Use an optical tracking mechanism ( ie optical mouse sensor - or make a digital camera sensor do double duty ) to let the user view a larger virtual screen using a small PDa or cell phone display. It would be like my grandmother using her magnifying glass to read the newspaper ;) Lift to zoom out!

baked. not optical, but there is a prototype PDA that allows you to move around a larger screen area by simply moving the PDA. |

. . . using accelerometers. |

Baked in research [link] although unfortunately the paper and videos have been removed pending publication and after a heavy slashdotting. |

ISTR reading the paper when it was available and it described scrolling and zooming UIs very much as the idea here describes. |

The above comments are WRT the DEC Itsy, I believe (see link). |

The idea here is to combine actual motion of the device (not tipping it) with moving a virtual window over a larger virtual document. |
