In-Vehicle Mobile Operation Restriction via Driver Seat Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for preventing terminal operation during driving are inadequate as they fail to accurately identify the communication terminal of the driving user, leading to insufficient operation restriction for the driver's seat occupant.
Innovation Solution
An information processing device equipped with a process execution unit, an imaging unit, and an operation restriction unit that captures images of the vehicle's interior to determine if the operator is seated on the driver's seat, restricting operations when necessary, and adjusts based on vehicle movement and autonomous driving status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If account information and communication terminal identification are used to restrict operations, then operation restriction can be implemented, but accurate identification of the driving user's terminal cannot be ensured
Solution Approach 1:
The patent replaces the mechanical/manual method of terminal identification (relying on account information and user input) with an optical imaging system. The imaging unit captures images of the communication terminal, and image processing automatically identifies the terminal without requiring manual account verification, thereby ensuring accurate identification while maintaining operation restriction functionality.
Solution Approach 2:
The patent creates a visual copy (image) of the communication terminal using the imaging unit. By capturing and analyzing the visual appearance of the terminal rather than relying on account information, the system can accurately identify the driving user's terminal and apply appropriate operation restrictions.
2Measurement precision
If the imaging unit captures images to determine driver's seat occupancy, then accurate identification of driver status is achieved, but device complexity increases
Solution Approach 1:
The imaging unit serves multiple functions: it captures images for terminal identification, determines driver's seat occupancy, and verifies driver status. By using a single imaging component for multiple purposes, the patent achieves accurate driver status identification without proportionally increasing device complexity.
Solution Approach 2:
The system uses the existing imaging unit (already present for terminal identification) to additionally perform driver status detection. The same hardware resource serves dual purposes, avoiding the need for separate sensors or detection devices and thereby minimizing the increase in device complexity.

AI summary
The mobile device is provided with an operation restriction unit, and the operation restriction unit determines which seat of the vehicle is being operated from the captured image of the back camera. When determining that the captured image is captured by the driver's seat, the operation restriction unit restricts the operation of the process execution unit. Accordingly, in the mobile device, it is possible to prevent the mobile device from being operated in the driver's seat, which is appropriately restricted from being operated in the driver's seat in a vehicle or the like.
