With standard touchscreen interactives AM recommends the use of web application frameworks such as HTML, CSS, Javascript (React), etc. For any interactive needing image pinch to zoom please discuss with your AM digital contact.
For more bespoke interactives, especially those needing hardware integration, cameras, projectors or multiple interfaces AM is open to vendor recommendations. In the past applications have been built using Unity, Touch Designer, Unreal Engine and MadMapper.
