ABSTRACT:
To reduce the number of processors and/or displays in mobile equipment, an operating system is emulated in one example. A primary operating system runs on a processor or uses a particular display. The emulated operating system shares the same processor and/or same display. The emulation allows use of applications drafted or written for different operating systems in a common or shared environment. As another example, a virtual terminal function is emulated on a particular device. The particular device interacts with additional sources of information for displaying images on a same display. Using emulated operating systems or virtual terminals, a navigation program is used in a vehicle. An additional program is run on the same processor or shares the same display in the same vehicle at substantially the same time.
