Embodiment 1

[0025] figure 1 It is a flow chart of a multimedia content recommendation method provided by Embodiment 1 of the present invention. This embodiment is applicable to various multimedia content recommendation scenarios. The method can be executed by a multimedia content recommendation device, and specifically includes the following steps:

[0026] Step S110, acquiring the physiological signals of the user in the vehicle at least two moments;

[0027] In the embodiment of the present invention, the user in the vehicle is any user in the vehicle, which is equivalent to a person in the vehicle and is a provider of physiological signals at each moment. The user in the car can be the driver or the passengers. The physiological signals at at least two moments are physiological signals collected by the sensor from the user in the vehicle at any two different moments.

[0028] Specifically, the physiological signals include: skin conductance signals, heart rate signals, electrocardiog...

Abstract

The invention discloses a multimedia content recommendation method and device, a vehicle and a storage medium. The method comprises the steps of obtaining physiological signals of a user in the vehicle at at least two moments; determining the emotional state of the user in the vehicle at each corresponding moment according to each physiological signal; determining emotional state changes of the user in the vehicle at adjacent moments, and determining multimedia recommendation contents at the adjacent moments; determining to-be-recommended target multimedia content according to the emotional state change of the user in the vehicle at each adjacent moment and the corresponding multimedia recommendation content, wherein the emotional state comprises concentration degree and anxiety degree. According to the embodiment of the invention, the to-be-recommended target multimedia content is determined by judging the effectiveness of the recommended multimedia content according to the emotionalstate change of the user in the vehicle, so that the emotion of the user in the vehicle is relieved and driving safety is guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a multimedia content recommendation method, device, vehicle and storage medium. Background technique [0002] With the rapid development of intelligent devices, it is very common to carry multimedia devices on vehicles. Existing multimedia devices mounted on vehicles can randomly recommend multimedia content for users in the vehicle, so as to ease the emotional state of users in the vehicle, further improve the concentration of users in the vehicle, and provide a basis for safe driving. However, the way in which the existing in-vehicle multimedia devices recommend multimedia content is relatively random or is recommended according to the historical playback content of the multimedia device, and cannot target the recommended multimedia content according to the current emotional state of the user in the vehicle. Contents of the invention [0003] ...
