Scunnerball: An analysis of the motion characterstics of spheroids with high coefficient of restitution in tabletop interaction

The bizarre physical properties of rubber balls with extreme coefficients of resitution are well known. In this paper, we propose a novel interaction techinque based around the unpredictable rebounds of the balls. A situated game “Scunnerball” is developed via a user-centered design process. We show a number of studies identifying optimal layouts for Scunnerball games, and demonstrate empirically that the game is optimal with a number of players such that N (the number of players) is given by N ≡ 0 mod 2.
