The smart interactive 3D Product visualization is using X3DOM, and it is running with common desktop PCs as well as with touch devices. See an example video here.
iOS was one of the first mobile operation systems which provided support for WebGL and we worked hard to ensure X3DOM runs on those devices. However, WebGL was not switched on by default in the standard Safari browser. This changed with iOS8 which fully supports WebGL and is available right now as developer beta.
