Adaptive Pointer Control for Remote Gesture Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face difficulties in moving a pointer accurately when the pointing part is far away from the device, as the remote pointing method is not efficient in such scenarios.
Innovation Solution
A display device equipped with a motion sensing unit that adjusts the pointer's movement based on the distance and angle between the pointing part and the device, allowing for varying motion intervals to facilitate easier control, regardless of the distance or angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote pointing method is used with a pointing part far away from the display device, then the user can operate the device from a distance, but the pointer movement becomes difficult and imprecise
Solution Approach 1:
The patent applies dynamics by making the pointer movement characteristics adjustable and adaptive rather than fixed. The controller dynamically modifies the pointer's movement speed, distance, or trajectory based on detected user gestures, pointing part position, or contextual information. This allows the system to optimize pointer control responsiveness for different operating conditions, thereby improving ease of operation while maintaining positioning accuracy even when the pointing part is far from the display device.
Solution Approach 2:
The patent employs parameter changes by modifying one or more parameters of the pointer movement (such as movement speed, movement distance, or response sensitivity) based on detected gestures or pointing part characteristics. When the pointing part is far away, the system adjusts these parameters to enhance control precision and ease of use, directly addressing the contradiction between operational ease and positioning accuracy at distance.
2Ease of operation
If the pointer movement is adjusted to be more responsive for distant pointing, then ease of operation improves, but control precision may deteriorate
Solution Approach 1:
The system dynamically adjusts pointer movement characteristics based on real-time detection of user gestures and pointing part position. When the pointing part is detected at a greater distance, the controller modifies the pointer's responsiveness and movement parameters adaptively, ensuring that increased responsiveness does not compromise placement accuracy. This dynamic adjustment resolves the contradiction by optimizing both ease of operation and precision simultaneously.
Solution Approach 2:
The patent implements feedback mechanisms where the controller continuously monitors user gestures and pointing part characteristics, then uses this information to adjust pointer movement parameters. This closed-loop feedback system ensures that the pointer responds appropriately to user input while maintaining accurate placement, even when the pointing part is far from the display device, thereby resolving the contradiction between responsiveness and precision.
Data Source
AI summary
A display device and a method for driving the same are disclosed. The display device includes a display unit configured to display a pointer and a controller configured to differently control a motion of the pointer corresponding to a moving distance of a pointing part depending on a distance from the pointing part inputting a gesture command.
