  This study proposes middleware, GameControllerizer, that allows users to
combine the processes of Internet of Things (IoT) devices, Web services, and
applications of Artificial Intelligence (AI), and to convert them into game
control operations to augment existing digital games. The system facilitates
easy trial-and-error development of new forms of entertainment and the
configuration of gamification by enabling the use of diverse devices and
sources of information as inputs to games. GameControllerizer consists of a
visual programming element that uses the Node-RED tool to allow users to
program easily to convert diverse formats of information into inputs to games,
and contains a game input emulation element whereby hardware- and
software-based emulation generates inputs for gaming devices. Evidence of the
usefulness of the system was provided by a performance assessment and the
proposal of a variety of use cases.
