USER INTERFACE / ENTERTAINMENT DEVICE THAT SIMULATES PERSONAL INTERACTION AND RESPONDS TO USER'S MENTAL STATE AND / OR PERSONALITY

An interaction simulator uses computer vision, and inputs of other modalities, to analyze the user's mental state and/or personality. The mental state and/or personality are classified and this information used to guide conversation and other interaction. In a chatterbot embodiment, the substance of the conversation may be altered in response to the mental state and/or personality class, for example, by changing the topic of conversation to a favorite subject when the user is sad or by telling a joke when the user is in a good mood.
