1. Paper Generator

The Paper Generator is a new energy-harvesting technology that generates electrical energy from user interactions with paper-like materials. These energy harvesters are flexible, lightweight, and inexpensive. They utilize a user’s gestures such as tapping, touching, rubbing, and sliding to generate energy.

The harvested energy is used to actuate LEDs, e-paper displays, buzzers, and other devices to create interactive applications for books, postcards, posters, and other printed media.

2. PneUI

PneUI: Pneumatically Driven Soft Composite Material for Shape-Changing User Interfaces from Tangible Media Group on Vimeo.

Inspired by ocean organisms that morph and move bodies without rigid skeletons, PneUI (p’newee) is an enabling technology to build shape-changing interfaces through pneumatically actuated soft composite materials. The composite materials integrate the capabilities of both input sensing and active shape output. This is enabled by the composites’ multilayer structures with different mechanical or electrical properties. The shape-changing states are computationally controllable through pneumatics and predefined structure. The design space of PneUI is explored through four applications: height-changing tangible phicons, a shape-changing mobile device, a transformable tablet case, and a shape-shifting lamp.

3. Transmogrification

A transmogrifier is a novel interface that enables quick, on-the-fly graphic transformations. An image region can be specified by a shape and transformed into a destination shape with real-time visual feedback. Both origin and destination shapes can be circles, quadrilaterals, or arbitrary shapes defined through touch. Transmogrifiers are flexible, fast, and simple to create and invite use in casual InfoVis scenarios, opening the door to alternative ways of exploring and displaying existing visualizations (e.g., rectifying routes or rivers in maps), and enabling free-form prototyping of new visualizations (e.g., lenses).

4. Traxion

Traxion: a tactile interaction device with virtual force sensation from rkmtlab on Vimeo.

This research introduces a mechanism to induce a virtual force based on human illusory sensations. An asymmetric signal is applied to a tactile actuator such that the user feels the device is being pulled or pushed in a particular direction, although it is not supported by any mechanical connection to other objects or the ground. The proposed device is smaller and lighter than any previous force-feedback devices. This small form factor allows the device to be implemented in several interactive applications, such as a pedestrian navigation or an untethered input device with virtual force.
