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.

An Augmented Reality (AR) guide system that does not spoil a space design is important for a museum. In this paper, we propose an AR guide system that uses an Light Emitting Diode (LED) as a marker. An LED marker does not spoil a space design and yields high recognition accuracy even from a long distance. For a user, an LED marker is intuitive and can provide the content in a highly enjoyable manner. We also discuss fusion of the low-cost LED marker recognition method and the accelerometer-gyroscope sensor. Our system can easily be used with unmodified examples of commercially available mobile devices. © 2013 The Institute of Electrical Engineers of Japan. Source

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. Source

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.

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. Source
