Here are screenshots from a touch screen web application for orthopedic clinics. The application controls were done with Macromedia Flash and the displays used xml data transformed with xsl. Positioning and styles are from a CSS stylesheet

 These are touch screen sytems, so the controls are big enough for a fingertip. The reason the navigation is on the right is an interpretation of Fitt's law*. The basic idea in Fitts's Law is that any time a person moves pointer,(in this case a finger or pen) certain characteristics of objects on the screen make them easy or hard to click on. The farther the person has to move the pointer to get to an object, the more effort it will take to get to. It means that the easiest objects to locate and target are the ones closest to the mouse's current position and that have large target spaces, also the users arm won't be in the way when using
