A system for coordinating a presentation on a group of mobile computing devices in a area. The system comprises a plurality of mobile computing devices for running a software application which is adapted to connect to the server and display data on the mobile computing devices, a drone-mounted camera for monitoring the lighting output of the mobile computing devices in the given area and a processor for transmitting data to each mobile computing device in the group to activate the lighting output of each mobile computing device. The processor receives data from a camera about the positions of each mobile computing device within the given area, the server sends data to mobile computing devices in the correct position within the given area and the data controls the lighting output of each mobile computing device so as to form a presentation across all of the mobile computing devices in the given area.

Aspects provided may allow for a user to block charges from an entity without having to contact the entity. After detecting that the user has enrolled in a trial or subscription of an entity offering, the user may be provided with the option to block charges from the entity. Using incoming data, charges from the blocked entity may be identified and prevented from being applied to the user. Further aspects may provide for more discrete charge blocking, such as blocking charges for one activity while allowing other charges for different activities from the same entity to go through, and training an identification model that isolates the entity identifier from the incoming data and matches the entity identifier to known entities.

A method, a device, and a non-transitory computer-readable recording medium are provided for creating a chatbot scenario in consideration of a response rate. A chatbot scenario creation method may include obtaining chatbot sentence components and at least one chatbot sentence including the chatbot sentence components from a chatbot; predicting a response rate of a user for at least one chatbot sentence based on a predicted response rate preset for each of chatbot sentence components; and providing the predicted response rate of the user for the at least one chatbot sentence.
