Advanced Mixed Reality Technologies for Surveillance and Risk Prevention Applications
We present a system that exploits advanced Mixed and Virtual Reality technologies to create a surveillance and security system that could be also extended to define emergency prevention plans in crowdy environments. Surveillance cameras are carried by a mini Blimp which is tele-operated using an innovative Virtual Reality interface with haptic feedback. An interactive control room (CAVE) receives multiple video streams from airborne and fixed cameras. Eye tracking technology allows for turning the user’s gaze into the main interaction mechanism; the user in charge can examine, zoom and select specific views by looking at them. Video streams selected at the control room can be redirected to agents equipped with a PDA. On-field agents can examine the video sent by the control center and locate the actual position of the airborne cameras in aGPS-driven map. The aerial video would be augmented with real-time 3D crowd to create more realist risk and emergency prevention plans. The prototype we present shows the added value of integrating AR/VR technologies into a complex application and opens up several research directions in the areas of tele-operation, Multimodal Interfaces, simulation, risk and emergency prevention plans, etc

"Mobile Applications for the Implementation of Health Control against Covid-19 in Educational Centers, a Systematic Review of the Literature"
"A health crisis caused by the SARS-CoV-2 virus is
still ongoing. That is why an important factor for the resumption
of on-site classes is the creation of sanitary measures to help
control Covid-19. The present research is a literature review, The
PRISMA methodology is used and 265 articles are collected from
various databases such as EBSCO Host, IEEE Xplore, SAGE,

were identified, systematizing 119 articles. Showcasing digital
technologies used in mobile applications that allow better control,
tracking, and monitoring of the health status of students,
teachers, and staff of educational centers, in addition to the
parameters and quality attributes that must be taken into
account for the effective sanitary control of the disease, finally, a
development model is proposed.

A survey on robotic technologies for forest firefighting: Applying drone swarms to improve firefighters’ efficiency and safety
Forest firefighting missions encompass multiple tasks related to prevention, surveillance, and extinguishing. This work presents a complete survey of firefighters on the current problems in their work and the potential technological solutions. Additionally, it reviews the efforts performed by the academy and industry to apply different types of robots in the context of firefighting missions. Finally, all this information is used to propose a concept of operation for the comprehensive application of drone swarms in firefighting. The proposed system is a fleet of quadcopters that individually are only able to visit waypoints and use payloads, but collectively can perform tasks of surveillance, mapping, monitoring, etc. Three operator roles are defined, each one with different access to information and functions in the mission: Mission commander, team leaders, and team members. These operators take advantage of virtual and augmented reality interfaces to intuitively get the information of the scenario and, in the case of the mission commander, control the drone swarmThis research received no external fundin
The Visual Social Distancing Problem
One of the main and most effective measures to contain the recent viral
outbreak is the maintenance of the so-called Social Distancing (SD). To comply
with this constraint, workplaces, public institutions, transports and schools
will likely adopt restrictions over the minimum inter-personal distance between
people. Given this actual scenario, it is crucial to massively measure the
compliance to such physical constraint in our life, in order to figure out the
reasons of the possible breaks of such distance limitations, and understand if
this implies a possible threat given the scene context. All of this, complying
with privacy policies and making the measurement acceptable. To this end, we
introduce the Visual Social Distancing (VSD) problem, defined as the automatic
estimation of the inter-personal distance from an image, and the
characterization of the related people aggregations. VSD is pivotal for a
non-invasive analysis to whether people comply with the SD restriction, and to
provide statistics about the level of safety of specific areas whenever this
constraint is violated. We then discuss how VSD relates with previous
literature in Social Signal Processing and indicate which existing Computer
Vision methods can be used to manage such problem. We conclude with future
challenges related to the effectiveness of VSD systems, ethical implications
and future application scenarios.Comment: 9 pages, 5 figures. All the authors equally contributed to this
