I am interested in creating interfaces and technologies that seamlessly merge digital and physical in everyday objects, tools and environments.

The projects archived below describe some of the modest steps that I took in this direction. They cover work that I did at Disney Research, Sony Computer Science Labs in Tokyo, Advanced Telecommunicaiton Research Institute in Kyoto, University of Washington in Seattle and Hiroshima University.

Ishin-Den-Shin: Transmitting Sound via Touch.

Can we use the human body as medium for analogue sound transmission and playback? Ishin-Den-Shin project allows to transmit and playback recorded audio messages through the act of touching real world artifacts, which could be artificial objects or even a human ear [more details ...].

AIREAL: Tactile Feedback in Free Air.

How can we create a physical, tactile feeling for virtual objects floating in air? AIREAL uses computer-controlled air vortexes to enable users to feel virtual objects in free space as well receive dynamic tactile feedback on hands and body motion, all without requiring them to wear a physical device. The AIREAL free air tactie feedback generator is inexpensive, precise and provides effective tactile sensations at large distances [more details ...].

Printed Optics.

How will the interactive objects of tomorrow be manufactured? Printed Optics is a design and manufacturing approach where the form and interactive functions of an object are created simultaneously using optical 3D printing technology. With Printed Optics both sensing and display elements are printed within a physical model to create highly personalized interactive toys, devices, and objects [more details ...].

Botanicus Interacticus: Interactive Living Plants.

We envision a future where interactive devices are not manufactured but are growing, living organisms. Botanicus Interacticus is an exploration into the design of highly expressive interactive plants, both living and artificial. Based on Touché technology, it allows to enhace plants with gestures interaction, detection of touch and grasp location, proximity, and estimating the amount of touch contact. The instrumentation of living plants is simple, non-invasive: only a single wire is placed anywhere in the plant soil [more details ...].

REVEL: Programming Sense of Touch.

When the physical objects around us are infused with information and become interactive, how can they communicate with the user? REVEL overlays a layer of virtual tactile textures on everyday objects, allowing us to control what the user feels when they slide their fingers over them. Surfaces and objects such as walls, furniture, plastic or wooden objects, and even human skin can be augmented with artificial tactile sensations [more details ...].

Capacitive Fingerprinting.

Can objects recognize who is touching them? Capacitive Fingerprinting explores how the electrical properties of the human body can be used to differentiate users when touching screens or other touch-sensitive devices. Capacitive Fingerprinting enables development of highly personalized interfaces for collaborative applications, multi-user gaming, location-based entertainment and many others [more details ...].

Touché: Making Real World Touch Sensitive.

Touché is a new touch sensing technology that can not only detect a single touch, but simultaneously recognize complex configurations of the human hands and body. Instrumenting the world with Touché is easy: a single wire is sufficient to make objects and environments both touch and gesture sensitive. In our studies we added complex touch and gesture sensitivity not only to computing devices and everyday objects, such as a door knob, but also to the human body and liquids [more details ...].

SideBySide: Collaborative Mobile Projectors.

SideBySide lets people play together using handheld projectors anytime and anywhere. The interaction is immediate and simple: users project onto any surface and their projections become aware and responsive to other projections nearby. The applications of SideBySide can range from games, such as boxing with projected characters, to everyday tasks, e.g. exchanging personal contact information [more details ...].

Surround Haptics and Tactile Brush.

We developed a new tactile technology that uses low-resolution grids of vibrating actuators to create high-resolution, continuous moving tactile strokes on human skin. Our technology is based on modeling and controlling tactile illusions and it can be used to design novel compelling tactile experiences for computer games, rides and park attractions, devices for blind and interfaces for vehicle control [more details...].

MotionBeam: Interactive Mobile Projectors.

We explores the use of mobile projectors to interact and control projected characters in gaming and storytelling. Physical movement of the projector, much like a motion controller, is used to guide and interact with the character. This creates a unified interaction style where sensor input and projector output are tied together within a single device [more details...].

TeslaTouch: Touchscreen tactile display.

TeslaTouch is a new tactile feedback technology for touch screens that does not use any mechanical motion. Based on a principle of electrovibration, it provides wide range of tactile sensations to fingers sliding across a touch surface. It allows simulating feeling of textures, grids and materials, feel interaction between virtual objects, encode additional information into tactile channel, and add tactile feedback to interface objects [more details...].

12 Pixels: Exploring mobile creativity.

How can we draw on a mobile phone witouht touch scrren? What kind of pictures can a person draw?

12Pixels is an innovative interface, mobile phone application, and web service that allows people to draw and share pixel-based imagery using only the regular twelve keys of the mobile phone. 12Pixels does not require expensive touch screen interfaces: anyone with a regular mobile phone and internet connection, everywhere from Tokyo to Nairobi, can create pixel-based art and share it with the world [more details...].

12Pixels is a collaborative project with Karl D.D. Willis. Sony Style of Japan released 12Pixels as a free service for general public in 2009.

Recording sound with Special Moments.

Special Moments proposes a new category of casual sound recording devices designed as everyday objects that can be used effectively without pressing buttons or selecting items from a menu. Instead they rely on embodied and gestural interaction to seamlessly blend sound recording into everyday user activities [more details...].

Special Moment is a collaborative project with Haruo Oba and Takuo Ikeda both from Sony Corporation. It was presented at CHI 2008 conference and reported in a prototype issue of Axis magazine.

Lumen: A shape-changing display.

Lumen is a concept of an interactive display device that can dynamically change its own mechanical shape in order to communicate information to the users [more details...].

Lumen is a collaborative project with Tatsushi Nashida and Shigeaki Maruyama, both from Sony Corporation. It was demonstrated at SIGGRAPH 2004 and ARS Electronica Festival 2005; it was also reported in the annual prototype issue of the Axis magazine.

Tactile user interfaces.

Tactile user interfaces allow people to perceive information through touch, leading to easier, more natural and enjoyable interaction.

My work on tactile user interfaces covers a range of projects, including the development of TouchEngine™ tactile feedback platform, designing tactile interfaces for pen interaction and small touch screens [more details ...].

Tactile interfaces research is a collaboration with Shigeaki Maruyama, Sony Corporation. It has been extensively published, reported in public media and released on on the market in a number of Sony products; which were the first consumer electronic products in the world that provided tactile feedback on touch screens.

Gummi: A bendable computer.

Gummi is an interface concept based on bending a flexible handheld computing device. We propose a concept of bendable computer, explore physical interactio techniques and screen interfaces for such devices [more details...]

Gummi was developed and investigated together with Carsten Schwesig and Ejiro Mori both Sony Corporation. Gummi design was presented at a number of conferences, demonstrated at the Wired NextFest festival and broadly covered in a variety of media.
