To access emotion effects in PRISM, tap the effects icon ( 마술봉

) next to the **Go Live** button, and then select the emotion effects icon ( 랜덤 감정 이펙트

), as shown in the image below.

You can tap on each effect to apply it. Some effects support face detection, which tracks your face in real time and positions the effect accordingly on the screen. Face-detecting effects are marked with a small face icon (![](https://1019928184-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlISC5rfB4Hnmbsjf8phq%2Fuploads%2FJ4rMQsHQ3Mtg7HtvSHxI%2Fmask.png?alt=media\&token=9a07e747-ae39-4f3a-a254-28406c8ee42a)) on their thumbnails for easy identification.

To add an effect to your favorites, simply long-press the effect. You can access your favorites by selecting the **Favorites** tab ( 드로잉 이벤트

) located on the left side of the tab bar. In the **Favorites** tab, effects are displayed in order of most recent use, with favorited effects appearing first. To remove a favorited effect, long-press it again.

There are eight emotion categories: **Greet**, **Love**, **Congrats**, **Awesome**, **Fun**, **OMG**, **Angry**, and **Sad**. Additionally, there are two special categories: **RandomTouch** and **Shopping**. **RandomTouch** effects appear in random positions and sizes each time you tap on them, adding a playful and dynamic element to your broadcast.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://guide.prismlive.com/mobile/guides/widgets-and-effects/emotion-effect/using-emotion-effect.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
