DISCUSSION Lessions Learned It does not take a very complex system to create behaviours that add a lot to the realism of avatar interaction. However, refining the behaviour is something that currently relies on crude heuristics and iterative design, rather than deep understanding of human actions, so there is always something missing. The prospects of this system encourage further work. Future Direction Make the balls become avatars of actual users and incorporate real time communication, first through text, then using speech. Look at different ways of controlling the behaviour of the avatar. The sliders could be affected by any kind of input devices and sensors. How can this become more intuitive and rewarding? Give the balls a body and contol gesture. Gesture would have to be tied to the information content of the message being conveyed. How can the relevant content be extracted from the user's input. Study more complex situations with more participants. Personalize the behaviour through learning. Maybe the user can show the avatar how to react in certain situations. Finally: This project has served as a good basis for my future work towards a Master's thesis by highlighting areas that require attention, indicating good prospects and given me tools to work with.
