Protopiper is a computer-aided handheld fabrication device that allows users to sketch room-sized objects at actual scale. The key idea behind Protopiper is its main building material: It uses adhesive tape formed into tubes rather than extruded plastic or photopolymer lines. Since the resulting tubes are hollow, they offer excellent strength-to-weight ratio and thus scale well to large structures. By allowing users to sketch and prototype room-sized objects at actual scale, users can verify their designs during prototyping. For example, they can make sure that objects fit with the room or with their bodies.

BitDrones allows users to explore virtual 3D information by interacting with physical self-levitating building blocks. It is a first step toward interactive programmable matter—materials capable of changing their 3D shape in a programmable fashion—via swarms of nano quadcopters. Researchers at the Human Media Lab created three types of BitDrones: PixelDrones are equipped with one LED and a small dot-matrix display. ShapeDrones have a lightweight mesh on a 3D-printed geometric frame and serve as building blocks for complex 3D models. And DisplayDrones lift a curved flexible high-resolution touchscreen and a forward-facing video camera.

When using a conventional stereo microscope, users inevitably move their head away from the microscope to retrieve information. This increases the risk of losing focus and becoming fatigued during, for example, microsurgeries. Scope+, a stereoscopic video see-through augmented reality microscope, was created to solve these problems and to improve users' microscopic stereo vision. With a specially designed interactive guidance system, Scope+ provides an intuitive user experience with no special training process needed before using it.

As interactions with handheld devices and everyday objects become increasingly common, a more seamless and effortless identification and personalization technique will be essential for an uninterrupted user experience. Zensei is a versatile technique for effortlessly identifying and personalizing objects using bioimpedance sensing through an array of electrodes. Bioimpedance information allows us to identify the physiological and behavioral aspects that are unique to a user and customize or personalize an experience for them. We created a Zensei-powered interaction prototype to showcase its capabilities and to explore various interaction scenarios.
