ABSTRACT

The strict confinement phase decreed by the Government to deal with the Covid-19 pandemic represented an exponential increase in the granting of holographic wills due to the impossibility of citizens to go to a notarial office. Once the deceased passed away, the holder or depositary will have ten days counting from the day after they had news of the death to present the will before a competent notary so that it can be confirmed. This work studies what consequences are derived from not respecting said legal mandate, with special attention to the civil liability that the infringer may incur, as well as the extent to which it can be considered unworthy to succeed whoever had willfully breached the provisions of the sec. 690 of the Spanish Civil Code. © 2022 Ibero-American Law Institute.

ABSTRACT

Lensless holographic microscopy (LHM) comes out as a promising label-free technique since it supplies high-quality imaging and adaptive magnification in a lens-free, compact and cost-effective way. Compact sizes and reduced prices of LHMs make them a perfect instrument for point-of-care diagnosis and increase their usability in limited-resource laboratories, remote areas, and poor countries. LHM can provide excellent intensity and phase imaging when the twin image is removed. In that sense, multi-illumination single-holographic-exposure lensless Fresnel (MISHELF) microscopy appears as a single-shot and phase-retrieved imaging technique employing multiple illumination/detection channels and a fast-iterative phase-retrieval algorithm. In this contribution, we review MISHELF microscopy through the description of the principles, the analysis of the performance, the presentation of the microscope prototypes and the inclusion of the main biomedical applications reported so far.

ABSTRACT

Globally new pandemic diseases induce urgent demands for portable diagnostic systems to prevent and control infectious diseases. Smartphone-based portable diagnostic devices are significantly efficient tools to user-friendly connect personalized health conditions and collect valuable optical information for rapid diagnosis and biomedical research through at-home screening. Deep learning algorithms for portable microscopes also help to enhance diagnostic accuracy by reducing the imaging resolution gap between benchtop and portable microscopes. This review highlighted recent progress and continued efforts in a smartphone-tethered optical platform through portable, automated, and deep-learning-enabled microscopy for personalized diagnostics and remote monitoring. In detail, the optical platforms through smartphone-based microscopes and lens-free holographic microscopy are introduced, and deep learning-based portable microscopic imaging is explained to improve the image resolution and accuracy of diagnostics. The challenges and prospects of portable optical systems with microfluidic channels and a compact microscope to screen COVID-19 in the current pandemic are also discussed. It has been believed that this review offers a novel guide for rapid diagnosis, biomedical imaging, and digital healthcare with low cost and portability.

ABSTRACT

Public displays are some of the most challenging interfaces to design because of two key characteristics. First, the experience should be engaging, to attract and maintain users' attention. Second, the interaction with the display should be natural, meaning that users should be able to receive the desired output with little or no training. Holographic displays are increasingly popular in public spaces such as museums and concert halls but there is little published research on users' experiences with such displays. Previous research has suggested both tangible and intangible inputs as engaging and natural options for holographic displays, but there is no conclusive evidence on their relative merits. Hence, we run a study to investigate the user experience with a holographic display comparing the level of engagement and feeling of natural experience in the interacting process. We used a mix of surveys, interviews, video recordings, and task-based metrics to measure users' performance on a specific task, the perceived usability, and levels of engagement and satisfaction. Our findings suggest that a tangible input was reported as more natural than the intangible one, however, both tangible and intangible inputs were found to be equally engaging. The latter findings contribute to the efforts of designing intangible public holographic displays and other interactive systems that take into consideration health safety issues, especially during the Covid-19 pandemic era in which contamination can be established with tangible and physical interaction between users and public displays, yet without affecting the level of engagement compared to the tangible experience. © 2022 IEEE.

ABSTRACT

Fueled by advances in multi-party communications, increasingly mature immersive technologies being adopted, and the COVID-19 pandemic, a new wave of social virtual reality (VR) platforms have emerged to support socialization, interaction, and collaboration among multiple remote users who are integrated into shared virtual environments. Social VR aims to increase levels of (co-)presence and interaction quality by overcoming the limitations of 2D windowed representations in traditional multi-party video conferencing tools, although most existing solutions rely on 3D avatars to represent users. This article presents a social VR platform that supports real-time volumetric holographic representations of users that are based on point clouds captured by off-the-shelf RGB-D sensors, and it analyzes the platform's potential for conducting interactive holomeeting scenarios (i.e., holoconferencing sessions for remote gathering and formal discussion). This work evaluates such a platform's performance and readiness for conducting holomeetings with up to four users, and it provides insights into aspects of the user experience when using single-camera and low-cost capture systems in scenarios with both frontal and side viewpoints. Overall, the obtained results confirm the platform's maturity and the potential of holographic communications for conducting interactive multi-party meetings, even when using low-cost systems and single-camera capture systems in scenarios where users are sitting or have a limited translational movement along the X, Y, and Z axes within the 3D virtual environment (commonly known as 3 Degrees of Freedom plus, 3DoF+).

ABSTRACT

In order to face the requirement of distant education after covid-19, this paper has presented a cyber-physical co-existence environment for practical distance learning events, we called it as a “Co-existing Practical Environment, CPE”. CPE includes: “Holographic Wearable Device, HWD” for behavior sensing and vision sharing mechanism, cloud “Digital Twin Model, DTM” database for expert correcting variables real time, and collaborative fabrication discussion interface. We built an immersive HoloLens interface to help distance learning participators, understanding the concept of structural mechanics form morphs with mix-reality sensing, communicating the augmented information of parts of models for collaborative fabrication, and sharing the views of operation process for lecturers to solve the technical problems instantly. Furthermore, users are able to make their own custom digital twin project in CPE and optimize their fabricating process by adding more realistic material factors, operation callbacks, or analyzing their practice results in parameters relationships. This paper revised an application of holographic technology with a practical distance learning workshop as example, and discover CPE as a new kind of co-creation, cross-field, and remotely prepared cooperation mechanism. While the epidemic is still ragging, we are looking further researchers of more immersive methods for distance education. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

COVID has raised the awareness of hygiene significantly. Touching surfaces should be avoided but many devices in daily life and public spaces require direct contact. We report on touchless user interfaces to overcome these issues. Examples are elevator control, pedestrian lights and pin input at ATMs. Infrared proximity and position sensing replace pushbuttons, knobs etc. The numeric keypad of the ATM demonstrator is projected by a holographic plate in mid-air. So location of the numbers can be scrambled which makes skimming together with a small observer angle nearly impossible. © 2021 IEEE.

ABSTRACT

The Malaysian Education System have recently implemented the home-based teaching and learning or Pengajaran dan Pembelajaran di Rumah (PdPR) classes due to the outbreak of the pandemic COVID19. Since students were not able to go to schools during the lockdown period, teachers and parents have resorted to creating various methods to engage students in their learning process. Multi-touch technology on tablet appears as a promising tool in visual learning especially during this pandemic out-break. This paper presents a preliminary study conducted on a research project in developing a Visual Learning Application for Mathematics using Holographic Display for the topic on Shape and Space based on Multi-Touch Technology called MEL-VIS. A preliminary study was conducted on fifteen (15) primary school teachers. The results of the preliminary study showed that the topic on Shape and Space is a topic that most students had major problems when learning Mathematics at three (3) primary schools. Students were found to have difficulty in understanding the concepts being taught due to factors such as: ive phenomena and concepts;as well as possessing low imagination. © 2021, Springer Nature Switzerland AG.

ABSTRACT

This paper prosed a novel 6G QoS over the future 6G wireless architecture to offer excellent Quality of Service (QoS) for the next generation of digital TV beyond 2030. During the last 20 years, the way society used to watch and consume TV and Cinema has changed radically. The creation of the Over The Top content platforms based on Cloud Services followed by its commercial video consumption model, offering flexibility for subscribers such as n Video on Demand. Besides the new business model created, the network infrastructure and wireless technologies also permitted the streaming of high-quality TV and film formats such as High Definition, followed by the latest widespread TV standardization Ultra-High- Definition TV. Mobile Broadband services onset the possibility for consumers to watch TV or Video content anywhere at any time. However, the network infrastructure needs continuous improvement, primarily when crises, like the coronavirus disease (COVID-19) and the worldwide pandemic, creates immense network traffic congestions. The outcome of that congestion was the decrease of QoS for such multimedia services, impacting the user's experience. More power-hungry video applications are commencing to test the networks' resilience and future roadmap of 5G and Beyond 5G (B5G). For this, 6G architecture planning must be focused on offering the ultimate QoS for prosumers beyond 2030.
