Abstract

Extant approaches to algorithm visualization (AV) construction range from low-level programming to mouse-clicking through a WIMP - Window, Icon, Menu, Pointing Device - interface. These approaches, while varying in degrees of ease of use, strike us as somewhat wanting in naturalness, if not downright restrictive. Based on observations of an on-going study, we argue that (1) without any coding or button clicking, students should be able to draw objects and control their movement with a pointing device or just their hands; (2) recording of students’ spoken explanation during the construction process should be supported by the AV system. By integrating hand movement and voice, two basic human affordances, into a new focus of the algorithm visualization construction approach, our work-in-progress aims to replicate the kind of low-tech, pen-and-paper AV construction experience and translates it into a computer-based AV system.
