This one-day workshop seeks to advance the discussion around making and fabrication in HCI research, including notions of hobbyist making and industrial production. These different fabrication cultures are the starting point for the workshop, which attempts to contour the landscape of fabrication and how it influences and is influenced by HCI (research). The proposed workshop extends from two prior efforts in this space: a workshop held at the 5th Decennial Aarhus Conference and a three-day summit in Austria in September 2015 on "Rethinking Technology Innovation: Factories, Fabrication & Design Research". © 2016 Authors.

Visual Simultaneous Localization and Mapping (vSLAM) is a cornerstone technology in computer vision and robotics, underpinning applications such as autonomous vehicles and robot navigation. While traditional vSLAM systems have shown significant progress in indoor or outdoor environments, their performance often degrades in complex scenes, limiting their adaptability and robustness. Semantic vSLAM, which integrates high-level semantic information into vSLAM systems, has emerged as a promising solution to address these limitations by enabling a richer understanding of the environment. In this paper, we provide a comprehensive review of semantic vSLAM, offering a critical analysis of its evolution, methods, and challenges. We begin by revisiting the development of traditional vSLAM, emphasizing its limitations and the motivation for incorporating semantic information. Subsequently, we delve into the core modules of semantic vSLAM, including semantic extraction, object association, semantic loop closing, back-end optimization, and semantic mapping. Then, we present a performance comparison of semantic vSLAM systems under two different datasets, indoor and outdoor, respectively. Furthermore, we also provide a comparative analysis of widely used SLAM datasets to provide guidance for performance testing and validation. To further enrich the discussion, we identify unresolved challenges in semantic vSLAM, such as long-term semantic perception and association, open and unstructured environments. We propose future research directions, including balancing computational resources and quantifying system risk, large model-based navigation and mapping, and embodied AI SLAM. By providing key insights and forward-looking perspectives, this work aims to stimulate future research and improve the capabilities of semantic vSLAM in real-world applications. © 2000-2011 IEEE.

This paper presents results from a preliminary analysis of interaction and human observation data gathered from students using an Aplusix, an intelligent tutoring system for algebra. Towards the development of automatic detectors of behavior and affect, this study tried to determine whether it was possible to identify distinct groups of students based on interaction logs alone. Using unsupervised clustering, we were able to identify that student behaviors within the software cluster into two categories, Clusters 0 and 1, associated with differing higher-level behaviors and affective states. Cluster 0 tended to reflect more collaborative work, whereas Cluster 1 reflected more solitary work. Cluster 1 students tended to exhibit more flow, suggesting that students in flow tend to work in a more individual fashion. An examination of the keystrokes used by each group showed that Cluster 0 used the arrow keys and cursor keys significantly more than Cluster 1. The Cluster 1, on the other hand, tended to type more mathematical operators or use the duplicate command more frequently than Cluster 0. This implies that frequent use of mathematical operators and frequent duplication of the problem may be evidence of flow within Aplusix.

This paper aims at designing and constructing an ontology, representing and allowing Vietnamese folk dances annotation. An effective approach proposed is based on movement analysis. It is possible to divide Vietnamese folk dances into basic units, then movement phrases, movement primitives and dance poses. Studying deeply Vietnamese folk dances features and characteristics allows to find out 5 different types of relationships between main dance components. Typical relationships could be written in the form of logical predicates. For enriching ontologies, a formal encoding of the ontology expertise knowledge in the domain is performed by DL-Lite. The paper uses OWL-2 for building, organizing and visualizing ontologies. A case study-Mo folk dance with a knowledge base, is structured simply but effectively, with reasoning in DL-Lite and answering queries in SPARQL. © 2018 IEEE.

In this paper, we proposed an in-vehicle haptic navigation system to overcome some limitations of current in-vehicle navigation aid systems. The haptic interface using vibrotactile signals with a 5-by-5 tactor array was installed on the back of the chair. To evaluate the effectiveness of the proposed system in various cognitive load conditions, we implemented a visual search experiment using a flicker paradigm. Sixteen participants were recruited to evaluate the proposed haptic navigation system. The two independent variables were validity (valid cue, invalid cue, and no cueing) and cognitive load levels (high and low) of search tasks. Despite of the cognitive load levels, the valid cue conditions elicited shorter response times than invalid cue and no cueing conditions. The result strongly supports the effectiveness of the proposed in-vehicle navigation systems. © 2012 Springer science+Business Media.

We describe progress using a user-centered design process to migrate a family therapy game to a web-based therapist tool, called FamilySense, that supports therapists creating part of the therapeutic game. Using cards with questions about players' daily life and alternative answers considering their cultural context, the game gives parent and child awareness of each other. Online design of different elements for the board, cards and communication provide an effective online therapy tool. Four user-centered design process stages are presented including: design strategies, design questions, stakeholders, prototype and evaluation for each stage. The process has been successful for the migration, achieving an online game environment that shows strong potential for a family therapy tool. © 2010 Copyright is held by the author/owner(s).

Population aging resulting from demographic changes requires some challenging decisions and necessary steps to be taken by different stakeholders to manage current and future demand for assistance and support. The consequences of population aging can be mitigated to some extent by assisting technologies that can support the autonomous living of older individuals and persons in need of care in their private environments as long as possible. A variety of technical solutions are already available on the market, but privacy protection is a serious, often neglected, issue when using such (assisting) technology. Thus, privacy needs to be thoroughly taken under consideration in this context. In a three-year project PAAL (‘Privacy-Aware and Acceptable Lifelogging Services for Older and Frail People’), researchers from different disciplines, such as law, rehabilitation, human-computer interaction, and computer science, investigated the phenomenon of privacy when using assistive lifelogging technologies. In concrete terms, the concept of Privacy by Design was realized using two exemplary lifelogging applications in private and professional environments. A user-centered empirical approach was applied to the lifelogging technologies, investigating the perceptions and attitudes of (older) users with different health-related and biographical profiles. The knowledge gained through the interdisciplinary collaboration can improve the implementation and optimization of assistive applications. In this paper, partners of the PAAL project present insights gained from their cross-national, interdisciplinary work regarding privacy-aware and acceptable lifelogging technologies. © 2022, The Author(s).

This study investigates the effectiveness of the application of Virtual Reality Training (VRT) in the treatment of Communication Apprehension (CA). The participants were thirty undergraduate volunteer students enrolled at the university level. Virtual reality software and hardware were used to create a virtual auditorium scene for this training. Over five sessions, participants were subjected to virtual public speaking scenarios of varying intensity. Subjective Units of Disturbance (SUD) scale was used to measure the participants' anxiety levels. The average level of anxiety reported during post-test was significantly less than that of the pre-test. The preliminary results indicated that VRT could be used as an effective method for reducing CA in clients and allow them to become involved in discussions and presentations more comfortably.

Many failures in long-term collaboration occur because of a lack of activity awareness. Activity awareness is a broad concept that involves awareness of synchronous and asynchronous interactions over extended time periods. We describe a procedure to evaluate activity awareness and collaborative activities in a controlled setting. The activities used are modeled on real-world collaborations documented earlier in a field study. We developed an experimental method to study these activity awareness problems in the laboratory. Participants worked on a simulated long-term project in the laboratory over multiple experimental sessions with a confederate, who partially scripted activities and probes. We present evidence showing that this method represents a valid model of real collaboration, based on participants' active engagement, lively negotiation, and awareness difficulties. We found that having the ability to define, reproduce, and systematically manipulate collaborative situations allowed us to assess the effect of realistic conditions on activity awareness in remote collaboration.

Recognizing a piece of writing as a poem or prose is usually easy for the majority of people;however, only specialists can determine which meter a poem belongs to. In this paper, we build Recurrent Neural Network (RNN) models that can classify poems according to their meters from plain text. The input text is encoded at the character level and directly fed to the models without feature handcrafting. This is a step forward for machine understanding and synthesis of languages in general, and Arabic language in particular. Among the 16 poem meters of Arabic and the 4 meters of English the networks were able to correctly classify poem with an overall accuracy of 96.38% and 82.31% respectively. The poem datasets used to conduct this research were massive, over 1.5 million of verses, and were crawled from different nontechnical sources, almost Arabic and English literature sites, and in different heterogeneous and unstructured formats. These datasets are now made publicly available in clean, structured, and documented format for other future research. To the best of the authors' knowledge, this research is the first to address classifying poem meters in a machine learnin g approach, in general, and in RNN featureless based approach, in particular. In addition, the dataset is the first publicly available dataset ready for the purpose of future computational research. Copyright © 2019, The Authors. All rights reserved.
