上游充通大学 SHANGHAI JIAO TONG UNIVERSITY Sharpen the Design Goals Location-based input Input depends on user location Input depends on the direction where the user looks ("egocentric systems") Multi-modal input The input comes from more than one input device Dynamic connection Contracts are only valid for a limited time Is there a possibility of further generalizations? Example:location can be seen as a special case of context User preference is part of the context Interpretation of commands depends on context Software Engineering
Software Engineering Sharpen the Design Goals Location-based input • Input depends on user location • Input depends on the direction where the user looks (“egocentric systems”) Multi-modal input • The input comes from more than one input device Dynamic connection • Contracts are only valid for a limited time Is there a possibility of further generalizations? Example: location can be seen as a special case of context • User preference is part of the context • Interpretation of commands depends on context
