Research interests

Major Artificial Intelligence and Language Technology Lab projects include

  • the Robot Baby - Here we aim to get a computer to learn it the same way a baby does, in a real or simulated world, learning about language and the world. Previous work focused on a robot baby/doll with a variety of sensors, microphones, cameras and motors combined with techniques for fusing information from different sources;
  • the Intelligent Room - A related application is an intelligent room with multiple microphones and cameras allowing tracking of speakers and homing in on the desired signal whilst canceling noise and echoes. A natural language/speech interface allowing control of home/office devices was commercialized by I2Net in association with Clipsal;
  • Talking Head -> Thinking Head -> Teaching Head - Now we are combining speech and language processing, auditory and visual reading of lips/speech and expressions/emotions with dialogue modeling in specific applications in a $3.4M 5 year ARC/NHMRC research project in collaboration with the University of Western Sydney, Macquarie University and the University of Canberra. The mobile project is being commercialized as Clevertar;
  • the Brain Computer Interface - Beyond the Speech Control Interface where we control devices by talking, we can also control devices by thinking! This work was initiated with Prof. Richard Clark and the Cognitive Neuroscience Laboratory which reported some of the very first results in this area. We are developing interfaces both to monitor the mental state of a person (e.g. stress, skill, fatigue) as well as for thought control of devices ranging from a cursor on the screen to a wheelchair;
  • Intelligent Search and Visualization - Information Retrieval and Web Search are the major current applications involving natural language and provide a challenging test for the techniques we are developing. Deep web research was commercialized as YourAmigo.
