Low Cost 3D Rotational Input Devices: the stationary Spinball and the mobile Soap3D
The 11th Symposium on Virtual and Augmented Reality (SVR), Porto Alegre, Brazil, May 25 - 28, 2009. Best short paper (bib)

This paper introduces a new approach enabling intuitive input of rotational data with low-cost optical sensors. Two devices are built, one for desktop applications and a mobile wireless device for everywhere use. The desktop variant, called Spinball makes the virtual trackball a real device. The mobile device, called Soap3D uses a two-layered approach for device casing, enabling closed hand control. Benefits and construction are illustrated and results of expert reviews are discussed.
