“…Concept five has a magnetic clasp which easier to use than the metallic 'S' of product concept one. Scholars suggest that the functionality of a product contributes to its usability (Chihara & Seo, 2014;Chowdhury et al, 2014;Jordan, 2000;Rubin & Chisnell, 2008). In addition, the apparent usability is generally perceived from novelty in product appearance and influences product appraisal (Mugge & Schoormans, 2012a;Mugge & Schoormans, 2012b).…”

Over the last two decades scholars have studied the relationship between product usability and consumer purchase intentions. It has been established that perceived usability is valuable for predicting intentions to purchase water bottles, kitchen appliances, smart devices, etc., but there has been little research on the role of usability in jewelry purchase decisions. Product aesthetics is also an important factor in consumers’ purchasing decisions; aesthetics creates attraction, evokes emotions and satisfaction in shoppers. This article aims to investigate the role of aesthetics and usability in jewelry purchasing decisions in India. A survey of 194 potential jewelry customers was undertaken, with respondents asked for their opinions on six product concepts for handmade glass pendants. Our results show that aesthetics, usability and willingness to purchase handmade glass pendants are strongly and significantly related to each other. When correlation and multiple regression analysis were performed on the survey data, it was found that both usability and aesthetics positively influence purchase intention. This study finds that aesthetics and apparent usability are both valuable predictors for purchase intention of glass pendants. Keywords: Aesthetics, Craft, Design, Apparent usability, Craft cluster

“…The scores of Physical Component Summary (PCS) and Mental Component Summary (MCS) were calculated according to the questionnaire results, then the standardized values of physiology and psychology could be obtained (Ware et al 1996;Gandek et al 1998). In the article of Chihara et al (Chihara and Seo 2014), the subjective satisfaction score of STS movement was divided into seven grades: 1-Very difficult, 2-Difficult, 3-Slightly difficult, 4-Indifferent, 5-Slightly easy, 6-Easy, 7-Very easy, which were determined by the subjective score of subjects. Jeyasurya et al (Jeyasurya et al 2013) provided a post-experiment questionnaire for all subjects, which referenced the 4-point Likert scale.…”

Sit-to-stand (STS) movement is a very common task for the elderly and the patients with lower limb dysfunction in daily life. We hope to summarize the methods of STS experiment and the factors affecting STS, and provide a reference for future STS experimental researches. We selected the relevant STS experimental studies, analyzed and compared the methods and results of these studies, and the suggestions for future research were made. In the exploration of STS movement experiment, human biomechanical data, kinematic data, kinetic data, time and subjective evaluation of subjects are all important indicators reflecting STS performance. External factors, individual factors of subjects and STS strategies also have a significant impact on the movement performance of STS. Simulation of human body can eliminate the influence of subjective factors on the movement of human body, and set anthropometry parameters more conveniently. We found that the influences of folding arms, hand support and knee support modes on STS need to be explored deeply. The appropriate weight reduce ratio for rehabilitation training system need to further study. We need to continue to explore new technologies to find the methods to create a human biomechanical model with higher simulation degree, improving the accuracy of the simulation.

“…However, the selection guide of the methods has not been proposed in ergonomic design field. Recent studies using these methods in the ergonomic design include the parameter determination for the ergonomic product to optimize the EMG of multiple muscles (Jeang et al , 2018; Chihara and Seo, 2014) and the multi-optimization of the characteristics related to the comfortable posture in factory work (Ma et al , 2009) and driving (Yang et al , 2009). However, there is no description about the reason of selecting these methods.…”

Purpose The purpose of this paper is to propose the selection guide of the multi-objective optimization methods for the ergonomic design. The proposed guide enables designers to select an appropriate method for optimizing the human characteristics composed of the engineering characteristics (e.g. users’ height, weight and muscular strength) and the physiological characteristics (e.g. brain wave, pulse-beat and myoelectric signal) in the trade-off relationships. Design/methodology/approach This paper focuses on the types of the relationships between engineering or physiological characteristics and their psychological characteristics (e.g. comfort and usability). Using these relationships and the characteristics of the multi-objective optimization methods, this paper classified them and constructed a flow chart for selecting them. Findings This paper applied the proposed selection guide to a geometric design of a comfortable seat and confirmed its applicability. The selected multi-objective optimization method optimized the contact area of seat back (engineering characteristic associated with the comfortable fit of the seat backrest) and the blood flow volume (physiological characteristic associated with the numbness in the lower limb) on the basis of each design intent such as a deep-vein thrombosis after long flight. Originality/value Because of the lack of the selection guide of the multi-objective optimization methods, an inappropriate method is often applied in industry. This paper proposed the selection guide applied in the ergonomic design having a lot of the multi-objective optimization problem.
