Zac Browser was developed by a grandfather of a child with autism to address sensory issues children with autism experience with traditional browsers, such as unexpected pop-ups, sounds, and flashing visuals. Zac Browser provides a consistent interface with soothing navigation, large icons, and locked full-screen browsing of pre-approved websites. It offers educational activities and safety features to allow children with autism an enjoyable computer experience. The document recommends Zac Browser as a free software tool libraries can provide to benefit children with autism.
