Ninja Track is a belt-shaped object that consists of ABS parts hinged both longitudinally and transversely. When lying flat, Ninja Track is adequately flexible. When the user folds Ninja Track at the longitudinal hinges, it loses its flexibility and becomes a rigid stick. We created two types of electronic toys as examples of digital content that use Ninja Track. One is a gaming gadget, which can transform from a whip into a sword both virtually and physically. The other is a musical instrument, which produces sounds depending on its shape and user interaction.
