Abstract: In an embedded system, for instance in a household appliance, in addition to the usual embedded microprocessor/microcontroller there is provided another processor which actually executes a user interface HTML document for accepting user input, for instance from a keypad and controlling the display device, for instance an LCD. The embedded microprocessor hosts the user interface document, responds to requests from the other processor, keeps track of changes in variables shared with the other processor, and executes the control device functionality. The other processor renders the graphical user interface to the display and interacts with the user by executing local functions to operate on the memory and i/o resources of the embedded processor as described by the user interface document served to it.
