SilverCodes: Thin, Flexible, and Single-Line Connected Identifiers Inputted by Swiping with a Finger

Abstract

This study investigates SilverCodes, thin and flexible identifiers that serve to constitute an input interface. SilverCodes are thin and flexible barcode-shaped identifiers. User input is achieved by swiping an identifier with a finger. SilverCodes are made from two sheets of paper pasted with conductive ink. Identifiers can thus be conveniently printed using an ordinary ink-jet printer. Multiple SilverCodes can be connected by a single-line wire to an external module that recognizes the identifier swiped by the user. Furthermore, SilverCodes can be stacked and identifiers can be recognized to an average accuracy of 95.3%.
