Solution Overview

Problem

Existing display devices face difficulties in accurately selecting small items using a conventional remote controller, particularly when items are displayed across a screen, as commercially available remote controllers are designed for air use and lack precise coordinate recognition for different modes.

Innovation Solution

A display device and method that utilize a remote controller with 6-axis gyro sensors to determine its mode, converting data into coordinate values based on whether it's used in a mouse mode or remote controller mode, adjusting user interfaces and cursor speeds accordingly to enhance selection accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a conventional remote controller is used for air use, then the device complexity is reduced, but the measurement precision of coordinate recognition deteriorates

Engineering Contradiction:
Improveremote controller structureVSAvoidcoordinate recognition accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent applies dynamics by enabling the remote controller to dynamically switch between two operational modes: air use mode and horizontal use mode. The controller automatically detects the usage scenario and adjusts its coordinate recognition algorithm accordingly, allowing it to function effectively in both orientations without requiring separate devices for each mode.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the coordinate recognition parameters based on the detected usage mode. When in horizontal use mode, the controller adjusts its sensitivity and coordinate mapping parameters to accurately recognize small item selections on the screen, whereas in air use mode, it uses parameters optimized for directional control and navigation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the remote controller supports both air and horizontal modes, then the adaptability improves, but the device complexity increases

Engineering Contradiction:
Improveusage mode flexibilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single remote controller that performs multiple functions across different usage scenarios. The same hardware device can be used for both air-based directional control and horizontal surface-based precision selection, eliminating the need for separate controllers for different modes and maximizing the utility of a single device.

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

3Measurement precision

If coordinate conversion based on mode is implemented, then the measurement precision improves, but the processing time increases

Engineering Contradiction:
Improveitem selection accuracyVSAvoidmode determination time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring multiple coordinate recognition algorithms corresponding to different usage modes. The system determines the appropriate mode in advance based on sensor input or user selection, and then applies the corresponding pre-prepared algorithm, avoiding the need for complex real-time calculations and reducing processing delays.

Inventive Principle:
Principle #10Preliminary action
