Accellerator ideas for N95 and other phones

I just considered that a accellerator might be better than an touchscreen. Why?

I had a P900 of SE, Palm Vx and still own a Dell Axim X51v organizer. My experience is that touchscreens are extremely versatile input devices but using a pen really sucks. The iphone concept of using it for menu navigation and media browsing is just great. But mini qwertykeyboard are better at textinput and accellerators could be used for menu-navigation one-handed. A touchscreen needs a twohanded aproach. Besides a accellerometer does not smudge the screen: So what could we do with the accellerator:

Phone control options:

- In a menu mode tilting the phone navigates the menu items.- shuffle your playlist by shaking the phone. Skip the number: circle clockwise, replay the last number circle anticlockwise.

- refuse a call? Shake the phone angry. Accept? Turn it along it's long axis.

- Mouse or pengestures for quick application access become phone gestures (waving the phone in a complicated pattern starts your apllication). Write a B for enabling bluetooth. Do a special gesture and unlock your car, frontdoor or control your stereo.

Other options:

- Autorotation of the screen

- Step counter for counting walking/running steps. Adjusting music selection to fit your motionspeed.

- Use the phone accelleration and stepcounting to improve GPS resolution when walking between tall buildings.

- Use the phone accelleration to detect U-turns in car-navigation.

- Make the phone say 'ouch' when treated roughly. Shout for help when in zero G (freefall).

Any other ideas? Post them ;-)
