3D Content Scrolling via Acceleration Pattern Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively differentiate between intentional and unintentional movements of a device within three-dimensional content rendering systems, leading to unwanted scrolling during vehicle travel or other incidental movements.
Innovation Solution
An apparatus and method that determine movement by comparing expected and measured accelerations, categorizing movements into intentional (first category) and unintentional (second category) to control scrolling accordingly, ensuring that only intended user actions trigger changes in the three-dimensional content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the three dimensional content is scrolled to correspond to all detected movements of the apparatus, then the user can navigate through the content by moving the device, but unwanted scrolling occurs during vehicle travel or incidental movements
Solution Approach 1:
The system uses acceleration sensors to detect movement and provides feedback by comparing expected accelerations (based on determined path) with measured accelerations. This feedback loop enables the system to distinguish between intentional user movements and incidental movements during vehicle travel, scrolling content only when the movements match user intent patterns.
Solution Approach 2:
The system changes the parameter of movement classification by categorizing movements into different types (intentional vs. incidental) based on acceleration patterns. By analyzing the characteristics of acceleration vectors and comparing them against expected patterns for the determined path, the system dynamically adjusts which movements trigger scrolling, resolving the contradiction between ease of navigation and scrolling accuracy.
2Speed
If the apparatus continuously monitors and responds to all movements, then responsive content interaction is achieved, but false triggering during incidental movements occurs
Solution Approach 1:
The system introduces an intermediary classification layer between movement detection and content scrolling. The acceleration data from sensors is processed through a classification mechanism that determines whether the movement is intentional or incidental based on expected acceleration patterns. This intermediary step prevents false triggering while maintaining rapid response to genuine user actions.
Solution Approach 2:
The system replaces simple mechanical movement-triggered scrolling with a more sophisticated sensor-based acceleration analysis system. By using acceleration sensors and comparing measured accelerations against expected patterns, the system achieves more precise movement intent detection while maintaining fast response times, eliminating false triggers during incidental movements.
3Reliability
If the system differentiates between intentional and unintentional movements, then unwanted scrolling is prevented, but the device complexity increases
Solution Approach 1:
The system uses the device's own existing acceleration sensors and path determination capabilities to classify movements, rather than requiring external complex hardware. The apparatus leverages its inherent sensing abilities to distinguish between intentional and unintentional movements, achieving reliable scrolling control without significantly increasing device complexity.
Solution Approach 2:
The movement classification system serves multiple functions: it enables reliable scrolling control, provides the basis for path determination, and utilizes existing acceleration sensing capabilities. By making the classification system multi-functional and integrating it with existing device capabilities, the patent achieves reliable scrolling control without proportionally increasing device complexity.
