dcterms.abstract | An audio trigger device has a number of buttons that can be depressed to create different audio signals with 5 different features. The audio signals are used to remotely control a computer running slide presentation software that has an audio channel to collect sound signals. The features of the audio signals are detected by the computer as commands for controlling the progress of the slide presentation by simulating keystrokes, mouse actions, or their combinations for the control commands of the presentation software. | - |
