COVID-19 pandemic has affected nearly every aspect of life. Observing online the spread of the virus can offer a complementary view to the cases that are daily officially recorded and reported. In this article, we present an approach that exploits information available on social media to predict whether a patient has been infected with COVID-19. Our approach is based on a Bayesian model that is trained using data collected online. Then the trained model can be used for evaluating the possibility that new patients are infected with COVID-19. The experimental evaluation presented shows the high quality of our approach. In addition, our model can be incrementally retrained, so that it becomes more robust in an efficient way.

**About**
 The PErvasive Technologies Related to Assistive Environments (PETRA) conference is a highly interdisciplinary conference that focuses on computational and engineering approaches to improve the quality of life and enhance human performance in a wide range of settings, in the workplace, at home, in public spaces, urban environments, and other. Outcomes of this conference have a broad impact in application areas that include, manufacturing, transportation, healthcare, energy systems, security and safety, robotics, biomedicine, environment and conservation, and many others. PETRA brings together very different types of technologies to also address important social and healthcare issues for sensitive populations, such as the elderly, persons suffering from chronic conditions such as Alzheimer’s, Parkinson’s, Cerebral Palsy, and other disabilities or traumas.

 PETRA (which means “stone” in Greek) addresses important human living needs. From a technological perspective, PETRA motivates and inspires new scientific thrusts, innovations and discoveries to improve living environments, a particularly important issue, in an increasingly crowded and complex world where the need for inclusiveness and connectivity with the rest of the world is key. For the elderly in particular, PETRA addresses the fact that, as people grow older; they will increasingly rely on technology to be able to prolong staying in their homes and enjoy an independent life.

 The PETRA 2021 proceedings will be published in the ACM Digital Library as part of the ACM ICPS program. The ISBN number assigned to PETRA '21 is 978-1-4503-8792-7

Nurses have to carry out a myriad of tasks, which is one of the main reasons for burnout. In this paper, a robotic Multitasking Intelligent Nurse Aid (MINA) is proposed to assist nurses with everyday tasks and tackle nurse burnout. MINA uses Simultaneous Localization And Mapping (SLAM) to map shelves in a storage room and pointcloud using an RGB-Depth camera. The barcode of the item is first detected using zbar library, and then the pointcloud is generated in ROS and saved accordingly. Preliminary experiments with respect to the creation of a pointcloud map with barcode detection are presented. The preliminary results reveal that the system shows a 100% barcode detection rate, and with each barcode detection a corresponding pointcloud map is generated and saved automatically without any intervention.

Assessment and prevention of work-related musculo-skeletal disorders (WMSD) and fatigue are considered common and critical tasks towards occupational safety and well-being in working environments. Indicators/risk factors for WMSD and physical/mental fatigue in the manufacturing industry include labor-intensive assembly works, repetitive tasks, prolonged, sub-optimal working postures and more. We briefly present our work on automatic, non-obtrusive detection of worker physical strain using visual data acquired by cameras and on automatic detection of worker fatigue based on heart rate (HR) data acquired by smartwatches.

We develop deep learning-based classifiers for Audio Event Detec-tion (AED), attacking them next with some white noise disturbances. We show that an attacker can use such simple disturbances to poten-tially fully avoid detection by AED systems. Prior work has shown that attackers can mislead image classification tasks, however this work focuses on attacks against AED systems, by tampering the audio and not image. This work brings awareness to the designers and manufacturers of AED systems and devices, as these solutions are becoming more ubiquitous by the day.

Manifolk is a tool to visualize the output of dimensionality reduction algorithms like t-SNE, PCA etc. One of this tool's main uses is that it de-clutters graphs by plotting data points pertaining to a subset of labels. The subset of labels to be plotted can be selected using the provided checkboxes. A case study on data from a publicly available action recognition dataset like UCF101 shows how this tool can help find outliers. With the rise in self-supervised methods for training deep neural networks, this tool helps researchers better visualize the embeddings learned by the model.

"This paper showcases a developed end-user framework for a human-robot collaborative system for common tasks, such as pick and
place. The system is designed for semi-automated pick and place
tasks as well as manual operation making it flexible for multiple
use-case scenarios. The goal of the system is to make the robot
multi-functional, easy to use with a graphical user interface and
to perform common tasks with the help of a human teammate.
Integration with object recognition neural network (YoloV3) and
an RGB-Depth camera helps automate pick and place tasks with a
wide variety of objects"

Difficulties with appropriate access to public or semi-public toilets for older or disabled people lead to less participation in social activities within this group. We present a smart AI-based toilet concept that uses 3D depth data to automatically pre-configure the height and tilt of a motorized toilet seat to support standing-up and sitting down without the necessity of user interaction. This has the potential to lead to increased autonomy and quality of life.

According to the CDC, COVID-19 most commonly spreads during close contact. Although the cleaners are disinfecting the public places where they are expected to have been contacted, it is still difficult to know exactly which areas have been touched and wiped out. We devised combined methods of detecting touched and wiped areas by people, using both thermal and imaging cameras. It detects the changes of temperature when people touched or wiped in about 3 seconds. To improve the accuracy, we utilize object recognition for humans from imaging cameras as a method of filtering. All marks are tracked and calculated, to disclose which areas are still remaining as touched areas, revealing the information to anyone who wants to know.

Methods of identifying touched areas have been wiped properly

Due to COVID-19, online gaming has grown, and in turn, ""toxicity” and cyberbullying have risen. Exhibiting toxicity can impact mood and relationships continuing into post-gaming
sessions. Moreover, experiencing constant harassment from toxic players can lead to depression in others. About 50 million gamers in the United States are kids under the age of 18,
and on these gaming platforms, there are over 150 million adults potentially influencing younger gamers with explicit language and behaviors. One of the greatest problems is that
gamers struggle with self-monitoring and recognizing their state of mind. To combat this issue, Tempr provides a unique approach through self-awareness and positive reinforcement to
help decrease verbal aggression and cyberbullying over time.

The amount of people living in severely hazardous air quality conditions is rapidly increasing due to climate change, wildfires and pollution. Many affected people can not afford air purifiers to protect themselves and those that can are unaware of when is the optimal time to activate theirs. In response to these issues, we create an affordable air purifier that alerts users when the optimal time is to activate their filters and is universally accessible.
