Natural language processing and the machine translation of spoken language (speech/text) has benefitted from significant scientific research and development in recent times, rapidly advancing the field. On the other hand, computational processing and modelling of signed language has unfortunately not garnered nearly as much interest, with sign languages generally being excluded from modern language technologies. Many deaf and hard-of-hearing individuals use sign language on a daily basis as their first language. For the estimated 72 million deaf people in the world, the exclusion of sign languages from modern natural language processing and machine translation technology, aggravates further the communication barrier that already exists for deaf and hard-of-hearing individuals. This research leverages a linguistically informed approach to the processing and modelling of signed language. We outline current challenges for sign language machine translation from both a linguistic and a technical prespective. We provide an account of our work in progress in the development of sign language lexicon entries and sign language lexeme repository entries for SLMT. We leverage Role and Reference Grammar together with the Sign_A computational framework within this development. We provide an XML description for Sign_A, which is utilised to document SL lexicon entries together with SL lexeme repository entries. This XML description is also leveraged in the development of an extension to Bahavioural Markup Language, which will be used within this development to link the divide between the sign language lexicon and the avatar animation interface. © AMTA 2022 - 15th Conference of the Association for Machine Translation in the Americas, Proceedings.

Virtual humans play a pivotal role in social virtual environments, shaping users' VR experiences. The diversity in available options and users' individual preferences can result in a heterogeneous mix of appearances among a group of virtual humans. The resulting variety in higher-order anthropomorphic and realistic cues introduces multiple (in)congruencies, eventually impacting the plausibility of the experience. However, related work investigating the effects of being co-located with multiple virtual humans of different appearances remains limited. In this work, we consider the impact of (in)congruencies in the realism of a group of virtual humans, including co-located others (agents) and one's self-representation (self-avatar), on users' individual VR experiences. In a 2×3 mixed design, participants embodied either (1) a personalized realistic or (2) a customized stylized self-avatar across three consecutive VR exposures in which they were accompanied by a group of virtual others being either (1) all realistic, (2) all stylized, or (3) mixed between stylized and realistic. Our results indicate groups of virtual others of higher realism, i.e., potentially more congruent with participants' real-world experiences and expectations, were considered more human-like, increasing the feeling of co-presence and the impression of interaction possibilities. (In)congruencies concerning the homogeneity of the group did not cause considerable effects. Furthermore, our results indicate that a self-avatar's congruence with the participant's real-world experiences concerning their own physical body yielded notable benefits for virtual body ownership and self-identification for realistic personalized avatars. Notably, the incongruence between a stylized self-avatar and a group of realistic virtual others resulted in diminished ratings of self-location and self-identification. This suggests that higher-order (in)congruent visual cues that are not within the ego-central referential fr

This paper presents the development of an anthropomorphic robot designed for collaborative research alongside the Kuka LBR iiwa R820 robotic arm for the research project I-CATER. The primary objectives were designing a robust and stable robot's structure, integrating hardware using the Robot Operating System (ROS), and developing a user- friendly human-Machine Interface. Priority was set on ensuring the structure could support two robotic arms without compromising stability or functionality. Key components include 7 Degrees of Freedom (DoF) robotic arms, Rg2 grippers, a display and a 2 DoF neck for the vision system support, resembling the human head configuration. Considerations such as size, cost, fabrication techniques, and material availability were taken into account in the structure's design. Integration into a simplified interface allows for easy manipulation without advanced programming knowledge, facilitated by the middleware ROS for modularity and future upgrades. The outcome is RAMBO - a Robotic Anthropomorphic Manipulator for Bimanual Operations - which is a valuable research platform for natural human-robot collaboration.

Obesity is a serious disease that can affect both physical and psychological well-being. Due to weight stigmatization, many affected individuals suffer from body image disturbances whereby they perceive their body in a distorted way, evaluate it negatively, or neglect it. Beyond established interventions such as mirror exposure, recent advancements aim to complement body image treatments by the embodiment of visually altered virtual bodies in virtual reality (VR). We present a high-fidelity prototype of an advanced VR system that allows users to embody a rapidly generated personalized, photorealistic avatar and to realistically modulate its body weight in real-time within a carefully designed virtual environment. In a formative multi-method approach, a total of 12 participants rated the general user experience (UX) of our system during body scan and VR experience using semi-structured qualitative interviews and multiple quantitative UX measures. By using body weight modification tasks, we further compared three different interaction methods for real-time body weight modification and measured our system’s impact on the body image relevant measures body awareness and body weight perception. From the feedback received, demonstrating an already solid UX of our overall system and providing constructive input for further improvement, we derived a set of design guidelines to guide future development and evaluation processes of systems supporting body image interventions. © 2022, CC BY.

The paper attempts to offer a method to consistently monitor and capture a data eco-system in the everyday of a patient-caregiver relationship. We offer an account of the capture and intermeshing of different types and quality of data sources and their gainful deflection into a methodological protocol for ethnographic engagements. We call this the ‘360° feedback’ ethnography and elaborate its underlying methodological process in this paper. Building on the live feedback obtained from various stakeholder activities in a care ecosystem, we propose how a 360° feedback can enrich regenerative knowledge.

Sociologist at IBM Research – Almaden where he examines work practice social interaction and human-computer interaction.

Trends of independent workers, an economy of increasingly automated processes and an ethos of the peer-to-peer “sharing economy” are all coming together to transform work and employment as we know them. Emerging forms of “open” and “crowd” work are particularly keen sites for investigating how the structures and experiences of work, employment and organizations are changing. Drawing on research and design of work in organizational contexts, this paper explores how experiences with open and crowd work systems serve as sites of workplace cultural re-imagining. A marketplace, a crowdwork system and a crowdfunding experiment, all implemented within IBM, are examined as instances of new workplace configurations.

EDITOR'S SUMMARY Makerspaces are environments where crafters and techies can come together to create, share and learn. Many libraries support the maker movement by providing access to a variety of technologies from sewing machines and looms to recording equipment and production tools, an expansion of services that is in line with promoting literacy, community and lifelong learning. About one third of makerspaces charged a fee or required membership in 2013, though some, including libraries and museums, are supported by major funding agencies. Digital fabrication technology or 3D printers are increasingly available through library-based makerspaces and extend opportunities for STEM education, but libraries face challenges from high initial and ongoing costs, user training and even encouraging users in 3D thinking and design. 3D printers can be a powerful stimulus for creativity, learning and sharing, even promoting jobs and community development.

This paper presents the design and evaluation of ProFi, a PROduct FInding assistant in a supermarket scenario. We explore the idea of micro-navigation in supermarkets and aim at enhancing visual search processes in front of a shelf. In order to assess the concept, a prototype is built combining visual recognition techniques with an Augmented Reality interface. Two AR patterns (circle and spotlight) are designed to highlight target products. The prototype is formally evaluated in a controlled environment. Quantitative and qualitative data is collected to evaluate the usability and user preference. The results show that ProFi significantly improves the users' product finding performance, especially when using the circle pattern, and that ProFi is well accepted by users. Copyright © 2013 ACM.
