Augmented Reality

The study seeks to assess the efficacy of incorporating augmented reality (AR) or virtual reality (VR) technology into ultrasound-guided medical procedures such as regional anesthesia and line placement. By utilizing AR/VR devices, the investigators will improve the ergonomics when using ultrasound to guide procedures. The aims are to enhance visualization of anatomical structures and improve procedural accuracy for clinicians. The study aims to evaluate the feasibility, and effectiveness of integrating AR/VR technology into ultrasound-guided procedures, with the ultimate goal of improving patient outcomes.

However, no study has been found in the care of preeclampsia, which is highly effective on maternal and fetal health. Therefore, this study was planned to determine the effect of augmented reality-based training on the diagnosis and intervention planning skills of nursing students.

The goal of this clinical trial is to assess the Usability, adherence, acceptance, and security of an augmented reality platform for balance training in patients with balance disorders due to degenerative injuries or cerebrovascular diseases. The main questions it aims to answer are: * Is the augmented reality system usable, acceptable, and safe with good adherence? * Does the system improve the balance in our population? * Participants will be asked to assist at Vall d'Hebrón Hospital, where patients will undergo balance training under the supervision of a physiotherapist three days a week for four weeks. * If the patients meet the inclusion criteria, the intervention will be extended for two more weeks at home.

Cadaver use in anatomy education is undergoing several limitations in many universities, due to high costs, time constraints and supply difficulties. As alternatives to cadaver dissections, new teaching methods based on visual technologies, such as augmented reality (AR), are being implemented worldwide. Augmented reality (AR), based on virtual interactive 3-dimensional elements (holograms) overlaid in the real-world, represents a promising alternative to explore the human body. In this study, we will test the efficacy of AR as an alternative teaching method in anatomy education by comparing traditional learning methods based on 2-dimensional (2D) images, videos, and online learning programs with the novel AR learning module The primary endpoint will consist of the score in the final theoretical and practical knowledge tests, assessed at two timepoints: immediately after the study session and after 3 months. Secondary endpoints will include adverse health symptoms and user experience, assessed immediately after the study session.
