Abstract
The aim of this research is to identify affordance features of input devices and then try to see if they can be formularized by quantifiable physical properties of the device. A hypothesis in this research is that affordance features can be explained by their association with physical properties or phenomena which people have seen or experienced. If affordance features can be explained by physical properties and formularized, then it would allow designers to strengthen target affordances and reduce unwanted affordances for better design. Some experiment results show effectiveness and feasibility of our approach.
