“…However, VR offers a three-dimensional perception that enhances the feeling of presence and realism compared to 2D screen viewing. Much research has documented the comparisons that support the advantages inherent in the use of this technology [46][47][48][49].…”

This study researches the combination of the brain–computer interface (BCI) and virtual reality (VR) in order to improve user experience and facilitate control learning in a safe environment. In addition, it assesses the applicability of the phase-locking value spatial filtering (PLV-SF) method and the Short-Term Memory Network (LSTM) in a real-time EEG-based BCI. The PLV-SF has been shown to improve signal quality, and the LSTM exhibits more stable and accurate behavior. Ten healthy volunteers, six men and four women aged 22 to 37 years, participated in tasks inside a virtual house, using their EEG states to direct their movements and actions through a commercial, low-cost wireless EEG device together with a virtual reality system. A BCI and VR can be used effectively to enable the intuitive control of virtual environments by immersing users in real-life situations, making the experience engaging, fun, and safe. Control test times decreased significantly from 3.65 min and 7.79 min in the first and second quartiles, respectively, to 2.56 min and 4.28 min. In addition, a free route was performed for the three best volunteers who finished in an average time of 6.30 min.

“…The Evo-Streets [42] approach also uses the city metaphor, but uses streets to represent the package decomposition instead of nested boxed areas in CodeCity. Multiple approaches also reuse the city metaphor by adding other visual dimensions such as arcs between buildings [82,83] or by adapting it to more immersive techniques, such as virtual reality for CodeCity [84] and VRCity [85], or Minecraft for CodeMetropolis [86].…”

“…3D metaphors borrow analogies from the physical world to exploit viewers' familiarity with real-world constructs, e.g., cities, islands, or planets [1,8,10,13,17,26,28]. 3D software visualizations can be distinguished by the medium they employ, i.e., computer screens, augmented reality, or virtual reality [16,18].…”

Software visualization facilitates the interactive exploration of largescale code bases, e.g., to rediscover the architecture of a legacy system. Visualizations of software structure suffer from repetitive patterns that complicate distinguishing different subsystems and recognizing previously visited parts of an architecture.We leverage variability-modeling techniques to "uniquify" visualizations of subsystems via custom-tailored 3D models of recognizable landmarks: For each subsystem, we derive a descriptor and translate it to a (random but deterministic) configuration of a feature model of variable 3D geometry to support large numbers of different 3D models while capturing the design language of a particular type of landmark. We devised a hybrid variant derivation mechanism using a slots-and-hooks composition system for 3D geometry as well as adjusting visual characteristics, e.g., material. We demonstrate our method by creating various different trophies as landmarks for the visualization of a software system.
