One of the most recent Apple patents to come to light is one for a Virtual Keyboard in the shape of an Arc (Picture) which bears a resemblance to Microsoft's UMPC keyboard implementation (Picture).
The recent patent application offers more refinement to the earlier touch screen interface filings (Gallery).
The virtual keyboard is described as learning over time based on which keys are pressed more often and adjusting the sensitivity of those keys. "That likelihood is determined by the person's distance of touch from the closest key, as well as frequency of use."
Another patent that has received much attention recent is Apple's Integrated Sensing Display which was previously posted and discussed in January 2006.
