Using IoT-Type Metadata and Smart Web Design to Create User Interfaces Automatically

The advent of the Internet of Things has generated loads of data from the devices that are now connected to the Internet. While the majority of the data corresponds to measurements done by these devices, there is a second type of information (the metadata) that provides information about the devices themselves. Most of this metadata is still underused when used at all. On the other hand, the graphical user interfaces that allow operating and/or monitoring the connected devices from a computer or smartphone, are usually programmed from zero. However, the metadata that describes the main properties of the devices (i.e., inputs, outputs, precision, range, etc.) can be used along with smart web design techniques to automatically create these interfaces. This article proposes a framework to achieve this, and presents an application example consisting of an online lab of a servo-motor.
