| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | By popularization of Internet services, a new way of rendezvous is required. One example is rendezvous with an acquaintance only on SNS (Social Network Service). In the case of the rendezvous with a person without the acquaintance in real world, the easy way to find the partner is required. One answer is to provide the distance and direction to the partner. Although conventional works have provided keys to perform distance estimation with only commodities like smartphones, direction estimation requires pre-planned infrastructure or special hardware. In this paper, we newly propose a direction estimation method, which monitors Doppler Effect of acoustic waves generated by user’s simple motion. Moreover, we implemented the proposed method, and measured its performance under real-world conditions. The experimental results show that the estimation error ranges within 18.0 degrees, which is practical for the above use cases. | |
