Traditional electric curtains are usually equipped with remote controllers to control the opening and closing and position adjustment of the curtains through wireless signals, greatly simplifying the user's operation process. However, in actual use, the design of traditional remote controllers has some shortcomings, which affects the user experience.

[0003] Currently, the common electric curtain remote controllers on the market mostly use key mode to select the curtains to be controlled and adjust the opening and closing degree of the curtains. Specifically, these remote controllers generally have multiple function keys on the shell, and users press different keys to achieve different control instructions for the curtains. In addition, some remote controllers are equipped with liquid crystal displays that can display the current state of the curtains and other related information. Although these designs meet the basic needs to some extent, there are still some limitations in actual application.

At the same time, too many keys also increase the manufacturing cost, and after a long time of use, the keys are prone to wear or failure, reducing the service life of the product. Therefore, it is necessary to develop a new remote controller design scheme to overcome the above problems and improve user experience. CONTENT OF THE INVENTION
