An inventory management system is described. The inventory management system may be configured to determine a head or eye level of an operator interacting with a storage structure. As part of this process, visual image data, thermal image data, or LiDAR data can be obtained and the eyes or head of the operator identified in the obtained data, or the operator may wear a device usable to determine head or eye position. The determined head or eye level can be correlated with a vertical position on a display, and inventory information can be displayed to the operator at the determined level.
