TRANSACTION SESSION FOR WEARABLE PROCESSING DEVICE

A transaction session is established directly or indirectly between a wearable processing device and a cloud-based server of a store. During the session, items are recognized by placing the items in a field-of-view of a front-facing camera of the device. Item recognition does not require item barcode identification. A depth sensor associated with the camera creates a three-dimensional mapping of a given item. The mapping and image features are processed to uniquely identify the item even when the item is associated with a same category of items. Customer input during the session can be achieved through gestures (hand, eyes, head, fingers, etc.) and/or voice commands. The customer input is translated and mapped into transaction interface commands/options and processed during the session to select items, delete items, view a transaction receipt, identify a quantity of items, obtain item details for a given item, etc.
