Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with touch-sensitive displays face issues such as non-responsiveness due to moisture, ghost touches, and limited gestures, especially on large or small displays, leading to hindered user interaction and experience.
Innovation Solution
The method and electronic device enable control functionality on the rear end by detecting non-responsiveness and enabling back tap gestures through dynamic tile partitioning, user gesture classification, and functionality determination using machine learning models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to provide better user interface, then the display area and functionality are improved, but the user's ability to perform gestures on the display becomes difficult
Solution Approach 1:
The patent extends the touch-sensitive control area from the front display surface to the rear surface of the electronic device. This dimensional extension allows users to perform gestures on the rear surface, which is mapped to corresponding functions on the front display, thereby maintaining ease of operation even with larger display sizes.
Solution Approach 2:
The rear surface is divided into multiple zones or regions that correspond to different functional areas on the front display. This segmentation allows specific gestures on different parts of the rear surface to trigger specific functions, providing fine-grained control despite the large display area.
2Adaptability or versatility
If the display is made touch-sensitive for user interaction, then the user interface capability is improved, but the display becomes non-responsive under certain conditions such as moisture, ghost touches, or when wearing non-conductive accessories
Solution Approach 1:
The patent introduces the rear surface as an intermediary control interface. When the front display becomes non-responsive due to moisture, ghost touches, or non-conductive accessories, users can interact with the device through the rear surface, which uses different sensing mechanisms (such as pressure or capacitance sensors embedded in the rear casing) to detect gestures and translate them to front display actions.
Solution Approach 2:
The system changes the sensing parameters and detection methods between the front display and rear surface. While the front display uses standard capacitive touch sensing, the rear surface employs alternative sensing parameters such as pressure sensitivity or different capacitance measurement techniques that are not affected by moisture or non-conductive materials, thereby maintaining reliability across different usage conditions.
3Area of stationary object
If the display size is reduced for portability, then the device compactness is improved, but the user experience in applications such as gaming and control operation becomes difficult
Solution Approach 1:
The patent extends the control interface to the rear surface, effectively creating a second control plane. This allows users to perform gestures with both hands on the rear surface simultaneously, providing a larger effective control area that compensates for the small front display size, particularly beneficial for gaming and multi-control scenarios.
Solution Approach 2:
The patent merges the control functions of the front display with the rear surface, creating a unified dual-sided control system. Gestures on the rear surface are mapped to corresponding functions on the front display, effectively doubling the available control real estate while maintaining a compact form factor.

AI summary
Embodiments are directed to providing control functionality of a display of an electronic device. The method includes determining, by the electronic device, an event and partitioning, by the electronic device, a rear side of the electronic device into dynamic tiles based on multiple parameters associated with the display, based on determining the event. The method also includes detecting, by the electronic device, a user gesture on the dynamic tile on the rear side of the electronic device and classifying, by the electronic device, the detected gesture into a gesture category. Further, the method includes determining, by the electronic device, a functionality based on the gesture on the rear side of the electronic device and the corresponding gesture category. The method includes controlling, by the electronic device, the functionality on the display of the electronic device.
