Abstract

This article describes how to define sounds in an Online Presentation Development System (OPDS) and the method which allows sounds to be played either while waiting for a user keystroke or in conjunction with other processing. The Online Presentation Control Language (OPCL) is a programming language designed to create stand-alone online presentations. An information developer, typically a non-programmer, uses the OPCL's commands to specify document structure, displayable text, sounds, animation, and other parts of the presentation. The OPDS is a group of programs designed to create stand-alone online presentations. Online presentations include such items as product demonstrations, tutorials, and other programs in which the computer is used to present information.

Sound Definition and Usage in an Online Presentation

This article describes how to define sounds in an Online Presentation Development System (OPDS) and the method which allows sounds to be played either while waiting for a user keystroke or in conjunction with other processing. The Online Presentation Control Language (OPCL) is a programming language designed to create stand-alone online presentations. An information developer, typically a non-programmer, uses the OPCL's commands to specify document structure, displayable text, sounds, animation, and other parts of the presentation. The OPDS is a group of programs designed to create stand-alone online presentations. Online presentations include such items as product demonstrations, tutorials, and other programs in which the computer is used to present information. The OPDS consists of three tools: -the OP Compiler which converts the OPCL into object format, -the OP Compressor which formats and compresses displayable picture elements of text and graphic shapes, and -the OP Processor which loads and executes the object code with its corresponding picture elements. This information developer may use sound in conjunction with several commands. To do so, the information developer must first define a sound. The format of the Define Sound command is: .DS id freq/dur [freq/dur2 ... freq/dur128] where .DS (Define Sound) identifies the command. id is a number from 1-32. This is the number by which this particular sound will be referenced throughout the section. freq/dur is a pair of numbers giving the frequency of the tone to be played, and the length of time the tone is to be playe...
