Camera-Based Gesture Interaction via Hotspot Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera-based systems face challenges in creating interactive content due to limited adoption and the inefficiency of recreating existing content for presentation, as they require learning new markup languages with limited utility.
Innovation Solution
A method is introduced where electronic documents are enhanced with hotspot attributes that allow users to interact using predefined physical gestures captured by a camera system, enabling interaction with the document without the need for new markup languages, by injecting hotspot attributes into document elements, allowing users to perform actions on the displayed document through gesture recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new markup languages are developed for camera-based systems, then camera-based interaction functionality is improved, but system complexity and learning curve increase
Solution Approach 1:
The patent applies universality by enabling standard web markup languages (HTML, XML, etc.) to serve dual purposes: traditional display purposes and camera-based interaction purposes. The hotspot attributes injected into standard document elements allow existing web content to be enhanced with camera-based gesture recognition capabilities without requiring separate markup languages, thus making the system universal across different interaction paradigms.
Solution Approach 2:
The patent introduces hotspot attributes as an intermediary layer between standard document elements and camera-based interaction functionality. These attributes act as mediators that bridge the gap between existing web technologies and new camera-based gestures, allowing interaction without directly modifying the core markup language structure.
2Adaptability or versatility
If existing content is recreated for camera-based systems, then camera-based interaction capability is improved, but productivity and efficiency deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-defining hotspot attributes and gesture mappings that can be automatically injected into existing document elements. This preparation work is done in advance through attribute injection mechanisms, allowing existing content to be rapidly adapted to camera-based systems without manual recreation, thus maintaining high productivity while enabling new interaction capabilities.
Solution Approach 2:
The patent uses copying by replicating the functionality of traditional interactive elements (buttons, links, etc.) through hotspot attributes on existing document elements. Instead of recreating content in a new format, the system copies the interaction capability onto existing elements via attribute injection, preserving the original content structure while adding camera-based interaction support.
3Ease of operation
If camera-based systems are widely adopted, then ease of operation is improved, but the need for specialized markup languages increases complexity
Solution Approach 1:
The patent makes the system universal by allowing standard web documents to function with both traditional and camera-based interfaces through hotspot attributes. This eliminates the need for users to learn specialized markup languages while maintaining ease of operation, as the same standard documents work across different interaction modes.
Solution Approach 2:
The system applies self-service by automatically injecting hotspot attributes into document elements based on predefined rules and gesture mappings. This automated process eliminates the need for manual configuration or specialized knowledge, allowing the system to configure itself and maintain simplicity while providing advanced camera-based interaction capabilities.

AI summary
A method at a computer system includes obtaining an electronic document comprising document elements, and injecting into the document in association with one of the document elements one or more hotspot attributes, the hotspot attributes defining attributes of a hotspot that is displayable in conjunction with the document element when the document is displayed, the hotspot attributes being associated with predefined physical gestures and respective document actions; such that the hotspot, when displayed as part of a displayed document, indicates that a viewer of the displayed document can interact with the displayed document using the predefined physical gestures (i) performed at a position that overlap a displayed version of the document in a field of view of a camera system and (ii) captured by the camera system, wherein a physical gesture results in a respective document action being performed on the displayed document.
