Abstract
Various implementations disclosed herein include devices, systems, and methods that determine an attentive state of a user based on physiological data associated with a physiological response of the user to an auditory stimulus. For example, an example process may include selecting an auditory stimulus based on a characteristic of an environment, presenting the auditory stimulus to a user, obtaining, using a sensor, first physiological data associated with a physiological response of the user to the auditory stimulus, and assessing an attentive state of the user based on the physiological response of the user to the auditory stimulus.
Claims21
A method of attentive state assessment, the method comprising:
- at a device comprising a processor and a speaker:
- determining a type of an environment of a user based on sensor data;
- selecting an auditory stimulus based on selecting a sound from a plurality of sounds corresponding to the determined type of the environment, the auditory stimulus being selected to evoke a physiological response for assessing an attentive state of the user and is associated with a location in a three-dimensional (3D) coordinate system corresponding to the environment;
- presenting the auditory stimulus to the user via the speaker at the location in the 3D coordinate system;
- obtaining, using a sensor, first physiological data associated with a physiological response of the user to the auditory stimulus;
- and
- assessing the attentive state of the user based on the physiological response of the user to the auditory stimulus.
A device comprising:
- a speaker;
- a non-transitory computer-readable storage medium;
- and
- one or more processors coupled to the non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium comprises program instructions that, when executed on the one or more processors, cause the one or more processors to perform operations comprising:
- determining a type of an environment of a user based on sensor data;
- selecting an auditory stimulus based on selecting a sound from a plurality of sounds corresponding to the determined type of the environment, the auditory stimulus being selected to evoke a physiological response for assessing an attentive state of the user and is associated with a location in a three-dimensional (3D) coordinate system corresponding to the environment;
- presenting the auditory stimulus to the user via the speaker at the location in the 3D coordinate system;
- obtaining, using a sensor, first physiological data associated with a physiological response of the user to the auditory stimulus;
- and
- assessing the attentive state of the user based on the physiological response of the user to the auditory stimulus.
A non-transitory computer-readable storage medium, storing program instructions executable on a device to perform operations comprising:
- determining a type of an environment of a user based on sensor data;
- selecting an auditory stimulus based on a selecting a sound from a plurality of sounds corresponding to the determined type of the environment, the auditory stimulus being selected to evoke a physiological response for assessing an attentive state of the user and is associated with a location in a three-dimensional (3D) coordinate system corresponding to the environment;
- presenting the auditory stimulus to the user via a speaker at the location in the 3D coordinate system;
- obtaining, using a sensor, first physiological data associated with a physiological response of the user to the auditory stimulus;
- and
- assessing the attentive state of the user based on the physiological response of the user to the auditory stimulus.
