Sliding Touch Input Message Filtering for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently filtering messages, particularly when operated with one hand, as current methods require finicky adjustments and are prone to errors, especially in busy environments.
Innovation Solution
A mobile electronic device with a touchscreen that detects sliding touch inputs with a first portion in one direction and a second portion in another, applying filtering conditions to filter messages by type or read status, allowing for ergonomic one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional message filtering methods are used, then messages can be filtered by type or read status, but the operation becomes finicky and error-prone, especially when operated with one hand
Solution Approach 1:
The patent changes the parameter of interaction from complex multi-step menu navigation to simple sliding distance measurement. Different sliding distances (parameters) correspond to different message types, making the operation intuitive and accurate. For example, sliding a first distance selects unread messages, while sliding a second distance selects read messages, eliminating ambiguity in one-handed operation.
Solution Approach 2:
The patent replaces the mechanical interaction of precise menu selection and button pressing with a tactile sliding gesture on the touchscreen. This substitution allows users to interact with the device using simple finger movements rather than complex manual operations, significantly improving ease of use while maintaining accuracy through distance-based gesture recognition.
2Productivity
If complex menu navigation is used for filtering messages, then filtering functionality can be achieved, but the number of steps and complexity increases
Solution Approach 1:
The patent segments the message filtering function into distinct sliding distance ranges, where each range corresponds to a specific message type or read status. This segmentation allows the system to handle different filtering tasks through simple, differentiated gestures rather than complex nested menus, reducing operational complexity while maintaining functionality.
Solution Approach 2:
Instead of requiring users to navigate through menus to access filtering options, the patent inverts the approach by having filtering options actively respond to simple sliding gestures. The system interprets the direction and distance of the slide to automatically apply the appropriate filter, eliminating the need for complex navigation steps.
3Ease of operation
If one-handed operation is supported, then ease of use improves, but precision and accuracy of gesture recognition becomes more challenging
Solution Approach 1:
The patent uses the parameter of sliding distance as a robust indicator for gesture recognition. By measuring how far the user slides their finger across the touchscreen, the system can accurately determine the intended message type or filter criterion even during one-handed operation, where gesture precision might otherwise be compromised.
Solution Approach 2:
The patent introduces the sliding gesture as an intermediary between the user's intent and the system's response. This intermediary gesture provides a clear, measurable signal that bridges the gap between casual one-handed touching and precise command execution, allowing the system to accurately interpret user intent without requiring fine motor control.

AI summary
A device and method for filtering messages using sliding touch input are provided. The device comprises a processor; a memory storing messages of different types, at least a subset of the messages designated as unread messages; and a touchscreen including a display. A sliding touch input is detected at the touchscreen, the sliding touch input comprising a first portion in a first direction and a second portion in a second direction such that the sliding touch input includes a change in direction. In response, the messages are filtered according to one or more of a first filtering condition associated with the first portion and a second filtering condition associated with the second portion, to filter the messages according to one or more of type and a read status.
