Abstract: A system of sensors integrated into toys for monitoring free play activity of a human subject wherein patterns in play activity automatically are weighted into a pattern for identification of behavioral milestones, developmental progress and/or behavioral disorders. Specifically, accelerometers detect movement of toys which determine: (1) if the toy is being played with; and (2) the intensity in which the toy is moved. Pressure sensors detect the level and location in which a child may hold a toy. Synchronized with an audiovisual record of the play therapy session and a computer-generated avatar representation of the physical object, this data is integrated to find peak levels of behavior giving clinicians more efficient analytical tools.
