:: Jakob Nielsen on the usability of mobile devices ::
Jakob Nielsen is a recognised expert on usability. I have referenced his works in my forthcoming book "Next Generation Mobile Services". He has recently posted an observation about the improvements in usability in mobile devices, having used a T-Mobile Sidekick for the last 6 months (an integrated PDA/phone device).

"New mobile devices show a huge improvement over previous generations, but they're still not good enough to score a real win. To get there, we need both PC-integrated applications and specialised mobile services rather than repurposed website content."

:: Q12 - Another exciting keypad design ::
 It seems my previous comment to open up a channel just to discuss keypads was justified. No sooner had I said it than these guys at Softava emailed me about this exciting new design called Q12 (right). It uses the same principle I have already reported here that Unitap and Fastap use, namely deliberately positioning keys (“hills”) close enough together that pressing what appears to be the gaps (“valleys”) between them causes several keys to be pressed at once. This combination is used to generate the desired character, so in effect each valley is like a virtual key. Fastap and Unitap both use enough keys to represent directly the letters and virtually the digits. However, the Q12 takes this to another level and uses cleverly shaped keys to represent the digits directly and the letters virtually via all the various valleys sculptured in the keys (see the schematics on their website). It sure seems clever and I would love to try it out for real.
