A research agenda for highly effective human-computer interaction: useful, usable, and universal

Foreword: The ACM SIGCHI (Association for Computing Machinery Special lnterest Group in Computer Human Interaction) community conducted a deliberative process involving a high-visibility committee, a day-long workshop at CH199 (Pittsburgh, PA, May 15, 1999) and a collaborative authoring process. This interim report is offered to produce further discussion and input leading to endorsement by the SIGCHI Executive Committee and then other professional societies. The scope of this research agenda included advanced information and communications technology research that could yield benefits over the next two to five years.
