ACCESSIBILITY FEATURES: All SPACE-TIME ADVENTURE TOURS are designed for accessibility and include features for non-visual gameplay for blind and visually impaired users as well as captions and haptic feedback for deaf or hard of hearing folks. To toggle the screen reader on or off: three-finger triple tap anywhere on the screen. This function is only needed to customize your access needs and start the tour from the main menu. It is not needed during the tour itself. In order to use our screen reader you may need to disable the Zoom magnifier. You can do this in Settings > Accessibility > Zoom. To help with navigating from stop to stop we have provided optional spatial audio beacons. These beacons emit a bell sound that corresponds with the next stop on your map. Headphones are required to unlock this feature. GPS announcements and verbal directions are also included to assist with way-finding. Interactive buttons and gestures have also been simplified and designed to be forgiving. For example, when prompted to press the “big red button” you can press anywhere on the lower portion of the screen. Please reach out to our access team to give any feedback on your experience. andy@fairworlds.com
