Goals/Objectives:

  1. Design a multisensory stimulation delivery system to chart out sensory processing differences for infants

Outline:

MADCAP includes three main components: a multisensory stimulation delivery module consisting of audio, visual, and tactile stimuli, a multi-dimensional data capture module capturing a subject’s response, and a supervisory controller module to synchronize the interconnection between the two modules. The audiovisual stimuli delivery module was implemented by using Unity software, it delivers synchronized or asynchronized audiovisual stimuli. The tactile stimulus is delivered by a custom-designed tactile stimulation device (TSD), which is designed specifically for infants to deliver affective touch at precisely controlled brush speed and pressure. TSD communicates and synchronize with audiovisual stimuli through serial port. The Tobii X120 eye tracker is used to record the gaze position and the E4 sensor was used to record the physiological data while worn on the ankle. The following picture is the experimental setup of MADCAP.
