Cause and Effect Sensory Sound Box is a developmental touch skills app. It was made for teenagers with complex learning needs including autism and visual impairment.
Sound Box is also a popular choice for parents of young toddlers without special needs who are beginning to explore touchscreen phones and tablets.
Each of the twenty-four scenes plays a continuous sound which changes it's pitch or intensity as one or two fingers move around the screen. Colourful abstract animations appropriate for any age-group complement the sounds closely.
Several colour palettes including high contrast variations for visually impaired users are provided. Background images can be customised and a live video feed from either camera can be shown behind the animations.
The app also supports touch-free play for cause and effect switch access, single tap and sound activation switch control using the microphone.
For more information on setting up your Bluetooth Switch or Keyboard see the information at the bottom of the Developer Website page.
