“…The majority of the devices used were wearablesbased, thus allowing the user to move during the immersive VR experience. It should also be noted that in the majority of the cases, multimodal systems were utilized, with HR/ HRV coupled with other modalities; electrodermal activity (EDA) being the most prevalent [139,140,[143][144][145][146][147][148][149]. The next sub-section is dedicated to the measurement IMEx correlates from the EDA.…”

Virtual reality (VR) applications, especially those where the user is untethered to a computer, are becoming more prevalent as new hardware is developed, computational power and artificial intelligence algorithms are available, and wireless communication networks are becoming more reliable, fast, and providing higher reliability. In fact, recent projections show that by 2022 the number of VR users will double, suggesting the sector was not negatively affected by the worldwide COVID-19 pandemic. The success of any immersive communication system is heavily dependent on the user experience it delivers, thus now more than ever has it become crucial to develop reliable models of immersive media experience (IMEx). In this paper, we survey the literature for existing methods and tools to assess human influential factors (HIFs) related to IMEx. In particular, subjective, behavioural, and psycho-physiological methods are covered. We describe tools available to monitor these HIFs, including the user's sense of presence and immersion, cybersickness, and mental/affective states, as well as their role in overall experience. Special focus is placed on psycho-physiological methods, as it was found that such in-depth evaluation was lacking from the existing literature. We conclude by touching on emerging applications involving multiple-sensorial immersive media and provide suggestions for future research directions to fill existing gaps. It is hoped that this survey will be useful for researchers interested in building new immersive (adaptive) applications that maximize user experience.

“…(v) Heart rate monitor bracelet (see Figure 1(g)): for completeness, QoE should be monitored both using subjective, self-reported, measures, as well as objective ones. Of the latter, the most commonly used are physiological measures [44][45][46][47][48][49]. In this respect, in our study, we chose to monitor the participant's heart rate.…”

Intelligent mobile phones, or simply smartphones, have seen a large widespread usage among the entire world population during the last years. These devices are, in fact, considered as an essential tool in our current day to day life activities. Aromatherapy could be defined as the medical usage of essential oils derived from diverse types of vegetables. Although this paper does not look through direct medical usages or benefits, it is focused on one of its main effects, the stimuli to enhance focus. This study makes use of one of the main essential oils, rosemary, as olfactory stimuli over regular users performing a set of tasks with mobile apps. Results of the experimental group, when compared to regular users not affected with olfactory stimuli, aim to suggest that there is not a clear impact on mobile users’ performance. Nonetheless, more research is needed to categorize the effects of aromatherapy on mobile users.

“…The perceived QoE of multimedia applications is influenced by human, system, and context factors [36]. Therefore, understanding these factors is crucial to the success of a VR application [15]. For this reason, it is important to evaluate participants continuously while they are still performing the experiment's task.…”

“…As mentioned, VR is a powerful tool when it comes to simulate immersive audio-visual in the context of e-health applications. However, the evaluation of these technologies is crucial to increase the quality of experience (QoE) of the user [15]. QoE is related to the level of user satisfaction with an application or service [16].…”

Virtual reality (VR) has recently emerged as a platform that can be employed in the context of e-health applications. Even though the majority of VR-based applications focus on visual stimuli as the main content, audio also plays a very important role. If someone has an issue with auditory processing, the comprehension of auditory information is compromised. This condition reflects negatively on one's quality of life, given the impact of audio perception on one's ability to communicate effectively or to differentiate and ignore "noise". This work aims to design a VR application that can be used to: (a) optimize multimodal VR experiences based on user trials (b) extract user data continuously throughout the experiment (c) evaluate a user's auditory processing ability. To accomplish this goal, participants are required to localise a sound source in space in the presence of multiple listening conditions with simple and complex sound stimuli configurations. Data collected from users consists of physiological and objective metrics. The results of this study highlight the relationship between user behaviour (head movement, fixation points) and performance in the sound localisation task. This information can be used to design future applications with the purpose of training one's auditory localisation ability. In addition, the evaluation compared the impact of using two interaction methods to perform this task: using a pointer or eye gaze to indicate the location of the target source. The findings from this study show statistically significant differences in terms of physiological response when subjects are exposed to different interaction methods, with greater immersion and performance for the pointer group.
