Biomechanical analysis of accurately and carefully placing an aerospace avionics box in restricted space
Publication date: July 2019Source: International Journal of Industrial Ergonomics, Volume 72Author(s): Damon Burns Stambolian, Shihab Asfour, Arzu Onar-Thomas, Moataz EltoukhyAbstractThe design of a spacecraft has many trade-offs to reduce its mass, which typically result in reduced work space for the installation of Line Replaceable Units (LRU). One common LRU in aerospace vehicles is the avionics box found in the space shuttle. To prevent damage to cold plates, the installation of these boxes requires designing for accurate and careful placement; yet there are no standards to follow nor studies to consider for designers ...

An imperceptible barcode can reduce the muscle activity required to scan common consumer packaged goods
Publication date: July 2019Source: International Journal of Industrial Ergonomics, Volume 72Author(s): Kaitlin M. Gallagher, Molly Jensen, Marcus Payne, Raymond TowneAbstractWhile the Universal Product Code (UPC) has remained unchanged since its implementation in the 1970s, new technology and consumer package good layouts have started to change the UPC layout. The purpose of this study was to compare how upper extremity muscle activity was altered when scanning consumer packaged goods enhanced with an imperceptible barcode or a multi-sided UPC layout. Seventeen experienced cashiers participated in this study. Electromyogra...

A screening tool for occupations requiring a high level of attentional performance
Publication date: July 2019Source: International Journal of Industrial Ergonomics, Volume 72Author(s): Ying-Yin Huang, Marino Menozzi, Caroline FaveyAbstractVigilance tasks with a high level of attentional demand are becoming more frequent in daily work. High levels of attentional demand are required in critical systems, such as air traffic control, crowd monitoring, visual quality inspection, or sports.In a previous study, we introduced an ecologically valid test for screening visual attention in the general working population. The test requires participants to complete a visual search task at a moderate level of difficul...

Reliability of a new risk assessment method for visual ergonomics
ConclusionVERAM is a reliable instrument for assessing risks in visual work environments. However, the reliability might increase further by improving the quality of training for evaluators. Complementary evaluations of VERAM's sensitivity to changes in the visual environment are needed.Relevance to industryIt is advantageous to set up a work environment for maximal visual comfort to avoid negative effects on work postures and movements and thus prevent visual- and musculoskeletal symptoms. This method, VERAM, satisfies the need of a valid and reliable tool for determining risks associated with the visual work environment....

Visual scan patterns reflect to human-computer interactions on processing different types of messages in the flight deck
Publication date: July 2019Source: International Journal of Industrial Ergonomics, Volume 72Author(s): Wen-Chin Li, Jingyi Zhang, Tam Le Minh, Jiaqi Cao, Lei WangAbstractThe flight deck of commercial aircraft is sophisticated and searching for the necessary information at the right time is sometimes challenging. This research investigates pilot's visual parameters while interacted with two different designs of crew alerting system by eye tracking technology. There are 24 aviation professionals that participated in this experiment including commercial pilots, private pilots and avionic engineers. Compared with traditional d...
