Solution Overview

Problem

Touch-screen displays often require users to manually adjust the orientation of elements to align with their perspective, which can be inconvenient and hinder interaction efficiency, especially when users are in different positions relative to the display.

Innovation Solution

Implementing a system with cameras to capture images of users and automatically adjust the orientation of displayed elements based on the user's position and interaction with the touch-screen display, ensuring that elements are aligned correctly within the user's field of view without requiring explicit user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of element orientation is required, then device complexity is reduced, but ease of operation deteriorates

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically detects user position and orientation using camera-based image processing, and autonomously adjusts element orientation without requiring manual user input. The system serves itself by interpreting visual data and making orientation adjustments independently, eliminating the need for users to manually rotate or reposition displayed elements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated vision-based system. Instead of requiring users to physically interact with controls to change orientation, the system uses image capture and processing to detect user position, then automatically computes and applies the appropriate orientation transformation, substituting mechanical user action with optical detection and computational adjustment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If automatic orientation adjustment is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The camera system serves multiple functions: it captures user position data for orientation adjustment, detects user presence, and potentially tracks user movement. By making the camera a multi-functional component, the patent reduces the need for separate sensors and processing systems, thereby limiting the increase in overall device complexity while achieving automatic orientation adjustment.

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

Solution Approach 2:

The system introduces an intermediary processing layer that translates raw image data into orientation parameters. Rather than directly controlling display orientation from multiple independent sensors, the image processing system acts as a mediator that consolidates user position information and computes the appropriate orientation transformation, simplifying the control architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If user position detection is added, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary detection of user position and orientation before the user interacts with the display. By capturing images and determining user orientation in advance, the system can pre-compute the appropriate element orientation, ensuring that elements are correctly aligned when the user begins interaction, thereby improving adaptability without adding complex real-time adjustment mechanisms.

Inventive Principle:
Principle #10Preliminary action

AI summary

An element is initially displayed on an interactive touch-screen display device with an initial orientation relative to the interactive touch-screen display device. One or more images of a user of the interactive touch-screen display device are captured. The user is determined to be interacting with the element displayed on the interactive touch-screen display device. In addition, an orientation of the user relative to the interactive touch-screen display device is determined based on at least one captured image of the user of the interactive touch-screen display device. Thereafter, in response to determining that the user is interacting with the displayed element, the initial orientation of the displayed element relative to the interactive touch-screen display device is automatically adjusted based on the determined orientation of the user relative to the interactive touch-screen display device.
