Gesture-Based Context-Sensitive Help and Search for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in configuring mobile device applications and accessing help or search functions, often requiring manual effort and time, especially when unfamiliar with configuration options or needing information related to the content they are viewing.
Innovation Solution
Implementing a system that detects physical gestures on mobile devices to invoke context-sensitive help or search functionalities, allowing users to quickly access relevant information without manual input, using sensors like accelerometers and gyroscopes to recognize predefined gestures for help or search actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually configure application settings or initiate search queries through traditional interfaces, then the device provides comprehensive functionality, but the ease of operation deteriorates due to complex configuration processes and time-consuming manual input
Solution Approach 1:
The system pre-configures gesture commands that correspond to common user needs (help, search, configuration). When a user performs a gesture, the system has already prepared the relevant context and can immediately execute the appropriate action without requiring the user to navigate through menus or type queries, thus reducing time consumption while maintaining ease of operation
Solution Approach 2:
The system automatically detects the current application context and autonomously determines what help or search information would be most relevant. Instead of requiring users to manually search for help topics or formulate search queries, the system serves itself by identifying context (such as which application is active, what screen is displayed) and providing appropriately tailored assistance, thereby reducing both time consumption and operational complexity
2Reliability
If users access help features or search functionality through traditional manual methods, then the system provides comprehensive information access, but user error increases due to unfamiliarity with configuration options and help features
Solution Approach 1:
The system pre-establishes gesture-command mappings for common operations (help, search, configuration). Users learn a limited set of simple gestures rather than navigating complex menus or understanding technical configuration options. This preliminary setup reduces user error by eliminating unfamiliar interface elements while maintaining access to comprehensive functionality
Solution Approach 2:
The system automatically identifies the current context (application, screen, operational state) and provides help or search information tailored to that specific situation without requiring users to understand system architecture or configuration options. This context-aware self-service reduces user error by providing relevant information directly, while the underlying complexity of context detection and information retrieval remains hidden from the user

AI summary
Gesture based, context sensitive help and search functionalities are provided for application programs on a mobile device. In response to detecting movement at a mobile device in the form of a gesture, it is determined whether the movement corresponds to a predetermined gesture for invoking a help or search functionality. When the movement corresponds to a predetermined gesture, a current context of mobile device is identified and help content associated with the identified current context is retrieved for the help functionality, or a search query associated with the context is invoked and search results are obtained for a search functionality, for presentation to the user of the mobile device.
