Pointer Position Correction Using Frequency Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display devices face challenges in accurately performing user-intended operations due to issues with pointing devices, such as hand shaking and precision, leading to incorrect selections.
Innovation Solution
The method involves receiving a pointing signal and a selection signal from a pointing device, displaying a pointer, and performing an operation corresponding to the region where the pointer was most frequently displayed during an input standby time, ensuring accurate user intent is executed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pointing device is used to operate the image display device, then the device can perform various operations, but hand shaking and precision issues cause incorrect selections
Solution Approach 1:
The system records the pointer's position history during the input standby time before the selection signal is received. By analyzing the most frequently displayed region from this historical data, the system prepares the correct operation in advance, compensating for hand shaking that occurs during the pointing action.
Solution Approach 2:
The system provides feedback by analyzing the pointer's movement pattern and determining the most frequently displayed region. This feedback mechanism allows the system to understand the user's intended target despite hand shaking, and automatically corrects the selection based on this analysis.
2Productivity
If the pointer position is determined at the moment of selection signal, then the operation is executed quickly, but hand shaking causes selection of wrong region
Solution Approach 1:
The system performs the analysis of the most frequently displayed region during the input standby time, which is the period before the selection signal is received. This preliminary analysis ensures that the correct operation is identified in advance, maintaining both speed and accuracy.
Solution Approach 2:
The system dynamically determines the target region based on the pointer's movement pattern during the input standby time. Instead of using a fixed timing method, the system adapts to the user's pointing behavior by analyzing which region the pointer displayed most frequently, making the selection process both fast and reliable.
3Measurement precision
If the input standby time is extended to improve accuracy, then the pointer position can be determined more accurately, but the operation response time increases
Solution Approach 1:
The system uses a partial approach by analyzing only the most frequently displayed region during the input standby time, rather than considering all possible factors. This partial analysis method achieves sufficient accuracy without requiring an excessively long standby time, thus balancing precision and response time.

AI summary
According to an embodiment of the present invention, a method for operating an image display device that receives a signal from a pointing device includes receiving, from the pointing device, a pointing signal to display a pointer on a display of the image display device, and a selection signal, wherein the selection signal includes information regarding a command to perform an operation on the image display device, displaying, on the display, the pointer corresponding to the pointing signal, determining whether the pointer is displayed on a most frequently displayed region during an input standby time associated with the selection signal, and performing an operation associated the most frequently displayed region when the pointer is displayed on the most frequently displayed region during the input standby time.
