TOUCH SENSING IN NON-CAPACITIVE TOUCH MODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17806233 titled 'TOUCH SENSING IN NON-CAPACITIVE TOUCH MODES
Simplified Explanation
The patent application describes a method for improving touch sensing on electronic devices when the capacitive touch sensor system is not functioning properly. Here are the key points:
- The method detects when the capacitive touch sensor system is not working in a specific user context.
- It disables touch sensing using the capacitive touch sensor system.
- It enables touch sensing using an alternative sensor system, which can include a fingerprint sensor system, an optical sensor system, and a force sensor system.
- Touch sensing using the alternative sensor system is limited to a designated portion in the graphical user interface to enhance the user experience.
- The designated portion aligns with the active area of the fingerprint sensor system.
- User interface controls are arranged in an array of tiles.
Potential applications of this technology:
- Mobile devices: This method can be applied to smartphones and tablets to improve touch sensing when the capacitive touch sensor is not working properly.
- Wearable devices: Smartwatches and fitness trackers can benefit from this technology to ensure accurate touch sensing even when the capacitive touch sensor is inoperable.
- Automotive displays: Touchscreens in cars can use this method to provide alternative touch sensing options when the capacitive touch sensor is not functioning correctly.
Problems solved by this technology:
- Inoperable capacitive touch sensor: When the capacitive touch sensor system is not working, this method provides an alternative sensor system to ensure touch sensing functionality.
- User frustration: By limiting touch sensing to a designated portion of the interface, the user experience is improved, preventing frustration caused by inaccurate or non-responsive touch inputs.
Benefits of this technology:
- Enhanced user experience: By enabling touch sensing using alternative sensors, the method ensures that users can still interact with the device even when the capacitive touch sensor is not functioning properly.
- Improved accuracy: The designated portion for touch sensing using the alternative sensor system aligns with the active area of the fingerprint sensor, providing accurate touch inputs.
- Versatility: The method allows for the use of different alternative sensor systems, such as fingerprint, optical, or force sensors, providing flexibility in touch sensing options.
Original Abstract Submitted
In some implementations, a method may involve detecting that touch sensing using a capacitive touch sensor system is inoperable in a given user context. Touch sensing using the capacitive touch sensor is disabled and touch sensing using an alternative sensor system is enabled. The alternative sensor system may include a fingerprint sensor system, an optical sensor system, and a force sensor system. Touch sensing using the alternative sensor system may be limited to a designated portion in a graphical user interface for improved user experience. In some implementations, the designated portion may be coextensive with an active area of the fingerprint sensor system and user interface controls may be arranged into an array of tiles.
