As pervasive information systems weave their way into society, it is critical that these new systems are accepted and utilized. However, it is difficult to determine what makes for a good design and a successful interaction because evaluation methodologies and metrics are in their infancy for these types of systems. The complexity and diversity of these systems has made it difficult to establish common evaluation techniques and practices. However, the necessity for such a framework is overwhelmingly apparent. A framework will make it easier for researchers to learn from each other’s results, create effective discount evaluation techniques and design guidelines for pervasive computing, provide a mechanism for researchers to share what they have learned about the appropriateness of different evaluation techniques, and provide structure so that key areas of evaluation are not overlooked.
