We are university students working on a smart wristband project designed to protect pilgrims (Hajj/Umrah) and field workers in Saudi Arabia from excessive sun and heat exposure. The wristband will be programmed to detect UV light intensity and some basic vital indicators, then connected to a mobile application that displays real-time readings. The app will: • Show live environmental and health data (e.g., UV level, temperature, pulse rate). • Provide smart recommendations and reminders (e.g., suggesting safer hours for Tawaf, reminding workers to drink water, etc.). • Include a heat map visualizing temperature and UV intensity in nearby areas. • Serve as both a personal health assistant for users and a national preventive health data tool for broader analysis. Note: The app will be a prototype for presentation purposes only. All data will be simulated (dummy data), and no real sensor integration or backend will be required. ⸻ App Architecture & Connection Flow 1. Smart Wristband → Mobile App The wristband will transmit UV and basic vital data to the mobile app (simulated in the prototype). 2. Mobile App → Central Dashboard The app will send summarized readings to a central dashboard interface (also simulated) that visualizes overall data trends and the heat map. 3. Dashboard → Preventive Insights The dashboard will demonstrate how collected data can be used for national preventive health analysis and decision-making support. ⸻ App Structure (Screens to be Designed) 1. Splash Screen Displays the project logo for a few seconds before entering the app. 2. Onboarding Screen Introduces the app’s purpose and benefits for pilgrims and field workers with visuals or simple icons. 3. Login Screen Simple login interface allowing users to access their personal data and readings. 4. Home Screen Shows a summary of the current readings (UV index, temperature, health status, etc.). 5. Live Readings Screen Displays real-time readings (simulated values) such as UV level, temperature, and pulse rate in a clear numerical format. 6. Recommendation Screen Provides intelligent suggestions like: • “Avoid direct sunlight now, UV is high.” • “Recommended Tawaf time: 12 PM.” • “Drink water to stay hydrated.” 7. Heat Map Screen Displays an interactive heat map showing UV and temperature levels around the user (sample visualization, no live data). 8. Profile Screen Shows user details with options to edit name, language, and general settings. 9. About Screen Describes the project idea, objectives, and the development team’s role in protecting pilgrims and field workers from heat and UV exposure. 10. Notifications Screen Lists alerts and reminders such as: • High UV exposure warnings • Water-drinking reminders • Safety recommendations ⸻ Important Notes • The app will be UI/UX functional only (front-end prototype). • All readings, heat maps, and notifications will be dummy data for presentation purposes. • The design should emphasize simplicity, clarity, and health-oriented visuals suitable for pilgrims and outdoor workers.
