Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing systems do not effectively utilize pressure-sensitive input from digitizers, limiting the functionality of graphical user interfaces and requiring users to rely on single-click interpretations, which can be inefficient and inaccurate.
Innovation Solution
Implementing a computer-implemented method that adjusts displayed controls and responds to user interactions based on the pressure and duration of input, distinguishing between normal and hard taps to perform specific functions, and using pressure to select and manipulate objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pressure information from digitizers is utilized, then functionality and control precision of graphical user interfaces is improved, but system complexity increases
Solution Approach 1:
The patent applies parameter changes by utilizing the pressure magnitude parameter from digitizer input to dynamically adjust GUI control behavior. Different pressure thresholds trigger different functions (e.g., light pressure for selection, heavy pressure for activation), allowing the system to differentiate between user intentions based on pressure parameter variations without adding hardware complexity
Solution Approach 2:
The patent implements multi-functionality by enabling a single digitizer input device to perform multiple functions through pressure-based differentiation. The same physical input device can select controls, activate functions, and manipulate objects based solely on varying pressure levels, eliminating the need for additional buttons or switches
2Productivity
If pressure-based control is implemented, then operation speed and accuracy are improved, but processing requirements increase
Solution Approach 1:
The patent applies partial action by implementing progressive pressure thresholds rather than processing all pressure values equally. The system uses threshold-based processing where only significant pressure changes trigger function activations, reducing unnecessary processing while maintaining fast response for critical operations
Solution Approach 2:
The patent implements preliminary action by pre-defining pressure thresholds and their corresponding functions before runtime. This allows the system to quickly compare incoming pressure values against predetermined thresholds rather than performing complex analysis, reducing real-time processing requirements while maintaining accuracy
3Adaptability or versatility
If additional functions are enabled through pressure input, then user interface versatility is improved, but ease of operation may deteriorate due to increased complexity
Solution Approach 1:
The patent applies self-service by allowing the system to automatically interpret user intent based on pressure patterns without requiring explicit configuration. The pressure-based control system adapts to natural user pressing patterns and automatically maps them to appropriate functions, reducing the learning curve despite increased versatility
Data Source
AI summary
The use of pressure-sensitive selection tools in a graphical user interface is disclosed in which the amount of pressure during a selection operation may modify selection behavior. Upon receiving a selection input, the pressure applied is determined and the selection behavior modified. In some embodiments, the number of objects selected is increased when more pressure is applied and decreased when less pressure is applied.
