Disclosed are systems, methods, and non-transitory computer-readable media for determining attention based on user interactions. While content is being presented by a client device, an attention determination system causes presentation of a prompt object on a display of the client device. The prompt object starts from an entry point and traverses a path across the display. While the prompt object is traversing the path across the display, the attention determination system detects a user input at a point on the display that is within a threshold distance of a current position of the prompt object along the path. The attention determination system determines an attention level of a user of the client device based on the user input.
