This paper explores advantages and challenges of specifying how IoT data is presented to an end user in AR using HTML5. Our conclusion is that HTML5 is a way of defi- ning data where competence is easy to come by and cross platform usability is good. The primary advantage is the capability of deciding how something is rendered and have it look the same way on any number of different platforms. The challenges are that cross platform compatibility is not perfect. Even platforms such as a native Android application, that has support for rendering HTML, suffered from very poor performance compared to a PC. Platforms not supporting HTML5 natively, in this case Unity and Vuforia, caused further challenges and required a separate headless browser application to render the web page. Our conclusion is that you can use HTML5 to define the appearance of data visualization across multiple platforms, even though they may have no native support for rendering the DOM. It worked without issues within a browser running on a PC, came with performance issues inside an Android webview and required additional middleware and limited interaction in Unity. |
