This volume investigates the fundamental constraints and potential advancements within interactive systems through the lens of human-computer interaction research. The ACM staff compiles peer-reviewed technical papers that explore how designers and researchers can identify, analyze, and transcend existing limitations in user experience and system functionality. The text serves as a formal record of the methodologies and experimental results presented at the 1999 CHI conference.

Experts and researchers view this volume as a foundational archival document for the state of HCI research at the turn of the millennium. The text is highly technical in nature and is primarily utilized by academics and practitioners interested in the historical development of interface design standards.
