Abstract

This article describes an operator interface to create, modify and control multiple windows for use in an interactive environment. This interface is intended for applications where window attributes, such as position, size, color, and contents, need to be changed after the window has been displayed. This interface would normally be a component of a larger presentation control system, such as the LS/1 Authoring System used in the examples.

Operator Interface for the Creation and Control of Windows

This article describes an operator interface to create, modify and control multiple windows for use in an interactive environment. This interface is intended for applications where window attributes, such as position, size, color, and contents, need to be changed after the window has been displayed. This interface would normally be a component of a larger presentation control system, such as the LS/1 Authoring System used in the examples.

A wide variety of menu-driven window creation packages exist that permit a user to create windows interactively. Normally, these only create a static, or unchangeable, window that cannot be altered at execution time by the user without technical programming assistance. In the education environment, for example, the initial user may be a sub

The interface and program described here permit such an author to create windows containing text, input, output and select fields, and possessing the attributes of color, size, etc. These attributes may be assigned when the window is created, or changed dynamically during presentation to the student. To change the window during presentation, the author would save action commands that act upon the window at a later time. These action commands are stored in a list or script that may be edited by copy, move, add or delete action commands. The list of commands is then executed for presentation to the student. This permits the author to "animate" the window via changes in attributes of color, position, etc.

The selections menu shown in Fig. 1 displays the primary controls for creating the window and entering the action commands.

New windows may be created or existing windows may be imported from external window libraries. The windows may be sized, moved, colored and cleared of text. Each of these actions creates a command that is stored in the action list for later playback. A fully finished window may be displayed by the Enter Window command. The selections across the top provide access to pull- down menus, enabling more selections.
