AR Virtual Item Trade Box for Reliable Ownership Transfer

The patent introduces a trade box as an intermediary interface between the virtual item and the receiving user. The trade box serves as a mediation zone where the virtual item must be placed to initiate transfer, and where the receiving user must reach to accept it. This intermediary mechanism resolves the contradiction by providing clear, unambiguous transfer intent recognition while maintaining simple handover gestures, as the trade box visually and functionally mediates the transfer process between giver and receiver.

The trade box mechanism enables self-service verification where the system automatically detects when the virtual item is placed in the trade box and when the receiving user reaches for it. The transfer intent is recognized through the users' natural actions of placing and reaching, without requiring complex manual verification processes. This self-service approach maintains reliability by automatically detecting clear intent signals while preserving ease of operation.

The patent applies local quality by creating a localized trade box around the receiving user that is visually distinct and spatially defined. This trade box serves as a local indicator that clearly identifies which user is the current transfer target, even when multiple users are present in the AR image. The receiving user within the trade box is highlighted through this localized visual cue, resolving the difficulty of detecting the transfer target while maintaining adaptability to multi-user social interactions.
