Native HTML Support:

As a HTML developer you can now use the native WearML API in order to optimize your Website or Web Application.

This new feature now gives the ability to add WearML descriptors to HTML code. Traditionally optimizing HTML for the HMT had involved using a JavaScript library or plugin’s for Cordova/similar frameworks, by injecting JavaScript into a WebView. HTML Developers can use the HTML attributes placeholder and title for input HTML tags to create voice commands and/or WearML descriptors.
