Voice Navigation Module for Mobile Interface Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interfaces designed for home devices are not suitable for mobile devices, and operating them while distracted or unable to view and touch the device is challenging.
Innovation Solution
Implementing a voice navigation module on mobile devices that assigns sequence indications to each control, allowing users to navigate the interface verbally and scroll or change pages to access controls outside the viewable area, with sequence control maps stored for consistency and memorability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical user interface designed for home devices is used on mobile devices, then the interface design is consistent and familiar to users, but the interface is not suitable for mobile device operation and is difficult to operate while distracted or unable to view and touch the device
Solution Approach 1:
The system dynamically adapts the user interface by switching between different interaction modes (visual touch interface and voice-controlled interface) based on the current usage scenario. When the device detects that the user is distracted or cannot view the screen, it automatically transitions from a static visual interface to a dynamic voice-controlled interface, allowing the same device to serve multiple operational contexts effectively
Solution Approach 2:
The system changes the interaction parameters of the user interface by introducing voice commands as an alternative input method. Instead of requiring visual attention and manual touch operations, the interface accepts auditory input parameters, transforming the interaction mode from visual-manual to auditory-verbal while maintaining the same underlying control functionality
2Ease of operation
If voice navigation is implemented to allow operation while distracted, then ease of operation improves, but device complexity increases due to sequence control maps and voice navigation module
Solution Approach 1:
The voice navigation module serves multiple functions within a single integrated system: it provides alternative input methods for distracted users, maintains consistency across different device screens through sequence control maps, and enables hands-free operation. This multi-functionality justifies the added complexity by delivering substantial operational benefits across various usage scenarios
Solution Approach 2:
The system performs preliminary actions by pre-defining sequence control maps that assign specific meanings to voice commands based on the current screen context. These sequences are established in advance, allowing the voice navigation system to automatically interpret and execute user intent without requiring real-time complex processing, thereby reducing the operational burden on the user
3Ease of operation
If sequence control maps are stored for consistency and memorability, then ease of operation improves through memorization, but loss of information increases if controls are outside the viewable area
Solution Approach 1:
The voice navigation system provides continuous feedback to the user by announcing the current screen context and the sequence of available controls. This auditory feedback compensates for the user's inability to visually see controls outside the current viewable area, ensuring that no information is lost while maintaining the benefits of sequence memorization for efficient operation
Data Source
AI summary
A system may include a mobile computing device configured to receive voice input; identify, in the voice input, a navigate command including a sequence indication; determine, based on a sequence control map, a control of a user interface corresponding to the sequence indication; and activate the control of the user interface corresponding to the sequence indication.
