Here is the presentation that was held by UIQ Technology at the Symbian Smartphone Show 2008 in London.

It is very detailed and very informative overview of the touchscreen technology as well as different styles of the touch based user interfaces and if you would like to learn more about the technology behind touch user interfaces, limitations, opportunities and the future of touch user interface you should get it.

I really enjoyed in all 77 slides and I would highly recommend it to anyone who is interested in touch technology, developers as well as the end users.

Download it and enjoy in UIQ’s “tour through the mobile evolution” and don't forget that best parts of this technology will be ported to Symbian Foundation platform!

Presentation was the part of the 'Designing Touch-based User Interfaces for Mobile Applications' workshop. It was presented by Matthias Reik, who was one of the key architects of the UIQ platform and Fredrik Sjölin, Senior Interaction Architect of the UIQ platform. Take part of Matthias Reik’s and Fredrik Sjölin’s skills and experience and enjoy their “tour of the mobile evolution”

  • Resistive vs. Capacitive Resistive Capacitive Pros: Pros: Low Price (~$1) due to competition Very high durability (depending on the High Resolution cover material) Small-target activation No optical loss (longer battery life, higher contrast) Not affected by dirt, dust, water or light Multi-touch (depending on the controller) Good for finger touch Cons: Cons: Image clarity Higher costs, but now rapidly dropping from Durability (PET plastic front) $6-10 to $2-3 Not good for finger touch No stylus (not good for handwriting recognition). 29 October 2008 | 13 | UIQ Technology AB 2008.
