Abstract : |
Today's interface design tools either force designers to handle a tremendous number of design details, or limit their control over design decisions. Neither of these approaches taps the true strengths of either human designers or computers in the design process. This paper presents a human-computer collaborative system that uses a modelbased approach for interface design to help designers search the design space effectively and construct executable specifications of application user interfaces. This human-inthe-loop environment focuses human designers on decision making, and utilizes the bookkeeping capabilities of computers for regular and tedious tasks. We describe (a) the underlying modeling technique and an execution environment that allows even incompletely-specified designs to be executed for evaluation and testing purposes, and (b) a tool that decomposes high-level design goals into the necessary implementation steps, and helps designers manage the myriad of details that arise during design., |
