AR Gesture Interface Activation Using Two-Step Intent Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Augmented Reality (AR) and Virtual Reality (VR) devices prone to mistakenly triggering interactive interfaces due to direct gesture interactions.
Innovation Solution
A method and apparatus that triggers an interface identifier by a first gesture, followed by an interactive interface at a specific position via a second gesture, allowing for precise control and avoiding mistaken triggers.

Engineering Contradiction Analysis
1Ease of operation
If direct gesture interaction is used to trigger interactive interface, then ease of operation is improved, but reliability deteriorates due to mistaken triggering
Solution Approach 1:
The interaction process is segmented into multiple distinct stages: first displaying an interface identifier in response to a first gesture, then requiring a second gesture on that identifier to trigger the actual interface. This segmentation separates the attention-grabbing function from the activation function, reducing accidental triggers while maintaining ease of use.
Solution Approach 2:
The system performs a preliminary action by displaying the interface identifier before actually triggering the interactive interface. This intermediate step allows users to confirm they intend to activate the interface, preventing mistaken triggering while keeping the overall interaction flow smooth and intuitive.
2Reliability
If multiple gestures are required to trigger interactive interface, then reliability is improved by avoiding mistaken triggers, but device complexity increases
Solution Approach 1:
The interface identifier serves as an intermediary element between the first gesture and the final interface activation. It acts as a mediator that confirms user intent without adding significant complexity, as it is simply a visual indicator that bridges the two-step process.
Solution Approach 2:
The interface identifier serves multiple functions: it indicates the location where the interactive interface will appear, confirms that the system has detected the first gesture, and provides a target for the second gesture. This multi-functionality reduces the need for additional separate components.

AI summary
A method for gesture interaction is proposed. The method includes: obtaining a first reality scene image, and in response to a detection of a first gesture that matches a first predefined gesture in the first reality scene image, displaying, at a first position corresponding to the first gesture, an interface identifier; and obtaining at least one frame of reality scene images, and in response to a detection of a second gesture that matches a second predefined gesture in the at least one frame of reality scene images, displaying the interactive interface at the first position, an operation position of the second gesture corresponding to the first position where the interface identifier is located, the interactive interface comprising at least one functional control.
