| The research goal of the PhD is to provide a computational model and an animation framework which allows real-time, reactive motion adaptation to changes both in the environment and in the physical and mental state of the virtual human in question. Constraints on usage of modalities and characteristics of motions, may be in conflict, are to be met. The motion adaptation is to be controlled by high-level parameters. The results of the work will allow authoring a range of virtual humans with different motion characteristics, and endowing them with subtle, reactive motor behavior. |
