Adaptive Sensing Resolution for Object Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object navigating apparatuses with fixed sensing resolution are inconvenient for users, as they fail to accurately differentiate between cursor movement and click operations, especially when the user needs to adjust sensitivity based on displacement speed and frequency.
Innovation Solution
An object navigating apparatus that adjusts sensing resolution based on the value and frequency of object displacement, increasing resolution for large and frequent displacements and decreasing it for small and infrequent ones, allowing for adaptive sensitivity adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the sensing resolution is increased to enable fast cursor movement with slight finger displacement, then the cursor displacement speed is improved, but the accuracy for determining click operations deteriorates
Solution Approach 1:
The sensing resolution is made dynamically adjustable rather than fixed. The control unit changes the sensing resolution based on real-time detection of displacement patterns, transitioning between high resolution mode (for fast movements) and low resolution mode (for precise operations), thereby resolving the contradiction between speed and precision
Solution Approach 2:
The sensing resolution parameter is changed adaptively based on detected displacement characteristics. When large displacements are detected, the resolution is increased to enable fast cursor movement; when small displacements are detected, the resolution is decreased to improve click operation accuracy, thus resolving the technical contradiction
2Adaptability or versatility
If the sensing resolution is adjusted based on average moving speed in past time, then the sensitivity adaptation is improved, but the response time for sudden fast movements deteriorates
Solution Approach 1:
The system performs preliminary detection of displacement patterns continuously and adjusts the sensing resolution in advance before sudden fast movements occur. By monitoring displacement characteristics in real-time and pre-adjusting the resolution based on detected patterns, the system reduces response time delays
Solution Approach 2:
The control unit continuously monitors displacement data and uses feedback to dynamically adjust the sensing resolution. When displacement patterns indicate upcoming fast movement, the system preemptively increases resolution, thereby reducing response time while maintaining adaptability

AI summary
An object navigating apparatus, which comprises: a sensing apparatus, for sensing an object; and a control unit, for computing at least one displacement that the object is relative to the sensing apparatus. The control unit increases the sensing resolution if the control unit detects the displacement is larger than a first predetermined value for continuous N times, or if the control unit detects the displacement is larger than the first predetermined time for at least N times in a first sensing time interval. The N is a positive integer larger or equals to 2.
