Emerging from the software crisis of the 1960s, conventional software systems have vastly improved through Software Engineering (SE) practices. Simultaneously, Artificial Intelligence (AI) endeavors to augment or replace human decision-making. In the contemporary landscape, Machine Learning (ML), a subset of AI, leverages extensive data from divers...

In recent years, the emergence of viral infections has posed significant challenges to healthcare systems worldwide. Timely and accurate detection of viral infections is essential for effective patient care and outbreak management. Although the World Health Organization has declared an end to the emergency phase of the Covid-19 pandemic, it is stil...

Objectives This article presents a systematic review of recent advancements in telemedicine architectures for continuous monitoring, providing a comprehensive overview of the evolving software engineering practices underpinning these systems. The review aims to illuminate the critical role of telemedicine in delivering healthcare services, especial...

Omnidirectional videos have become a leading multimedia format for Virtual Reality applications. While live 360 $^\circ$ videos offer a unique immersive experience, streaming of omnidirectional content at high resolutions is not always feasible in bandwidth-limited networks. While in the case of flat videos, scaling to lower resolutions works well...

Technological interventions can play a significant role to keep optimal growing conditions in greenhouse industries with varying seasons and improve environmental performance by maintaining heating, cooling, and humidity levels. The research reported in this paper aims to integrate an Automated Climate Monitoring System (ACMS) for greenhouse in Eth...

Quality of Experience (QoE) is indelibly linked to the human side of the multimedia experience. Surprisingly, however, there is a paucity of research which explores the impact that human factors has in determining QoE. Whilst this is true of multimedia, it is even more starkly so as far as mulsemedia - applications that involve media engaging three...

Quality of Experience (QoE) is inextricably linked to the human side of the multimedia experience. Whilst there has been a considerable amount of research undertaken to explore the various dimensions of QoE, one facet which been relatively unexplored is the role of individual differences in determining an individual’s QoE. Whereas this is certainly...

In recent years, the ultra-wideband (UWB) radar technology has shown great potential in monitoring activities of daily living (ADLs) for smart homes. In this paper, we investigate the significance of using non-wearable UWB sensors for developing non-intrusive, unobtrusive, and privacy-preserving monitoring of elderly ADLs. A controlled experiment w...

Sensory studies emerged as a significant influence upon Human Computer Interaction and traditional multimedia. Mulsemedia is an area that extends multimedia addressing issues of multisensorial response through the combination of at least three media, typically a non-traditional media with traditional audio-visual content. In this paper, we explore...

Using olfactory media to enhance traditional multimedia content opens up novel opportunities for user interactions. Whilst the influence of olfaction on user experience in mulsemedia (multiple sensorial media) environments has been previously studied, the impact of the fundamental dimensions of scent intensity and valence (odor hedonic dimension or...

Multisensory effects devices have been increasingly developed by research groups and companies with the aim of creating more immersive experiences for users by generating tactile, olfactory, and gustatory sensations. These technologies have been applied to areas such as entertainment, healthcare, education, culture, and marketing. This article brin...

One of the main challenges in current multimedia networking environments is to find solutions to help accommodate the next generation of mobile application classes with stringent Quality of Service (QoS) requirements whilst enabling Quality of Experience (QoE) provisioning for users. One such application class, featured in this paper, is 360° muls...

A great deal of research effort has been put in exploring crossmodal correspondences in the field of cognitive science which refer to the systematic associations frequently made between different sensory modalities (e.g. high pitch is matched with angular shapes). However, the possibilities cross-modality opens in the digital world have been relati...

Dispositivos de efeitos multissensoriais estão cada vez mais sendo desenvolvidos por grupos de pesquisa e empresas com o objetivo de melhorar a qualidade da experiência (QoE) dos usuários, criando sensações de vibração, toque, cheiro, vento e assim por diante. Este breve artigo resume os esforços recentes de dispositivos táteis, olfativos e gustati...

Previous research has shown that adding multisensory media—mulsemedia—to traditional audiovisual content has a positive effect on user Quality of Experience (QoE). However, the QoE impact of employing mulsemedia in 360° videos has remained unexplored. Accordingly, in this paper, a QoE study for watching a 360° video—with and without multisensory eff...

Multisensory experiences have been increasingly applied in Human-Computer Interaction (HCI). In recent years, it is commonplace to notice the development of haptic, olfactory, and even gustatory displays to create more immersive experiences. Companies are proposing new additions to the multisensory world and are unveiling new products that promise...

Different senses provide us with information of various levels of precision and enable us to construct a more precise representation of the world. Rich multisensory simulations are thus beneficial for comprehension, memory reinforcement, or retention of information. Crossmodal mappings refer to the systematic associations often made between differe...

The human brain has evolved to learn, adapt and operate optimally in multisensory settings. Exploring the multisensory-phenomena in a human computer interaction (HCI) context could help design interfaces and displays that tap into users' mental models. In this paper we explore the influence of crossmodal correspondences on the Quality of Experience...

Education is one among the many social services that enjoyed information technology as an enabler. The digital media and e-learning systems have played significant role as a learning content as well as learning platform with the aim to enhance access to education and quality of learning. In this paper, we investigate the practice of adopting digita...

Media content is consumed more and more on digital and mobile devices. Internet of Things enables media providers to move beyond the traditional content and entertainment space and offer a plethora of new services that creates an engaging user experience around content. However, one of the questions that remain open is how to design content that en...

Today, smartphones are capable of hosting a large variety of applications as clients for the classical as well as service-based business applications. They can also be envisaged for composing and hosting service-based thick client applications aiming at exploiting users’ creativity and resolving mobile connectivity challenges, respectively. However...

Ensuring accessibility of utility and social services is one of the public obligations of governments. Today, nations make use of the notion of e-government to expose such services to citizens. In line with this, many public organizations in Ethiopia are automating their workflows, and the Ministry of Communication and Information Technology (MCIT)...

Considering end-user research and proliferation of smartphones and REpresentational State Transfer (REST) interfaces, we envisage that smartphone owners can innovate to compose applications on the small screen. This paper presents the design and evaluation of a REST service development framework (viz, REST4Mobile) with the aim to enhance the usabil...

HTML5 can be used to develop client applications by composing REST web services within the context of Web 2.0. However, the possibility of implementing cross-platform smartphone applications with REST services needs to be studied. Accordingly, we developed a REST-based cross-platform application with PhoneGap. The application was deployed on the An...
