Magic Cap (short for Magic Communicating Applications Platform) is a discontinued object-oriented operating system for PDAs developed by General Magic. Tony Fadell was a contributor to the platform, and Darin Adler was an architect.
Its graphical user interface incorporates a room metaphor, where the user navigates between rooms to perform tasks, such as going to a home office to perform word processing, or to a file room to clean up the system files. Automation is based on mobile agents but not an office assistant.
