| Popis: | IVOrpheus is an information visualization tool for three-dimensional data that allows user's interaction by voice commands, mouse and keyboard input. The visualization technique used was the scatterplot 3D, which was implemented using Jmathplot API, and the speech recognition in Brazilian Portuguese was performed by Coruja software. IVOrpheus was developed in Java following the architectural pattern MVC, design patterns and open technologies. In voice interaction, some usability guidelines have been set in interface building process, making it more intuitive and contributing to lower the user cognitive effort. In addition, initial usability tests with users were performed to evaluate the application interface with and without interaction by voice. The tasks with and without voice interaction have shown similar results of time and completeness. The speech recognizer achieved a word error rate of approximately 17%. |
