This paper presents a CNN-based network architecture aimed to classify and detect joint types within Articulated objects, specifically the Push-P joints, P-joints, R-joints and objects lacking joints. The movement modeling of the detected objects is explored by processing pre and post interaction RGB images within the SAPIEN PartNet-Mobility dataset. In order to achieve this, an architecture is proposed to leverage consecutive CNN encoders based on the VGG architecture, in order to classify joints based on pre and post-interaction images. Additionally, in order to detect the effect-point and movement vector, a convolutional encoder is applied for each joint type. Moreover, extensive evaluation is made to showcase the results, achieving 96% accuracy in joint classification and 94% accuracy in regression on the considered dataset. Elaborate details regarding network architectures, training procedures, and testing methodologies are available at source code repository.

Each lexical expression in a language has its own history: elements of a language are the result of several linguistic processes and may descend from expressions of other languages. In this paper, we propose an ontology to represent linguistic phenomena, in particular those that have changed over time the pronunciation or morphology of lexical elements. Then, this ontology is applied to the study of some Gallo-Italic varieties spoken in Sicily. In more details, the linguistic phenomena that have generated the lexical expressions in these languages from Latin etymons have been encoded with our ontology. In addition, an operational actionable description, based on regular expressions, has been provided for a relevant amount of these phenomena. © 2024 Copyright for this paper by its authors.

Exergaming, blending exercise and gaming, improves the physical and mental health of older adults. We currently do not fully know the factors that drive older adults to either engage in or abstain from exergaming. Large-scale studies investigating this are still scarce, particularly those studying East Asian older adults. To address this, we interviewed 64 older adults from China, Japan, and South Korea about their attitudes toward exergames. Most participants viewed exergames with a positive inquisitiveness. However, socio-cultural factors can obstruct this curiosity. Our study shows that perceptions of aging, lifestyle, the presence of support networks, and the cultural relevance of game mechanics are the crucial factors influencing their exergame engagement. Thus, we stress the value of socio-cultural sensitivity in game design and urge the HCI community to adopt more diverse design practices. We provide several design suggestions for creating more culturally approachable exergames. © 2024 Owner/Author.

This paper introduces a pioneering experimental study on the automated packing of a catering package using a two-fingered gripper affixed to a 3-degree-of-freedom Delta parallel robot. A distinctive contribution lies in the application of a deep learning approach to tackle this challenge. A custom dataset, comprising 1,500 images, is meticulously curated for this endeavor, representing a noteworthy initiative as the first dataset focusing on Persian-manufactured products. The study employs the YOLOV5 model for object detection, followed by segmentation using the FastSAM model. Subsequently, rotation angle calculation is facilitated with segmentation masks, and a rotated rectangle encapsulating the object is generated. This rectangle forms the basis for calculating two grasp points using a novel geometrical approach involving eigenvectors. An extensive experimental study validates the proposed model, where all pertinent information is seamlessly transmitted to the 3-DOF Delta parallel robot. The proposed algorithm ensures real-time detection, calibration, and the fully autonomous packing process of a catering package, boasting an impressive over 80% success rate in automatic grasping. This study marks a significant stride in advancing the capabilities of robotic systems for practical applications in packaging automation.

Teacher-centric educational recommender systems in K12 practice: Usage and evaluation

Personalized learning is hard to apply in classroom practice due to the workload of teachers. Recommender systems can help teachers make choices and hence personalize the learning environment. However, few studies have investigated how teachers use recommender systems in their practice. Educational recommender systems also require more investigation into how teachers assess recommendations to provide better systems in the future. Therefore, this research aimed to provide a better insight into the practical application of a teacher-centric educational recommender system, conduct a user-centric evaluation of the recommender system, and present teacher beliefs on the use of educational recommender systems for personalized learning. Our results indicated that teachers similarly used the recommender system by creating new lessons rather than adapting suggested lessons. Their evaluations of the recommender system highlighted the importance of accuracy and utility. Diversity and serendipity were considered to be less important. Teachers perceived recommender systems as a first step to personalized learning and as a tool for simplifying such learning. However, the current system did not affect the quality of personalized learning. Based on these results, we propose to focus more on accuracy and utility as opposed to diversity and serendipity for teacher-centric recommender system evaluation. For personalized learning, we conclude that, according to teachers, recommender systems can lead to more effective personalization by allowing teachers to focus on student needs. © 2025 The Authors

People are increasingly eager to know more about themselves through technology. To date, technology has primarily provided information on our physiology. Yet, with advances in wearable technology and artificial intelligence, the current advent of consumer neurotechnology will enable users to measure their cognitive activity. We see an opportunity for research in human-computer interaction (HCI) in the development of these devices. Neurotechnology offers new insights into user experiences and facilitates the development of novel methods in HCI. Researchers will be able to create innovative interactive systems based on the ability to measure cognitive activity at scale in real-world settings. In this paper, we contribute a vision of how neurotechnology will transform HCI research and practice. We discuss how neurotechnology prompts a discussion about ethics, privacy, and trust. This trend highlights HCI's crucial role in ensuring that neurotechnology is developed and utilised in ways that truly benefit people. © 2024 the author(s), published by De Gruyter, Berlin/Boston.

Currently, the shortage of personnel and the increasing proportions of older individuals in need of care pose enormous challenges to care facilities. Some of the resulting hospitalizations in nursing home are not medically necessary for geriatric patients and can even cause a deterioration of their health. Using telemedical consultations in nursing homes represents one approach aiming at the reduction of unnecessary hospitalizations of geriatric patients and support of care personnel in acute and uncertain situations. Hence, the patients’ as well as the care personnel’s perspectives and their acceptance are essential for a successful implementation of these telemedical consultations. This paper presents qualitative and quantitative results of acceptance patterns in using telemedical consultations from a social communication science perspective within the Optimal@NRW project. An initial qualitative interview study with residents and care personnel of different nursing homes (N = 28) identified attitudes, perceived advantages, and concerns as well as requirements regarding the usage of telemedical consultations. These results provided the basis for further quantifications and for the comparison of acceptance parameters of using telemedical consultations in nursing homes across the entire duration of the project. In a second step, we present the results of a first quantitative study (N = 145) that quantified and validated the previously identified qualitative parameters. Insights of the current empirical approach should be considered within the conceptualization and implementation of telemedical services in nursing homes to fulfill the needs of the respective users, in particular geriatric patients and their care personnel. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Person image synthesis with controllable body poses and appearances is an essential task owing to the practical needs in the context of virtual try-on, image editing and video production. However, existing methods face significant challenges with details missing, limbs distortion and the garment style deviation. To address these issues, we propose a Disentangled Representations Diffusion Model (DRDM) to generate photo-realistic images from source portraits in specific desired poses and appearances. First, a pose encoder is responsible for encoding pose features into a high-dimensional space to guide the generation of person images. Second, a body-part subspace decoupling block (BSDB) disentangles features from the different body parts of a source figure and feeds them to the various layers of the noise prediction block, thereby supplying the network with rich disentangled features for generating a realistic target image. Moreover, during inference, we develop a parsing map-based disentangled classifier-free guided sampling method, which amplifies the conditional signals of texture and pose. Extensive experimental results on the Deepfashion dataset demonstrate the effectiveness of our approach in achieving pose transfer and appearance control. The associated project can be found at https://***/lovemusiceb/DRDM. © 2025 IEEE.

As technology permeates people's everyday lives, opportunities arise for HCI to design, develop and research technologies that focus on broader societal challenges such as sustainability, race, gender, and power. Toward this end, we present the Troubling Cups, a provocative design that makes trouble about unequal pay in a work environment. The design was produced through a series of workshops in which women discussed, identified and provotyped trouble in their work environments. Through a small, two-day field study, we explored if and how the provotype made trouble about unequal pay in real-world settings, and how the participants stayed with the trouble of unequal pay. We contribute to our research field with the provotype itself, our qualitative findings, and with our reflections and lessons learned on making trouble and staying with the trouble through provotyping. © 2022 ACM.

Recent research in robotic proxies has demonstrated that one can automatically reproduce many non-verbal cues important in co-located collaboration. However, they often require a symmetrical hardware setup in each location. We present the VRoxy system, designed to enable access to remote spaces through a robotic embodiment, using a VR headset in a much smaller space, such as a personal office. VRoxy maps small movements in VR space to larger movements in the physical space of the robot, allowing the user to navigate large physical spaces easily. Using VRoxy, the VR user can quickly explore and navigate in a low-fidelity rendering of the remote space. Upon the robot’s arrival, the system uses the feed of a 360 camera to support real-time interactions. The system also facilitates various interaction modalities by rendering the micro-mobility around shared spaces, head and facial animations, and pointing gestures on the proxy. We demonstrate how our system can accommodate mapping multiple physical locations onto a unified virtual space. In a formative study, users could complete a design decision task where they navigated and collaborated in a complex 7.5m x 5m layout using a 3m x 2m VR space.
