Touch Selection Manager Using Pressure and Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interfaces lack the ability to provide granular and dynamic selection of content based on the characteristics of contact instruments, such as pressure and orientation, which limits the precision and flexibility of content selection.
Innovation Solution
The system enhances touch selections by using a selection manager that determines the characteristics of contact instruments, such as pressure and orientation, to generate parameters for selection commands, allowing for the precise selection and modification of content portions, and incorporates context information to refine the selection scope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional touch interface selection methods are used (tap, drag, double-click), then the interface remains simple and easy to operate, but the granularity and precision of content selection is limited
Solution Approach 1:
The patent applies parameter changes by utilizing pressure sensitivity and orientation detection of the contact instrument. Different pressure levels trigger different selection behaviors (e.g., light tap selects word, firm press selects paragraph), and orientation changes modify selection scope. This resolves the contradiction by encoding multiple selection granularities through physical parameter variations rather than interface complexity increases.
Solution Approach 2:
The system implements self-service by automatically determining selection scope based on contact instrument characteristics without requiring user configuration. The system autonomously interprets pressure and orientation data to select appropriate content portions, eliminating the need for complex menu selections or mode switching while achieving precise selection control.
2Measurement precision
If multiple input devices and complex gestures are used to achieve granular selection, then selection precision improves, but ease of operation deteriorates
Solution Approach 1:
The patent makes the contact instrument universal by enabling it to perform multiple selection functions through pressure and orientation variations. A single instrument can select characters, words, sentences, paragraphs, or custom regions without requiring different tools or complex gesture sequences. This multi-functionality approach maintains operational simplicity while achieving fine-grained selection control.
3Adaptability or versatility
If selection scope is fixed by standard gestures, then interface simplicity is maintained, but adaptability to different selection needs deteriorates
Solution Approach 1:
The patent implements dynamics by making selection scope variable based on real-time contact instrument characteristics. As pressure changes or orientation shifts during the selection process, the selection scope dynamically adjusts to match user intent. This dynamic adaptation allows flexible selection of different content portions without requiring pre-defined gesture sets or complex configuration mechanisms.

AI summary
Methods for enhancing touch selections for content are performed by systems and devices. Users apply a contact instrument such as a finger, stylus, or pen to a touch interface to select content displayed via a user interface. Different amounts of the content are selected based on the characteristics of the contact instrument application to the touch interface and displayed to the user. Additionally, selected portions of content can be expanded or reduced by altering the application of the contact instrument, such as changing pressure or orientation, and by receiving other selection modifying inputs from other input devices. Characteristics of interaction for contact instruments are determined and applied to selection commands by the systems and devices. Context information related to the content is also used in determining the scope of selections.
