Abstract: Various embodiments relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. In those embodiments, an awake time period and a sleep time period of a user is determined by the terminal, and parameter thresholds in the awake time period and the sleep time period is determined by the terminal. In those embodiments, a light parameter in a current time period is obtain by the terminal, and based on the light parameter in the current time period, a light parameter of light emitted by a light source device is then adjusted by the terminal.

Abstract: A method includes: obtaining an electrocardiosignal of a target user; importing the electrocardiosignal into a preset atrial fibrillation signal classification model, to obtain a signal type, of the electrocardiosignal, output by the atrial fibrillation signal classification model, where the atrial fibrillation signal classification model is obtained through training with an atrial fibrillation patient being a model training sample; and calculating, based on the signal type of the electrocardiosignal, a risk level of an atrial fibrillation occurrence, to predict whether the target user is to have an atrial fibrillation attack.
