Solution Overview

Problem

Current interactive display systems lack the ability to intuitively communicate which user is controlling the device in multi-user settings and do not provide efficient methods for users to relinquish or request control, leading to confusion and inefficient user interaction.

Innovation Solution

A multi-user interactive display system that uses a digital image capture system to analyze time sequences of images, designate a controlling user, and update content based on predefined gestures, with graphical elements indicating control status and priority order.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple users interact with the display system simultaneously, then user collaboration and productivity are improved, but confusion about control status and device complexity increase

Engineering Contradiction:
Improveuser collaboration efficiencyVSAvoidcontrol management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system continuously monitors user presence, control status, and gestures, then provides real-time visual feedback through graphical elements that indicate who has control and what actions are recognized. This closed-loop feedback mechanism resolves the contradiction by making the complex multi-user state transparent and manageable for all participants.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system uses color-coded graphical elements to differentiate control status - for example, highlighting the controlling user with distinct colors or patterns. This visual encoding simplifies the complex information about who controls what, allowing multiple users to efficiently understand system state without cognitive overload.

Inventive Principle:
Principle #32Color changes

2Loss of information

If the system provides detailed control status information, then user awareness and interaction quality are improved, but information overload and interface clutter increase

Engineering Contradiction:
Improvecontrol status communicationVSAvoiddisplay region usage
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

The display is segmented into functional regions - the information display region for content and the command control region for control interface. Graphical elements are strategically placed in the command control region, ensuring that control status information is communicated clearly without encroaching on or cluttering the primary information display area.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If gesture recognition is made more sophisticated, then control precision and user experience are improved, but processing time and computational load increase

Engineering Contradiction:
Improvegesture detection accuracyVSAvoidgesture processing delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary processing of gesture data by continuously analyzing the time sequence of images and pre-identifying potential gestures before full processing is required. This allows the system to maintain sophisticated gesture recognition capabilities while minimizing perceptible processing delays during actual interaction.

Inventive Principle:
Principle #10Preliminary action

AI summary

A multi-user interactive display system including a soft-copy display including at least an information display region and a command control region, and a digital image capture system positioned to capture a time sequence of images of users located in a field-of-view of the soft-copy display. A time sequence of images is analyzed to detect a plurality of users, and at least one of the users is designated to be a controlling user. The captured images are displayed in the command control region, wherein the detected users are demarked using graphical elements. The captured time sequence of images is analyzed to detect a gesture made by the controlling user and content displayed in the information display region is updated accordingly.
