Pressure-Sensitive Touch Screen Visual Feedback Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure-sensitive touch screen systems provide visual feedback at a location remote from the touch location, causing user interaction inefficiencies due to obscured feedback and inefficient use of screen real estate, particularly on handheld devices.
Innovation Solution
A data processing system with a pressure-sensitive touch screen where visual feedback is centered around the touch location on the screen, with the size of the feedback indication dependent on the contact area, ensuring it remains visible regardless of the user's finger or stylus size, and can include attributes like size, color, or contrast that change with pressure magnitude.

Engineering Contradiction Analysis
1Reliability
If visual feedback is provided at a location remote from the touch location, then the visual feedback is not obscured by the user's hand or finger, but the user must keep an eye on both locations and screen real estate is inefficiently used
Solution Approach 1:
The patent merges the touch input location and visual feedback location into the same position on the screen. The visual feedback is rendered at the precise location where the user touches the screen, combining the input and output functions at a single spatial coordinate, thereby eliminating the need to monitor separate locations and improving interaction efficiency

3Reliability
If the visual indication size is made dependent on the contact area size, then the visual indication remains visible regardless of finger or stylus size, but the system becomes more complex
Solution Approach 1:
The system automatically determines the contact area size through the touch screen's pressure-sensitive capabilities and uses this information to dynamically adjust the visual indication size. The system serves itself by leveraging existing sensor data to automatically adapt the feedback visualization, eliminating the need for manual configuration or complex additional hardware

AI summary
A data processing system, e.g., a remote control device, has a pressure-sensitive touch screen arranged over a display monitor. The monitor provides a visual indication depending on a magnitude of a pressure registered by the touch screen. The indication is rendered as centered on the touch area and has an attribute that depends on the pressure exerted.
