“…Lunzer [1999] described the advantages in terms of the cognitive dimensions framework, arguing that subjunctive interfaces improve visibility (the ease of bringing desired information into view), reduce viscosity (the overhead incurred in changing something that has been specified), improve juxtaposability (the ability to view information side-by-side, important in making comparisons), and reduce premature commitment (a feeling of being compelled to take a decision without sufficient information). Other perspectives focus on the characteristics of tasks facing users in many current applications [Terry and Mynatt 2002b;Lunzer and Hornbaek 2004]. Those tasks, it is argued, frequently require nontrivial problem solving and have no fixed route to their solution.…”

Many applications require exploration of alternative scenarios; most support it poorly. Subjunctive interfaces provide mechanisms for the parallel setup, viewing and control of scenarios, aiming to support users' thinking about and interaction with their choices. We illustrate how applications for information access, real-time simulation, and document design may be extended with these mechanisms. To investigate the usability of this form of extension, we compare a simple census browser against a version with a subjunctive interface. In the first of three studies, subjects reported higher satisfaction with the subjunctive interface, and relied less on interim marks on paper. No reduction in task completion time was found, however, mainly because some subjects encountered problems in setting up and controlling scenarios. At the end of a second, fivesession study, users of a redesigned interface completed tasks 27% more quickly than with the simple interface. In the third study we examined how subjects reasoned about multiple-scenario setups in pursuing complex, open-ended data explorations. Our main observation was that subjects treated scenarios as information holders, using them creatively in various ways to facilitate task completion.

“…The Cloning function provided in C3W is based on the concept of the Subjunctive Interface [17,18] by Lunzer. The display and comparison of multiple scenarios provided in the Subjunctive Interface is useful not only for searching the Web information being discussed in this paper, but also in various other ways, including design and simulation.…”

SUMMARYIn order to support user information retrieval on the Web, a framework is needed in which a user can define various types of data links as necessary by extracting only the necessary components from a Web application and then create a new compound document. This compound document refers to a document that includes services and tools embedded in it. In this research, the authors propose a framework which allows for clipping the structural elements of a Web application and directly manipulating the data linkages using formulas. As a result, the user can clip these components into cells from different Web applications, and then by linking them, create a unique compound document. Moreover, the authors provide a framework for cloning the clipped cells in order to compare the results of various different searches. Furthermore, in this paper the authors describe a method to use a word processing document or spreadsheet as a destination for embedding the clipped components, and function linking for these documents and the clipped cells. As a result, the created custom complex document can be reused and shared more easily.

“…The cloning facilities are based on our work on Subjunctive Interfaces [11,12,14]. Computer users often want to compare alternative scenarios, but few applications provide good support for the side-by-side viewing that would facilitate such comparison; equipping an application with a subjunctive interface allows users to set up multiple scenarios, then view and control those scenarios in parallel.…”

“…We show how C3W allows a user to create a custom information-access interface based on one or several Web applications, then use this interface to view and control many alternative requests side by side. Providing support for such side-by-side handling is the central theme of our work on Subjunctive Interfaces [11,12,14]; C3W represents a substantial advance in this work, being the first system to make subjunctive-interface facilities available for a whole class of applications that normally handle just one request at a time. Section 2 demonstrates our prototype and explains its capabilities.…”

Many applications provide a form-like interface for requesting information: the user fills in some fields, submits the form, and the application presents corresponding results. Such a procedure becomes burdensome if (1) the user must submit many different requests, for example in pursuing a trial-and-error search, (2) results from one application are to be used as inputs for another, requiring the user to transfer them by hand, or (3) the user wants to compare results, but only the results from one request can be seen at a time. We describe how users can reduce this burden by creating custom interfaces using three mechanisms: clipping of input and result elements from existing applications to form cells on a spreadsheet; connecting these cells using formulas, thus enabling result transfer between applications; and cloning cells so that multiple requests can be handled side by side. We demonstrate a prototype of these mechanisms, initially specialised for handling Web applications, and show how it lets users build new interfaces to suit their individual needs.
