IVOrpheus 2.0-a proposal for interaction by voice command-control in three dimensional environments of information visualization

Abstract

Several studies point out the importance of interaction in Information Visualization (InfoVis) field to the success of good data visualization. The interaction researches in InfoVis have encouraged the use of non-conventional interfaces, besides the traditional keyboard and mouse, such as voice commands, gesture controls, among others. This work aims to present aspects of design, development and evaluation of an interface for voice commands to interact in InfoVis 3D applications. The InfoVis technique used as usage scenario is the 3D Scatterplot. In addition, for speech recognition is used Coruja Software, to support Brazilian Portuguese. Finally, usability tests will be presented for a first evaluation of the interface and interaction proposal. The tests used the approach of user tasks to evaluate InfoVis sub-tasks. And as qualitative measurement is used NASA Task Load-Index methodology, which identifies the user’s total workload in the different tasks performed.
