Touch Interface Tap-Tap Interaction Direction Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch interaction methods for vehicle terminals, such as AVN devices, lack intuitive and efficient ways to manipulate increasing numbers of functions within a limited space, necessitating a new input method that can differentiate between various touch inputs based on direction and timing.
Innovation Solution
A touch interface system that detects and processes tap-tap interactions by recognizing the input direction of subsequent taps within a specified time period, allowing for the execution of specific functions based on the direction and timing of these interactions, including first tap-tap, second tap-tap, third tap-tap, and fourth tap-tap interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional touch interaction methods are used, then the touch interface can be implemented, but the ability to manipulate increasing numbers of functions within limited space is insufficient
Solution Approach 1:
The patent segments touch interactions into distinct types (single tap, double tap, long press, drag) with specific parameters (tap count, press duration, movement distance). This segmentation allows the system to differentiate between multiple functions using the same physical touch space, effectively increasing functional capacity without expanding the touch interface area.
Solution Approach 2:
The patent introduces temporal dimension (timing between taps, duration of press) and spatial dimension (distance between tap points, movement trajectory) to differentiate touch interactions. By adding these dimensions, the system can recognize and execute multiple functions within the same physical touch area, resolving the contradiction between limited space and function manipulation capability.
2Adaptability or versatility
If more functions are added to the vehicle terminal, then functionality is improved, but the complexity of input methods increases
Solution Approach 1:
The patent creates a universal touch interaction framework where a single touch interface can execute multiple functions through variations in interaction parameters (tap count, timing, position, duration). This multi-functionality approach allows the system to handle increasing numbers of functions without adding separate input mechanisms, thereby avoiding increased input method complexity.
Solution Approach 2:
The patent utilizes changes in touch interaction parameters (time interval between taps, spatial distance, press duration) to differentiate between functions. By encoding functional information in parameter variations rather than requiring separate input methods for each function, the system maintains input simplicity while expanding functionality.
3Ease of operation
If tap-tap interaction with direction recognition is implemented, then intuitive manipulation is achieved, but the complexity of touch input detection increases
Solution Approach 1:
The patent applies local quality by recognizing specific directional patterns (e.g., left-right, up-down) in tap sequences and associating each pattern with specific functions. This localized recognition approach makes the interaction intuitive for users while keeping the detection logic organized and manageable, balancing ease of operation with detection complexity.

AI summary
A vehicle terminal may include a touch interface that detects a touch input that is input at a point of a touch panel and when a main controller detects a first tap that is input to the touch panel and then detects at least one second tap within a specified time period with the first tap maintained, the main controller that recognizes a tap-tap interaction based on an input direction of the first tap and the at least one second tap and processes a function that is assigned to the recognized tap-tap interaction.
