improving human interface drawing tool using speech, mouse and key-board

DOI

Description

This paper focuses on the utility of speech input. We proposed some principles of human-computer interaction, which consist of the basic principle and the organization principles of interface that are required for comfortable input systems. In applying these principles, we discuss the desired organization of interfaces using speech, mouse and key-board, and design a multimodal drawing tool S-tgif. We also verify the benefits of speech input by using the tool. It is shown that the multimodal drawing tool with speech recognition reduces the average operation time to 82%, the number of command inputs to 89%, and the movement of mouse pointer to 53% in evaluation with inexperienced users.
