Relevant Factors

The use of technological tools is increasing rapidly, especially, in design field. This paper discusses the relevant factors of interaction design associated to the use of new technologies. The research has explored the potential of using virtual reality system to discusses the role substantial that designers must be consider such as: cognitive aspects, human factors, as well as use of new strategic tools to improvement the user experience. Particularly, in the implications for the development of interactive technologies based Immersive virtual reality environment. Through a bibliographic review, provide theoretical elements to development of virtual environments constructed to enhance the communication of information to a better engagement in the experience to its visitors. Therefore, also describes principles for systems based on a user-centered approach, the impact of interaction design in the context of information communication for immersive virtual reality (VR) systems allowing investigating the methods to enhance systems based in the user experience.

The Impact

The progress and development in the fields of technologies in the past few decades are impressive. With so many innovations that have had an impact on human lives and have changed them so drastically, living in a time where new technologies are still making massive changes, and, unquestionably, it wil continue with that trend. As the techniques are continuously evolving, people are forced to prepare ourselves and our descendants to the new and upcoming technologies so that they would be able to understand them, use them, teach others about them and also make some improvements in the specific fields of applications. This article presents an overview of the principal results of research on the impact of Virtual Reality (VR) 3D education for students in industrial vocational training. They were introducedto the generated model and had to explore all elements to have personal experience in the virtual environment. After the training, a user experience survey has been conducted, and the results obtained after the use of the system were presented.

Different Levels

An effective warning attracts attention, elicits knowledge, and enables compliance behavior. Game mechanics, which are directly linked to human desires, stand out as training, evaluation, and improvement tools. Immersive virtual reality (VR) facilitates training without risk to participants, evaluates the impact of an incorrect action/decision, and creates a smart training environment. The present study analyzes the user experience in a gamified virtual environment of risks using the HTC Vive head-mounted display. The game was developed in the Unreal game engine and consisted of a walk-through maze composed of evident dangers and different signaling variables while user action data were recorded. To demonstrate which aspects provide better interaction, experience, perception and memory, three different warning configurations (dynamic, static and smart) and two different levels of danger (low and high) were presented. To properly assess the impact of the experience, we conducted a survey about personality and knowledge before and after using the game. We proceeded with the qualitative approach by using questions in a bipolar laddering assessment that was compared with the recorded data during the game. The findings indicate that when users are engaged in VR, they tend to test the consequences of their actions rather than maintaining safety. The results also reveal that textual signal variables are not accessed when users are faced with the stress factor of time. Progress is needed in implementing new technologies for warnings and advance notifications to improve the evaluation of human behavior in virtual environments of high-risk surroundings.

Position And Orientation

Exoskeletons are an external structural mechanism with joints and links that work in tandem with the user, which increases, reinforces, or restores human performance. Virtual Reality can be used to produce environments, in which the intensity of practice and feedback on performance can be manipulated to provide tailored motor training. Will it be possible to combine both technologies and have them synchronized to reach better performance? This paper consists of the kinematics analysis for the position and orientation synchronization between an n DoF upper-limb exoskeleton pose and a projected object in an immersive virtual reality environment using a VR headset. To achieve this goal, the exoskeletal mechanism is analyzed using Euler angles and the Pieper technique to obtain the equations that lead to its orientation, forward, and inverse kinematic models. This paper extends the author’s previous work by using an early stage upper-limb exoskeleton prototype for the synchronization process.

Before And After

Abstract Tridimensional (3D) rendering of volumetric neuroimaging is increasingly been used to assist surgical management of brain tumors. New technologies allowing immersive virtual reality (VR) visualization of obtained models offer the opportunity to appreciate neuroanatomical details and spatial relationship between the tumor and normal neuroanatomical structures to a level never seen before. We present our preliminary experience with the Surgical Theatre, a commercially available 3D VR system, in 60 consecutive neurosurgical oncology cases. 3D models were developed from volumetric CT scans and MR standard and advanced sequences. The system allows the loading of 6 different layers at the same time, with the possibility to modulate opacity and threshold in real time. Use of the 3D VR was used during preoperative planning allowing a better definition of surgical strategy. A tailored craniotomy and brain dissection can be simulated in advanced and precisely performed in the OR, connecting the system to intraoperative neuronavigation. Smaller blood vessels are generally not included in the 3D rendering, however, real-time intraoperative threshold modulation of the 3D model assisted in their identification improving surgical confidence and safety during the procedure. VR was also used offline, both before and after surgery, in the setting of case discussion within the neurosurgical team and during MDT discussion. Finally, 3D VR was used during informed consent, improving communication with families and young patients. 3D VR allows to tailor surgical strategies to the single patient, contributing to procedural safety and efficacy and to the global improvement of neurosurgical oncology care.
