Emojis are a must-have tool in today's online communications as they help add color to text-based chatting and allow users to better express the emotions behind their words. Since the number of preset emojis is always limited, many apps now allow users to create their own custom emojis to keep things fresh and exciting.
For example, in a social media app, users who do not want to show their faces when making video calls can use an animated character to protect their privacy, with their facial expressions applied to the character; in a live streaming or e-commerce app, virtual streamers with realistic facial expressions are much more likely to attract watchers; in a video or photo shooting app, users can control the facial expressions of an animated character when taking a selfie, and then share the selfie via social media; and in an educational app for kids, a cute animated character with detailed facial expressions will make online classes much more fun and engaging for students.
