(I have written several articles in MAKE: Japan.)

AwareHanger (Pervasive 2011 Poster) AwareHanger is a context-aware hanger which can detect laundry statsus automatically and inform users via multiple media (e.g.,sounds or Twitter).

LunchCommunicator (Pervasive 2011 Demo) LunchCommunicator is a lunchbox-type device, which supports communication between family members -the lunch-creator and the lunch-consumer- using automatic capturing/playing techniques during the preparation/consumption of the lunchbox.

DrawerFinder (IUI 2011Short Paper) DrawerFinder helps users find commodities stored in storage boxes with drawers on a shelf. When a user opens a box, a camera attached above the shelf detects a visual marker attached to the box and the system automatically takes a picture. Users can browse these pictures using a common web browser.

IODisk （UIST 2010 Demo) IODisk is a disk-type I/O interface that helps users browse various digital contents intuitively in their living environment. IODisk mainly consists of a force-feedback mechanism integrated in the rotation axis of a disk. Users can control the playing speed/direction contents (e.g., videos or picture slideshows) in proportion to the rotational speed/direction of the disk. We developed a prototype system and some applications.

LetterTwitter (Ubicomp 2010 Video/Poster) LetterTwitter is a smart mailbox that can automatically capture dropped snail mail (s-mail), classify pictures into several categories (e.g., letters or flyers), and upload categorized pictures to the Web.

MediAlarm (Pervasive 2010 Demo) MediAlarm is a novel alarm-clock interface which can wake people using a combination of various media, such as sound, lighting, vibrations, room temperature, and SNS (Social Networking Services). People are able to select various alarms based on their desired “wake-up level”– the urgency with which they want to be woken – using simple controls.

BoxFinder (Pervasive 2010 Demo) BoxFinder helps users find unclassified items stored in boxes using pictures and visual markers. By capturing pictures of the commodities stored in boxes with a visual marker using on-hand/fixed digital cameras, users can then browse these pictures using either an offsite Web browser or an onsite mobile computer.

EyeCatcher （Pervasive 2010 Full Paper) EyeCatcher is a novel interactive technique for digital camera, to help photographers capture a variety of natural looking facial expressions by keeping the eyes of subjects focused on the camera without the stress of photography.

ChameleonBall (TEI 2010 Demo) ChameleonBall is a novel ball-type input/output (I/O) device that allows users to interact with colors in the real world.

HomeOrgel (Ubicomp 2008 Demo) HomeOrgel is an auditory interface modeled on a music box, which can present home activities with natural sound. Users can hear the sounds of current and past activities with the BGM mechanism of the music box.

TagTansu (Pervasive 2008 Poster) TagTansu is a capture and anotation system for clothes to support creating a picture database of clothes. Using TagTansu, users can easily take pictures of clothes and add different tags to the pictures just by hanging clothes on different hooks.

WillCam（CHI 200７ Poster) WillCam is a novel digital camera which can capture various context information in addition to the photo itself.

PhantomParasol（Pervasive 2005 Poster) PhantomParasol is a parasol-type display which can show both ambient and detailed information with smooth transition.

MouseField（Ubicomp 2004 Full Paper) MouseField is a new simple and versatile input device, which enables users to control various information appliances easily without huge amount of cost.

ActiveBelt（Ubicomp 2004 Full Paper) ActiveBelt is a belt-type wearable tactile display that can transmit multiple directional information. ActiveBelt helps users reach their destinations without watching maps.

Dying Link（HCII 2003 Short Paper)> Dying Link is a new visualization technique that makes links to Web pages look aged according to how old the pages are. It visializes the link to an old page in a blurred text or a vague figure.

Using Ubi-Finger, a user can select a target device by pointing with her/his index finger, and then control it flexibly by performing natural gestures of fingers.
