Hovering Input Detection for Intuitive IoT Object Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of IoT environments, there is a demand for technologies that allow users to control devices through various types of inputs to access multiple services, as existing methods are limited in their ability to detect and respond to non-contact hovering inputs effectively.
Innovation Solution
A method where a device detects a hovering inputter, determines a target object based on location information, and performs a predetermined operation on that object, allowing for intuitive control without physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device uses traditional touch input methods, then the control mechanism is simple and reliable, but the user experience lacks intuitiveness and versatility for IoT applications
Solution Approach 1:
The patent replaces traditional mechanical touch contact with a hovering input detection system using sensors (such as capacitive, electromagnetic, or optical sensors) to detect the presence and position of an inputter without physical contact. This substitution enables more intuitive and versatile control while maintaining reliability through multiple detection modes.
Solution Approach 2:
The patent introduces an intermediary hovering detection mechanism between the user and the device interface. The sensor system acts as an intermediary that detects the hovering inputter's position and translates it into control signals, enabling versatile control without direct mechanical contact and enhancing user experience through natural gestures.
2Adaptability or versatility
If a device implements hovering input detection, then the control versatility and intuitiveness are improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal hovering detection system that can detect multiple types of inputters (fingers, styluses, other devices) using the same sensor array. The system performs multiple functions including position detection, gesture recognition, and target object identification, thereby achieving high versatility without proportionally increasing complexity through shared hardware resources and integrated processing.
Solution Approach 2:
The patent utilizes parameter changes in the sensor output (such as capacitance variation, electromagnetic field strength, or optical reflection patterns) to detect different hovering inputters and gestures. By monitoring and interpreting these parameter changes, the system achieves versatile input detection capability while maintaining relatively simple hardware through software-based differentiation of detection signals.
3Measurement precision
If a device determines target objects based on hovering location, then the precision of object selection is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent segments the detection area into multiple zones corresponding to different displayed objects. Each zone is associated with specific target objects, and the system determines the hovering inputter's position relative to these segmented zones to identify the target object with high precision. This segmentation approach simplifies the detection process by mapping spatial position to object selection.
Solution Approach 2:
The patent implements a feedback mechanism where the device provides visual or haptic feedback to confirm target object selection based on hovering position. The system continuously monitors the hovering inputter's location and updates the target object selection in real-time, providing feedback to the user about which object will be activated. This feedback loop enhances measurement precision by allowing continuous adjustment and confirmation of the intended target.
