The use of pattern matching for impact localization in solid object is a new attractive approach for the application of computer human interaction. In this paper, a coherence function technique is introduced for Tangible Acoustic Interface (TAI) using the Location Template Matching (LTM) approach. A simple workflow is proposed for the purpose of evaluating the performance of different TAI techniques and to investigate the effect of various parameters based on experimental data. Performance analysis shows that the method of magnitude squared coherence outperforms the traditional method of using time domain cross correlation for both of resolution and reliability aspects.
