Assessing Differences on Eye Fixations by Attention Levels in an Assembly Environment.

The purpose of this study is to see how eye movement can be used to determine how much attention a person is paying to a task in an assembly setting. The study uses the Dikablis Eye Tracking Glasses to analyze differences in length and number of eye fixations. Two groups of participants; the high and low attention level groups were compared to understand differences between workers who give full attention and those who do not. The participants who were assigned in the low attention level group had to memorize some given numbers throughout their assembly task while the high attention level group only had to complete the assembly task. According to our results, three of the six areas of interest locations had significantly different eye fixation lengths and one of the six locations had a significantly different number of eye fixations. The findings show that analyzing eye fixation lengths could be a way to measure a worker’s attention level during an assembly task.
