Accessible UI with Auditory Feedback for Moving Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for computing devices, particularly those accessible via mobile devices, often fail to provide effective interaction for visually impaired users with moving objects, as they rely primarily on visual feedback, lacking adequate non-visual cues for navigation and selection.
Innovation Solution
An accessible user interface is developed that utilizes touch sensing and auditory feedback, including vibrations and audible alerts, to enable visually impaired users to select and interact with moving items on a display, with object selection areas being larger than the items themselves, allowing for non-visual feedback and navigation through a combination of touch and auditory responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual feedback is used for user interface interaction, then the interface is intuitive for sighted users, but visually impaired users cannot effectively navigate and select moving objects
Solution Approach 1:
The user interface is designed to serve multiple types of users including both sighted and visually impaired users. The interface provides both visual feedback for sighted users and non-visual feedback (auditory cues, vibration, haptic feedback) for visually impaired users, making it universally accessible across different ability levels
Solution Approach 2:
Accessibility tools and assistive technologies serve as intermediaries between the user and the interface. These tools include screen readers, magnification tools, and accessibility modes that translate visual interface elements into auditory or tactile signals, enabling visually impaired users to interact with moving objects effectively
2Adaptability or versatility
If moving objects are used in the user interface, then the interface is dynamic and engaging, but visually impaired users struggle to detect and select the moving items
Solution Approach 1:
The interface separates the visual moving object into distinct detectable components: the object itself provides visual information for sighted users, while separate non-visual cues (auditory identification, vibration patterns, haptic feedback) provide detection channels for visually impaired users. This segmentation allows each user type to access information through their preferred sensory modality
Solution Approach 2:
The system implements comprehensive feedback mechanisms that respond to user interactions. When a user selects an object, the system provides feedback through multiple channels including auditory confirmation, vibration patterns, and haptic responses, enabling visually impaired users to confirm selections and understand the current state of the interface
3Ease of operation
If object selection areas are made larger, then it is easier to select objects, but the display space is reduced for showing content
Solution Approach 1:
The interface transitions from two-dimensional visual selection to multi-dimensional interaction. Objects can be selected through touch in the physical dimension, auditory proximity in the acoustic dimension, and haptic feedback in the tactile dimension. This allows selection areas to extend beyond traditional visual boundaries, providing easier selection without proportionally reducing display content area

AI summary
A method for facilitating browsing of an accessible user interface is disclosed. The method includes, providing an application for a user device, the user device having an input and a display, the application permitting a user to select an object selection area associated with a moving item using the input of the device; receiving an indication of the object selection area from the user device; identifying the moving item associated with the object selection area; generating a non-visual feedback to the user; and providing the user interface for display on the user device.
