Portable Eye Movement Feature Collection Device for Children with Autism

Eye movement data has become an important char-acterization in the analysis of children with autism spectrum disorder (ASD). Current eye movement measurement meth-ods require specialized expensive equipment, calibration, and trained personnel, limiting their use in general ASD screening, especially in resource-scarce environments. Therefore, collecting eye movement features based on the standard RGB camera of a mobile phone or tablet has many advantages over professional equipment. The system design is based on the Android tablet design, and the screen is divided into two parts to display the normal children and the ASD children paintings. The eye movement data of children is obtained through the front camera, so as to provide data support for future data analysis. Taking the different cooperation degrees of children into account, two collection modes are designed: 1) directly displaying the stimuli in a loop (image mode); and 2) providing the background video interspersed with the stimulus display (video mode).
