (as in years). You and … Continue reading »
I’m kind of new to the touch screen world and am trying to figure out why it is so difficult to get large (over 22”) multi-touch resistive and projected capacitive touch screens. Also, what are the big advantages and performance differences between the competing multi-touch technologies?
Hi Jim: So you want to know about big ‘uns? Projected capacitive, our favorite multi-touch technology, has pretty much topped out at 32 inch diagonal sizes. There are bigger ones available, but they have those annoying little wires that nobody likes to see. In the realm of large format multi-touch, we find that infrared, camera … Continue reading »
What’s the difference between resistive multi-touch and projected capacitive multi-touch and why would someone choose one over the other?
– Mike Zimmerman, South Carolina
Dear Mike: I am the long-time cheerleader for projected capacitive touch technology, so my answer may be biased, but here it is: If you are a mechanic using a touch screen to fill out an overpriced car repair estimate, you should use resistive multi-touch touch screens (MARS); everyone else should use projected capacitive multi-touch technology … Continue reading »
