This course will explore how video game engines can influence the perception of spatial environments through the examination of interactive spatial software, such as the Unreal and Unity gaming engines, along with a critical reading of the history of gamespaces. Students will begin by developing interactive gaming experiences based around existing architectural precedents to deliberate the efficacy of these interfaces and engineer spatial techniques that are specific to address the latent potency of this medium for architectural exploration. After this initial period of research and analysis, students will embark upon their own efforts to use the gaming engine as a tool for designing and developing experience through the creation of architectural effects. The course requires a laptop computer capable of running the free UNITY game engine (www.unity3d.com) and the free Unreal Engine 4 (www.unrealengine.com). This class engages the act of "level design" in game design terms to create architectural spaces for interaction. This semester the class will research the emerging tools tackling Virtual Reality and Augmented Reality. We will examine the current and future offerings in terms of hardware and plugins to enable these experiences, most specifically Oculus Rift, Leap Motion and Qualcomm Vuforia, in order to propose a final project most relevant to the emerging technologies.
