Thesis is devoted to the creation of computer animation for character's 3Dmodel on the base of motion capture technology.The first section describes the concept of computer animation, its types and applications. The basics of motion capture technology as well as a comparative analysis of different types of motion capture systems, their advantages and disadvantages. The process of creating face animation based on motion capture technology is also considered.The second section provides a rationale for the choice of tools and working material to perform the practical part of the work.The third section presents the practical side of the process of creating computer animation and analyzes the results. The analysis showed the presence of some shortcomings both in the work of means of creating animation based on motion capture technology, and the technology as a whole.

The present study has two purposes. One is to examine a simulation method for localizing a sound image. The authors propose a parametric HRTF model to simulate vertical sound localization. The parametric HRTF is recomposed only of the spectral peaks and notches extracted from the measured HRTF, and the spectral peaks and notches are expressed parametrically with center frequency, level, and sharpness. The other purpose is to clarify the contribution of each spectral peak and notch as a spectral cue. Localization tests were carried out in the upper median plane using the subjects’ own measured HRTFs and the parametric HRTFs with various combinations of spectral peaks and notches. The results show that the parametric HRTF recomposed using the first and second notches (N1 and N2) and the first peak (P1) provides almost the same localization accuracy as the measured HRTFs. Observations of the spectral peaks and notches indicate that N1 and N2 change remarkably as the source elevation changes, whereas P1 does not depend on the source elevation. In conclusion, N1 and N2 can be regarded as spectral cues, and the hearing system could utilize P1 as the reference information to analyze N1 and N2 in ear-input signals.

We analyzed the permeability measurement error of a low permeance thin film. We clarified that the noise voltage was excited by a current loop which is composed of the coaxial cable and the ground plane. The current loop should be removed for high sensitivity of the permeameter. The permeability of a high electrical resistivity film (CoFeHfO) has been demonstrated 1 MHz–3.5 GHz.
