SpikeNav: Using Stylus Tilt in Three-Dimensional Navigation

We propose a new method for 3D navigation using a commodity stylus and tablet already in common use among 3D artists. SpikeNav exploits tilt sensitivity to provide a more direct interaction style. Conceptually the stylus is turned into a spike which the user can jab into the model by contact with the tablet; moving the stylus drags the model around and tilting it rotates it naturally, making the stylus a temporary handle for integral direct manipulation. Pressure triggers a mode switch between rotating and dollying along the view direction with tilt, conceptually using the stylus as a lever instead. Keywords: pen input, interaction techniques.
