Using Mobile Code Interfaces to Control Ubiquitous Embedded Systems
Kari Kangas and Juha Röning, University of Oulu
Abstract
Devices controlled by embedded computers are becoming an integral part
of our everyday life, as processor and memory capacities continue to
increase while their cost decreases. In some embedded systems, however,
the limited input and output capacities are beginning to restrict the
design of complex functionality. Furthermore, as wireless communication
devices are becoming commonplace even in embedded systems, the
communication and interoperation between different systems will be
increasingly important in the future. This paper describes a flexible,
yet powerful concept that explains how a mobile code can be conveniently
utilized by mobile users to control ubiquitous and diverse embedded
systems in different environments. Apart from providing flexibility, the
concept also aims to keep the embedded systems as simple as possible. We
will illustrate the concept by presenting as an example a virtual user
interface for a videocassette recorder. We will also discuss the
possible benefits and drawbacks of the system. The concept described
here can be extended to allow the mobile code to be used as
interconnecting "glue" in diverse embedded systems. This glue could
connect systems from several manufacturers to create smart environments
that can be controlled by a single simple device.
