Data-Collecting Play Object Sensor Fusion for Skill Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent gaming objects currently collect insufficient data to accurately assess a player's skills, often focusing on specific skills while neglecting others, and sampling rates are too low, leading to lower quality measurements and incorrect conclusions about skill levels.
Innovation Solution
A play object equipped with a data-collecting unit containing an accelerometer and gyroscope that measures acceleration and rotation values, transmitted wirelessly at discrete intervals, along with a processor and power source, allowing for comprehensive data collection and analysis of player performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gaming object collects information about a specific skill, then that specific skill can be assessed, but other skills or related skills cannot be assessed
Solution Approach 1:
The gaming object is designed with multiple sensors (accelerometer, gyroscope, and optionally magnetometer) that can measure various physical quantities. This multi-functional sensor array enables the single device to assess multiple different skills simultaneously, transforming a specialized single-skill assessment tool into a universal multi-skill assessment system
2Measurement precision
If a gaming object samples information at a low rate, then the device complexity is reduced, but the measurement quality decreases leading to incorrect conclusions about player skill level
Solution Approach 1:
The system changes the sampling rate parameter to a high value, enabling capture of rapid movements and transient events during gameplay. This high-rate sampling transforms low-quality measurements into high-resolution data that accurately reflects player skills, with the processor and memory components managing the increased data volume

Implementation Method 2
a gyroscope unit measuring rotation values of the play object about at least one rotational degree of freedom
Data Source
AI summary
A data-collecting play object. The play object includes a body manipulated by a player. A data-collecting unit is disposed in the interior of the body. The data-collecting unit includes an accelerometer unit measuring acceleration values along at least one translational degree of freedom, a gyroscope unit measuring rotation values about at least one rotational degree of freedom, and a processor in communication with the accelerometer unit and with the gyroscope unit.
