Replay: a self-documenting construction kit

Abstract

Replay is a self-documenting construction kit for children to both share their designs with others and reflect on their own design process. Replay consists of a set of angular pieces that can sense their connection and orientation. A virtual model is rendered in real time as a design is constructed, and an on-screen playback interface allows users to view models from multiple perspectives and watch how a design was assembled. This paper describes the early development of Replay and describes potential directions for the documentation of physical designs.
