Information processing method and information processing apparatus

An information processing apparatus comprising:

• at least one processor configured to:
• obtain first position information that indicates a position of at least one of a ceiling surface, a wall surface, or a floor surface in a predetermined space;
• obtain second position information that indicates a position of an acoustic device that outputs a sound beam in the predetermined space;
• obtain direction information that indicates a direction of the sound beam to be outputted from the acoustic device;
• calculate a locus of the sound beam to be outputted from the acoustic device, based on the first position information, the second position information, and the direction information that have been obtained;
• generate a sound beam image that shows the locus of the sound beam, based on a result of calculation;
• obtain characteristic information that indicates a degree of sound absorption of the at least one of the ceiling surface, the wall surface, or the floor surface;
• and
• vary a visual display of a reflection image showing a reflection of the sound beam reflecting off of at least one of the ceiling surface, the wall surface, or the floor surface, based on the degree of the sound absorption.

An information processing method comprising:

• obtaining first position information that indicates a position of at least one of a ceiling surface, a wall surface, or a floor surface in a predetermined real space;
• obtaining second position information that indicates a position of an acoustic device that outputs a sound beam in the predetermined real space;
• obtaining direction information that indicates a direction in a three-dimensional rectangular coordinate system of the sound beam to be outputted from the acoustic device;
• calculating a locus of the sound beam to be outputted from the acoustic device and a locus of a reflected sound beam reflected off of the at least one of the ceiling surface, the wall surface, or the floor surface, based on the first position information, the second position information, and the direction information that have been obtained, wherein the calculating matches the three-dimensional rectangular coordinate system with a position of two-dimensional coordinates of a display;
• and
• superimposing an image of a sound beam image that shows the locus of the sound beam and the locus of the reflected sound beam onto the predetermined real space by generating a sound beam image on the display, based on a result of the calculating.
