A good, quick general overview of AR and it's applicability to data visualisation in IoT/IIoT. Further examples of AR authoring software (SDKs) that could have been mentioned: Unity 3D, Wikitude, Kudan, EasyAR, and especially opensource ARToolKit, which has been around for close? to 20 years.
In the limitations of AR section, especially in industrial or field applications, a mention should be made of user immersion phenomena, and user immersion mitigation methods.
