Touch Sensor Controller Configuration Without Host Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch sensor systems require complex configuration processes that involve host computing devices, which can be inconvenient due to issues like firewall interference, operating system compatibility, and software installation difficulties.
Innovation Solution
A method for configuring touch sensor systems independently of host computing devices, where the touch sensor controller initiates a configuration mode and allows users to set operational settings through specific inputs on the touch panel, such as edge zones or gestures, without needing host device intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If configuration is performed through host computing device software, then operational settings can be configured, but firewall interference, operating system compatibility issues, and software installation difficulties occur
Solution Approach 1:
The configuration functionality is extracted from the host computing device and embedded directly into the touch sensor controller. The controller now includes a configuration mode that can be activated independently, allowing users to configure operational settings without requiring host device software, thereby eliminating firewall interference, OS compatibility issues, and installation difficulties.
Solution Approach 2:
The touch sensor controller performs configuration independently without requiring external host device intervention. The controller activates configuration mode through specific touch inputs (e.g., pressing corners or edges of the touch panel) and allows users to modify settings directly through the touch interface, making the system self-configurable and reducing dependency on host software.
2Adaptability or versatility
If multiple communication channels are available for configuration, then flexibility is improved, but security is reduced due to increased attack surfaces
Solution Approach 1:
The configuration functionality is extracted from the host computing device communication channel and embedded within the touch sensor controller itself. This eliminates the need for complex software communication between host and controller, reducing the attack surface while maintaining configuration flexibility through direct touch panel interaction.
Solution Approach 2:
The touch panel itself serves as the intermediary interface for configuration, replacing the need for separate communication channels between host device and controller. Users interact directly with the controller through touch inputs on the panel, which the controller interprets to modify settings, thereby securing the system by limiting communication to the essential touch interface only.

AI summary
A method is provided for configuring a touch sensor controller coupled to a touch panel and a host computing device. The method includes receiving, by the controller, first input for starting a configuration mode of operation. The first input may be received independent of the host computing device. The controller initiates the configuration mode of operation responsive to the first input. The controller receives at least one second input via the touch panel for configuring at least one operational setting of the controller. The method also includes configuring, by the controller, the at least one operational setting according to the received at least one second input.
