Billions of people live with visual and/or hearing impairments. Regrettably, their access to systems remains delayed, leaving them socially excluded. The need for universal access of next-generation systems and users’ inclusion is paramount. We pose that a smart society should respond to this crucial need. Following ability-based design principles, we introduce a simulated social robot that adapts to users’ sensory abilities. Its working was assessed via a Rock–Paper–Scissors game in an Intelligent Environment (IE), using three modes: where the user is able to see and hear, only see, or only hear. With this game, two user-studies were conducted using the UMUX-LITE usability score, an expectation rating, and the gap between experience and expectation, complemented with two open questions. A repeated measures Multivariate ANalysis Of VAriance (MANOVA) on the data from study 1 unveiled an overall difference between the three modes, F ( 6 , 6 ) = 6.823 , η p 2 = .872 , p = .017 . Users expected applications to be harder to use with a disability, especially a visual impairment. All modes were considered accessible, with the experience exceeding expectations for the mode with a hearing impairment. In parallel, substantial variance was observed across participants and the results from the open questions suggested improvements. To reduce this variance and increase system stability, study 2 was run with an enhanced design. A repeated measures MANOVA on the data from study 2 confirmed study 1’s findings, F ( 6 , 6 ) = 12.801 , η p 2 = .928 , p = .003 . Moreover, experiences exceeded expectations in all modes and the variance among participants was substantially decreased. We conclude that IE applications managed by a social robot can be adapted to user’s sensory abilities, improving smart society’s accessibility, and, hence, reducing social exclusion.

Food wastage because of the lack or incompletion of a household replenishment system is an essential topic to be addressed. An appropriate utilization of Internet of Things (IoT) and Artificial Intelligence (AI) technologies with particular components is needed to design a smart household replenishment system to reduce food wastage. Therefore, this systematic review is dedicated to survey papers utilizing IoT and AI tools for perishable items storage compartments, as they are always full of items that need to be monitored. This study was conducted by following the PRISMA search strategy. It examined 70 papers in chronological order starting from 2000 when LG Electronics invented the first smart refrigerator, and research on technology involvement in food storage compartments increased. This comprehensive research aims to point out the approaches, contributions, used components and limitations of the reviewed papers to develop a unified framework for a household replenishment system. The analysis resulted in 43 approaches using IoT technology, 27 using AI, and recently the use of AIoT has been trending in the past two years. This systematic review provides future directions for researchers acquired from the limitations of the reviewed papers to enhance the household replenishment system by developing and adding required features in smart food storage compartments. Further investigation into smart home appliances would lead to extensive approaches like smart shops, industries, and eventually smart cities.

The Metaverse is experiencing widespread adoption by organizations aiming to elevate brand engagement, particularly in computer engineering’s burgeoning field focused on virtual world gamification. This trend spans various sectors, including network science, smart cities, and online games. This study aims to reveal the motivations driving the use of virtual media, providing valuable insights into diverse user preferences. Integrating this information into smart city development holds promise for enhancing responsiveness to user needs, making our dataset relevant for both governmental and private entities seeking to create virtual media platforms or smart cities tailored to user demands. This research contributes to the ongoing evolution of smart city design, aligning with user motivations and adapting to evolving trends in user behavior. The findings offer a foundation for informed decision-making, promoting a user-centric and responsive approach in developing virtual experiences within the smart city context. Our research paper focuses on investigating the motivation and necessity of virtual reality (VR) games for potential integration into smart cities. Targeting a specific demographic of 40 individuals aged 18 to 24 in the capital of Thailand, we utilized correlational research methods to explore motivations and needs for VR games. Through the development of a socially virtual game-free asset using Unity, our experiments shed light on the significant motivations for Generation Z in Thailand, emphasizing convenience, product appearance, and game effects. The findings highlight the pivotal roles of social engagement and the motivation for self-disclosure in building relationships. Additionally, our study suggests that social connections and shared experiences strongly motivate individuals to participate in gaming activities. Notably, female players are significantly influenced by social connections, while branding has a minimal impact on their motivation and desire.
