Abstract:The primary objective of this research is to widen the range of questions that can be addressed in small group planning situations. This can be accomplished through improved access to tools, media, and group cognition. While the range of addressable questions can be widened by integrating two or more of these information vehicles, typically one is utilized at the expense of the others. This is partially due to inadequate human-computer interfaces, information filtering and access difficulties, and the individual orientation of computers.
This dissertation provides a design for a hypermedia-based Collaborative Planning System (CPS). This system is designed to widen the range of addressable questions by implementing tools, media, and group cognition in a manner that minimizes conflicts among these information types. This is accomplished by addressing human-computer interface problems with representation aids, overcoming information filtering and access difficulties with an associative information structure, and finally, overcoming the individual orientation of computers with computer supported collaborative work.
Four implementations of the CPS are investigated to determine how individuals and groups interact with such systems. These were implemented in situations where groups were addressing questions regarding the St. Louis Riverfront, East St. Louis, Crawford County, Illinois, and a reuse scenario for Chanute Air Force Base at Rantoul, Illinois.
The CPS implementations demonstrated that the ability to address questions expeditiously can make it easier to pose related questions, thus facilitating a conversation among group members. Furthermore, the presence of either media or tools widens the range of questions that a group is capable of addressing through a reduction in the time required to access outside information.
Increased access to relevant information, aided by the implementation of a CPS, can ultimately lead to greater communication among participants in a group planning situation. This will ultimately have a positive effect on the quality of plans and decisions.
