6. Signature Design Concept

The lemon-jarvis app will feature a dynamic holographic interface as its signature design concept. Upon launching the app, users will be greeted with a 3D holographic assistant avatar that appears to float above the screen. The avatar will respond to user commands with subtle animations, such as nodding, gesturing, or changing expressions.

Key Features:

• Interactive Holographic Avatar: Users can customize the avatar's appearance, including gender, voice, and outfit.
• Ambient Animations: The background will feature a living nebula effect, with soft, flowing colors that shift based on the time of day (e.g., warm tones in the morning, cool tones at night).
• Micro-Interactions: Buttons and icons will have hover effects that mimic ripples in water, creating a tactile feel.
• Voice Wave Visualization: When the user speaks, a real-time waveform animation will appear around the avatar, visualizing the input.

This design will make the app feel alive and futuristic, leaving a lasting impression on users.

7. Non-Functional Requirements

• Performance: The app should respond to user commands within 1 second.
• Scalability: The system must handle up to 10,000 concurrent users without degradation in performance.
• Security: User data must be encrypted both in transit and at rest.
• Localization: The app should support multiple languages, with a focus on English and Indian regional languages.
• Compatibility: The app must be compatible with Android 8.0 (Oreo) and above.
