Evaluation Of Fitts’ Throughput As A Possible Performance Measure For Manual Assembly Tasks, Pradyumna Bettagere Jagadish
Evaluation Of Fitts’ Throughput As A Possible Performance Measure For Manual Assembly Tasks, Pradyumna Bettagere Jagadish
Graduate Theses, Dissertations, and Problem Reports
Assembly lines are the backbone of the manufacturing sector. Workers at the assembly lines are expected to perform fast pace hand-arm exertions with precision and accuracy. To protect the workers from injuries, OSHA mandates the use of personal protective equipment (PPE) including gloves. Certain assembly operations require the use of special gloves. Some of these gloves can inhibit hand performance, further increasing the task difficulty. The Index of Difficulty (ID) is a metric measured in ‘bits’ quantifies task difficulty through the quotient of target width and target motion, i.e., distance travelled. The time required to complete the target motion is …
Evaluation Of Object Attributes To Study Speed-Accuracy Trade-Off Of Gloves Using Iso 9241-411 Standard, Isha Gaut
Graduate Theses, Dissertations, and Problem Reports
Selection of appropriate gloves plays an important role in the overall comfort and productivity of workers. Currently, there are no standards and/or guidelines available to systematically evaluate the glove performance based on speed-accuracy trade-off. The ISO 9241-411 standard which is based on Fitts’ Law has been extensively used in the literature to measure speed-accuracy trade-off in terms of throughput in the virtual environments. This study was aimed at developing guidelines for implementing ISO 9241-411 standard in the physical environment so that it can be used to estimate (and compare) throughputs of safety gloves. Specifically, the various physical attributes of objects …
