What do you think is going to be the next “big thing” in the future of touch technology? – Paul Jones, Santa Cruz, CA

Dear Mr. Jones: Now Touch Guy feels threatened! For many months he has been extolling the virtues of projected capacitive touch and now you think it might not be the good-for-everything solution. Ok, I will reluctantly look into the crystal ball, aka Touch International’s skunk works, to provide you the answers you seek. In-cell technology […]

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 […]

If I switch from a curved touch screen to a flat panel, will there be compatibility issues? Please Help! – Nicholas J. Kriz, Eden Prairie, Minnesota

Dear Mr. Kritz: It is your lucky day! If you had asked for a single curved 13 inch touch screen, the answer would be iffy, because Touch International made their last resistive touch screen in that size more than ten years ago and we only make a few curved surface capacitive sizes now. But you […]

How is TI’s new MulTI-Touch Projected Capacitive Technology able to work with water spray?- Tyler Womack, Wapakoneta, Ohio

So Tyler, I guess you know water can be a lot of trouble for touch screens. The most vulnerable is SAW which stops dead in its tracks, to the least vulnerable, resistive touch. Resistive can be sealed so that water does not get in between the PET and glass layers which allows for better performance […]

Is projected capacitive technology reliable when used outdoors in a marine environment where it will be exposed to rain, saltwater spray, bright sunlight, etc? What are the likely points of failure? – Charlie, Marblehead, Massachusetts

Hey Charlie: This is a most appropriate question for national sock burning day because, as is the case with all good sailors, Touch Guy barbequed his socks and pledged to go shoe-to-skin all the way to the last blustery days of Fall. Ah, but back to your question…Until recently, resistive touch was the only technology […]
