On the parameterization of Catmull-Rom curves
The behavior of Catmull-Rom curves heavily depends on the choice of parameter values at the control points. We analyze a class of parameterizations ranging from uniform to chordal...

Assessing the Effects of Orientation and Device on 3D Positioning
We present two studies to assess which physical factors of various input devices influence 3D object movement tasks. In particular, we evaluate the factors that seem to make the m...

Towards the coevolution of cellular automata controllers for chemical computing with the B-Z reaction
We propose that the behaviour of non-linear media can be controlled automatically through coevolutionary systems. By extension, forms of unconventional computing, i.e., massively ...
