3D input for 3D worlds
Sreeram Sreedharan, Edmund S. Zurita, Beryl Plimmer · 2007
Virtual Worlds present a 3D space to the user. However, input devices are typically 2D. This unnatural mapping reduces the engagement of the experience. We are exploring using Wii controllers to provide 3D gesture-based input to the 3D virtual world, Second Life. By evaluating its usability, we found that gesture-based interfaces are appealing and natural for hand gestures such as wave but difficult to map to facial expressions.
