"Using the Wii Balance Board(TM) as a Low-Cost VR Interaction Device"
by Gerwin de Haan, Eric J. Griffith and Frits H. Post.
In this work we explore the use of the Wii Balance Board(TM) as a low-cost input device in virtual reality (VR). We combined and extended existing communication libraries such that the balance board's four separate pressure sensors can be used as input to a VR application. We provide a brief technical overview of obtaining and working with the sensor input. By processing the sudden and gradual changes in the sensor input values caused by pressing on the board, we are able to use the balance board for both discrete and continuous input. We discuss how this discrete and continuous input can be used to drive a variety of VR interaction metaphors. Using continuous input, the balance board is well suited for interactions requiring two simultaneous degrees of freedom and up to three total degrees of freedom, such as navigation or rotation. The discrete input is suitable for various forms of control input such as mode switching or object selection. Additionally we present some example VR applications that demonstrate some of the possible metaphors
