The issues of this thread overlap what I am planning to talk about in Denver next month, so I wonít comment.
However, your point on virtual keyboards is interesting; Iíve been experimenting with free42 on the HTC touch pro 2. On this device and other latest gen handsets (like iphone), the calculator appears on screen almost life sized Ė at least big enough to actually press the virtual buttons with your finger.
One of the big drawbacks is that you canít feel the keys. Consequently, Iíve been trying to get some tactile feedback going with the virtual keys. I donít know if the iphone version does this, but itís fairly effective (compared to nothing!). Phone people like to call it haptic feedback, but its not really because true haptic feedback involves fingertip sensation (would be nice to add!).
What Im doing is wiggling the vibration mass inside the phone. Iím picking a number for the duration that gives it about 1 spin or so. For me, its 25ms, for other handsets it could well be different.
Anyway, this is a real step forward for virtualised keyboards. It would be even better to have special hardware, like a mass that could move forward and back rather than rotate.
if youíre in Denver, I can show you and that goes for anyone else interested.
