This document discusses future trends in integrating natural user interface (NUI) technologies into broader game categories. It hypothesizes that NUI technologies can replace traditional game interactions by simulating all manipulations. The document outlines its goal of finding useful NUI technologies for broader game categories and methods for replacing or enhancing existing manipulations with NUI. It then describes conducting a qualitative literature review through online sources to collect and analyze data on technologies like eye tracking, speech recognition, and muscle-computer interfaces and their potential applications in games. The results suggest most game manipulations could be realized through combinations of these interfaces, though flaws remain. It concludes NUI technologies can be applied to traditional games with no interaction problems expected, except for online games
