Development of approaches to the choice of methodology for designing a smart system interface

Abstract

The article addresses one of the key problems of modern digital design – the integration of UX/UI into smart systems, since in today’s digital world high-quality user interface (UI) design is a crucial factor in the success of software products and services, while usability and positive user experience (UX) directly influence customer satisfaction and the competitiveness of companies. Due to the integration of computing and communication tools, the number of everyday objects acquiring “smart” characteristics is growing exponentially. This, in turn, significantly increases the importance of creating intuitive user interfaces for managing “smart” objects and systems operating in dynamic, context-dependent environments. The most popular methodological approaches to interface design are analyzed, their comparison carried out, and the advantages and disadvantages of each outlined. A number of criteria for selecting interface design methods for smart systems are identified and substantiated, including user-centeredness, development flexibility, rapid prototyping, scalability, and integration capabilities. The application of the analytic hierarchy process (AHP) is proposed to select the most appropriate interface design methodology, and its use is demonstrated with the example of a smart thermostat as a representative element of a “smart home.” The expediency of a combined approach in choosing methodologies for designing interfaces of intelligent systems is substantiated, which makes it possible to effectively take into account the specifics of different stages of the project life cycle. It is concluded that the further development of smart system interfaces will be determined by the increasing role of artificial intelligence, personalization, and multimodal interaction, while integration with augmented and mixed reality technologies will open new opportunities for ensuring more natural and convenient user interaction with digital services.
