Wearable Camera Gesture Search for Quiet XR Querying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR devices lack an efficient method for users to naturally generate queries associated with objects in their view without verbal commands or button presses, disrupting others in proximity.
Innovation Solution
A wearable device equipped with cameras, including RGB and depth sensors, identifies user gestures to generate queries based on images and voice inputs, communicating with a search engine to provide responses without requiring manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If users provide verbal commands to initiate searches, then search functionality is achieved, but it disturbs others in proximity
Solution Approach 1:
The patent replaces voice-based acoustic input with optical gesture-based input. The wearable device captures images of hand gestures using onboard cameras and uses computer vision to recognize gesture patterns, thereby substituting the acoustic field with the optical field for command input, eliminating verbal disturbance to others.
Solution Approach 2:
The patent introduces an intermediary gesture recognition system between the user and the search function. Instead of direct voice-to-search or manual button-to-search interaction, the user performs a gesture that is captured by the camera, processed through gesture recognition algorithms, and then triggers the search, providing a non-intrusive intermediary mechanism.
2Ease of operation
If users press buttons to initiate searches, then search functionality is achieved, but it requires manual input that may be cumbersome
Solution Approach 1:
The patent replaces mechanical button pressing with optical gesture recognition. The camera-based system captures hand movements and translates them into search commands, eliminating the need for physical button interaction and reducing the time and effort required to initiate searches.
Solution Approach 2:
The system enables self-service operation where the user's natural hand gesture automatically triggers the search function without requiring additional steps. The gesture itself serves as the command, and the system autonomously processes the gesture recognition and initiates the search, making the interaction intuitive and efficient.
3Ease of operation
If the wearable device processes images and gestures to generate queries, then natural search initiation is achieved, but device complexity increases
Solution Approach 1:
The wearable device leverages its existing camera hardware, originally designed for general imaging purposes in XR applications, and repurposes it for gesture recognition and query generation. This multi-functional use of the camera system reduces the need for dedicated specialized components, thereby managing device complexity while enabling natural gesture-based search initiation.

AI summary
According to at least one implementation, a method includes capturing an image and determining the image includes a gesture. The method further includes, in response to determining the image includes the gesture, generating a query from at least the image and the gesture and providing the query to a search engine. The method also provides receiving a response to the query and outputting the response.
