Background of study: The rapid development of IoT-enabled systems has transformed user interaction by enabling intelligent, responsive, and interconnected digital environments. However, existing studies often emphasize traditional usability factors while overlooking emerging interaction attributes essential for next-generation Digital Twin and IoT-based interfaces.
Aims and scope of paper: This study aims to investigate next-generation Digital Twin user experience (UX) by exploring interactive IoT design attributes, including gesture-based interaction, gaze tracking, multimodal interfaces, and AR-assisted usability. The research also develops an enhanced usability framework that integrates efficiency, cognitive load, and user satisfaction metrics.
Methods: Using a mixed-method approach, the study integrates quantitative evaluations (task completion time, error rates) and qualitative assessments (NASA-TLX, SUS). Data were collected from open-source IoT usability datasets and supported by prototype testing, including touch-based, voice-assisted, gesture-controlled, and AR-enhanced interfaces.
Result: Findings show that AR-enhanced and touch-based interfaces significantly improve task efficiency, reduce cognitive load, and increase user satisfaction. Gesture-based systems, while offering immersive interaction, exhibit higher error rates and cognitive strain. Users also expressed concerns regarding data security and interface complexity in IoT-enabled environments.
Conclusion: IoT-enabled Digital Twin interaction offers substantial improvements in usability and engagement, particularly through AR and touch-based designs. However, challenges persist in gesture accuracy, voice recognition consistency, and privacy risks. This research establishes a structured framework for future IoT-UX development, emphasizing adaptive, intuitive, and user-centered design principles.
Background of study: IoT enabled systems such as mobile phones, smart homes, and medical applications play a significant role in improving convenience and usability in everyday life. The combination of IoT networks with graphical user interface designs, including websites and online applications, continues to grow rapidly. Despite this progress, interactive usability challenges remain, especially in aligning IoT technologies with human centered interaction principles.
Aims and scope of paper: This study explores the usability of interactive design and identifies new attributes that contribute to improving user experience in IoT enabled systems. It aims to classify logical and physical attributes that influence usability and to propose new interactive dimensions for IoT based design.
Methods: The study uses a descriptive and analytical approach based on a review of relevant literature and conceptual analysis. Logical and physical usability attributes were examined to understand their roles in interactive design and user experience across IoT environments.
Result: The results reveal that two major factors, logical and physical attributes, are fundamental to interactive design. These attributes can guide new rules for IoT based usability, expanding human computer interaction beyond traditional interfaces such as keyboard, mouse, and screen, and including motion, gaze, and posture as part of new interaction mechanisms.
Conclusion: This study focuses on interface usability to help developers create more attractive and user friendly designs. The findings open new research areas in interactive IoT systems and contribute to the development of adaptive, efficient, and human oriented interface design principles for future IoT applications.
