“…Through TI technologies and the more recent vision of digitalized immersive 3D realms known as Metaverse (e.g., Al-Ghaili et al, 2022;Mystakidis, 2022;Rostami and Maier, 2022), the embodiments of human perceptual and cognitive processes would frequently be interacting with digitalized multisensory signals including haptics. Such "digital embodiments" raise challenges for digitalizing sensory signals in ways that preserve key stimulus characteristics for humans to sense and perceive, while not overburdening the latency and capacity requirements on the telecommunication networks that transmit these signals (e.g., Steinbach et al, 2018;Noll et al, 2022).…”

Mechanisms underlying perceptual processing and inference undergo substantial changes across the lifespan. If utilized properly, technologies could support and buffer the relatively more limited neurocognitive functions in the still developing or aging brains. Over the past decade, a new type of digital communication infrastructure, known as the “Tactile Internet (TI),” is emerging in the fields of telecommunication, sensor and actuator technologies and machine learning. A key aim of the TI is to enable humans to experience and interact with remote and virtual environments through digitalized multimodal sensory signals that also include the haptic (tactile and kinesthetic) sense. Besides their applied focus, such technologies may offer new opportunities for the research tapping into mechanisms of digitally embodied perception and cognition as well as how they may differ across age cohorts. However, there are challenges in translating empirical findings and theories about neurocognitive mechanisms of perception and lifespan development into the day-to-day practices of engineering research and technological development. On the one hand, the capacity and efficiency of digital communication are affected by signal transmission noise according to Shannon’s (1949) Information Theory. On the other hand, neurotransmitters, which have been postulated as means that regulate the signal-to-noise ratio of neural information processing (e.g., Servan-Schreiber et al., 1990), decline substantially during aging. Thus, here we highlight neuronal gain control of perceptual processing and perceptual inference to illustrate potential interfaces for developing age-adjusted technologies to enable plausible multisensory digital embodiments for perceptual and cognitive interactions in remote or virtual environments.

“…HMDs are widely considered the default hardware equipment to experience metaverse applications. HMD is a convenient replacement for the conventional smartphone in terms of visual experience, which brings the smartphone UI right in front of our eyes [2]. There are three types of HMDs that can be used in DWS depending on the target application, namely, nonsee-through (NST-HMD), optical see-through (OST-HMD) and video see-through (VST-HMD) [1].…”

“…HMDs open a wide scope of applications, which allow users to experience an immersive full size view of the scenery, which has been previously hidden behind the small flat screen of the conventional smartphone. In addition, the extended reality (XR) based on AR and VR solutions allows one to merge physical and virtual worlds and interact with physical and virtual things altogether [2].…”

“…Whereas HMDs can easily compete with conventional smartphones in terms of visual and audio experience, there is still a need for a convenient solution that can replace the commonly used touch screens and buttons. To actually "dive into the metaverse", the HMD should be synchronized with supplementary devices, which can augment the spatial orientation of the user, gestures, virtual touches, etc [2].…”

<p>The goal of the metaverse is to provide a synchronized interoperability of real and virtual worlds across multiple domains and applications. The main challenge is to make the metaverse interface both immersive and responsive to user actions. In this paper, we propose a new concept called a distributed wearable smartphone, which provides a synergistic integration of head-mounted displays, wearable sensors and other smart devices to translate user context and actions across real and virtual metaverse domains. The proposed architecture is flexible and can be composed from any set of devices, depending on the target application. The key benefits of the proposed approach are the realistic 3D representation and the semi-virtual user experience, which can be extended to a wide range of different applications in industry, education, healthcare and entertainment.</p>

In 5th generation (5G) and Beyond 5G mobile communication systems, it is expected that numerous antennas will be densely deployed to realize ultra-broadband communication and uniform coverage. However, as the number of antennas increases, total power consumption of all antennas will also increase, which leads to a negative impact on the environment and operating costs of telecommunication operators. Thus, it is necessary to simplify an antenna structure to suppress the power consumption of each antenna. On the other hand, as a way to realize ultra-broadband communication, millimeter waves will be utilized because they can transmit signals with a broader bandwidth than lower frequencies. However, since millimeter waves have a large propagation loss, a propagation distance is shorter than that of low frequencies. Therefore, in order to extend the propagation distance, it is necessary to increase an equivalent isotropic radiated power by beamforming with phased array antenna. In this paper, a phased antenna array module in combined with analog radio over fiber (A-RoF) technology for 40-GHz millimeter wave is developed and evaluated for the first time. An 8 × 8 phased array antenna for 40-GHz millimeter wave with integrated photodiodes and RF chains has been developed, and end-to-end transmission experiment including 20 km A-RoF transmission and 3-m over-the-air transmission from the developed phased array antenna has been conducted. The results showed that the 40-GHz RF signal after the end-to-end transmission satisfied the criteria of 3GPP signal quality requirements within ±50 degrees of main beam direction.
