FluxPaper: Reinventing Paper with Dynamic Actuation Powered by Magnetic Flux

FluxPaper still imageFluxPaper is a new paper-based medium that enables physical movement and dynamic interaction between a high-power magnetized paper and a programmable magnetic field. FluxPaper has a very thin patterned magnetic layer (0.1 mm) pasted behind the paper. We describe the functions of magnetized paper; challenges through realization; and the interaction scenarios in several applications, such as self-alignment, self-construction, floating on the board, and quickly picking out a target card from a stack.

SenSkin: Adapting Skin as a Soft Interface

senskin-imageSenSkin is a sensing technology and input method that uses skin deformation estimated through a thin band-type device attached to the human body, the appearance of which seems socially acceptable in daily life. An input interface usually requires feedback. SenSkin provides tactile feedback that enables users to know which part of the skin they are touching in order to issue commands. The user, having found an acceptable area before beginning the input operation, can continue to input commands without receiving explicit feedback.

FlashTouch: Data Communication through Touchscreens

flashtouch-imageFlashTouch is a new technology that enables data communication between touchscreen-based mobile devices and digital peripheral devices. Touchscreen can be used as communication media using visible light and capacitive touch. It eliminates the complexity associated with data sharing among mobile users, which is currently achieved by online data sharing services or wireless connections for data sharing that need a pairing operation to establish connections between devices.

iRing: Intelligent Ring Using Infrared Reflection

iringiRing is an intelligent input ring device developed for measuring finger gestures and external input. iRing recognizes rotation, finger bending, and external force via an infrared (IR) reflection sensor that leverages skin characteristics such as reflectance and softness.

Pygmy: Ring-like Robot That Magnifies the Finger Expression

pygmyFinger has various patterns of expression by forming itself. Ring robotic device named Pygmy magnifies expression by animating, characterizing and anthropormophizing the human hand.

Multi-touch Steering Wheel for In-car Tertiary Applications using Infrared Sensors

wheelThis system can recognize hand gestures at any position on the steering wheel by utilizing 120 infrared (IR) sensors embedded in it. The sensors are lined up in an array surrounding the whole wheel. An Support Vector Machine (SVM) algorithm is used to learn and recognize the different gestures through the data obtained from the sensors. The gestures recognized are flick, click, tap, stroke and twist. Additionally, we implemented a navigation application and an audio application that utilizes the torus shape of the steering wheel.

Tangential Force Sensing System on Forearm

ah2013Since the forearm has a cylindrical shape, its surface deformation propagates to neighboring areas around a wrist and an elbow. The deformation can be used to estimate tangential force on the forearm. Our system does not require any equipment for the active side (i.e. fingers or a palm). Thus a user can touch the forearm in arbitrary ways. We show basic numerical simulation and experimental results which indicate that the proposed system can detect tangential force on the forearm. Also we show some possible applications that use the forearm as a human-computer interface device.

PINOKY: A Ring That Animates Your Plush Toys

pinokyPINOKY is a wireless ring-like device that can be externally attached to any plush toy as an accessory that animates the toy, such as by moving its limbs. A user is thus able to instantly convert any plush toy into a soft robot.
