This paper describes “Book Window” that we implemented, a window system based on the “book” metaphor, that displays information not by scrolling but by using the animation of paging through. The BookWindow system equips some bookmarks, tabs, etc., by ...

This demo shows the prototyping environment of the Ircam Signal Processing Workstation. The environment is oriented toward rapid prototyping of DSP and Musical applications.

Key findings from empirical studies—early design is opportunistic; critical role of pictures in design conception; impact of various cognitive limitations—have very effectively determined requirements and design for a set of tools to support early ...

Grace is an intelligent tutoring system for COBOL which has been used to teach both novice and experienced programmers. While the tutor was quite effective in several classes and was designed with cognitive and interface principles in mind, we discuss a ...

Most UI toolkits and UIMSs make use of widgets, e.g., buttons, text fields, sliders, menus. Designers construct user interfaces by choosing and laying out widgets, then connectimg them to application semantics. This approach has four problems. First, ...

Many tools create new user interfaces by compositing them out of smaller pieces. This usually leads to variations on the dialog box to edit a single composite object. Workspaces are a model for compositing together various editors to manipulate sets of ...

Building an interactive application involves the design of both a data model and a graphical user interface (GUI) to present that model to the user. These two design activities are typically approached as separate tasks and are frequently undertaken by ...

TAE Plus was built at NASA's Goddard Space Flight Center to support the building of GUI user interfaces for highly interactive applications, such as realtime processing systems and scientific analysis system. TAE Plus is designed as a productivity tool ...

This paper reports on the results of a survey of user interface programming. The survey was widely distributed, and we received 74 responses. The results show that in today's applications, an average of 48% of the code is devoted to the user interface ...

We have augmented user interface objects (i.e. windows, menus, buttons, sliders, ets.) with preconditions that determine their visibility and their enabled/disabled status and postconditions that are asserted when certain actions are performed on the ...

A fisheye lens is a very wide angle lens that shows places nearby in detail while also showing remote regions in successively less detail. This paper describes a system for viewing and browsing planar graphs using a software analog of a fisheye lens. We ...

An interface for software that creates a natural environment for engineering graphics students to improve their spatial reasoning and 3D visualization skills is described. The skills of interest involve spatial transformations and rotations, ...
