Vehicle Touch Panel Input Differentiation for Erroneous Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle manipulation systems using touch panel displays on mobile terminals are prone to erroneous manipulations, such as unintentional locking or unlocking of vehicle doors, due to the difficulty in accurately targeting specific touch inputs.
Innovation Solution
A vehicle manipulation device with a touch panel that detects user inputs and transmits control requests to a communication device for locking, unlocking, or opening/closing vehicle components, utilizing distinct input aspects like tap, long tap, double tap, slide, and gesture inputs to differentiate between intended operations, thereby reducing unintended manipulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel display on a mobile terminal is used for vehicle manipulation, then ease of operation is improved, but reliability deteriorates due to erroneous manipulations
Solution Approach 1:
The patent changes the parameters of touch input by recognizing different aspects of the same touch gesture (duration, pressure, sequence) to differentiate between locking and unlocking operations. This allows the system to maintain ease of touch-based operation while improving reliability by accurately distinguishing user intent through multi-dimensional input analysis
Solution Approach 2:
The system dynamically adjusts the interpretation of touch inputs based on contextual factors such as the current state of the vehicle (locked/unlocked) and the sequence of operations. This dynamic response mechanism enables the same touch panel interface to reliably differentiate between intended locking and unlocking actions by considering the temporal and contextual dynamics of user interactions
2Ease of operation
If simple touch input is used for vehicle control, then ease of operation is improved, but measurement precision deteriorates in detecting user intent
Solution Approach 1:
The patent adds temporal and contextual dimensions to the touch input analysis by measuring the duration, pressure, and sequence of touches. This multi-dimensional approach transforms simple touch coordinates into rich input patterns that enable precise detection of user intent while maintaining the simplicity of touch-based operation
Solution Approach 2:
The system provides feedback by analyzing the sequence and characteristics of touch inputs to determine user intent. By incorporating feedback loops that consider the current vehicle state and the pattern of touches, the system achieves high measurement precision in detecting whether the user intends to lock or unlock the vehicle

AI summary
A vehicle manipulation device is configured to control a vehicle by wirelessly communicating with a communication device in the vehicle, and includes a touch panel, a detection unit, and a request unit. The detection unit is configured to detect an input manipulation of a user with respect to the touch panel. The request unit is configured to transmit a control request for causing the vehicle to perform a first operation to the communication device in response to detection of an input manipulation in a first aspect, the first operation being any one of locking and unlocking of the vehicle, and transmit a control request for causing the vehicle to perform a second operation to the communication device in response to detection of an input manipulation in a second aspect different from the first aspect, the second operation including an operation different from locking and unlocking of the vehicle.
