The ‘React Trigger System’ is our flagship assistive technology, providing automatic access to accessible communication and information both audibly and visually. This App (React Trigger System / React) is one component of the React Trigger System, that also comprises a radio key fob and push-button to trigger ‘talking’ electronic digital display signage. The system makes electronic digital display signage accessible to all. The App makes digital display signage ‘talk’ and announces its visually presented information, providing the option for discrete in-phone audio and visual. Where a physical electronic digital display isn’t provided at a location, a React battery-powered Beacon can be provided to offer the in-phone delivery of audio and visual information for wayfinding, orientation and information that would traditionally be upon an electronic digital display or static signage. Although initially designed for the blind and visually impaired, the App is suitable for all and may be configured to encompass other needs such as hearing loss or physical mobility delivering information for all and triggering ‘actions’ from integrated third-party systems. *Where supported by the electronic digital display/signage or a React Beacon is present.
