Extended investigations of user-related issues in mobile industrial AR

Abstract

The potential of Augmented Reality (AR) to support industrial processes has been demonstrated in several studies. While there have been first investigations on user related issues in the long-duration use of mobile AR systems, to date the impact of theses systems on physiological and psychological aspects is not explored extensively. We conducted an extended study in which 19 participants worked 4 hours continuously in an order picking process with and without AR support. Results of the study comparing strain and work efficiency are presented and open issues are discussed. ©2010 IEEE

The Effect of Spatial Reference on Visual Attention and Workload during Viewpoint Guidance in Augmented Reality

“…To study workload issues on viewpoint guidance, it is useful to use a task sharing the same resources with the primary one. Thus, a visual secondary task causes a higher performance-related workload than the use of a primary visual and a secondary auditory task, as [17] has done. Given our focus on visual attention control, we need a suitable task to measure executive attention, such as a visual oddball task.…”

“…However, Kishishita et al [29] used a Sudoku puzzle for the secondary loading task but analyzed the effect of wide field displays on visual perception. Other work, comparing paper with AR guidance [17], applied a split attention task using visual and auditory stimuli to interfere picking tasks during pre-test and post-test phases, but did not report related details and could not show differences on secondary-task load. When selecting the secondary tasks it is necessary to match the task to the primary task, so that the user is adequately loaded for the assessment of a context-specific sensitivity [9].…”

“…Since mental stress causes sympathetic activation and parasympathetic degradation [10,28], it is suitable to evaluate mental workload. Analyzing the heart rate and its variability is not common in research on AR-related issues, although studies investigating the effect of AR on picking tasks [17,46,54] considered cardiac responses for workload assessment, but could not show differences between traditional paper-lists and AR guidance. Neither the classical research on viewpoint guidance nor those in AR estimated mental workload by physiological measures.…”

A Survey of Calibration Methods for Optical See-Through Head-Mounted Displays

“…In addition, objective stress measures could be employed. In contrast to evaluating effects of HMD usage on user comfort [20], there have been no evaluations on long term effects of HMD slippage in real-world scenarios. These investigations could help to understand the practical boundaries that automated calibration methods would need to account for.…”

A study on differences in human perception between a real and an AR scene viewed in an OST‐HMD

“…They analyzed HRV measures and found that there is no difference between the two tasks. Later, Grubert et al designed a new experiment based on Tümler's one. They extended the duration of the tasks, but, once again, there was no significant difference between the two tasks.…”
