Abstract: A system for generating heat map data for content. The system may include a user device, which may capture user input to begin presentation of the content and stop presentation of the content. The user device may also capture information associated with a time interval associated with the user input. The time interval may include a start time and an end time. The user device may send the user input and the information to a server. The server may collect user inputs and information from multiple user devices which are used to generate user interface data. The user interface data may be configured to cause a depiction of a user interface element. The user interface element may include one or more indicators that identify an interest portion associated with the time interval within the content. The indicators enable a user to locate or know interesting portions within the content.
