This study investigates the impact of manipulating image luminance and spatial frequency on eye gaze and verbal behavior in autistic children. It explores a digital filtering technique to reduce distracting image characteristics, comparing baseline images to filtered images in 11 autistic children across two sessions. Results indicate that luminance in non-salient areas affected both eye gaze and verbal responses, though in opposite ways. The interaction between luminance and spatial frequency in areas of interest was also significant. This is the first empirical study to design assistive technology aimed at augmenting global processing at sensory-processing and social-communication levels.
