Larry Slotnick, Chief Products Officer for PalmSource, has revealed this morning a significant initiative called "Project Rome." Project Rome is a new next generation user interface architecture designed to simplify user interaction on phones.
The new and revolutionary UI for smartphones is coming soon to phones via PalmSource, and is designed to handle interruptibility and smaller screens which characterize the situation faced by phone users. It provides order independence, so that for example, one can currently be on a call, and have the option to see a picture, and send it to someone. Or conversely, when someone is looking at the picture they can choose to send it. The idea is that whatever you are doing, you will find help in the UI to do the things that you might want to do next.
The UI also features single hand operability and supports devices that may not have a touchscreen. It will appear next year in the form of a product.
