| Abstract(in English) | The aim of this paper is to achieve ad-hoc grouping systems enhanced by ambient sounds or sound-fields. As an elemental technology of ad-hoc grouping, systems have to be equipped with a search engine with sufficient accuracy to find out users who are in similar contexts. Systems require another similarity criterion for sound-fields. Because search results from well-known similarities, such as cosine-similarity, cannot exclude false negative and cannot restrict false positives. Moreover, in order to cover a wide-variety of mobile devices including smartphones, we have the problem of the deterioration of search accuracy due to differences in microphone performances. We may also have to decrease the system-wide load. This suggests that original sound-field data should be resized as small as possible without losing valuable features to flexibly recognize different contexts. We thus propose a new similarity criterion on sound-fields for ad-hoc grouping. We also show experimental results to ensure all requirements are fulfilled. |
