In order to construct a design methodology for intelligent information systems with high affinity to humans, it is crucial to understand the basic principles of human cognition and behavior, that are, embodiment and sociality.
In this research, three methods are used: (1) behavior/learning experiments using humanoid robots: (2) cognitive neuroscience based on brain activity measurements: and (3) experiments on human-robot interaction using " androids", new type of robots with perfectly human-like appearance. Through these experiments, the principles of human cognition such as embodiment and sociality are revealed from the three view points: robot, human, and the observer. The following results are obtained:
1. Principles of action generation/recognition based on embodiment: Using an adult-size humanoid robot, the dynamic " roll-and-rise" action was realized for the first time in the world. This revealed the effect of embodiment on autonomous behavior. The same principles are also shown t
o be in effect for action recognition.
2. Development of androids with perfectly human-like outlook and their application to interaction experiments: In order to investigate a fundamental factor of human social interaction, namely the effect of outlook, androids with perfectly human-like outlook have been developed and demonstrated to the public. Furthermore, methodologies for realizing natural bodily movements for interactive dialogues have been developed.
3. Principles and models of interaction: Brain activity measurements, looking time measurements and gaze measurements have been carried out on human subjects in dialogue situations involving either of human, android, non-humanoid robot, or simple machine. The experiments revealed how social cognition and attitude of the subjects change and develop for different targets. Also, a learning computational model which integrates autonomous embodied behavior and basic sociality, that is, imitation capability, was constructed.
The above achievements have received outstanding international evaluation for the international publications and conference presentations. Furthermore, parts of the achievements have been featured in TV reports and newspapers, widely provoking interests from the public. Less
