Objective: Fibromyalgia (FM) is a syndrome marked by chronic pain, fatigue, and mood disorders. Nonpharmacologic strategies are recommended to avoid overuse of opioids or nonsteroidal anti-inflammatory drugs, but current approaches often provide limited relief. This study aimed to preliminarily assess the efficacy and feasibility of a new combined intervention of immersive virtual reality with multisensor biofeedback (IVR-BF) in FM management. Methods: In this single-center, pilot, open-label, randomized controlled trial, adult patients with FM were randomly assigned 1:1 to either the treatment (TR) group, receiving IVR-BF immediately, or a waitlist control (WL) group, receiving IVR-BF after the TR group completed treatment. The primary outcome was reduction in visual analog scale (VAS) pain scores in the TR group, after five IVR-BF sessions, compared to the WL group, after the waiting period. Secondary outcomes included improvements in FM impact (FM Impact Questionnaire [FIQ] score) and qualitative aspect of pain (Short-form McGill Pain Questionnaire [SF-MPQ] score). A longitudinal analysis was conducted across all patients to examine the trends in VAS pain, SF-MPQ, and FIQ score during the trial. Results: Fifty patients were screened, and 20 female patients (10 TR and 10 WL) completed the trial and were analyzed. Those in the TR group showed significantly lower VAS pain scores compared to those in the WL group (P = 0.011), along with significant improvement in the FIQ score (P = 0.018). The longitudinal analysis revealed progressive improvements in VAS pain, SF-MPQ, and FIQ score, supported by physiologic improvements (heart rate variability, respiratory rate, skin conductance). No significant safety concerns were reported. Patients expressed a high level of satisfaction with the IVR experience. Conclusion: IVR-BF is a feasible treatment that shows potential in reducing pain and improving quality of life in patients with FM, supporting the need for larger trials t

Recent research has shown that developers spend significant amounts of time navigating around code. Much of this time is spent on redundant navigations to code that the developer previously found. This is necessary today because existing development environments do not enable users to easily collect relevant information, such as web pages, textual notes, and code fragments. JASPER is a new system that allows users to collect relevant artifacts into a working set for easy reference. These artifacts are visible in a single view that represents the user's current task and allows users to easily make each artifact visible within its context. We predict that JASPER will significantly reduce time spent on redundant navigations. In addition, JASPER will facilitate multitasking, interruption management, and sharing task information with other developers. © 2006 ACM.

Robot grasping is of paramount importance in industrial and service robotics. In recent years, various data-driven algorithms have been proposed to solve the problem of grasp detection and a part of them are based on reinforcement learning (RL) approaches. In a variety of proposed algorithms, random key points are being employed which will make the learning process inefficient and time-consuming. In this paper, a geometry-based algorithm is presented which can find grasp poses based on the geometry of the unknown object and propose the ones which may lead to successful grasping. For the grasp contacts computation part, the presented algorithm produces a finite number of key points based on the 2D shape of the object from a specific point of view. Afterward, it will narrow down the candidate points and output a finite number of successful grasp poses based on three grasp quality metrics for various unknown objects. Three approaches are proposed in order to achieve center points which can describe different parts of a 2D shape. Then, the obtained points are used as the center of circles which are tangent to the 2D shape contour. Also, a new grasp quality metric is proposed. The time of the grasp and the amount of object disorientation after grasping are considered as a metric to evaluate the successfulness of the grasp. Simulation results demonstrate that the proposed algorithm for unknown object grasping can find a finite number of successful grasp poses for different seen or unseen objects without using any random point © 2023 IEEE.

We present OZONE (Zoomable Ontology Navigator), for searching and browsing ontological information. OZONE visualizes query conditions and provides interactive, guided browsing for DAML (DARPA Agent Markup Language) ontologies on the Web. To visually represent objects in DAML, we define a visual model for its classes, properties and relationships between them. Properties can be expanded into classes for query refinement. The visual query can be formulated incrementally as users explore class and property structures interactively. Zoomable interface techniques are employed for effective navigation and usability. © 2009 ACM.

Hypertext, perhaps more than any other interface philosophy to date, lends itself to very diverse applications. Hypertext is particularly appropriate for systems intended for public access and widely-accessible computing. One of the challenges facing designers of hypertext-based kiosk systems is to identify effective, non-keyboard based searching strategies. In the CHI'89 InfoBooth, the original searching mechanism encouraged a mixture of hierarchical and linear searching, but it was found, in practice, to be quite awkward. In our study, subjects used modified versions of the Infobooth to answer questions in one of three search modes: hierarchical, linear or mixed. In terms of speed and minimizing the number of cards visited, the hierarchical approach was far superior. We believe that the hierarchical mode was superior because the tool mimicked the structure of the information. We conclude that as a general rule, designers should provide a tool which matches the search pattern. In the case of multiple patterns, we recommend providing multiple, non-ambiguous tools. © Springer-Verlag Berlin Heidelberg 1994.

Using recipes in a step-by-step format with multimedia enhancements has been found to increase confidence and enjoyment of cooking but the field lacks research with cooks on the problems they encounter, so it is unclear what granularity of recipe step and associated multimedia would best support them. The current study observed 16 cooks prepare 3 dishes using recipes in 3 different formats to understand what problems cooks have with recipes. Recipe format had a significant effect on the ratings given to the recipe for clarity and ease of use but not on time to complete the recipe. Analysis of cooking activity and cooks' feedback shows that cooks want (i) step-by-step recipes with ingredient quantities in the recipe step, (ii) pictures of the interim states of the recipe, (iii) videos of preparation of unfamiliar ingredients, and (iv) videos of preparation techniques with different types of utensils. © 2011 IEEE.

Big Data analytics and Artificial Intelligence systems derive non-intuitive and often unverifiable inferences about individuals’ behaviors, preferences, and private lives. Drawing on diverse, feature-rich datasets of unpredictable value, these systems erode the intuitive connection between our actions and how we are perceived, diminishing control over our digital identities. While Explainable Artificial Intelligence scholars have attempted to explain the inner workings of algorithms, their visualizations frequently overwhelm end-users with complexity. This research introduces ‘hypothetical inference’—a novel approach that uses language models to simulate how algorithms might interpret users’ digital footprints and infer personal characteristics without requiring access to proprietary platform algorithms. Through empirical studies with fourteen adult participants, we identified three key design opportunities to foster critical algorithmic literacy: (1) reassembling scattered digital footprints into a unified map, (2) simulating algorithmic inference through LLM-generated interpretations, and (3) incorporating temporal dimensions to visualize evolving patterns. This research lays the groundwork for tools that can help users recognize the influence of data on platforms and develop greater autonomy in increasingly algorithm-mediated digital environments.

Empirical evidence of the benefits of immersion is an important goal for the virtual environment (VE) community. Direct comparison of immersive systems and non-immersive systems is insufficient because differences between such systems may be due not only to the level of immersion, but also to other factors, such as the input devices and interaction techniques used. In this paper, a study is presented that separates the effects of level of immersion and 3D interaction technique for a six-degree-of-freedom manipulation task. In the study, two components of immersion - stereoscopy and field of regard - were varied and three 3D interaction techniques - HOMER, Go-Go, and DO-IT (a new keyboard- and mouse-based technique) - were tested. The results of the experiment show that the interaction technique had a significant effect on object manipulation time, while the two components of immersion did not. The implications of these results are discussed for VE application developers. Copyright 2006 ACM.
