Poupyrev, Ivan, Harrison, Chris and Sato, Munehiko (2012): Touché: touch and gesture sensing for the real world. In: Proceedings of the 2012 International Conference on Uniquitous Computing 2012. p. 536.

Touch proposes a novel Swept Frequency Capacitive Sensing technique that can not only detect a touch event, but also recognize complex configurations of the human hands and body. Such contextual information significantly enhances touch interaction in a broad range of applications, from conventional touchscreens to unique contexts and materials. For example, in our explorations we add touch and gesture sensitivity to the human body and liquids. We demonstrate the rich capabilities of Touch with five example setups from different application domains and conduct experimental studies that show gesture classification accuracies of 99% are achievable with our technology.

Harrison, Chris, Sato, Munehiko and Poupyrev, Ivan (2012): Capacitive fingerprinting: exploring user differentiation by sensing electrical properties of the human body. In: Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 537-544.

At present, touchscreens can differentiate multiple points of contact, but not who is touching the device. In this work, we consider how the electrical properties of humans and their attire can be used to support user differentiation on touchscreens. We propose a novel sensing approach based on Swept Frequency Capacitive Sensing, which measures the impedance of a user to the environment (i.e., ground) across a range of AC frequencies. Different people have different bone densities and muscle mass, wear different footwear, and so on. This, in turn, yields different impedance profiles, which allows for touch events, including multitouch gestures, to be attributed to a particular user. This has many interesting implications for interactive design. We describe and evaluate our sensing approach, demonstrating that the technique has considerable promise. We also discuss limitations, how these might be overcome, and next steps.

Sato, Munehiko, Suzuki, Yasuhiro, Nishizaka, Shinya, Torigoe, Yusuke, Izumihara, Atsushi, Hiyama, Atsushi, Nishimura, Kunihiro, Tanikawa, Tomohiro and Hirose, Michitaka (2010): Highly integratable large-scale displays for public spaces. In: Proceedings of the 2010 International Conference on Uniquitous Computing 2010. pp. 427-428.

The use of large visual displays in public space has become increasingly popular. However, it is still difficult to install new displays in already existing buildings because of the large and rigid hardware associated with such displays. In this paper, we describe a highly integratable, easily and quickly installable, and lightweight display system for use in existing public buildings. We describe the technical design and implementation of the display system and describe an application of the display for public audiences.

Narumi, Takuji, Sato, Munehiko, Tanikawa, Tomohiro and Hirose, Michitaka (2010): Evaluating cross-sensory perception of superimposing virtual color onto real drink: toward realization of pseudo-gustatory displays. In: Proceedings of the 2010 Augmented Human International Conference 2010. p. 18.

In this research, we aim to realize a gustatory display that enhances our experience of enjoying food. However, generating a sense of taste is very difficult because the human gustatory system is quite complicated and is not yet fully understood. This is so because gustatory sensation is based on chemical signals whereas visual and auditory sensations are based on physical signals. In addition, the brain perceives flavor by combining the senses of gustation, smell, sight, warmth, memory, etc. The aim of our research is to apply the complexity of the gustatory system in order to realize a pseudo-gustatory display that presents flavors by means of visual feedback. This paper reports on the prototype system of such a display that enables us to experience various tastes without changing their chemical composition through the superimposition of virtual color. The fundamental thrust of our experiment is to evaluate the influence of cross-sensory effects by superimposing virtual color onto actual drinks and recording the responses of subjects who drink them. On the basis of experimental results, we concluded that visual feedback sufficiently affects our perception of flavor to justify the construction of pseudo-gustatory displays.

Sato, Munehiko (2008): Particle display system: a real world display with physically distributable pixels. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3771-3776.

In this paper, the author designs and implements a new display system called Particle Display System, which can be installed on the non-planar surface of any objects. It consists of hundreds of full-color and wireless Light Emitting Diode (LED) nodes with a PC and video camera. The wireless capability makes the each node freely movable without distant limitation of the use of wire cables. By processing the images from the camera, the system calculates the positioning information of the each node and performs the timing control of the LED in the each node in real time. Therefore, the author is able to design a uniquely arranged pattern in full-color in the real world, by distributing and controlling the smart nodes. This paper describes the design and implementation of the prototype of Particle Display System.
