Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-sensitive displays are limited in their ability to receive and process touch inputs, often restricting functionality due to poor discrimination between intentional and inadvertent touches, and requiring unnatural user interactions, with sub-optimal layout and device postures compromising the utilization of touch-sensitive display advantages.
Innovation Solution
A touch-sensitive electronic display device with interface software that allows for inertial movement of objects across multiple screens, dynamically masking regions to differentiate between hand and pen touch inputs, and correcting for partial or edge-violating movements to ensure seamless interaction and intuitive use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one type of touch input is permitted, then device complexity is reduced, but functionality is limited
Solution Approach 1:
The system changes the parameter of touch input recognition by detecting characteristics such as contact area size, pressure, and touch duration to differentiate between hand touches and pen touches. This allows multiple input types to be permitted on the same device without requiring separate hardware systems, thereby improving functionality while maintaining relatively simple device architecture.
2Ease of operation
If the display allows free movement of objects across screens, then ease of operation is improved, but discrimination between intentional and inadvertent touches deteriorates
Solution Approach 1:
The system applies different quality characteristics to different regions of the display by dynamically masking specific areas based on detected touch patterns. When a pen touch is detected, the system masks surrounding regions to prevent inadvertent hand touches from triggering actions, while allowing the intended pen input region to remain responsive. This local differentiation maintains ease of operation for intentional inputs while improving reliability by blocking inadvertent touches.
3Measurement precision
If dynamic masking is applied to discriminate input types, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system employs self-service by utilizing the inherent characteristics of the touch input itself (contact area, pressure, duration) to automatically differentiate between hand and pen touches. The interface software analyzes these intrinsic properties and applies appropriate masking dynamically, without requiring external assistance or complex additional hardware. This approach improves measurement precision through intelligent analysis of existing touch data while minimizing the increase in device complexity by leveraging software-based solutions.

AI summary
A touch-sensitive electronic display device including one or more touch-sensitive display screens and interface software. The touch-sensitive display screen(s) and interface software are configured to be responsive to touch inputs and, in the case of a multi-screen workspace, the interface software is operable to allow inputs made in connection with a first screen to generate an inertial movement of a displayed object which results in the object moving to and coming to rest on another of the screens. The touch-sensitive screen and interface software may also be configured to receive hand touch inputs and pen touch inputs, with the interface software being operable to dynamically mask regions of the touch-sensitive display to discriminate between or selectively permit/reject different types of inputs.
