Practice Time Calculator Using Operation History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional practice time calculating methods for improving musical playing technique are inaccurate due to variable progress rates and degree of difficulty in practice pieces, leading to inconsistent and unreliable estimates of the time required to reach a target level.
Innovation Solution
A practice time calculating apparatus that evaluates the progressing level of a user's technique, records operation history, and calculates practice time based on both recent and accumulated progress rates, using a combination of performance and note-number history data to provide a more precise estimate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the remaining practice time is calculated based on the progressing level in the recent time, then the calculation reflects the latest skill improvement, but a large variation is caused in the calculated practice time due to the degree of difficulty of the practice piece that the user plays
Solution Approach 1:
The patent changes the parameters used in calculation from only progressing level to a combination of progressing level and operation number. By introducing operation number as an additional parameter and establishing a relationship between operation number and progressing level, the system adjusts the progressing level based on the difficulty of practice pieces, thereby reducing calculation variation while maintaining accuracy.
2Reliability
If the progressing rate of playing technique is not constant and suddenly increases, then the user shows rapid improvement, but the recent progressing level is not affected on the calculation of the remaining practice time, resulting in the calculated remaining practice time being longer than actually required
Solution Approach 1:
The patent implements feedback by continuously monitoring the relationship between operation numbers and progressing levels. When the progressing level increases more than expected relative to the operation number, the system detects this as accelerated improvement and adjusts the remaining practice time calculation accordingly, preventing overestimation of required practice time.
3Device complexity
If conventional techniques calculate practice time based only on progressing level history, then the calculation is simple, but the calculated practice time varies significantly due to variations in practice piece difficulty
Solution Approach 1:
The patent performs preliminary action by pre-establishing the relationship between operation numbers and progressing levels before calculating remaining practice time. The system accumulates operation number data and progresses level data in advance, and uses this pre-collected information to adjust the calculation, thereby improving accuracy without significantly increasing computational complexity.
Data Source
AI summary
An apparatus is provided, for calculating a practice time. The apparatus is used by a user to calculate such practice time that he/she requires to improve his/her playing technique to reach a predetermined progressing level at the playing technique. In the apparatus, a progressing-level evaluating unit evaluates a progressing level of a playing technique of the user who operates a playable unit. A history of the evaluated progressing level is recorded in a progressing-level recording unit. An operation-number counting unit counts the number of operations executed on the playable unit by the user every unit time. A history of the counted number of operations is recorded in an operation-number recording unit. A practice-time calculating unit calculates the practice time based on the history of the progressing level recorded in the progressing-level recording unit and the history of the number of operations recorded in the operation-number recording unit.
