Ninja Track is a belt shaped object which possesses the capacity to alter its flexibility and hence strength. It consists at its modular level - a composition of two parts - the vertical hinges and horizontal hinges. When flat, Ninja Track is fluid and wavy. When the user folds it at the horizontal hinges, Ninja track becomes a rigid stick. Both the parts are made of ABS.

 

Using Ninja Track, we had created two applications. One is a physical game interface which can transform a whip into a sword virtually and physically.In the normal state, the user can use it as a whip when she/he swings it. When the switch is turned on, Ninja Track is automatically folded by the servo motor and the user can use it as a sword. Corresponding to the physical manipulations, Ninja Track alters its form giving the user tangible feedback and a more immersive experience.
