Development of a User-Friendly Emergency Watch Application for Elderly Safety

The client faces challenges in providing elderly and at-risk populations with a stylish, easy-to-use wearable device capable of quickly triggering emergency actions such as calls, alerts, or sounds. Existing solutions are bulky or complex, leading to usability issues and low adoption among target users.

A mid-sized healthcare technology company specializing in wearable safety devices designed for elderly users seeking reliable emergency assistance solutions.

• Create a highly responsive and reliable mobile application to interface with the wearable device in under 2 months.
• Ensure seamless Bluetooth Low Energy (BLE) connectivity between the device and the mobile app, including stable pairing and real-time alerts for disconnection.
• Implement core functionalities such as initiating emergency calls, sending location-based alerts via email, and triggering audible signals, with an emphasis on ease of use for elderly users.
• Design a simple, accessible UI/UX aligned with platform-specific human interface guidelines, prioritizing minimalism and clarity.
• Allow users to customize button actions (single press, double press, long press) and assign emergency or convenience functions accordingly.
• Support multi-language localization with a default language (e.g., English) and the ability to add other languages.
• Collect user interaction data through integrated analytics to monitor feature popularity and improve engagement.

• Bluetooth LE (BLE) pairing and connection management with status notifications for connection loss.
• User-friendly main menu with navigation tabs for device control, overview of assigned actions, and help resources.
• Configuration interface to assign specific actions to different button press types (single, double, long press).
• Location tracking capabilities to embed GPS coordinates in alerts and emails.
• Predefined actions: Play loud sound for device locating, initiate emergency calls, and send location-based emails via integrated communication APIs.
• Local data storage of device pairing info and button-action mappings, using shared preferences or equivalent secure storage.
• First-time setup flow guiding users through Bluetooth pairing and permission grants.
• Multi-language localization support for accessibility.
• Notification system for Bluetooth disconnection, setup completion, and action failures.

• Bluetooth GATT services for communication with wearable device buttons.
• GPS services for real-time location tracking and embedding coordinates in communications.
• VoIP API (e.g., Twilio) for initiating emergency calls.
• Email service API for sending alerts with embedded GPS data.
• Firebase Analytics for user interaction and feature usage tracking.

• App should establish BLE connection within 5 seconds during pairing.
• Real-time notifications for disconnection or errors should be delivered within 1 second.
• Battery optimized to minimize power consumption during BLE operations and background activity.
• Secure storage of device information and user preferences, complying with data protection standards.
• High availability and stability: App must pass testing with no critical crashes or significant bugs before deployment.
• Accessibility features including large buttons, high contrast UI, and support for assistive technologies.

The proposed application aims to provide a reliable, user-friendly emergency solution tailored for elderly and at-risk populations. By leveraging seamless BLE connectivity, simple UI, and robust emergency communication features, the project is expected to increase user safety and confidence. Anticipated outcomes include rapid deployment within two months, high user satisfaction due to ease of use, and enhanced safety monitoring through integrated analytics, leading to greater market adoption and improved quality of life for users.
