Solution Overview

Problem

Existing gesture-based user operation technologies face challenges in accurately realizing user intentions due to vibrations affecting posture detection, leading to difficulties in executing intended functions.

Innovation Solution

An information processing apparatus and method that acquires driving information for controlling a driving device imparting movement to an object and identifies a dictated position based on detection information, adjusting for vibrations to ensure accurate user intent realization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vibration is imparted to the device to increase sense of realism, then user experience is improved, but posture detection accuracy deteriorates because the detected posture may be affected by the vibration

Engineering Contradiction:
Improveuser experienceVSAvoidposture detection accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent separates vibration detection from posture detection by using different sensors (acceleration sensor for vibration, posture sensor for posture). This segmentation allows independent processing of vibration signals and posture signals, preventing vibration noise from affecting posture detection accuracy while still providing haptic feedback to users.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary processing step where vibration detection results are used to correct or compensate for posture detection data. The vibration detection acts as a mediator that identifies when vibration occurs and adjusts the posture detection accordingly, maintaining accuracy despite vibration interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If gesture-based control is implemented for intuitive operation, then ease of operation is improved, but reliability of function execution deteriorates due to vibration interference with detection

Engineering Contradiction:
Improveintuitive operationVSAvoidfunction execution accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where vibration detection results are fed back into the gesture recognition system. When vibration is detected, the system adjusts its interpretation of posture changes, distinguishing between intentional gestures and vibration-induced movements. This feedback loop ensures that functions are executed reliably even during vibration periods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs preliminary vibration detection and characterization before processing gesture commands. By detecting and analyzing vibration patterns in advance, the system can preemptively adjust its gesture recognition thresholds or ignore detections that coincide with vibration events, ensuring reliable function execution.

Inventive Principle:
Principle #10Preliminary action
