Vehicle UI Routing by Occupant Position for In-Car Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle infotainment systems lack seamless integration with mobile devices for secure and efficient payment transactions, especially when multiple occupants are involved, and there is a need for enhanced user interaction and context-aware payment solutions.
Innovation Solution
An automotive head unit that pairs with mobile devices to extract payment information, uses sensors to identify occupants, and facilitates secure payment transactions through a user-friendly interface, supporting voice commands, biometric authentication, and AI-driven context-aware suggestions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual payment information entry is used, then system simplicity is maintained, but transaction efficiency and user convenience deteriorate
Solution Approach 1:
The patent introduces mobile devices as intermediaries between users and the head unit. Mobile devices store payment information securely and transmit it to the head unit, enabling efficient payments without manually entering details. This intermediary approach resolves the contradiction by automating payment information transfer while maintaining security through the mobile device's secure storage capabilities.
Solution Approach 2:
The system enables self-service payment processing where the mobile device automatically provides payment information to the head unit without requiring manual user input for each transaction. The pre-stored payment information in mobile devices allows users to complete transactions efficiently by simply selecting from available options, thereby improving productivity without proportionally increasing system complexity.
2Speed
If payment information is stored locally in the head unit, then access speed is improved, but security and data privacy deteriorate
Solution Approach 1:
Mobile devices serve as secure intermediaries that store payment information in their own secure elements, separate from the head unit. This distribution of storage responsibility allows the head unit to access payment information quickly when needed while the mobile device maintains security control. The intermediary mobile device resolves the contradiction by enabling fast access without centralizing sensitive data in the head unit.
3Adaptability or versatility
If a single user interface is used, then device simplicity is maintained, but context-awareness and user experience deteriorate
Solution Approach 1:
The patent segments the user interface functionality across multiple devices - the head unit and multiple mobile devices. Each mobile device can display context-aware information relevant to its user, such as payment options for that specific user. This segmentation allows the system to provide personalized, context-aware experiences without requiring a single complex interface, as each device maintains its own simpler, user-specific interface.
4Productivity
If automated payment processing is implemented, then transaction speed is improved, but authentication security and user control deteriorate
Solution Approach 1:
Authentication and payment information setup are performed in advance on mobile devices before transactions occur. Users securely store payment information and authenticate their devices beforehand. During actual transactions, this preliminary authentication enables fast automated processing while maintaining security, as the mobile device's pre-established credentials verify user identity without requiring repeated authentication steps during each transaction.
Data Source
AI summary
An example operation may include one or more of communicating with a service provider via a head unit of a vehicle, capturing sensor data from an interior of the vehicle during an interaction between the service provider and an occupant within the vehicle, determining a location of the occupant within the vehicle based on the sensor data captured from the interior of the vehicle, and displaying data related to the interaction between the service provider and the occupant on a user interface from among a plurality of available user interfaces within the vehicle based on the location of the occupant within the vehicle. An artificial intelligence (AI) model can be trained and/or executed when performing at least one portion of the example operation.
