Information related to reliable values of discomfort thresholds can help to improve the designs of various products. This study aimed to investigate the measurement reliabilities associated with pressure thresholds, while determining the effects of stimulus characteristics (stimulus area, indentation speed) of the human foot. An indentation apparatus was(More)
Orthotics and other types of shoe inserts are primarily designed to reduce injury and improve comfort. The interaction between the plantar surface of the foot and the load-bearing surface contributes to foot and surface deformations and hence to perceived comfort, discomfort or pain. The plantar shapes of 16 participants' feet were captured when standing on(More)
There has been a growing trend among shoe manufacturers to introduce customized shoes to satisfy varying customer style, fit, and comfort needs, thus to increase the product's added value. This study presents a computer-aided design (CAD) system for designing a customized shoe last based on the chosen shoe style and customer's foot features. The CAD system(More)
The application of foot anthropometry to design good-fitting footwear has been difficult due to the lack of generalised models. This study seeks to model foot dimensions so that the characteristic shapes of feet, especially in the midfoot region, can be understood. Fifty Hong Kong Chinese adults (26 males and 24 females) participated in this study. Their(More)
The psychophysical relationship between the magnitude of pressure on thirteen test locations of twenty healthy subjects' feet with four probe areas at three indentation speeds and the corresponding perceived sensations were analyzed. The dependency of pressure pain thresholds (PPT) on area, A, and speed, v, can be mathematically modeled in the form, PPT(i)(More)
The mechanical properties of human foot tissue in vivo as well as discomfort and pain thresholds are important for various applications. In this study, an apparatus for measuring the discomfort and pain thresholds and the mechanical properties of human tissues is presented. The apparatus employs a stepper motor that controls the indentation speed, as well(More)
Customized shoes are desired in shoe industries nowadays to satisfy customer needs on style, fit and comfort. This paper proposes a CAD system for designing the customized shoe last based on the customer preferred shoe style and his/her foot features. Eighteen important foot features are firstly extracted from the laser-scanned foot data. The features are(More)
The need for sustainable development has been widely recognized and sustainable development has become a hot topic of various disciplines even though the role of ergonomics in it is seldom reported or considered. This study conducts a systematic survey of research publications in the fields of ergonomics and sustainable development over the past two decades(More)
With consideration of the decentralization of wheat fertilization management and status in quo in Henan province, the paper mainly designed county wheat decision-making System of survey and directions for soil Based on GIS. By collecting 3773 records of survey and directions for soil in 976 vilages, Hua county, protracting all kinds of vectorgraphs about(More)
