Real-time production of sound-feeling of an object passing by a human head

Abstract

A sound perceived by a person varies in its characteristics as an object nearby the person's head changes its position in a sound field. This phenomenon helps us to determine the motion of such object. Hence, reconstruction of this phenomenon could emphasize the reality of an object in a virtual world whichever the object is in or out of the visual field. This paper consists of two parts. The first part is dedicated to developing a technique to reconstruct this phenomenon with low computational cost using the Karhunen-Loeve expansion for real time applications. The second part is dedicated to investigating the effects of this technique by means of two experiments. The results of the experiments show that the proposed technique is effective for people to be able to distinguish the motion of an object in the virtual world.
