Virtual Input Mode Transition Across Multi-Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of virtual input devices on information handling systems, such as tablets, lacks the physical feedback of traditional input devices, leading to slower and more error-prone interactions, especially in multi-display environments where coordinating touch inputs across different displays disrupts workflow and requires additional limb movements.
Innovation Solution
An information handling system that automatically manages virtual input devices by transitioning between touch and pointer modes based on context, using a mode selector to interpret end-user inputs such as touches, voice commands, and gestures, allowing seamless interactions across multiple displays without interrupting the user's workflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If virtual input devices are used on tablet information handling systems, then system portability and compactness are improved, but input speed and accuracy deteriorate due to lack of physical feedback
Solution Approach 1:
The patent introduces haptic feedback mechanisms as an intermediary between the virtual input device and the user. The haptic feedback generator creates physical sensations (vibrations, resistance forces) that simulate the tactile experience of traditional physical input devices, thereby maintaining input speed and accuracy while preserving the compactness of the tablet system.
2Volume of moving object
If virtual input devices are used on tablet information handling systems, then system portability is improved, but input accuracy deteriorates due to lack of physical feedback
Solution Approach 1:
The haptic feedback generator serves as a mediator that provides tactile confirmation of user inputs. By generating physical feedback sensations, it enables users to verify their input actions through touch, thereby improving input accuracy and reliability while maintaining the virtual input device's compact form factor.
3Adaptability or versatility
If end users coordinate touch inputs across multiple displays, then visual information presentation is improved, but workflow efficiency deteriorates due to disrupted workflow and additional limb movements
Solution Approach 1:
The patent implements a universal input interface that automatically adapts to multi-display configurations. The system detects when multiple displays are active and automatically coordinates touch inputs across them, allowing users to interact with any display using the same touch gestures without needing to manually configure or switch between different input modes, thereby maintaining workflow efficiency while enabling multi-display versatility.

AI summary
An information handling system presents visual images at plural display devices and moves the visual images at the display devices responsive to touches made at one or more of the display devices with movement managed in a point mode or a touch mode as selected by one or more predetermined inputs. In the touch mode, the visual image moves as the touch moves. At detection of the predetermined input to select the point mode, the visual image moves a greater distance than the touch movement so that the end user is able to move the visual image between separate display devices.
