The procedure is taught and trained as part of the interventionist cardiology curriculum. The cognitive and motor skills required to complete this procedure are key during the patient's treatment, and are only achieved through extensive training. Currently, there is great concern among physicians regarding the dependency on high-end equipment requiring large investments that can limit the number of practices students can get. This paper presents the development of two virtual reality (VR) simulation prototypes for PCI training for treating Acute Myocardial Infarction. Our approach employs a virtual reality headset and a smartphone to compare their effects on the training experience. The visual immersion and non immersion effects are compared by gathering usability perceptions finding that the simulator has potential as a learning tool for medical education using VR technology.

The ability to interpret heart sounds is key during the diagnosis and only achieved through extensive training. Currently, there is great concern among physicians regarding the loss of cardiac auscultation skills, and the effects on proper diagnoses that may lead to inadequate treatments. Current cardiac auscultation training employs equipment that completes the diagnose without the use of a stethoscope, diminishing the amount of practice trainees obtain with it. However, despite the decreased emphasis on stethoscope training, the stethoscope remains a cost-effective tool and relevant in several examination scenarios. This paper presents the development of a mobile virtual reality prototype for cardiac auscultation training. Our approach employs a virtual reality headset to facilitate training. We analyzed the effect of visual immersion on auscultation training, by comparing its usability perception to a non-VR auscultation training app.

Starting from the characterization of the procedure, all the steps were mapped to a virtual environment. The prototype implemented include two main actors, the surgeon and the medical instrumentalist, and observers that can join the simulation at any time. Voice chat was included in order to allow lifelike operating room communication, a key element for a successful simulation. Initial evaluation indicated that the proposed solution is promising in a work-from-home environment as a complementary tool for medical education.

In the field of vascular access, the use of virtual reality has been emerging as a complement to address the current problems due to the low availability of simulation manikins for training and its high cost. Intraosseous access in newborns is an invasive, fast and effective medical procedure of high complexity employed in critically ill newborns as an option to access veins after peripheral access has failed. Due to vein vasoconstriction present in neonatal shock and cardiorespiratory arrest among other life-threatening conditions it is difficult to perform any other forms of venous access. Intraosseous access requires the proper handling of the related equipment and knowledge, this is only possible with continuous training that cannot be done in real patients. Mastering this technique is required to preserve patient's life, achieve a good recovery and reduce the risk of infection or even death. This paper presents the development of a newborn's intraosseous access simulator for training covering the required steps involved in the procedure. To increase the immersion of the simulation, a force feedback haptic device is integrated to simulate the needle insertion beneath leg tissues to the bone with a biomechanical tissue model, which is the more important skill to be developed in this procedure, and a consumer head mounted display to provide a stereo view of the operation room to give depth to the user when approaching to the patient leg. Our preliminary results were evaluated by a medical expert in terms of usability of the prototype.

Current cardiac auscultation training is seeing a preference towards diagnostics equipment such as the echocardiograph that allows visualizing and listening to the heart to determine how the heart is working, rather than the use of the stethoscope which only provides auditory feedback, resulting in a loss of stethoscope-based cardiac auscultation skills which are relevant in situations where it is the only cost-effective option available. Currently, virtual reality, simulation, and games are taking a prominent role in medical training, providing consumer-level immersive and interactive realistic experiences. Within these fields, user interfaces can provide more appropriate forms of interactions for developing cognitive and psychomotor skills. However, traditional controllers are widely employed and do not map adequately the functionality of real medical equipment, including the stethoscope. In this paper, w...

Current auscultation training is seeing a trend in favour of employing diagnostics equipment, which in comparison to a stethoscope-based examination, provides a comprehensive visualization of the heart. However, despite employing advance auscultation equipment, heart diagnosis skills with the stethoscope are declining. The loss of such skills has caused concern amongst physicians, as the stethoscope remains widely available and affordable worldwide, unlike other specialized tools. Currently, simulation is being employed to improve the diagnosis of heart conditions since mastering cardiac auscultation skills requires extensive training due to the complexity of the heart murmurs. Moreover, high fidelity medical simulators provide realism and accuracy at a high cost, thus providing suitable training but limited practices depending on the number o...

The use of natural motion has been growing among user interface researches and developers for offering comfortable ways of interacting with the devices around us. Some examples can be seen in how touch screens, accelerometers and image processing have influenced our interactions with cellphones, gaming devices and computers, thus, allowing us to take advantage of our body ergonomics. The objective of this work is to integrate an intuitive tool for teleoperating a mobile robot through gestures as an alternative input for encouraging non-experts to relate with robotics and ease navigation tasks. For accomplishing the objective of this work, the mobile robots programming architecture is studied and integrated with those of the user interfaces for allowing the teleoperation of the robotics device. To check how the implemented framework impacts the user interaction, a navigation scenario with obstacles is used for validating the suitability of the gesture-based navigation.

Additionally, simulators provide controllable patient conditions that can be configured to improve decision-making in time-sensitive medical procedures. The study of myocardial infarction treatment cardiology relies on analyzing medical cases and patient examination under medical supervision. However, the lack of practice can result in a human error that can be minimized with the simulation. In this paper, a virtual reality simulator prototype that allows students to practice the myocardial infarction procedure based on the American Heart Association guidelines is presented. The proposed prototype uses immersive virtual reality technology to create an engaging situation where the students will be able to recreate the treatment on a virtual patient. The prototype presents an immersive and interactive approach that can benefit the adherence to current myocardial infarction guidelines.

Las ayudas visuales tradicionales están basadas en fotografías, ilustraciones, bosquejos y observación directa de los tejidos a través de microscopio, y todas ellas, aun cuando complementarias, presentan algunas limitantes debido a la naturaleza microscópica de algunas partes del oído. Para solucionar las deficiencias presentadas en las técnicas actuales, se propone el desarrollo de una herramienta computacional complementaria que incluya modelos 3D animados e información sobre cada órgano siguiendo los requerimientos de especialistas en el área. Los modelos 3D fueron desarrollados a partir t...

Even though sensor based technologies and tracking systems have been around for several years, recently they have become affordable and used in several areas such as physical and mental rehabilitation, educational applications, physical exercises, and natural interactions, among others. This work presents the integration of two mainstream videogame interfaces as tools for developing an interactive lower and upper member therapy tool. The goal is to study the potential of these devices as complementing didactic elements for improving and following user performance during a series of exercises with virtual and real devices.
