About Addas Technology

Our method is based on a comparative analysis. We compare the eye-movement patterns of children suspected with ASD to the standard eye-movement patterns of children of the same age.

It is a proven scientific fact that eye-movement patterns and the visual preference of children with autism in response to specific visual stimuli differ from that of neurotypical children of the same age group.

About the device

The device is compact, easy to use for anyone. It contains a monitor, a camera, and an infra lighting element.

The product meets EU standards for health, safety, and environmental protection (CE). During the test the child sees a flatscreen, all the other parts of the device are hidden. The open sidewalls are meant to shut environmental stimuli out.

About the software

The device shows different stimuli to the child. ADS affected children react differently to these stimuli, they scan the images with their eyes in a different pattern.The analysis of the eye-movement pattern is carried out online, in the cloud.

The software compares the recorded data to a large reference database and send the results back to the user.

When a social scene (top picture) and a non-social image (bottom picture) are shown to children simultaneously, neurotypical children would exhibit preference for the image on the left, while their counterparts with autism for the image on the right.

Automatic calibration

The software calibrates itself in the first 2 seconds. For this we show a fish swimming from side to side of the screen which will stimulate the children to follow the fish with their eyes.

This way the device can record their eye position and calibrate automatically.

Examination process

Before every stimuli a fixation stimulus appears to draw the attention of the child to the center of the screen. This is monitored and recorded real-time.

The system shows 26 screening items in the categories of distraction measurement, static social preference stimuli, dynamic social preference stimuli, static face stimuli, dynamic face stimuli.

In the picture we can see a face stimulus with which we measure if the child focuses on the eye-area, the mouth-area or other parts of the face.

The detection of Autism spectrum disorder during the first years of life is hindered by the absence of an objective and non-manual measurement tool.
