In this study, we investigated the difference of luxuriousness between real model house and web-based model house. Living room as the most important residential space was targeted as an evaluation object. 6 living rooms and 9 elements contained in each living room were evaluated in terms of luxuriousness. Through independent samples t-test, we could examine that there were statistically significant...
Since the comfort feeling and satisfaction of a toilet seat is important for the defecation, we investigated the design parameters and affective attributes for toilet seats, and developed the affective model that explains the level of customer satisfaction. To achieve, objective measurements of design parameters and total 19 number of relevant affective attributes including appropriateness of each...
This study investigates the difference in tactile sensory response when touching leathers under tactile-only and visuo-tactile environment. Total of 7 tactile variables for leathers were selected and utilized to investigate whether they derive significantly different tactile response by existence of visual interaction. As a result, affective variables of ‘rugged’, ‘elastic’, and ‘thick’ showed significant...
This study aims to identify and categorize the characteristics of user-generated content to obtain a profound understanding on the user data, and actively utilize the data in extracting user values. Based on literature review, characteristics of online reviews and photos on Social Network Services (SNS) were investigated to evaluate five categories for online reviews (interactive, imprecise, cultural,...
This study aims to extract the most relevant set consisted of affective variables to the level of user satisfaction on engine sounds using classification algorithm. The affective variables for engine sounds were defined by three axes, and two classification algorithms were used to determine the prediction accuracy for those affective axes. The study was consisted of three phases: 1) extracting sets...
Psychosocial stress is a common phenomenon in a working world. There are indications that psychosocial stress will increase muscle activity and eventually contribute to musculoskeletal disorders problem. The aim of this review is to identify the effect of psychosocial stress during computer work towards trapezius muscle activity.

Three terms, ‘visual search’, ‘eye movement’ and ‘eye track’, were selected as the central keywords characterizing the research field. Seven sub-categories of research keywords were selected and analyzed in content...
Summary. The findings of several studies suggest that liver stiffness values can be affected by the degree of intrahepatic congestion respiration influence intrahepatic blood volume and may affect liver stiffness. We evaluated the influence of respiration on liver stiffness. Transient elastography (TE) was performed at the end of inspiration and at the end of expiration in patients with chronic liver...
As the usability of mobile services has become a critical factor of success in market, needs for established usability evaluation methodologies and realistic practices that ensure capturing usability in evaluation are increasing. From a point of user-centered design perspective, customer perceived value (CPV) has recently gained much attention from usability experts and user interface (UI) practitioners...
A systematic modeling approach to describing, prescribing, and predicting usability of a product has been presented. Given the evaluation results of the usability dimension (UD) and the measurement of the product’s design variables, referred to as the human interface elements (HIEs), the approach enables one to systematically assess the relationship between the UD and HIEs. The assessed relationship...
