Solution Overview

Problem

Existing piano training methods fail to effectively improve individual pianists' force sense skills, as training is not tailored to address personal differences in force perception.

Innovation Solution

An information processing device and method that controls load weights on a keyboard to simulate varying forces, allowing pianists to discriminate and evaluate force senses through recognition and feedback, thereby improving their force sense and overall performance skills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional piano training methods are used, then general playing skills are developed, but individual force sense discrimination abilities are not improved

Engineering Contradiction:
Improveforce sense discrimination abilityVSAvoidindividual differences in force sense
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system provides localized force sense training by applying specific load weights to individual keys that the user depresses. Each key can have a customized load weight applied, allowing targeted improvement of force discrimination ability at specific locations rather than general training.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the parameter of load weight applied to keys to create different training conditions. By varying the load weight magnitude and applying it selectively based on user input, the system adapts to individual force sense characteristics and provides personalized training to improve discrimination ability.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If load weight is applied to simulate varying forces, then force sense discrimination training is enabled, but device complexity increases

Engineering Contradiction:
Improveforce sense discrimination abilityVSAvoidload weight control system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The load weight control unit serves multiple functions: it generates load weights, controls their application timing, and coordinates with the recognition unit. This multi-functionality reduces the need for separate components and simplifies the overall device structure while enabling force sense discrimination training.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the user's own depression actions as input signals to trigger load weight generation. The recognition unit detects when a key is depressed and automatically activates the appropriate load weight, creating a self-service mechanism where the user's natural interaction drives the training process without requiring complex external control.

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure relates to an information processing device, an information processing method, and a program that further improve skills. A load weight control unit controls generation of a load weight that becomes a load with respect to motion when a keyboard is depressed by a pianist, and a keystroke recognition unit recognizes motion of the keyboard. Then, the load weight control unit performs control of starting generation of a predetermined load weight at a timing when the keystroke recognition unit recognizes that the keyboard started to be depressed, and ending generation of the load weight at a timing when the keystroke recognition unit recognizes that the keyboard ended to be depressed and started to return. The present technology can be applied to, for example, a performance skill improvement system that evaluates and trains pianists' force sense.
