Solution Overview

Problem

Existing multi-focal plane displays (MLDs) face limitations in user interaction, particularly in enhancing preattentive processing and providing ergonomic and intuitive user interfaces, with techniques like head-mounted displays causing discomfort and lenticular displays being angle-dependent.

Innovation Solution

A display system with multiple LCD layers and a proximity sensor dynamically updates visual content based on user proximity, moving user interface elements between layers to emphasize interaction and simplify the interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple display layers are used to enhance preattentive processing and depth perception, then information processing speed and depth capability are improved, but interface complexity and user interaction difficulty increase

Engineering Contradiction:
Improveinformation processing speedVSAvoidinterface complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The display interface is segmented into multiple layers (first display layer and second display layer) that can be independently controlled. Preattentive processing elements are placed on the second layer while primary user interface elements remain on the first layer, allowing parallel information processing without increasing perceived complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a depth dimension by stacking multiple display layers vertically. This allows information to be organized in three-dimensional space rather than two dimensions, enabling preattentive processing of background elements while keeping foreground interface elements accessible, thus improving productivity without sacrificing usability.

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

2Productivity

If depth effects are added to enhance visual information processing, then preattentive processing capability is improved, but ease of operation decreases due to increased interface complexity

Engineering Contradiction:
Improvepreattentive processing capabilityVSAvoidease of operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Different display layers have different functional qualities: the first layer is optimized for user interaction with primary interface elements, while the second layer is optimized for preattentive processing of supplementary information. This local differentiation allows each layer to excel at its specific function without compromising the other.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The controller acts as an intermediary that manages the interaction between multiple display layers and the user. It automatically coordinates which elements appear on which layer based on user proximity and interaction state, eliminating the need for users to manually manage layer complexity while preserving preattentive processing benefits.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If static interface elements are displayed on all layers, then information completeness is maintained, but user interaction becomes cluttered and less intuitive

Engineering Contradiction:
Improveinformation completenessVSAvoiduser interaction clarity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display system dynamically adjusts which interface elements appear on which layer based on user proximity detected by the proximity sensor. When a user approaches, primary interactive elements move to the first layer while supplementary information remains on the second layer. This dynamic reorganization maintains information completeness while ensuring interaction clarity at any given moment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system prepares the display state in advance by pre-positioning elements on appropriate layers based on anticipated user needs. The proximity sensor detects user approach and triggers preliminary reorganization of interface elements before actual interaction occurs, ensuring the interface is already optimized for the upcoming interaction.

Inventive Principle:
Principle #10Preliminary action

AI summary

Certain example embodiments relate to a system including a user-interactive display device having LCDs in substantially parallel spaced apart relation to one another. A proximity sensor is located proximate to the user-interactive display device. A controller is configured to perform instructions to perform functionality including: generating visual content, including one or more user interface elements (e.g., user-interactive elements), for output to the user-interactive display device; causing the user-interactive display device to display the generated visual content; receiving output from the proximity sensor; determining when an object of interest comes into proximity to the user-interactive display device, based on the received output from the proximity sensor; and responsive to a determination that the object of interest has come into proximity to the user-interactive display device, updating the generated visual content and causing the updated generated visual content to be displayed via the user-interactive display device.
