Choice and Comparaison Where the User Wants Them: Subjunctive Interfaces for Computer-supported Exploration.
Aran Lunzer · International Conference on Human-Computer Interaction · 1999
There are many kinds of computer systemthat are intended to support users in performingan exploration among a range of possible results.However, such tools often allow only narrowprogress through the result space, forcing users totrade off the breadth of search they would like topursue against the time and effort required. Theaim of the ‘subjunctive interface’ concept is tomake broader searches more manageable, by lettingusers propose multiple alternative values for eachparameter where normally only a single value canbe supplied, and by supporting the viewing andcomparison of the various resulting outcomes.This paper clarifies the motivation andprinciples underlying the subjunctive interfaceconcept, describes implementation work thatillustrates the approach, and outlines directions forfurther pursuit of this research.Keywords: user interface, interaction styles,interaction techniques, cognitive dimensions,subjunctive interface, parameter exploration, medicalimage segmentation
