User Interface Management and Design

The goal of this paper is to point at some of the more important deficiencies of current user interface tools. Our point of view is an industrial one. Therefore, many of the requirements to user interface tools formulated in this paper are results from experience made with customers and real use of such tools. Let us mention already here the most eminent deficiency we currently see: the missing experience with the application of user interface tools, in contrast to the large number of tools that have been developed thus far. Also, it needs to be observed that workstations in office environments are not the only fieldwhere user interfaces exist. In detail we discuss the following areas: AI-inspired techniques, multi-media dialog, the evaluation of user interface and distributed computing.

Methodology of Window Management

An architectural model of a window manager is presented. Some commercially available window managers are compared in relation to this model. Specific attention is given to the window managers supplied by SUN, APOLLO, and ICL (PERQ PNX). 3.

Architecture Working Group Final Report

The Working Group’s discussion concentrated upon the following issues: (1) nomenclature for the objects displayed and manipulated; (2) levels of interface: especially the functionality of the client-server interface; (3) the input model; (4) responsibility for redrawing of portions of windows following damage or size changes; (5) hardware and operating system prerequisites.

Application Program Interface Task Group

This group was formed during the final plenary session on the second day of the Workshop and was charged with producing a set of conclusions about the application program interface. The group met for one two-hour session on the morning of the third day and then reported its findings to a plenary session. Membership of the Task Group was: James Gosling Paul ten Hagen Harold Thimbleby

Application Program Interface Working Group Final Report

A window is a region on a display surface whose size, position, and display priority relative to other windows may be changed at will by the operator. Different windows may vary in their appearance: presence of title bars, border style, kind of scroll bars, etc.
