Graphical displays in pwAPP are handled using HTML as the language for User Interface description, with all output and input moving from the local application as a modified HTML page.
Input flows through the HTML page, but moves directly to the application instead of to a web server.
In addition to applications that contain a User Interface, pwAPP also supports a flexible driver design that enables drivers for custom hardware to be loaded and made permanently resident in the system. Applications can then make use of the driver to talk to a custom peripheral to add functionality outside the scope of web browsing. All of these specialized applications can be created by the OEM using pwAPP without the need of additional Planetweb engineering resources.
