Shape of progress bar effect on subjective evaluation, duration perception and physiological reaction Int. J. Ind. Ergon. (IF 1.662) Pub Date : 2020-11-21 Ying Li, Chunyu Liu, Ming Ji, Xuqun You
Progress indicators act as a status indicator for the visual response process, which in turn has a significant impact on human-computer interaction. We often see ring type and bar type progress indicators in our daily life, but how does one choose the appropriately shaped design? This study uses two experiments to answer the above question, with the aim of maximizing the quality of the user experience

An investigation on major physical hazard exposures and health effects of forestry vehicle operators performing wood logging processes Int. J. Ind. Ergon. (IF 1.662) Pub Date : 2020-11-14 Marius-Daniel Iftime, Adela-Eliza Dumitrascu, Dorin-Ion Dumitrascu, Valentina D. Ciobanu
Forest vehicle operators are occupationally exposed to combined hazards such as noise, whole-body vibration(WBV), adverse microclimate, and carbon monoxide. Such combined exposures may not only increase the risk of accidents but they may also have some synergized effects on the developments of major occupational diseases of the workers, which have been among the major concerns of the occupational safety

Ergonomic risk factors in glass artware industries and prevalence of musculoskeletal disorder Int. J. Ind. Ergon. (IF 1.662) Pub Date : 2020-11-14 Bhawana Rathore, Ashok Kumar Pundir, Rauf Iqbal
Glass artware manufacturing activities are highly repetitive, labor-intensive, and demand prolonged standing during the working shift. This leads to the development of musculoskeletal disorders (MSDs) symptoms among the workers. However, there is a scarce of study on the prevalence of MSDs symptoms and their associated risk factors among the glass artware workers. To address this research gap, this
