A design evaluation of a user interface for tending long-term tasks

Abstract

Organizational processes often take place over long periods of time and require intermittent attention. Remembering and reasoning about upcoming process tasks is important, but not adequately supported by existing tools. This paper describes Longitude, a tool that provides a compact timeline of tasks and deadlines. We discuss findings from an exploratory study of the system and propose new requirements for tools that help people participate in long-running group processes requiring intermittent and sporadic attention.
