In-Vehicle Payment Code Display Based on Passenger Presence

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In-vehicle display systems struggle to appropriately display payment codes, making it difficult for drivers and passengers to read them while the vehicle is in operation, especially when only one person is present.

Innovation Solution

An information processing apparatus that controls the display of payment codes on separate displays for drivers and passengers, hiding the code from the driver's display when no passenger is present and showing it on the passenger's display while the vehicle is in operation, and vice versa.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If payment code is displayed on the driver's display while the vehicle is in operation, then the driver can access payment functions, but it creates safety risks and distraction

Engineering Contradiction:

Improvepayment code accessibilityVSAvoiddriver distraction

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The in-vehicle display system is segmented into multiple independent displays (driver's display and passenger's display). The payment code display function is specifically assigned to the passenger's display when a passenger is present, separating the payment code visibility from the driver's direct line of sight and reducing distraction while maintaining accessibility.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If payment code is not displayed when no passenger is present, then driver distraction is minimized, but payment functionality becomes unavailable

Engineering Contradiction:

Improvedriver distractionVSAvoidpayment function availability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts its behavior based on the detected presence of a passenger. When a passenger is detected, the payment code is displayed on the passenger's display. When no passenger is present, the system switches to allowing the driver to access payment functions through voice commands or other hands-free methods, ensuring payment functionality remains available while adapting to the current occupancy state.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If payment code is displayed on a single shared display, then device complexity is reduced, but readability and usability are compromised

Engineering Contradiction:

Improvedisplay system structureVSAvoidcode readability

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

Different displays within the vehicle are assigned different functions based on their location and user. The passenger's display is optimized for displaying payment codes with high readability, while the driver's display maintains its primary driving information function. This local specialization of display functions improves code readability without significantly increasing overall system complexity.

Inventive Principle:

Principle #3Local quality

AI summary

The in-vehicle display includes a first display for a driver of a vehicle and a second display for a fellow passenger of the vehicle. An information processing apparatus does not display payment code on the in-vehicle display while the vehicle is in operation when no fellow passenger is present in the vehicle. The information processing apparatus displays the payment code on the second display while the vehicle is in operation when a fellow passenger is present in the vehicle.
