The technological industry bloomed quite rapidly where the technological solutions have made any process you can think of easier, faster and more efficient. Educational methodologies started off simple, having a teacher using simply his/her words and some writing along with it. With technology entering the field of education, teaching methods were enhanced and the quality of its outcomes was improved. However, sadly in Arab countries that was not the story. In other words, the use of new education technologies is still limited to basic and simple tasks. In fact, to add to the agony, most of the programs used are poorly implemented and rarely applied. Interestingly, as many studies confirm and from the simple observation of kids playing, it is found that most children are very attracted to new technologies and their applications. Those interests not only changed what a normal childhood would look like, but also introduced a multi-billion industry of electronic games. Virtual Reality (VR) games were introduced a few years back starting a gaming revolution, allowing gamers to enter the world of their dreams. Similar to most technologies, VR started to become more affordable with time. Multiple companies have competed to give us amazing VR products such as Samsung Gear. In this manuscript, we present a Virtual Reality Educational Game (VREG), which is an interactive 3D game with Arabic content that targets the students between age 4 and 8 and can be played on a smart phone. VREG includes multiple games that cover the different concepts of Arabic and English languages alongside math, aiming to help the student to learn through playing. In order to make sure that our game reaches wanted education standards, we put it to the test in two private schools;the feedback was very positive from both teachers and students where the majority of users enjoyed their experiments in VR games.展开更多

Speci...Purpose: This study aimed to investigate the immediate effects of optokinetic stimulation (OKS) using virtual reality (VR) on visual dependency and sensory reweighting in postural control during static standing. Specifically, it examined whether VR-based OKS could reduce visual dependency more effectively than visual deprivation through eye closure. Methods: Ten healthy adults participated in this study. A balance function meter was used to measure postural stability, including Romberg ratios before and after two conditions: VR-based OKS (VR + OKS) and eye closure (EC). Participants performed a two-minute standing task under each condition in random order, with adequate rest between tasks. In the VR + OKS condition, a smartphone-based VR headset presented a rotational OKS, while in the EC condition, participants stood with their eyes closed. Statistical analyses were conducted using paired t-tests to compare pre- and post-task Romberg ratios. Results: No significant differences were observed in the pre-task Romberg ratios between conditions. After the VR + OKS condition, significant reductions in Romberg A and Romberg V were observed. In contrast, no significant changes were noted in Romberg ratios after the EC condition. Conclusion: VR-based OKS significantly reduced visual dependency, as indicated by decreased Romberg ratios, suggesting its potential to facilitate sensory reweighting during postural control. These findings highlight the utility of low-cost VR devices in balance rehabilitation for conditions involving high visual dependency. Future studies should expand on this preliminary research by including larger sample sizes and diverse populations to confirm its clinical applicability.展开更多

Man-machine speech cuts off the rational and open dialogue in the public sphere, and interpersonal relationship falls into the social division woven by man-machine relationship. In this process, the authenticity of news has suffered a fierce impact. From the perspective of the development history of media technology, based on the theory of “mimetic environment” put forward by Lippmann, taking ChatGPT as a concrete case, this paper reveals the current situation of the continuous separation between the public and the real and objective environment by analyzing the evolution logic from mimetic environment to multiple virtual worlds, and puts forward some ways to break the ice, such as collaboration between eyewitness evidence and intelligent technology, cooperation between generative AI and journalists, collusion between recommendation algorithm and value orientation, so as to seek an effective path to protect the truth of news and bridge the gap between the virtual and the real world.展开更多

A balance function meter was used to measure postural stability, including Romberg ratios before and after two conditions: VR-based OKS (VR + OKS) and eye closure (EC). Participants performed a two-minute standing task under each condition in random order, with adequate rest between tasks. In the VR + OKS condition, a smartphone-based VR headset presented a rotational OKS, while in the EC condition, participants stood with their eyes closed. Statistical analyses were conducted using paired t-tests to compare pre- and post-task Romberg ratios. Results: No significant differences were observed in the pre-task Romberg ratios between conditions. After the VR + OKS condition, significant reductions in Romberg A and Romberg V were observed. In contrast, no significant changes were noted in Romberg ratios after the EC condition. Conclusion: VR-based OKS significantly reduced visual dependency, as indicated by decreased Romberg ratios, suggesting its potential to facilitate sensory reweighting during postural control. These findings highlight the utility of low-cost VR devices in balance rehabilitation for conditions involving high visual dependency. Future studies should expand on this preliminary research by including larger sample sizes and diverse populations to confirm its clinical applicability.
文摘Background Exploring how immersive technologies can simulate and assess user experiences in designed environments is an important topic in architectural research.In this study,a multisensory virtual reality(VR)system developed to support the study of human-built environment interactions under multimodal conditions(visual,olfactory,and auditory)was evaluated.Methods The effectiveness of the system was tested by conducting in-depth user studies using a mixed-method approach to provide quantitative and qualitative evidence.The results of the case study were discussed,key features of the proposed prototype were assessed,and limitations and opportunities for future studies were identified.Results Findings showed that multisensory elements can deepen participants’sense of presence,increase engagement levels,and enrich overall user experience in immersive environments.Integrating olfactory stimuli into virtual representations of architectural spaces revealed how multisensory feedback informs spatial perception and supports the development of more responsive and human-centered design strategies.Conclusions This study contributes to the emerging field of sensory architecture,aiming to move beyond visual simulation toward a richer embodied understanding of space.The proposed approach provides valuable insights into the development of multisensory VR environments in architecture,enabling future research and immersive research methodologies in wider fields.

文摘In the realm of virtual reality(VR),haptic feedback is integral to enhance the immersive experience;yet,existing wearable devices predominantly rely on skin contact feedback,lacking options for compact and non-contact breeze-sense feedback.Herein,we propose a compact and non-contact working model piezoelectret actuator for providing a gentle and safe breeze sensation.This easy-fabricated and flexible breeze-sense generator with thickness around 1 mm generates air flow pressure up to~163 Pa,which is significantly sensed by human skin.In a typical demonstration,the breeze-sense generators array showcases its versatility by employing multiple coded modes for non-contact information transmitting.The thin thinness and good flexibility facilitate seamless integration with wearable VR setups,and the wearable arrays empower volunteers to precisely perceive the continuous and sudden breeze senses in the virtual environments.This work is expected to inspire developing new haptic feedback devices that play pivotal roles in human-machine interfaces for VR applications.
文摘From the era of mass communication to the era of generative artificial intelligence, under the construction of big data, algorithms and computing power, the mimicry environment has gradually evolved into multiple virtual dreamland: digital replication technology builds the first long-distance online news, and strong editing and weak mining aggravate the alienation of news production and practice;the algorithm model generated randomly by probability creates the second news illusion, and the exhaustibility of calculation makes AIGC completely divorced from reality. Man-machine speech cuts off the rational and open dialogue in the public sphere, and interpersonal relationship falls into the social division woven by man-machine relationship. In this process, the authenticity of news has suffered a fierce impact. From the perspective of the development history of media technology, based on the theory of “mimetic environment” put forward by Lippmann, taking ChatGPT as a concrete case, this paper reveals the current situation of the continuous separation between the public and the real and objective environment by analyzing the evolution logic from mimetic environment to multiple virtual worlds, and puts forward some ways to break the ice, such as collaboration between eyewitness evidence and intelligent technology, cooperation between generative AI and journalists, collusion between recommendation algorithm and value orientation, so as to seek an effective path to protect the truth of news and bridge the gap between the virtual and the real world.

文摘Background This study aimed to explore the influence of prior gaming experience on the intensity and onset of cybersickness symptoms by comparing the effects of virtual reality(VR)immersion in gamers and nongamers.Methods This study involved 50 male participants,with equal numbers of gamers and nongamers,who were subject to a VR environment using head-mounted displays in a sitting position for a 15-minute session.The intensity of cybersickness symptoms,such as nausea,oculomotor disturbances,and disorientation,was measured using a simulator sickness questionnaire,and the onset of cybersickness was measured using the fast motion sickness scale.Physiological indices were measured based on heart rate variability(HRV)parameters.Results This study found that prior gaming experience significantly affected symptoms of cybersickness during VR immersion.Nongamers experienced more severe symptoms,including higher levels of nausea,disorientation,and oculomotor disturbances,with symptoms appearing earlier than those in gamers.These differences were linked to increased fluctuations in HRV and reduced parasympathetic activity in nongamers,indicating higher autonomic nervous system strain.By contrast,gamers showed more stable HRV responses,suggesting better physiological adaptability to VR environments.Conclusion These findings indicate that familiarity of gamers with dynamic visual and sensory inputs may help them manage VR-induced sensory conflicts more effectively.
