Inspired by the notion of synergy, the sharing of signs between tangible and digital artefacts, we explore signs created by students that emerge through their use of TouchTimes (TT), a multitouch iPad application. We use Peirce to study the tripartite function of the signs (symbol, icon, index) available, as a way to study potential synergies in TT, and how they compare to signs found in other visual models of multiplication.
