AR Gaze Selection for Offline Virtual Purchases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented and virtual reality systems face challenges in enabling rapid and efficient transactions, particularly for small-value purchases, without substantial system resource consumption and network access, especially during offline or time-sensitive conditions.
Innovation Solution
A method utilizing a head-mounted display (HMD) device that detects user interactions such as gaze, head motions, and gestures to select virtual features, generates a transaction management widget, and supports deferred payment obligations, allowing transactions without immediate account creation or network access, using cryptocurrency ledgers or electronic wallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional purchase interfaces are used in augmented reality, then users can make purchases, but the process requires substantial user interaction and system resources
Solution Approach 1:
The system automatically detects when a user is looking at a virtual item and initiates the purchase process without requiring manual activation. The purchase interface appears automatically based on gaze detection, and the system monitors user interaction patterns to confirm purchase intent, reducing the burden on users while maintaining security.
Solution Approach 2:
The system pre-configures purchase parameters and interfaces before the user actually wants to buy something. By detecting gaze direction and monitoring interaction patterns in advance, the system prepares the purchase interface and validates user intent before the actual transaction, enabling rapid purchase completion with minimal user input.
2Reliability
If network access is required for transactions, then payment processing is reliable, but offline or time-sensitive conditions prevent purchases
Solution Approach 1:
The system establishes and monitors user intent and purchase parameters in advance, before network connectivity is needed. By detecting gaze direction, monitoring interaction patterns, and pre-validating purchase intent, the system prepares all necessary transaction data locally, enabling rapid completion when network connectivity becomes available without time-sensitive delays.
3Adaptability or versatility
If multiple payment options are provided, then user flexibility is improved, but system complexity increases
Solution Approach 1:
The system implements a unified payment interface that can handle multiple payment methods (cryptocurrency, electronic wallet, credit card) through a single standardized protocol. The payment processing system abstracts the complexity of different payment methods, presenting a consistent user experience while maintaining the ability to process various payment types through centralized processing logic.

AI summary
Methods for an augmented-reality system for enabling rapid selection of a virtual feature with limited user interaction includes establishing a data connection between a head-mounted display device (“HMD”) and a network, and the HMD generating and displaying a virtual selectable feature based on detection of an item or characteristic appearing in a view of the real-world environment, as well as obtaining first information from a HMD sensor indicating a particular user interaction with the HMD, such as the user gazing at the feature for potential selection. The HMD then displays a countdown timer that operates over a predetermined time interval. If the HMD determines that the user interaction is continuous for that time interval; it transmits a request signal to a computer server offering content associated with the selected virtual feature; and displays virtual content, and/or executes a software program based on the received content from the computer server.
