Special Issue Information

Dear Colleagues,

The fields of human–computer interaction (HCI) and extended reality (XR) are closely connected, given that they both focus on technologies that enhance interactions between humans, computers, and virtual environments, thereby fostering numerous societally beneficial applications. HCI is dedicated to refining interfaces by innovating in terms of both software and hardware designs and incorporating cutting-edge technologies such as machine learning, gesture recognition, and biosignal processing. Advancements in HCI drive not only technological progress but also facilitate seamless interactions in both real and virtual settings, enhancing the extended reality experience overall. XR, encompassing virtual reality (VR), augmented reality (AR), and mixed reality (MR), blurs the boundaries between the real and virtual worlds, creating a spectrum of applications in numerous fields.

This Special Issue invites contributions that explore pioneering research at the intersection of HCI and virtual environments, and which shape the evolving landscape of these dynamic fields.

Topics include, but are not limited to:

  • HCI and XR Innovations: novel approaches in software and hardware design, gesture recognition, behavioral analytics, virtual assistants, and wearable interfaces;
  • Virtual Environments: research on XR technologies, spanning diverse fields such as education, healthcare, entertainment, and architecture;
  • User Experience (UX): a focus on enhancing UX in virtual environments through studies on interaction, interface design, and the field’s psychological aspects;
  • Technological Advancements: highlighting progress in supporting technologies, including machine learning, biometric sensing, haptics, and sensory feedback;
  • Applications and Impact: exploration of real-world applications and impact assessments of HCI and XR;
  • Ethical Considerations: discussions on ethical implications, addressing issues such as accessibility, responsible development, and the use of immersive technologies.

This work aims to define a strategy for maintaining a vertical posture of the human body under conditions of conflicting sensory stimuli using a method of trend change analysis. The investigations involved 28 healthy individuals (13 females, 15 males, average age = 21, SD = 1.3 years). Measurements were conducted with eyes opened and closed and in the virtual environment with two sceneries oscillating at two frequencies. Values in the time domain were calculated—the mean center of pressure (COP) velocity and movement range in the AP direction—as well as values based on the moving average convergence divergence (MACD) computational algorithm—the trend change index (TCI), MACD_dT, MACD_dS, and MACD_dV. After dividing the analysis into distinct time periods, an increase in TCI values was identified in the oscillating scenery at 0.7 and 1.4 Hz during the 0.5–1 and 0.2–0.5 s time periods, respectively. Statistically significant differences were observed between measurements with an oscillation frequency of 0.7 Hz and those with an oscillation frequency of 1.4 Hz during the 0.2–0.5 s and 0.5–1 s periods. The use of stock exchange indices in the assessment of the ability to keep a stable body posture supplements and extends standard analyses in the time and frequency domains. Full article

In complex environments, users frequently need to manage multiple tasks simultaneously, which poses significant challenges for user interface design. For instance, when driving, users must maintain continuous visual attention on the road ahead while also monitoring rearview mirrors and performing shoulder checks. These multitasking scenarios present substantial design challenges in effectively guiding users. To address these challenges, we focus on investigating and designing visual and haptic guidance systems to augment users’ performance. We initially propose the use of visual guidance, specifically employing a dynamic arrow as a guidance technique. Our evaluation shows that dynamic arrows significantly expedite both reaction and selection times. We further introduce and evaluate haptic feedback, which users perceive as more salient than visual guidance, leading to quicker responses when switching from primary to secondary tasks. This allows users to maintain visual attention on the primary task while simultaneously responding effectively to haptic cues. Our findings suggest that multimodal guidance, especially haptic guidance, can enhance both reaction time and user experience in dual-task environments, offering promising practical implications and guidelines for designing more user-friendly interfaces and systems.

In recent years, the number of applications of virtual reality (VR) for the Autism spectrum disorder (ASD) population has increased and has become one of the most suitable tools to address the psychological needs of these individuals. The present scoping review aims to provide a literature mapping of experimental studies that have used immersive and semi-immersive VR for assessments or interventions specifically addressing high-functioning autism. A total of 23 papers were included and analyzed following PRISMA guidelines. The identified studies concerned social skills (11 papers), eye gaze and joint attention (3 papers), motor learning (3 papers), job training (2 papers), and other aims or rationales (4 papers). The evidence shows that, despite the intellectual potential of high-functioning ASD individuals, little research has been conducted to provide interventions that offer concrete training to improve their adaptive functioning. In addition, the percentage of individuals below 18 years of age is representative of half of the included studies, so aiming future studies at the early stages of development might be an asset in preparing the next generation of young adults to cope with age-related challenges, as early assessments and interventions are more likely to produce major long-term effects.
