Dynamic User Interface Control for Collaborative Large Screen Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems with large screens struggle to facilitate collaborative actions among multiple users, provide user-friendly manipulation regardless of user position or state, display objects in suitable sizes, and correctly show image contents from multiple sources simultaneously, especially when the screen is rotated.
Innovation Solution
An information processing apparatus that includes a control unit to adjust the user interface based on user position and state, using sensors to detect user input and optimize the display and input methods, ensuring correct size and position relationships of images, and rotating objects to face users appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large screen is used to display multiple objects in various orientations, then the display area is improved, but the ease of rotational manipulation deteriorates
Solution Approach 1:
The screen is divided into multiple independent manipulation regions, each associated with specific objects. Users can manipulate objects in different regions independently without rotating the entire screen, as each region can be individually oriented or accessed through localized interactions.
Solution Approach 2:
Instead of rotating the screen in the horizontal plane to change object orientation, the system introduces a virtual rotation dimension through software. Objects can be rotated visually within their regions while the screen itself remains stationary, adding a layer of virtual manipulation dimension.
2Reliability
If individual manipulation rights are assigned to each user for each object, then the reliability of object manipulation is improved, but the ease of collaborative action deteriorates
Solution Approach 1:
Manipulation rights are made dynamic rather than static. The system automatically adjusts which user has control over which objects based on real-time factors such as user position relative to the screen, current interaction state, and object importance. This allows seamless transitions of control between users without requiring manual rights management.
Solution Approach 2:
The system continuously monitors user positions, interaction patterns, and object states to provide feedback for automatic rights allocation. When a user approaches the screen or begins interacting with an object, the system detects these changes and adjusts manipulation rights accordingly, enabling intuitive collaborative behavior.
3Device complexity
If the GUI and input unit are kept constant, then the device complexity is reduced, but the adaptability to different user positions and states deteriorates
Solution Approach 1:
The GUI and input units are made dynamically adaptable based on detected user positions and states. The system automatically adjusts interface elements, their positions, sizes, and types of input accepted according to where users are located relative to the screen and what they are currently doing, all through automated detection and adjustment mechanisms.

AI summary
An information processing apparatus may include a control unit to control a user interface based on a determination of (i) a change in position of a user and (ii) a state of the user, by detecting at least one information signal input to the apparatus from outside of the apparatus.
