Urushi (Japanese lacquer) is a natural resin paint with electrical insulating capability. By using it as a base material and coating material for electronic circuits, it is possible to construct a circuit with an elegant appearance and feel. It is also possible to build a multilayered electronic circuit by using urushi as insulation layers. In this study, we investigate techniques to construct touch interfaces using a multilayered electronic circuit (urushi circuit). At first, we fabricated an urushi circuit with a touch electrode consisting of two layers. To improve its appearance, we fabricated urushi circuits in which all touch electrodes are arranged on the top layer and all wires are hidden in the bottom layer. Moreover, as an extension of the touch interface, we built a grid of touch electrodes that realizes two-dimensional touch sensing.

We present an exploration of e-textile/soft materials that can be used to capture fidget traces, while providing the touch sensations that fidgeters report seeking out in everyday fidget objects [3,4,5]. We created two soft-bodied "sampler" objects with a range of smart fidgeting affordances, which we describe in this paper, along with a general outline of the range of properties explored. This work extends exploration of a novel design space introduced in [4], toward the end goal of creating smart fidget objects that aid self-regulation. We include an overview of our design process, present some preliminary insights about materials that support this design space, and conclude with current and future directions for the work.

Cortical Visual Impairment in children is a severe issue caused by prenatal injury of the brain affecting timely development during childhood. Therapists work with affected children to foster general development, to improve their learning, and to train sensory skills. In order to support effective and playful practices in Early Intervention we designed The Cuebe and present a working prototype. It is a tangible device that can detect and project colors, allowing therapists to 'magnify' those colors and creating a vast variety of playful interactions for and with children suffering from low vision. The exploration of the design domain and the iterative development of The Cuebe were driven by a co-design approach involving four therapists and 12 affected children. We describe use-cases from the field, illustrate The Cuebe's potential in Early Intervention sessions and discuss further improvements and directions of future developments.

We introduce the term Digital Dresses as Dynamic Displays as an emergent field in the domains of Wearable Computing and Embodied Interactions. This recent approach consists of turning clothing into visual - and sometimes audiovisual - displays to enable novel forms of interaction between the wearer, the viewer, the tangible clothing and the embedded content. In this context, we present Enchanted Wearable, a new optimized low cost approach to create Digital Dresses as Dynamic Displays. Enchanted Wearable is a technologically embellished and augmented garment containing a portable rear dome projection system that transforms the clothing fabric into a blank canvas displaying audiovisual content. With this system, we create a new form of expression through clothing to reflect identity, personality, emotions and inner states of the wearer. In this paper we first present the growing field of Digital Dresses as Dynamic Displays, then we survey and analyse existing prior art in this field using a specific list of characteristics: display technology, wearability, interactivity, brightness, context. Finally we present the design and technology behind our new Enchanted Wearable system and explain how it brings new perspectives to the field.

The accurate recognition of guitarist performance is challenging compared with other instruments because a guitar player typically plays several notes at once and uses both hands in different ways. In this paper, we propose a sensor-based guitar that consists of two groups of sensors. One sensor is used to recognize the fingering positions of the fretting hand, and the other is used to detect the guitar strings that are played by the picking hand. We design an embedded system for accurate sensing and propose a data analysis mechanism to precisely figure out the played pitch and the duration of notes using the sensed data. We realize our scheme as a high-quality prototype that detects guitarist performance with accuracy sufficient for the transcribing of a performance. We also present real application examples such as a rhythm game for interactive lessons and a music sharing feature with user created musical scores.

Research in smart textiles and garments has mostly focused on integrating sensing technology. In order to make garments that are truly interactive it is also essential to develop technologies for actuating smart garments and textiles. This paper introduces ShapeTex, a thermal shape changing fabric that uses laminate thermal expansion to actuate textiles. We present the design process and rationale for ShapeTex; we explain the fabrication process we have developed for making ShapeTex accessible to fashion designers and interaction designers. Based on co-creation sessions with designers we discuss requirements derived from this material. Finally we present a number of concept prototypes created to explore and illustrate the potential applications of ShapeTex.

There is a widely-held belief in the TEI and games communities that using tangible props enhances the player performance and gaming experience. Building on prior research in gaming, we studied people playing a video game using a gestural interface without props, with an incomplete or a complete tangible prop. The interaction with the tangibles was judged to be more natural, led to higher flow experience and was preferred, but there were no differences regarding performance, enjoyment, autonomy, presence and mental effort. There was a tendency that especially the incomplete tangible prop was judged as less intuitive and people felt less competent in gameplay. In contrast to prior research, the results show that tangible interaction is not always more beneficial than gestural interaction and that, especially for incomplete tangibles, any beneficial effects may be domain-dependent.

Recent advances in technology and miniaturization allow the building of self-levitating tangible interfaces. This includes flying tangibles, which extend the mid-air interaction space from 2D to 3D. While a number of theoretical concepts about interaction with levitating tangibles were previously investigated by various researchers, a user-centered evaluation of the presented interaction modalities has attracted only minor attention from prior research. We present Flyables, a system adjusting flying tangibles in 3D space to enable interaction between users and levitating tangibles. Interaction concepts were evaluated in a user study(N=17), using quadcopters as operable levitating tangibles. Three different interaction modalities are evaluated to collect quantitative data and qualitative feedback. Our findings show preferred user interaction modalities using Flyables. We conclude our work with a discussion and future research within the domain of human-drone interaction.

My project involves the construction of a series of experimental wearable digital technologies as expressive wigs. These wigs are designed to explore the interactions of the wearers and the spectators as the wig moves in elaborate ways to highlight the realms of aesthetic value and sensory experience. The participants are provoked, they are engaged, they are compelled into a state of awareness and curiosity while the digital object constitutes novel experiences that coincide with anthropomorphic interactivity. Furthermore, the expressive value of a digital object is turned inwards as it becomes an extension of the self and a source of multi-sensory communication. Ultimately, the digital object seeks to open a social dialogue on the aesthetic purpose of technology by encouraging people to extend their imagination through bodily interaction. Here the digital object enables the wearers to create engaging narratives and provocative expressions.

Digital devices usually contain pre-programmed constraints and behaviours. These behaviours are programmed by the architect of these devices. Analogue devices, on the other hand, are bound by the properties of the components connected to them. Controlling these components and external physical properties will in-turn lead to controlling the output of these devices. Many devices are built to perceive physical phenomena and react to certain stimuli. The Screaming Sun is an analogue noise-making instrument that experiments with light as a stimulus. It is a solar-powered interactive artifact that is meant to be played with and explored. The instrument, much like a living being, thrives on light. The performer plays the instrument by actually influencing the physical properties of light that shines on the instrument, and not by pushing buttons or turning knobs.
