    In an era where smartphones have become an integral part of our daily lives [1], harnessing their potential to ensure personal safety and security is of paramount importance. As these devices continue to evolve and offer an ever-expanding array of features, leveraging their advanced capabilities to create innovative solutions for emergency communication and response can significantly enhance our society's overall resilience in the face of unforeseen crisis. The seamless integration of cutting-edge technologies, such as real-time video communication and location- based services, with the ubiquity of smartphones opens new horizons in the way emergency situations can be approached. By capitalizing on the widespread adoption of smartphones, individuals can be empowered with a powerful tool that not only connects them to immediate help but also bridges the gap in communication during high-stress scenarios. Additionally, it is essential to prioritize accessibility, especially for people with disabilities, as technology and applications continue to develop and improve. For instance, this is of utmost importance in emergency call systems, as individuals with partial or total hearing loss often face challenges in communicating with emergency services. According to the state-of-the-art, several of the studied applications in Europe and America allow users to make emergency calls, but none of these applications, as far as we are aware, support emergency video calls. Furthermore, no application is known to exist in Greece, to the best of our knowledge, that enables users to contact emergency services through voice, video, or text message through the application itself, let alone one that can help users with partial or total hearing impairments. This thesis presents the design and development of an innovative emergency call application aiming at revolutionizing emergency communication and response systems. The application, based on WebRTC (Web Real-Time Communication) technology, provides users with a range of features to enable swift and effective communication during emergency situations. Through the application, users can initiate video calls with emergency operators, facilitating real- time visual communication and assessment of emergency situations. In cases where verbal communication is challenging or impossible, a chat functionality is integrated into the video call interface, allowing users to interact with call operators through text messages. Finally, should the user opt not to initiate a voice or video call and instead intend to dispatch an emergency message, an additional functionality referred to as "Image to Text" comes into play. This feature enables the user to articulate an emergency message, using icons that most accurately depict their situation, and send it to the emergency services. The Usability Evaluation of the application showcased highly promising results. User feedback highlighted the intuitive interface, seamless integration of video and chat functionalities, and the efficiency of the distress messaging system. Participants expressed high levels of satisfaction, particularly emphasizing the application's ability to support individuals with speech- related challenges, enabling them to communicate effectively either through text messages during video calls or by using the “Image-to-text” feature for sending emergency messages.
