Information processing system, apparatus and method for measuring a head-related transfer function

An apparatus for measuring a Head-Related Transfer Function (HRTF), the apparatus comprising:

• a processing device configured to control:
• determining position and orientation of an object relative to an audio signal generating device having a first known position and orientation, based on tracking information indicating position and orientation of the object;
• generating movement data indicating direction of movement to position the object at a target position and orientation in relation to a predetermined position and orientation of the audio signal generating device, according to the relative position and orientation of the object, in which the target position and orientation of the object is a position and orientation for the object at which an audio signal measurement is to be performed for determining a first HRTF;
• and
• responsive to a determination that the object is at the target position and orientation following the generating of the movement data, supplying an audio signal from the audio signal generating device which is at the first known position and orientation while the object is at the target position and orientation;
• and
• determining the first HRTF based on detection at the object of the audio signal.

A non-transitory storage medium on which is recorded a program executable by a computer, the program comprising:

• determining position and orientation of an object relative to an audio signal generating device having a first known position and orientation, based on tracking information indicating position and orientation of the object;
• generating movement data indicating direction of movement to position the object at a target position and orientation in relation to a predetermined position and orientation of the audio signal generating device, according to the relative position and orientation of the object, in which the target position and orientation of the object is a position and orientation for the object at which an audio signal measurement is to be performed for determining a first HRTF;
• and
• responsive to a determination that the object is at the target position and orientation following the generating of the movement data, supplying an audio signal from the audio signal generating device which is at the first known position and orientation while the object is at the target position and orientation;
• and
• determining the first HRTF based on detection at the object of the audio signal.
