Zoom's gesture recognition feature allows users to raise their hand or give a thumbs up during virtual meetings, eliminating the need to click a button. To enable this feature, users can select it from the Zoom settings or meeting control bar. Once enabled, users can use gestures to react to messages in real-time, such as giving a thumbs up or raising their hand, which will be displayed as an emoji in their video. However, there are some common issues that may cause frustration, including gesture recognition not recognizing certain hand positions or palm orientations, and the feature being distracting for presentations or ASL classes.
