Tablet Display Mapping for Intuitive Multi-Screen Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Using a tablet apparatus to switch between multiple displays connected to an information processing apparatus is cumbersome, as the operation surface corresponds to a single display, making it difficult to intuitively select and switch between individual displays.
Innovation Solution
A display switching system that supports multiple displays through an input apparatus, allowing intuitive switching based on gesture operations using an electronic pen to indicate positions and change displays or operation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation surface of the tablet apparatus corresponds to a single display, then the mapping between input and display is simple, but switching between multiple displays becomes cumbersome and non-intuitive
Solution Approach 1:
The tablet apparatus is designed to serve multiple functions: it can correspond to individual displays separately or to a composite large display formed by multiple displays arranged in a matrix. This multi-functionality allows the same input device to adapt to different display configurations without requiring separate switching mechanisms, thereby improving ease of operation while managing device complexity.
Solution Approach 2:
Multiple individual displays arranged in a matrix are merged to form a single composite large display. The tablet apparatus then corresponds to this composite display as a whole, allowing users to input positions on the large display screen and have content displayed across multiple physical displays simultaneously. This merging eliminates the need for complex switching between individual displays.
2Area of stationary object
If multiple displays are connected to expand the display area, then the display capability is improved, but the operation becomes cumbersome as the tablet cannot intuitively select individual displays
Solution Approach 1:
The composite large display is segmented into multiple individual display regions, each corresponding to a physical display in the matrix. When a user performs a gesture on the tablet apparatus, the system can identify which segmented region the gesture targets and route the input to the corresponding physical display. This segmentation allows intuitive selection of individual displays while maintaining the benefits of the expanded display area.
Solution Approach 2:
The system adds a spatial dimension to the mapping between tablet input and display output. By arranging displays in a matrix and allowing the tablet to correspond to the composite 2D layout, users can intuitively select individual displays by gesturing toward the corresponding region in the composite display space, making display selection as natural as pointing on a large screen.
3Measurement precision
If the tablet apparatus corresponds to a large composite display, then position indication on the large display is enabled, but determining whether input is for position indication or display switching becomes difficult
Solution Approach 1:
The system uses periodic or sequential processing of gesture inputs, where gestures are evaluated in a specific order or with specific timing characteristics. By analyzing the temporal patterns and characteristics of gestures (such as duration, speed, or sequence), the system can distinguish between position indication gestures and display switching gestures, resolving the ambiguity while maintaining precise position indication capability.
Solution Approach 2:
The system incorporates feedback mechanisms to clarify the intended function of gestures. This may include visual feedback showing the current target display or composite display state, or contextual feedback that helps the user understand whether their gesture will result in position indication or display switching. This feedback reduces ambiguity and improves the system's ability to correctly interpret user intent.

AI summary
A display switching system is provided to support using, through an input apparatus such as a tablet apparatus, a plurality of displays connected to an information processing apparatus. The input apparatus indicates a position on one of the plurality of displays. The information processing apparatus includes an association unit which associates an input area of the input apparatus with a display area of one of the plurality of displays; a determination unit which determines whether an input from the input apparatus is a position indication input or a change instruction input; and a changing unit which changes an association between the input apparatus and one of the plurality of displays based on the change instruction input. When the input from the input apparatus is the change instruction input, the changing unit changes the association between the input apparatus and one of the plurality of displays.
