Josh takes an-depth look at the navigation design implications of touch/keyboard hybrid devices, coming to a similar conclusion as Luke and Jason:
Unfortunately, the top-of-screen navigation and menus of traditional desktop layouts are outright hostile to hybrid ergonomics. Tried-and-true desktop conventions have to change to make room for fingers and thumbs.
Want to test for a hybrid device? Tough luck. Instead, argues Josh, the best you can do is assume that any device visiting your site could be touch-enabled.
Luke and Jason have done some excellent research (and put together some demos) into how the placement of navigation could be optimised for touch screens of all sizes. Turns out that the “standard” convention of having navigation along the top is far from ideal on a touch-enabled device.
The next time you make a sandwich, pay attention to your hands. Seriously! Notice the myriad little tricks your fingers have for manipulating the ingredients and the utensils and all the other objects involved in this enterprise. Then compare your experience to sliding around Pictures Under Glass.
The premise of this work is simple: I meet two or more people on the street who are strangers to each other, and to me. I ask them if they will pose for a photograph together with the stipulation that they must touch each other in some manner. Frequently, I instruct or coach the subjects how to touch. Just as often, I let their tentative physical exploration play out before my camera with no interference.
If, like me, you were going cold turkey on Mobile Scrobbler after updating your jailbroken iPhone/iPod Touch, you can stop sweating now. The official Last.fm app is really, really nice ...and it's free.
