The embodiment of the present invention relates to the field of smart home, and discloses a head position determination method and a pillow. A plurality of thin film piezoelectric switches are arranged in the pillow, and a gap between two adjacent thin film piezoelectric switches is less than a preset threshold, wherein the head position determination method comprises the steps: monitoring closing/opening of the thin film piezoelectric switches in the pillow; determining the head position according to the closing information of the thin film piezoelectric switches. Since the thin film piezoelectric switches are closed by force, when the head of a user is pillowed on the pillow, the position of the head of the user can be determined by detecting closing or opening of the thin film piezoelectric switches, and the distance between two adjacent thin film piezoelectric switches is less than the preset threshold to reduce the risk that the head of the user is fallen into the gap between thetwo adjacent thin film piezoelectric switches when the head of the user is pillowed on the anti-snoring pillow, thus improving accuracy of detection of the head position of the user.
