| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Sleep posture influences sleep quality and is also considered linked to some diseases. Therefore, estimating one's sleep posture is an important health issue. In this paper, we propose a method to estimate sleep posture from compressed beamforming feedback matrices (CBFM) obtained from Wi-Fi packets. In this method, we extract features from denoised CBFM and adopt principal component analysis to the features. After that, we use a support vector machine (SVM) or random forest (RF) to estimate sleep postures. The experimental result shows that our method was able to obtain 89.2% accuracy at the maximum in estimating sleep posture with SVM. |
