Spatial Gesture Multi-User Shared Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display devices, such as computer monitors and televisions, are typically controlled by a single user, limiting shared experiences among multiple users, who may have different preferences for web browsing or television viewing.
Innovation Solution
A spatial-input-based multi-user shared display system that detects user gestures within a physical user space to enable concurrent control of display resources, allowing multiple users to share control of a display screen through a shared display heuristic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional display devices are controlled by a single user, then control simplicity is maintained, but user engagement and collaborative experience deteriorate
Solution Approach 1:
The display screen is divided into multiple zones, with each zone assignable to different users. This allows multiple users to simultaneously control different portions of the display without interfering with each other, thereby improving user engagement while maintaining relatively simple control mechanisms.
Solution Approach 2:
The patent introduces spatial dimension to user control by detecting hand gestures at different positions in front of the display. Users can control the display by making gestures in their designated zone, adding a spatial dimension to the control mechanism that enables multi-user support without significantly increasing complexity.
2Adaptability or versatility
If display control is shared among multiple users, then collaborative experience is improved, but control conflict and resource management complexity worsen
Solution Approach 1:
Different regions or zones of the display are assigned to different users, allowing each user to have exclusive control over their designated area. This local quality approach enables collaborative multi-user experience while simplifying resource management by avoiding conflicts through spatial separation.
Solution Approach 2:
The system introduces a zone assignment mechanism that acts as an intermediary between multiple users and the display resources. This mediator automatically manages resource allocation based on user identity and assigned zones, reducing the complexity of direct user-resource conflict management.
3Adaptability or versatility
If spatial gesture recognition is implemented, then multi-user control capability is improved, but system complexity and processing requirements worsen
Solution Approach 1:
The patent replaces traditional mechanical input devices (mouse, keyboard, remote control) with gesture recognition technology. This substitution enables natural, contactless control through hand gestures detected by cameras or sensors, improving multi-user control capability while the complexity is managed through software-based gesture recognition rather than additional hardware.

AI summary
An exemplary system includes a spatial input subsystem configured to detect gestures made by a plurality of users within a physical user space associated with a display screen. The system further includes a shared display subsystem communicatively coupled to the spatial input subsystem and configured to authenticate the plurality of users by identifying a plurality of user identities corresponding to the plurality of users based on characteristics of the plurality of hands, and execute a multi-user shared display session that provides the plurality of authenticated users with concurrent control of a display on the display screen. Corresponding systems and methods are also described.
