Pressure-Sensitive Touch Input Routing for Multi-Application Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-enabled devices lack an efficient method to navigate and direct user input between multiple applications displayed on a pressure-sensitive touch screen, relying on traditional focus techniques that require rearrangement of interfaces.
Innovation Solution
A system that receives touch input on a pressure-sensitive touch-enabled screen, identifies applications at the touch location, and directs input to the selected application based on the applied pressure level, allowing multiple applications to be interacted with without rearranging the display order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional focus techniques are used to navigate between applications, then the system can direct input to a single active application, but the user interface becomes complex and requires rearrangement of interfaces to access different applications
Solution Approach 1:
The patent changes the pressure parameter of the touch input to differentiate between applications. By detecting different pressure levels at the same touch location, the system directs input to different applications without requiring interface rearrangement. This resolves the contradiction by adding a new dimension (pressure) for navigation while maintaining the visual interface layout.
2Adaptability or versatility
If multiple applications are displayed at the same location on the screen, then the user can access multiple functions simultaneously, but it becomes difficult to direct input to the correct application
Solution Approach 1:
The system uses pressure level as an additional parameter to disambiguate which application should receive input when multiple applications are displayed at the same location. Different applications are assigned to different pressure ranges, allowing accurate input direction despite spatial overlap of application interfaces.
3Reliability
If the display order of applications is rearranged to change focus, then the active application can be clearly identified, but the user experience is disrupted and navigation becomes less seamless
Solution Approach 1:
Instead of rearranging the display order to indicate focus, the system uses pressure sensitivity to identify the intended application. The display layout remains stable and continuous, while pressure level serves as the focus selection mechanism, maintaining user experience continuity while reliably identifying the active application.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless navigation and input direction to the desired application by using pressure sensitivity to differentiate interactions with multiple applications overlaid on the same location, enhancing user experience without the need to change the focus or rearrange the interface.
Implementation Method 1
The reflection is caught with sensors or cameras that send the data to software which dictates response to the touch, depending on the type of reflection measured.
Implementation Method 2
Touch enabled devices can also be made pressure-sensitive by the addition of a pressure-sensitive coating that flexes differently depending on how firmly it is pressed, altering the reflection.
Data Source
AI summary
An approach is provided to direct data to different applications based upon the amount of pressure applied by a user of a pressure sensitive touch-enabled screen. In this approach, a touch input is received at a location of the pressure sensitive touch-enabled screen. The various applications currently being displayed at the location are identified along with the physical pressure level (amount of pressure applied) at the location on the pressure sensitive touch-enabled screen. One of the applications running on the device is selected based on the amount of pressure applied and the touch-based input provided by the user is directed to the selected application.
