Towards an approach for multi-device interface design

This paper proposes an approach for multi-device interface design that extends pre-designed interfaces keeping the original application conceptual model without loosing its usability, The proposal reinterprets general aspects of well known Human-Computer Interaction (HCI) lifecycle models and can be extended to the design of any interactive product. When validated through a simple transformation between a large and a small screen interface in an HCI domain, it shall point to a much less maintenance cost/complexity and a better usability, ensuring the user's satisfaction.
