Solution Overview
Problem
Existing information processing devices face challenges in accurately determining the holding state of an operating device due to individual differences in devices and sensors, leading to inconsistent output values and noise signals that affect user operability.
Innovation Solution
The implementation of an information processing device with output value acquiring means, reference value acquiring means, and state value calculation means to correct output values based on predetermined reference values, combined with filtering processes tailored to specific application requirements to enhance accuracy and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If consistent filtering is applied to all state values, then noise signals are filtered out, but user operability deteriorates due to loss of required sensitivity in certain situations
Solution Approach 1:
The patent applies dynamic filtering by adjusting filtering parameters based on the current application context and operation type. The system switches between different filtering intensities - stronger filtering for applications requiring stability and weaker filtering for applications requiring sensitivity - thereby resolving the contradiction between noise filtering and user operability.
2Measurement precision
If output values from sensors are used directly, then individual device differences cause inconsistent state values, but calibration processes increase device complexity
Solution Approach 1:
The patent addresses individual device differences by adjusting calibration parameters for each device based on reference measurements. The system stores and applies device-specific correction parameters that compensate for sensor variations without requiring complex hardware modifications, thereby achieving consistent state values while minimizing added complexity.
3Adaptability or versatility
If multiple parameter sets are stored for different applications, then filtering can be optimized for each application, but device complexity increases
Solution Approach 1:
The patent prepares multiple parameter sets in advance for different application types and stores them in a lookup table or configuration database. When an application is launched, the system automatically selects the appropriate pre-configured parameter set based on the application identifier, enabling application-specific optimization without requiring complex real-time parameter adjustment logic.

AI summary
An information processing device acquires an output value in accordance with a state in which an operating device is held, acquires the output value in accordance with a predetermined first holding state of the operating device as a first reference value, acquires the output value in accordance with a predetermined second holding state of the operating device, different from the first holding state, as a second reference value, and calculates a state value indicative of the state in which the operating device is held, which is in accordance with the acquired output value, based on the first reference value and the second reference value.
