Solution Overview

Problem

Current multi-touch display panels lack the ability to enable concurrent, remote control and interaction with multiple devices by multiple users, limiting collaborative user experiences.

Innovation Solution

A multi-touch display panel system that connects to remote devices, displays sub-display surfaces, and sends touch events to these devices, allowing users to interact with and control multiple devices simultaneously through a large, shared touch interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multi-touch display panel is used for single-device control, then touch interaction capability is improved, but concurrent control of multiple remote devices is not enabled

Engineering Contradiction:
Improveconcurrent control capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display panel is divided into multiple independent sub-display surfaces, each corresponding to a different remote device. Each sub-display surface can be independently controlled and interacted with, allowing multiple users to simultaneously control different devices without interference. The segmentation enables the system to handle multiple device control tasks concurrently while maintaining individual device functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multi-touch display panel is designed to serve multiple functions: it can display content from multiple remote devices simultaneously, receive touch inputs for different devices, and route controls to the appropriate target device. This multi-functional design allows a single hardware platform to support concurrent control of multiple devices with different characteristics and interfaces.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple sub-display surfaces are displayed concurrently, then user interaction with multiple devices is enabled, but processing complexity increases

Engineering Contradiction:
Improveconcurrent interaction efficiencyVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A controller acts as an intermediary between the multi-touch display panel and multiple remote devices. The controller receives touch events from the display panel, determines which sub-display surface was touched, and routes the control signal to the corresponding remote device. This intermediary architecture simplifies the overall system by centralizing the complex routing and coordination logic in a single component.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system adds a spatial dimension to device control by arranging multiple sub-display surfaces in a two-dimensional layout on the display panel. Each sub-display surface occupies a specific region, and touch events are processed based on their spatial location. This dimensional approach allows intuitive simultaneous access to multiple devices without increasing processing complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If touch events are routed to corresponding remote devices, then precise device control is achieved, but event routing complexity increases

Engineering Contradiction:
Improvetouch event accuracyVSAvoidrouting complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The display panel is segmented into distinct sub-display surfaces, each with a defined spatial region corresponding to a specific remote device. Touch events are accurately routed by determining which sub-display surface region was contacted. This segmentation provides a natural and intuitive method for precise event routing without requiring complex routing logic.

Inventive Principle:
Principle #1Segmentation
