FluxPaper: Reinventing Paper with Dynamic Actuation Powered by Magnetic Flux

CHI 2015

FluxPaper 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.

SkinWatch: Skin Interaction for Smartwatch

AH 2015

We propose SkinWatch, a new interaction modality for wearable devices. SkinWatch provides gesture input by sensing deformation of the skin under a wearable wrist device, also known as a smart watch. A gesture command that is matched by learning data and two-dimensional linear input recognizes the gestures. The sensing part is small, thin, and stable, to accept accurate input via a user’s skin. We also implement an anti-error mechanism to prevent unexpected input when the user moves or rotates his or her forearm. The whole sensor costs less than $1.50 and the sensor layer does not exceed a height of more than 3 mm in this prototype. We demonstrate sample applications with a practical task; using two-finger skin gesture input.

SenSkin: Adapting Skin as a Soft Interface

UIST 2013

SenSkin 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

CHI 2013

FlashTouch 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

UIST 2012

iRing 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.

PINOKY: A Ring That Animates Your Plush Toys

CHI 2012

PINOKY 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.

Pygmy: Ring-like Robot That Magnifies the Finger Expression

APCHI 2012

Pygmy is an ring-like robot that magnifies finger expressions. It is based on the concept of hand anthropomorphism and it uses finger movements to create the anthropomorphic effect. Wearing the device is similar to having eyes and a mouth on the hand; the wearer's hand spontaneously expresses their emotions.

おしゃぶりセンサ (Pacifier sensor)

GUGEN 2014

「おしゃぶりセンサ」は、吸い方のパターンや強さを計測して赤ちゃんの状態をセンシングする目的で開発されたデバイスです。赤ちゃんの状態をセンシングする目的で設計され、センサ、基板、Bluetooth無線装置、バッテリーが内蔵されています。赤ちゃんの負担軽減のため、通常のおしゃぶりに比べて重量は2倍以内に抑えています。おしゃぶりの先端のゴムの中に距離センサを入れて、舌や口の動きを計測します。
