Accessible Car-Hailing Workflow Using a Second Terminal Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online car-hailing systems are inconvenient for individuals with visual, hearing, or language impairments, as they require manual input of locations and lack personalized communication options.
Innovation Solution
A car-hailing method and device that allows for customized input and communication methods based on user defects, enabling a first terminal to send notifications to a second terminal, which then provides car-hailing information including location and user details, with integrated communication and tracking features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input methods are used for car-hailing, then system complexity is reduced, but ease of operation deteriorates for individuals with disabilities
Solution Approach 1:
The patent introduces a second terminal (such as a smartphone or assistive device) as an intermediary between the first terminal (special needs vehicle) and the car-hailing system. This intermediary handles complex operations like sending car-hailing notifications, providing voice commands, and managing communication, thereby simplifying the user interface for individuals with disabilities while distributing system complexity across multiple components.
2Adaptability or versatility
If standardized communication methods are used, then device complexity is reduced, but adaptability deteriorates for different user needs
Solution Approach 1:
The patent implements dynamic adaptability by allowing the system to adjust communication methods based on user needs. The first terminal can switch between different interaction modes (voice commands, text input, button presses) and the system can modify notification methods, communication protocols, and information presentation formats to suit individual disabilities, making the system flexible and inclusive.
Solution Approach 2:
The first terminal is designed with multi-functional capabilities to serve diverse user needs. It can perform standard car-hailing functions while also providing specialized features like voice recognition, text-to-speech, alternative input methods, and customized notification preferences, allowing a single device to accommodate various disabilities without requiring multiple specialized devices.
3Measurement precision
If location tracking is continuously monitored, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic location monitoring rather than continuous tracking. The system updates the geographical location of the first terminal at regular intervals or based on trigger events (such as when the vehicle stops or changes direction), maintaining sufficient location accuracy for car-hailing purposes while significantly reducing energy consumption compared to continuous GPS monitoring.
Data Source
AI summary
A car-hailing method and device, as well as a computer readable storage medium. The method includes receiving a car-hailing instruction and sending a car-hailing notification to a second terminal associated with a first terminal so that the second terminal sends car-hailing information to a target object according to the car-hailing notification. The car-hailing information includes at least a geographical location of the first terminal, user information and a destination.
