This talk will cover the development of the THOTCON 0x9 badge and explore various challenges, opportunities, and design considerations faced when creating a game experience for custom-built embedded, interconnected systems. It will explore these topics through the use of the THOTCON 0x9 and 0x8 game badges as case studies in hardware and software development, as well as human-computer interaction and game design. We'll touch on the design of these systems, and highlight material differences between both software design, and the design of physical artifacts. We'll also talk about making games!
