**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

The world’s population is ageing rapidly while cognitive impairment in older ages is more evident than ever. Hence, the health and wellbeing among the elderly is an issue of paramount importance. The speedy growth of technology and its application within healthcare has advanced computerized cognitive interventions, which aim to delay the onset and potential progression of cognitive decline. Consequently, the traditional cognitive interventions have made a swift to novel multimedia systems to promote independent, active and healthy ageing. The primary objective of the present study is to introduce an innovative computerized cognitive gamified training and social activation program for health and mildly cognitive impaired older adults. The platform is designed as an extension and adaptation of a previous computerized cognitive training program called ‘SOCIABLE’. Evaluation of the newly designed platform through a single-arm feasibility study followed by a full randomized double-blind controlled trial is recommended as future steps for this piece of work.

A highly user-centered design approach for developing a mobile health app for pain management (PainApp)

Over the course of the coming decades, the societal goal of maximizing the number of older adults who experience positive trajectories of ageing has been established. To this end, innovative technologybased interventions tailored to older adults’ functional levels and focused on healthy lifestyles are considered imperative. The purpose of this work is to present a cluster of digital solutions aims at supporting and maintaining healthy and independent living for older adults, who face permanently or temporarily reduced functionality and capabilities.

Assistive Technologies for Supporting Wellbeing of Older Adults

Inferring the emotional state of an individual by viewing his/her facial expression seems to be present in all human cultures. Numerous
studies have shown that various changes in facial muscles determine the resulting facial expression. The analysis of images of faces
expressing emotional states promises to contribute to the quantification
of the claimed observations. Here, we use a suite of AI (artificial
intelligence) algorithms, along with ML (maximum likelihood) estimated distributions to quantify the shift in facial expression from
“neutral”→“fear” and “pain”→“pleasure”. The images are single
frames of five emotional states (neutral, fear, pain, pleasure, laugh)
expressed by actors and actresses in BDSM videos. We extract a feature vector for each image, dimension-reduce these feature vectors
by mapping them onto a two-dimensional manifold and calculate
the norms of the normalized displacement vectors for each emotional pair. We then find that the ML distributions of the norms are
Gamma-distributed and that the modes for each pair are different
for both males and females. We use Wilks lambda to determine
significance. We find that the distributions for the females are significantly different, but not for the males. The methodology we present
here has widespread applications: monitoring the emotional states
of humans in various settings; among these: determining whether
participants in BDSM and similar videos are indeed volunteering
their participation or are victims of criminal activity.

Visual Analysis of Emotions Using AI Image-Processing Software: Possible Male/Female Differences between the Emotion Pairs “Neutral”–“Fear” and “Pleasure”–“Pain”

As the field of robotics develops, so do the methods of interfacing with and controlling those robots. Many modern robots can be communicated with using commands that require neither speech nor touch. The two main motivations behind this trend are the assistance of people with disabilities and the desire for more natural Human-Robot Interaction (HRI). In allowing nonverbal communication with robots, accessibility of the systems increases to allow more people to interact with and benefit from robotics systems. Additionally, nonverbal communication provides more natural communication, which can lead to many benefits in HRI. This paper
provides an overview of existing technologies in touchless and nonverbal human-robot interfaces; it presents the most prevalent interface methods, their uses, and limitations. Discussions are provided on future directions for research.

Interfacing with Robots without the use of Touch or Speech

Force control is nowadays a mature technology and it is becoming more and more common in severed robotic applications. Despite this, an effective standardized and comprehensive method to assess force control performance does not exist. Defining the performance of a force-controlled system is not a trivial task, and one of the reason is that performance does not only depend on the dynamics of the robot, but also on the dynamics of the environment, which are usually uncertain and time-varying. Exerting a force on a soft environment is different from exerting a force on a rigid environment. Indeed, the same force-controlled robot can have different force responses in different environments. This paper proposes a methodology to standardize the benchmarking of force control algorithms applied to different actuation architectures and considering a wide set of possible environments and disturbances, defined by the application of interest.

Automatic building extraction from satellite RGB images, is a low-cost alternative to perform important urban planning tasks. Yet, itis a challenging one, especially when natural and non-city block objects interfere in the semantic segmentation of algorithms that extract their key features. In this work we approach the automatic building extraction using a Convolution Neural Network based on the U-Net architecture. In contrast to existing approaches, it successfully encodes important features and decodes the buildings’ localization by requiring both reduced computational time and dataset size. We evaluate the U-Net’s performance using RGB images selected from the SpaceNet 1 dataset and the experimental results show an accuracy in building localization of 92.3%. Finally,favorable comparison with existing CNN approaches to hyper-spectral images targeting the SpaceNet 1 dataset, demonstrated its effectiveness.

The presentation provides a novel method for reducing a multi-class Confusion Matrix into a 2 × 2 version enabling the use of the relevant performance metrics and methods like the Receiver Operating Characteristic and the Area Under the Curve for the assessment of different classification algorithms. The reduction method is based on class grouping and leads to a specific Confusion Matrix format. The developed method is then exploited for the assessment of several state-of-the-art machine learning algorithms applied on a customer experience metric called Net Promoter Score (NPS).

Man overboard incidents in a maritime vessel are serious accidents where, the efficient and rapid detection is crucial in the recovery of the victim. The severity of such accidents, urge the use of intelligent systems that are able to automatically detect a fall and provide relevant alerts. To this end the use of novel deep learning and computer vision algorithms have been tested and proved efficient in problems with similar structure. This paper presents the use of a deep learning framework for automatic detection of man overboard incidents. We investigate the use of simple RGB video streams for extracting specific properties of the scene, such as movement and saliency, and use convolutional spatiotemporal autoencoders to model the normal conditions and identify anomalies. Moreover, in this work we present a dataset that was created to train and test the efficacy of our approach.
