The system also provides a search module for identifying at least one matching item from the plurality of inventory items. The system provides a customer tracking module for identifying the physical location of each computing device on each multi-dimensional model. The system enables annotating portions of each multi-dimensional model into gender specific portions of each sales floor for determining the gender of the user of each computing device of forecasting the inventory management.
