Abstract

Warehouse picking is a traditional part of assembly and inventory control, and several commercial wearable computers address this market. However, head mounted displays (HMDs) are not yet used in these company's products. We present a 16 person user study that compares the efficiency and perceived workload of paper picking lists versus a HMD system aided by contextual cueing. With practice, users of the HMD system made significantly faster picks and made less mistakes related to missing or additional picked items overall.
