Practice support device and practice support method for wind instrument performer

A device that supports a performer of a wind instrument, the device comprising:

• a processor;
• and
• a memory,
• wherein the processor acquires an image including a facial image of the performer, from a camera that captures images of the performer,
• the memory stores a table including a listing of conditions for a muscle length and a corresponding listing of support information for playing the wind instrument, and
• the processor
• determines a muscle length of a target muscle included in the facial image based on positions of a plurality of feature points in the facial image,
• determines whether the determined muscle length satisfies at least a portion of a target condition included in the listing of conditions,
• determines support information corresponding to the target condition,
• when the determined muscle length is determined to satisfy the at least a portion of the target condition, generates a support image corresponding to the determined support information, and
• controls a display to display the generated support image.

A method for supporting a performer of a wind instrument, the method including:

• acquiring, by a processor of a computing device, data indicating a myoelectric potential value measured by a myoelectric sensor arranged on a surface of a face of the performer;
• acquiring, from a microphone via the processor, sound of the wind instrument captured by the microphone;
• with reference to a table in which a listing of conditions for the myoelectric potential value and a corresponding listing of support information for playing the wind instrument, determining, by the processor, whether the acquired myoelectric potential value satisfies at least a portion of a target condition included in the listing of conditions, and determining, by the processor, whether the acquired sound of the wind instrument satisfies another portion of the target condition;
• determining, by the processor, support information corresponding to the target condition,
• when the acquired myoelectric potential value is determined to satisfy the at least a portion of the target condition and when the acquired sound of the wind instrument is determined to satisfy the other portion of the target condition, generating, by the processor, a support image corresponding to the determined support information;
• and
• displaying the generated support image on a display.
