Electronic Device Accessibility Setup via Segmented UI and Dynamic Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with physical disabilities face challenges during the initial setup process of display devices like TVs or computers, as these devices lack tailored visual and auditory assistance functions.
Innovation Solution
An electronic device with a display, speaker, and processors that executes instructions to provide an initial setting mode for disability assistance, guiding users through a user interface and accessibility menu tailored to their disability type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the initial setup process provides standard visual and auditory interfaces, then the device can be set up by users without disabilities, but users with physical disabilities cannot access or understand the setup process
Solution Approach 1:
The initial setup process is segmented into multiple pathways based on disability type. The system divides users into different categories (visual impairment, hearing impairment, motor impairment, etc.) and provides customized setup sequences for each group, making the complex process manageable and accessible to users with various disabilities
Solution Approach 2:
The interface dynamically adapts its presentation based on the user's disability type. The system changes visual properties (contrast, font size, color schemes) and auditory properties (volume, frequency bands, voice guidance) in real-time according to the selected disability category, enabling the same device to serve diverse user needs without requiring multiple physical devices
2Ease of operation
If the device provides customized accessibility functions for different disability types, then users with disabilities can complete setup successfully, but the device complexity and number of functions increase
Solution Approach 1:
The system performs preliminary classification of user needs at the beginning of the setup process. By asking users to select their disability type upfront, the system can pre-configure appropriate accessibility functions and hide irrelevant ones, making the setup process easier for users while avoiding the need to implement all possible accessibility features simultaneously
Solution Approach 2:
Different accessibility functions are applied locally to specific interface elements based on the user's disability type. For example, high-contrast modes are applied only to text elements for visually impaired users, while frequency band amplification is applied only to speech frequencies for hearing impaired users, rather than applying all modifications globally to all interface elements
3Illumination intensity
If the display device provides visual guidance only, then the interface remains simple, but visually impaired users cannot access the information
Solution Approach 1:
The interface is designed with multi-functionality to serve both visually impaired and non-visually impaired users. The system provides dual-channel information delivery: visual elements (text, icons, color codes) are paired with corresponding auditory elements (voice guidance, sound effects). This universal design allows the same interface to be accessed through either visual or auditory channels depending on the user's needs
Solution Approach 2:
The system utilizes color changes and contrast adjustments as part of its accessibility framework. For visually impaired users, the interface dynamically modifies color schemes (e.g., switching to high-contrast black-and-white mode, adjusting color blindness-friendly palettes). These color modifications work in conjunction with auditory guidance to provide accessible visual feedback
4Power
If the speaker outputs standard frequency range audio, then the audio system remains simple, but hearing impaired users cannot perceive the guidance
Solution Approach 1:
The audio output parameters are dynamically changed based on the user's hearing ability. The system adjusts frequency band amplification (emphasizing speech frequencies for hearing impaired users), modifies volume levels, and alters temporal characteristics of audio output. These parameter changes enable the same speaker to effectively communicate with users across a range of hearing abilities

AI summary
An electronic device includes a display; a speaker; one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the electronic device to, based on an initial setting mode being initiated, control the display to display a first user interface (UI) for guiding a user as to a first initial setting mode for disability assistance; control the speaker to output a first guide voice corresponding to the first UI; based on the first initial setting mode for disability assistance being selected through the first UI, control at least one of the display or the speaker to provide a first accessibility menu including accessibility functions corresponding to a disability type of the user; and based on at least one accessibility function being selected from the first accessibility menu, control the display or the speaker based on the at least one accessibility function.
