Google just annouced
the Open Handset Alliance to create an open platform for cell phones.
This new operating system should include Google Applications (GMail, YouTube ...)
But how to browse those large pages, Google Maps for example, using such a small screen !?A possible solution for future cell phones could be to add a motion sensor (as already available in the optical mouses) to trigger the scrolling of the page (in the opposite way !!)
It is easier to explain with a drawing:

With this feature, we could get the feeling that we move a kind of magnifying glass over a virtual unlimited document.
What do you think of it ?Furthermore, if we add a sensor in a 3rd dimension (depth), we can also control the zooming factor.
