Confined Sensor Input Region for Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor input systems face issues with unwanted input in certain locations of the sensing area, such as accidental user input from bystanders in motion sensor applications, which can disrupt intended interactions.
Innovation Solution
An apparatus and method that establish a confined input region within the total sensing area by recognizing control gestures, allowing users to define the boundaries of this region, and translate gestures sensed within this area into input events while ignoring those outside it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sensing area is made large to capture more user input, then the coverage and usability are improved, but unwanted input from bystanders or unintended areas increases
Solution Approach 1:
The sensing area is divided into multiple distinct input regions, each associated with specific input devices or functions. This segmentation allows the system to process input differently based on location, enabling large coverage while filtering unwanted input by restricting which regions accept input for specific devices.
Solution Approach 2:
Different regions within the sensing area are assigned different qualities or characteristics. Each input region has specific properties that determine which input devices can interact with it and how input is processed, allowing the system to optimize each region for its intended purpose while reducing interference from other areas.
2Reliability
If the sensing area is restricted to reduce unwanted input, then the accuracy and reliability are improved, but the coverage and usability deteriorate
Solution Approach 1:
The input regions are configured dynamically based on detected user presence and device locations. The system can adjust the boundaries and properties of input regions in real-time, expanding them when users are present and contracting or deactivating them when no users are detected, thus maintaining reliability while maximizing coverage when needed.
Solution Approach 2:
The system continuously monitors the sensing area for user presence and input patterns, using this feedback to adjust the configuration of input regions. This feedback mechanism allows the system to maintain high input accuracy by adapting region boundaries and properties based on actual usage conditions and user behavior patterns.
3Adaptability or versatility
If multiple input devices share the same sensing area, then the versatility and functionality are improved, but input conflicts and interference increase
Solution Approach 1:
The sensing area is segmented into multiple input regions, with each region dedicated to specific input devices or functions. This spatial segmentation allows multiple devices to operate simultaneously without interference, as each device interacts only with its designated region while other regions remain exclusive to their respective devices.
Solution Approach 2:
Each input region is configured with specific local qualities that determine which input devices can interact with it. By assigning different properties to different regions, the system enables versatile multi-device support while preventing interference, as each device operates within its own optimized zone with controlled access rules.
