back to top  Cubes

Cubes is a collection of 20 objects, each combining an input and an output. Shaking the Dizzy Cube makes it totter around; rotating the Homesick Cube makes it turn back to face our lab. The Knock Cube returns your knock. By fixing the form of these interactive objects into the simplest shape—a cube—we can explore affordances and behaviors in a lab-like environment. Our cubes are transparent, showing the logic and beauty of their insides: electronic components and structure. The project celebrates the potential of simple tangible interactions, and the power of multiples, for engagement and pleasure.

Originally commissioned by the Design Museum Holon with generous funding from the Porter Foundation.

back to top  Constructable

Constructable is an interactive drafting table based on a laser cutter that produces precise physical output in every editing step. Users interact by drafting directly on the workpiece using hand-held laser pointers. The system tracks the laser dot, beautifies its path, and implements its effect by cutting the workpiece using a fast, high-powered laser cutter. Constructable achieves precision through tool-specific constraints, user-defined sketchlines, and using the laser cutter itself, rather than a screen or projection, for all visual feedback.

back to top  exTouch

The exTouch is an embodied, spatially aware interface system that allows users to manipulate actuated objects in space using augmented reality. The system extends users' touchscreen interactions into the real world by enabling spatial control over an actuated object. When users touch a device shown in live video on the screen, they can change its position and orientation through multi-touch gestures or by physically moving the screen in relation to the controlled object. We demonstrated that the system can be used for applications such as an omnidirectional vehicle, a drone, and moving furniture in a reconfigurable room.

back to top  Ninja Track

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.
