RO-MAN 2021's theme is trustworthiness and cooperation. We chose this term well before the pandemic put the world on edge and added a new reason for us to question our own personal safety when in the company of others. But what about in the company of social robots? What would cause us to trust, or not trust, them? How do we as researchers create that feeling, that critical component of any relationship? With social robots, it is of course largely in our power to design the physical form, the control code and the interface software to maximize trustworthiness, facilitate cooperation and enhance the quality of human-robot interaction. This theme also touches upon people's expectations and perceptions of robots, as well as other social, cognitive and cultural factors that will influence human-robot interactions. We will have a special session/track on this topic, invite targeted submissions and include plenary speakers who are specialist in this area. We sincerely hope that this focus will help enlighten the design-thinking of all of us as we fabricate and program our own various systems.

**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

Teletherapeutic devices enable new possibilities to track the therapy process by gathering and visualizing training statistics. For the therapist this can mean a quicker but also a deeper look at the therapy results. For the patient, the right presentation of data can foster the motivation and adherence to the therapy. In an iterative user centered design process, requirements of data visualization were gathered and the developed solution was validated with health professionals. For the therapists, the most important part is to have a comprehensive overview of conducted exercises and training duration. For the patient, the visualization should be simple and motivative. Further validation, especially with patients is needed.

In this paper we present early results of a novel approach for human activity recognition, focusing on activities of daily living. Our approach is multimodal, i.e., it combines RGB, depth and skeletal data measurements. Moreover, it is based on a novel hybrid deep neural network architecture that combines a convolutional neural network, a long short term memory network and it is evaluated using a publicly available dataset.

The simulated environment presented aims to provide a method for preparing a training set for most of this deep network adaptation. The goal is to use a simulation-generated training set for most or all of the data needed to achieve the transfer of knowledge from the original network to the platform-specific

A Simulated Environment For Traversability Estimation Experiments In Field Robotic Applications

Virtual Reality (VR) is attracting more and more attention from academic research and practical application with the current availability of low-cost and end-user friendly devices. In terms of haptic (rather than visual) interaction, however, this technology is still in its infancy and there are few devices that are inexpensive and technologically simple to operate, respectively to procure. In this context, we present a concept of how haptic interaction with VR data gloves can also succeed by means of a commercially available web cam, sophisticated tracking software, and homemade low-cost hardware. All hardware and software components are to be obtained inexpensively or are open-source in order to achieve the greatest possible dissemination potential. With this work, we intend to provide an important trigger for future improvements and dissemination in terms of both technology and areas of application.

Sign language (SL) technologies including various deaf accessibility tools, dynamic sign language synthesis systems, machine learning based signing video recognition algorithms and sign language machine translation, are only some of the technologies requiring the existence of sign language annotated resources. SL resources are equally critical for the development of various end-user tools and services, which support everyday communication needs via SL.
The poster demonstrates how annotated SL lexical and corpus resources, created and maintained at ILSP/ATHENA RC, serve the needs of both Sign Language Technologies and Greek Sign Language (GSL) signers’ accessibility.

FutureMe: Negotiating Learning Goals with your Future Learning-Self Avatar

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.
