Touchscreen Graphic Composition Across Multiple Multimedia Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia systems lack a mechanism to differentiate and manage graphic objects from different sources across distinct software and hardware environments, limiting interaction capabilities with touch controls on a touch screen, especially in the automotive field where diverse multimedia sources with varying security levels require enhanced graphics management.
Innovation Solution
A method that combines graphic planes from multiple multimedia sources using a final composition unit, identifying the source of a manipulated object through transparency information and superposition order, allowing touch commands to be transmitted directly to the source for updating and managing graphic objects on a touch screen, independent of hardware and operating systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common graphic composition is implemented to display multiple multimedia sources on a single touch screen, then display integration and versatility are improved, but the ability to directly interact with graphic objects from different sources via touch commands deteriorates
Solution Approach 1:
The patent segments the graphic composition management by introducing a dedicated window manager component that separates the management of graphic objects from different multimedia sources. Each graphic object maintains its source identity while being displayed in a unified composition, allowing touch commands to be routed to the appropriate source through the window manager's object management mechanisms.
Solution Approach 2:
The window manager acts as an intermediary between the touch screen interface and multiple multimedia sources. It receives touch commands, identifies the target graphic object, determines the originating multimedia source, and routes the command appropriately. This mediator enables seamless interaction without requiring changes to the underlying heterogeneous sources.
2Reliability
If separate software and hardware environments are used for different multimedia sources, then functional security and system reliability are improved, but the complexity of managing graphic objects across these environments increases
Solution Approach 1:
The patent implements a universal window manager that can handle graphic objects from diverse multimedia sources regardless of their underlying software or hardware environment. The window manager provides a standardized interface for creating, managing, and interacting with graphic objects, enabling it to work with multiple sources having different security levels and technical characteristics through a single unified mechanism.
Solution Approach 2:
The window manager serves as an intermediary layer that abstracts the complexity of heterogeneous environments. It manages graphic objects from sources with different operating systems, security requirements, and technical specifications without requiring each source to implement complex cross-environment compatibility mechanisms.
3Manufacturing precision
If dedicated control modules are used for each screen display management, then display control precision is improved, but the bandwidth usage for transmitting graphic content increases
Solution Approach 1:
The patent extracts the essential graphic object management functions from the dedicated control modules and consolidates them in the window manager. Instead of each control module independently managing all aspects of graphic composition and interaction, the window manager handles object creation, positioning, and command routing, allowing control modules to focus on display rendering with reduced data transmission requirements.

AI summary
The invention relates to a method for simultaneously managing a plurality of graphic objects that can be manipulated (O#1-O#7) coming from multiple multimedia sources (1-3), each of the objects being displayed individually according to a common graphic composition (12) on a touchscreen (20), which involves providing a final composition unit (10) with the content of a plurality of source image memories (11, 21, 31), each storing a graphic plan of at least one graphic object created by a respective multimedia source, said graphic plan comprising colour and transparency information of said graphic object for each pixel of said touchscreen, receiving a touch command in order to manipulate a displayed graphic object, identifying the source of said manipulated object from the transparency information provided by said graphic plans, updating the source image memory of the identified source as a function of said touch command received, and producing a new common graphic composition.
