ABSTRACT
Evaluations of task guidance systems often focus on evaluations of new technologies rather than comparing the nuances of interaction across the various systems. One common domain for task guidance systems is warehouse order picking. We present a method involving an easily reproducible ecologically motivated order picking environment for quantitative user studies designed to reveal differences in interactions. Using this environment, we perform a 12 participant within-subjects experiment demonstrating the advantages of a head-mounted display based picking chart over a traditional text-based pick list, a paper-based graphical pick chart, and a mobile pick-by-voice system. The test environment proved sufficiently sensitive, showing statistically significant results along several metrics with the head-mounted display system performing the best. We also provide a detailed analysis of the strategies adopted by our participants.

Comparing order picking assisted by head-up display versus pick-by-light with explicit pick confirmation
ISWC '15: Proceedings of the 2015 ACM International Symposium on Wearable ComputersManual order picking is an important part of distribution. Many techniques have been proposed to improve pick efficiency and accuracy. Previous studies compared pick-by-HUD (Head-Up Display) with pick-by-light but without the explicit pick confirmation ...
A comparison of order picking assisted by head-up display (HUD), cart-mounted display (CMD), light, and paper pick list
ISWC '14: Proceedings of the 2014 ACM International Symposium on Wearable ComputersWearable and contextually aware technologies have great applicability in task guidance systems. Order picking is the task of collecting items from inventory in a warehouse and sorting them for distribution; this process accounts for about 60% of the ...
Evaluation of graphical user-interfaces for order picking using head-mounted displays
ICMI '11: Proceedings of the 13th international conference on multimodal interfacesOrder picking is the process of collecting items from an assortment in inventory. It represents one of the main activities performed in warehouses and accounts for about 60% of the total operational costs of a warehouse. In previous work, we ...
