Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for mobile devices lack intuitive feedback mechanisms to help users recognize the correlation between objects and desired operations, leading to potential mistakes during object manipulation.
Innovation Solution
An interactive user interface that controls visual and tactile feedback based on the priority of objects, assigning resistance levels to touch inputs to indicate the correlation between objects and their destination operations, thereby enhancing user recognition and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual and tactile feedback are not provided during object manipulation, then the user interface remains simple, but users cannot intuitively recognize the correlation between objects and desired operations
Solution Approach 1:
The patent implements visual feedback by displaying a shadow image of the object at the destination location during drag operations, and tactile feedback through resistance levels that vary based on object priority. This feedback mechanism provides users with intuitive information about the correlation between objects and desired operations, resolving the contradiction by prioritizing information delivery over system simplicity.
Solution Approach 2:
The patent employs color changes in the shadow image display to indicate different priority levels of objects. High-priority objects display with distinct visual characteristics compared to low-priority objects, enabling users to quickly recognize object importance and expected operation outcomes without complex interface elements.
2Loss of information
If all objects provide uniform feedback during manipulation, then the interface remains consistent, but users cannot distinguish priority differences between objects
Solution Approach 1:
The patent applies local quality by providing differentiated feedback characteristics based on object priority. High-priority objects receive distinct visual feedback (e.g., prominent shadow display) and specific tactile resistance levels, while low-priority objects receive different feedback patterns. This localized differentiation enables users to distinguish object priorities and understand expected operations without complicating the overall interface.
Solution Approach 2:
The patent implements dynamic feedback adjustment where resistance levels and visual characteristics change based on object priority and operation context. The system dynamically modifies feedback properties during manipulation to convey priority information, making the interface adaptive rather than static, thereby improving ease of operation through context-aware discrimination.
3Reliability
If resistance levels are assigned based on object priority, then users can recognize object importance, but the touch input control becomes more complex
Solution Approach 1:
The patent changes the parameter of tactile resistance level based on object priority. High-priority objects are assigned specific resistance levels that provide distinct tactile feedback during drag operations, while low-priority objects receive different resistance levels. This parameter variation enables reliable object differentiation and operation prediction without requiring complex control mechanisms, as the resistance levels are automatically assigned based on pre-determined priority values.

AI summary
Described embodiments relate to an interactive user interface that enables a user to intuitively recognize correlation between a selected object and a desired operation to be performed. Such an interactive user interface may be provided by obtaining a priority of a selected object upon detection of a designated touch input made on the selected object for moving the selected object from a first display region to a second display region in a graphic user interface, determining feedback attributes of the detected designated touch input based on the obtained priority of the selected object, and outputting visual and tactile feedback of the detected designated touch input based on the determined feedback attributes.
