Multi-view Display Capacitive Sensing for User Interaction Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-view display systems face inefficiencies in user interaction and content relevance when multiple users are present, as they often present the same content to all users and can become cluttered with complex interfaces, limiting individual user experiences.
Innovation Solution
A multi-view display system utilizing a touch-screen panel with capacitive sensing and motion tracking to differentiate user interactions based on capacitive signals and viewing angles, allowing each user to interact with personalized content and interface elements, even when overlapping in physical space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single display presents content to multiple users simultaneously, then the display can serve multiple users at once, but the content relevance and communication efficiency decrease for each individual user
Solution Approach 1:
The display surface is segmented into multiple independent display regions, each dedicated to a specific user. The system divides the unified display area into separate zones based on detected user positions, allowing each user to view personalized content in their own region while sharing the same physical display device.
Solution Approach 2:
Different regions of the display are assigned different content and interface characteristics tailored to each user's needs and viewing angle. Each local region provides customized information and controls appropriate for that specific user, rather than presenting uniform content across the entire display.
2Adaptability or versatility
If a multi-user interface includes all elements each user uses, then all users can access their functions, but the interface becomes cluttered and complex
Solution Approach 1:
The user interface is segmented into separate interface regions corresponding to each user. Each user's interface elements, controls, and menus are confined to their designated display region, preventing visual clutter while maintaining full multi-user functionality. Users can access all necessary functions within their own organized space without being overwhelmed by other users' interface elements.
3Device complexity
If the display presents the same content to all users, then the interface remains simple and unified, but the communication efficiency and user experience are limited
Solution Approach 1:
The display system dynamically adjusts content presentation based on real-time detection of user positions, viewing angles, and interaction patterns. The interface automatically reconfigures which users see which content and controls, allowing the system to transition between unified and personalized modes as needed to optimize communication efficiency.

AI summary
In one embodiment, a method includes generating, at a multi-view display, a first content to be viewed at a first angle and a second content to be viewed at a second angle. The first content and the second content are displayed simultaneously. The method also includes receiving, at a touch-screen panel coupled to the multi-view display, a first plurality of capacitive signals. The method then generates, by the touch-screen panel, a first touch-screen panel heatmap based on the received first plurality of capacitive signals. The method afterwards determines, based on the first touch-screen panel heatmap, whether a first user input is received with respect to the first content or the second content. The method then assigns, based on determining the first user input corresponds to either the first content or the second content, the first user input to the first content or the second content.
