For example, a yellow triangle, a red circle, and a green rectangle may be sequentially displayed in the display screen according to a set period.
In this embodiment, in the process of executing the driving interference task by the user, if the currently displayed test pattern is observed through the remaining light, the index finger may be used to touch the thumb, the fingertip sensor is instructed to feed back a touch response to the control terminal, which indicates that the user has observed the currently displayed test pattern, and the control terminal receives the touch response, which may be used to determine the reaction time of the user for the test task.
And step 230, calculating the reaction time of the user to each test pattern according to the touch response.
In this embodiment, after receiving a touch response sent by a user through a fingertip sensor, the reaction time of the user to each test pattern is calculated according to the touch response. Illustratively, when the touch response is received, the receiving time of the touch response is recorded, and the time difference between the receiving time and the display time of the corresponding test pattern is calculated as the reaction time of the user to the current test pattern.

For example, after the user executes the driving interference task, a plurality of graphic shapes can be displayed on the screen of the control terminal at the same time, the user needs to sequentially select the test graphic shapes appearing in the display screen according to self memory, then, a plurality of colors are displayed on the screen of the control terminal, the user selects the graphic colors appearing in the display screen according to self memory, and finally, the graphic shapes, the sequence and the graphic colors selected by the user are used as memory result data.
And step 250, determining the driving interference degree of the driving interference task to the user according to the reaction time and the memory result data.
In the embodiment, the driving interference degree of the driving interference task to the user is determined through the reaction time of the user for the test task when the driving interference task is executed and the memory result data fed back by the user for the test task after the driving interference task is executed.
