Abstract: An interleave module interleaves training and task support to assist a user to complete a task while simultaneously providing training to the user. The interleave module helps the user work towards a desired state using a task knowledge base while interjecting appropriate training based on need, the user's mental state and timing constraints. The interleave module may use a variety of input sensors for a subject and the agent to help determine actions to be taken to achieve the task goals and the user's mental state for training.
