Summary

Give chatbot a avatar/icon. The chatbot is animated to perform certain visual actions during interactions. For instance, when the TTS feature is activated, the chatbot's mouth opens to simulate speech.

Problem Statement

Is this feature addressing a specific problem or gap? If so, describe the problem in detail and explain why it needs to be solved.
Currently, most chatbots rely solely on text or voice responses without any visual feedback, making interactions feel less engaging and less human-like. The lack of a visual identity and expressiveness limits user immersion and emotional engagement.

Proposed Solution

Describe your proposed solution. How would the feature work? What are the key components or functionality it would involve?
Avatar customization – Developers can assign a visual identity to the chatbot.
TTS-synced animation – When the chatbot speaks via TTS (text-to-speech), its mouth animates in sync with the audio.
Emotion expression – Optional animations (e.g., smiling, blinking) to reflect chatbot tone or message context.

Benefits

Explain how this feature would improve the project. What advantages does it bring to the users or developers?
Improved user engagement – Visual avatars with expressions make the chatbot feel more alive and personable.
Enhanced accessibility – Combining visual and audio feedback makes the chatbot more inclusive.
