Touch Input Control with Directional Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to scroll or control digital content on display devices, particularly portable ones, as they need to repeatedly perform touch inputs, which can be difficult to manage while gripping the device stably.
Innovation Solution
A display device with a sensor unit to detect continuous touch inputs and a tactile feedback unit that generates feedback based on the initial drag direction, allowing one-way control of digital content in the direction of the initial touch input, enabling stable grip and continuous scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user performs multiple touch inputs to scroll or control digital content on a display device, then the content can be navigated, but the user convenience deteriorates due to repeated contact/release operations and difficulty in stable gripping
Solution Approach 1:
The patent implements continuous touch input recognition where the system maintains detection during the entire touch duration, extracting multiple drag directions from a single continuous contact. This eliminates the need for repeated contact-release operations while preserving stable gripping, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent segments the continuous touch input into multiple directional components (first drag direction and second drag direction) based on touch movement trajectory. By analyzing different segments of the touch path, the system identifies scroll direction and control actions without requiring separate touch operations, thereby improving user convenience while managing input complexity
2Productivity
If the touch sensitive region is limited to the screen region, then the display device structure remains simple, but the user must perform several touch inputs to check digital content in large size
Solution Approach 1:
The system enables continuous content navigation through a single continuous touch input by recognizing multiple drag directions within one touch event. This allows the user to scroll through large digital content efficiently without performing multiple separate touch operations, directly addressing the contradiction between productivity and ease of operation
3Adaptability or versatility
If the display device provides scroll function through touch input, then digital content can be accessed, but the user experiences inconvenience from repeated contact/release operations
Solution Approach 1:
The patent segments the touch input into meaningful action components: initial touch phase for determining drag direction, continuous drag phase for content navigation, and release phase for action confirmation. This segmentation allows the system to provide versatile content access while maintaining operation simplicity by interpreting complex touch patterns as intentional user actions
Solution Approach 2:
The system provides tactile feedback to the user during the touch input process, confirming the recognized drag direction and control actions. This feedback mechanism enhances the ease of operation by giving users immediate confirmation that their touch input is correctly interpreted, while maintaining adaptability for various content navigation needs

AI summary
A display device and controlling method thereof are disclosed. The present invention includes displaying object on display unit, detecting contact with region of displayed object on display unit, detecting first touch input of dragging displayed object in top-bottom or right-left direction by maintaining contact, controlling object in direction of one-way control in response to first touch input, and generating tactile feedback on first touch input, wherein direction of one-way control is set up by initial drag direction of first touch input, wherein object is controlled to correspond to direction component of one-way control included in first touch input, and wherein when first touch input includes first drag performed in direction of one-way control and second drag performed in direction opposite to one-way control direction, tactile feedback on either first drag or second drag is generated.
