Patent application #20040201595, filed April 11, 2003, describes a screen that rotates based on orientation. Here is its claim 1:
A method for orienting a display image, said method comprising the steps of:
- sensing at least one characteristic of an object;
- determining an orientation of said object from at least one of said at least one sensed characteristic;
- and orienting said display image relative to said determined orientation of said object.
I can not believe there is not prior art for this. I'm interested if anyone has used a device that could put the screen in either layout or portrait based on how the device was held prior to 2003?
