Developers are increasingly focusing on creating user experiences that retain users by integrating real-time interactions and innovative technologies like voice, augmented reality (AR), and virtual reality (VR), moving beyond traditional screen-based interfaces. This evolution is exemplified by the development of a project called Smart-Intercom, an Alexa skill designed to transform the typical house intercom experience. It leverages real-time communication by allowing users to interact via voice devices, using tools like PubNub to execute complex logic and provide instant responses. The project highlights the challenges of designing voice applications with limited interfaces and presents solutions such as using Storyline for intuitive interaction design and React Native for companion app development. By making API requests to perform tasks remotely, the project demonstrates how developers can create seamless, integrated user experiences that extend beyond conventional applications, with potential future integrations into IoT devices. All the necessary code is available on GitHub to enable further exploration and customization.
