Breathing clothes are media artworks formed as an application of the hairlytop interface. The hairlytop interface is an assembly of fine, soft and deformable actuators. Each actuator is composed of a shape memory alloy (SMA) and drive circuits. Various types of sensors can be connected to the driving circuits. The actuators can then deform in reaction to surrounding stimuli, including light, sound, and human activity. The high flexibility of this configuration and its unique motion enables us to compose various interface types, such as furry decorated interfaces and new deformable textiles. In this paper, we describe in detail several types of clothes composed of this unique fabric combined with the hairlytop interface. The clothes act based on the wearer's breathing action, which acts as an indicator of the emotional state of the wearer. Copyright © 2014 ACM.

A pair of musical instruments named "Cosmical Seeds" suitable for weightlessness, was selected by the Japan Aerospace Exploration Agency (JAXA) to represent the theme of Cultural and Artistic Utilization of the International Space Station (ISS). The instruments were successfully launched on October 31, 2011; and NASA astronaut Daniel C. Burbank, Expedition 30 commander, operated and played the instruments on the ISS on February 10, 2012. The two pieces of music performed were a collaboration between an astronaut and ambient music specialists Akira Takahashi and Jaakko Saari. This paper will present: Motivation which led to the creation of the musical instruments The concept of the project The results of parabolic flight testing The results of the mission at the ISS Future possibilities The astronaut played the instruments along with music repeatedly for 15 minutes and improved his skills beyond what was outlined in the procedure manual. Taking movies and audio recordings was very successful, and the video will be shown at this session. Copyright © (2012) by the International Astronautical Federation.

Background: The Levels of Emotional Awareness Scale (LEAS) was developed to assess five levels of emotional awareness: bodily sensations, action tendencies, single emotions, blends of emotion, and combinations of blends. It is a paper and pencil performance questionnaire that presents 20 emotion-evoking scenes. We developed a Japanese version of the LEAS (LEAS-J), and its reliability and validity were examined.Methods: The LEAS-J level was independently assessed by two researchers who scored each response according to the LEAS scoring manual. High inter-rater reliability and internal consistency were obtained for the LEAS-J. Measures were socioeconomic status, LEAS-J, Toronto Alexithymia Scale-20 (TAS-20), Interpersonal Reactivity Index (IRI), and NEO Five-Factor Inventory (NEO-FFI). TAS-20, IRI and NEO-FFI were the measures used to explore the construct validity of LEAS-J, as it was predicted that higher scores on the LEAS-J would be related to fewer alexithymic features, greater empathetic ability, and a greater sense of cooperation with others. Questionnaires were completed by 344 university students.Results: The criterion-referenced validity was determined: a significant negative relationship was found with the externally-oriented thinking scores of TAS-20, and positive relationships were found with fantasy, perspective taking, and empathic concern on IRI and with extraversion, openness to experience, and agreeableness on NEO-FFI.Conclusions: Consistent with our expectations, the findings provide evidence that the LEAS-J has good reliability and validity. In addition, women had significantly higher scores than men on LEAS-J, showing that the gender difference identified in the original LEAS was cross-culturally consistent. © 2011 Igarashi et al; licensee BioMed Central Ltd.

Organic EL (OLED) has been attracting attention as a next-generation lighting fixture that can achieve high energy efficiency. One of the advantages of OLED is that there is a lot of flexibility in terms of choosing which organic materials to use, which in turm creates various spectral distributions of light. For this purpose, it is important to evaluate the performances of color perception under OLEDs. In this research, we measured the color discrimination performance under a prototype OLED light and compared the results with those derived under fluorescent light and under a commercially available LED lamp. Some observers had more difficulty discriminating color under OLED compared with under D65 fluorescent light. Although the spectral distributions of the light sources were different, the performances did not indicate any statistically significant hue dependences.

A simple correspondence between S-cone response and the sensation of blueness has long been questioned. We measured color appearance using a series of S-cone isolating stimuli and a paired comparison paradigm to identify a direct correspondence between S-cone response and perceived hue strength. The results revealed a non-monotonic reversal in perceived blueness at the unique-blue line: The S-cone increment initially increased blueness, but as S-cone excitation grew past the pure-blue line, blueness decreased and redness increased. It is difficult to account for this pattern of results by supposing that the sensation of blueness is mediated by a conventional linear channel that extracts (S+M)/L: If the ratio L:M is held constant, the output of such a channel should always increase with increasing S, and so inhibition from a second channel would be needed to account for our result. We also consider another category of explanation: The appearance of a given chromaticity may depend on its position relative to the fundamental axis of daylight locus, which serves as an internalized reference. In an account of the latter kind, there is a systematic mapping between chromaticities and sensations, but there does not need to be a distinct neural signal that represents "blueness." © 2014 Wiley Periodicals, Inc.

A practical application of Augmented Reality (AR) is see-through vision, a technique that enables a user to observe a virtual object located behind a real object by superimposing the virtually visualized inner object onto the real object surface. This technique is considered to be effective in several areas, including medical [Bichlmeier et al. 2007] [Lerotic et al. 2007] [Nicolau et al. 2011] [Sielhorst, et al. 2006] and industrial visualizations [Schall et al. 2009] [Zollmann et al. 2010]. In these applications, one challenge is determining how to cause a virtual object to appear behind a real object surface.

This study aims to clarify color rendering properties for two-color combinations when the spectral power distributions of light sources including LED lamps and illuminance change and also aims to calculate the color rendering values while taking illuminance into consideration. Subjects subjectively evaluated the feelings of the two-color combinations of the test side by comparing them with the feelings of those of the reference side by using the Semantic Differential method. In the results, affective evaluation values decreased for all test light sources when illuminance decreased. However, for the red and green combination samples, affective feelings under 10 lx of the LED lamp (LED-RGB) of the combination of red-green-blue LED are almost the same as those under 700 lx of the other light sources. Also, we tried to calculate the color rendering values while taking illuminance into consideration. There was no correlation between affective evaluation values and the color rendering values at any illuminance level. The results suggested that the current CIE-Ra, CIECAM02- Ra, and CIECAM02UCS- Ra are not be sufficient when color rendering properties are evaluated at low illuminace.

This study examined the relationships among illuminance level, light source spectral distribution and observation sample colors by subjectively evaluating color samples under various illuminations. It also clarified the evaluation structure when impression of color samples under various illuminations were sujectively observed. Four types of lamps (Ra19-Ra96), two illumination levels (700 lx, 10 lx), and three types of samples (two-color ones, multi-color arrays, pictures) were used. The results were found to depend on whether the sample contained red. Factor analysis with "color quality" and "preference" as factors revealed that subjective brightness and vividness of the red were important in forming a subjective impression of the samples.

Museum lighting environments are carefully controlled so as not to cause any damage or deterioration to artwork. However, no method currently exists for calculating the change in color rendering properties when illuminance is changed. The purposes of this study were to clarify color rendering properties at low illuminance and to develop a new method for calculating color rendering values while taking illuminance in to account. The results showed that subjective color feelings of color samples were influenced by illuminance as well as by hue in the samples, especially by red. We defined"color quality indices"called Rx and Rxi to evaluate the new color rendering properties expressing illuminance effects and hue effects. The new indices Rx and Rxi were found to correlate significantly with the subjective results.
