Hi Anm,
Years of work worth reading your feedback, appreciate very much.
I am very interested what you say here:
"My concern is that the primary multi-touch gestures chosen are two handed.". I think that ultimately there will have to be a standard for handed, but an evolved set of gestures. I am working on that, you know why?
I strongly believe that there has to be a balance in terms of handed gestures to execute on what has been selected (our innovation, do a gesture on a selection). There will be a time when gestures have to evolve to cope with demanding tasks at home with multiple touch devices in almost all glass/crystal/plastic surfaces, so there is going to be plenty of need. New types of gestures that can be learned and reproduced fast. Nor the palm graffiti type nor the imagery type (pinch, stretch, and swipe). New types.
Something is in the middle that can be worldwide interpreted and very easy to execute, that is the key. As an example we created the Twitter peak ">" gesture cause is fast and symbolic. That creation process has to be applied many more times again for new gestures with an implicit action and a symbol. Also the key can be to synthesize the gesture to a minimal expression.
Also, once the user has done the gesture four times, the fifth goes on its own. So its all about learning curve. We humans have a great ability to remember mechanical movements. I would love to have a more consistent scientific background. Any doctor around?.
This is the way I think we can overcome the real problem and concern you are pointing out and that I agree 100%. Of course tablet will be a superb place to run PadKite.
Great feedback, really.
