The video shows a user interacting with an online tool called 'Gripper Sizing' on the Festo website. The user adjusts parameters like 'Payload' and 'Total stroke required' on the left side of the screen. As the parameters are changed, the 'Exact result' section on the right updates, displaying different gripper models, their total stroke, and gripping force. The tool calculates and presents results, eventually showing a 'Success' message indicating items have been added to the shopping basket.
