Abstract: To allow for greater interactivity in video chat environments, displaying multiple effects from a sender of a first electronic device to a chat client of a second electronic device on a video chat region starts with the sender selecting an effect. If the selected effect has a predetermined mapping interactive effect, the interactive effect is displayed on the chat client. Then, the sender applies the effect or the interactive effect to an application region of the video chat region of the chat client. The application region is a partial or an entire region of the video chat region.
