Virtual environments (VEs) that represent real spaces (RSs) give people who are blind the opportunity to build a cognitive map in advance that they will be able to use when arriving at the RS. The paper aims to discuss this issue.

In this research study Nintendo Wii-based technology was used for exploring VEs via the Wiici application. The Wiimote allows the user to interact with VEs by simulating walking and scanning the space.

By getting haptic and auditory feedback the user learned to explore new spaces. The authors examined the participants’ abilities to explore new simple and complex places, construct a cognitive map, and perform orientation tasks in the RS.

To the authors’ knowledge, this finding presents the first VE for people who are blind that allow the participants to scan the environment and by this to construct map model spatial representations.

The purpose of this paper is to examine the past 15 years of research and development (R&D) on the role of virtual environments (VEs) as an orientation and mobility (O&M) aid to enhance skills and to train people who are blind or newly blind.

This paper describes and examines studies of 21 VE systems developed specifically to help people who are blind improve their O&M skills. These VE systems, equipped to supply appropriate perceptual and conceptual spatial information through haptic and auditory sensorial channels, are mainly focussed on two goals: helping congenitally blind or late blind persons to collect spatial information in advance and supporting people who are newly blind in practicing their O&M skills during rehabilitation. The R&D studies represented in these 21 studies were examined along three dimensions: descriptive information, system, and research.

This paper highlights weaknesses and strengths of VE systems that have been developed in the past 15 years as O&M aids for people who are blind. These results have the potential to influence future R&D in this field.

The author hopes that this paper will influence future R&D in this field and lead to accessible O&M VEs in practice and research.

This research is based on the hypothesis that the supply of appropriate perceptual and conceptual information through compensatory sensorial channels may assist people who are blind with anticipatory exploration. The two main goals of the research are: evaluation of different modalities (haptic and audio) and navigation tools; and evaluation of spatial cognitive mapping employed by people who are blind.

In this research the BlindAid system, which allows the user to explore a virtual environment, was developed and tested. The research included four participants who are totally blind.

The preliminary findings confirm that the system enabled participants to develop comprehensive cognitive maps by exploring the virtual environment. The BlindAid system could be used as a training‐simulator for O&M rehabilitation training, as a O&M diagnostic tool, and to support people who are blind in exploring and collecting spatial information in advance.

This preliminary study aims to highlight which VE properties could provide perceptual and conceptual spatial information and allow users who are blind to gather and expand their spatial information.

The purpose of this paper is to examine a central need of students who are blind: the ability to access science curriculum content.

Agent-based modeling is a relatively new computational modeling paradigm that models complex dynamic systems. NetLogo is a widely used agent-based modeling language that enables exploration and construction of models of complex systems by programming and running the rules and behaviors. Sonification of variables and events in an agent-based NetLogo computer model of gas in a container is used to convey phenomena information. This study examined mainly two research topics: the scientific conceptual knowledge and systems reasoning that were learned as a result of interaction with the listen-to-complexity (L2C) environment as appeared in answers to the pre- and post-tests and the learning topics of kinetic molecular theory of gas in chemistry that was learned as a result of interaction with the L2C environment. The case study research focused on A., a woman who is adventitiously blind, for eight sessions.

The participant successfully completed all curricular assignments; her scientific conceptual knowledge and systems reasoning became more specific and aligned with scientific knowledge.

A practical implication of further studies is that they are likely to have an impact on the accessibility of learning materials, especially in science education for students who are blind, as equal access to low-cost learning environments that are equivalent to those used by sighted users would support their inclusion in the K-12 academic curriculum.

The innovative and low-cost learning system that is used in this research is based on transmittal of visual information of dynamic and complex systems, providing perceptual compensation by harnessing auditory feedback. For the first time the L2C system is based on sound that represents a dynamic rather than a static array. In this study, the authors explore how a combination of several auditory representations may affect cognitive learning ability.

Accessible games, both for serious and for entertainment purposes, would allow inclusion and participation for those with disabilities. Research into the development of accessible games, and accessible virtual environments, is discussed. Research into accessible Virtual Environments has demonstrated great potential for allowing people who are blind to explore new spaces, reduce their reliance on guides and aid development of more efficient spatial maps and strategies. Importantly, Lahav and Mioduser (2005, 2008) have demonstrated that, when exploring virtual spaces, people who are blind use more and different strategies than when exploring real physical spaces, and develop relatively accurate spatial representations of them. The present paper describes the design, development and evaluation of a system in which a virtual environment may be explored by people who are blind using Nintendo Wii devices, with auditory and haptic feedback. The nature of the various types of feedback is considered, with the aim of creating an intuitive and usable system. Using Wii technology has many advantages: it is mainstream, readily available and cheap. The potential of the system for exploration and navigation is demonstrated. Results strongly support the possibilities of the system for facilitating and supporting the construction of cognitive maps and spatial strategies. Intelligent support is discussed. Systems such as the present one will facilitate the development of accessible games, and thus enable Universal Design and accessible interactive technology to become more accepted and widespread.

VirtuNav is a haptic-, audio-enabled virtual reality simulator that facilitates persons with visual impairment to explore a 3D computer model of a real-life indoor location, such as a room or building. The purpose of this paper is to aid in pre-planning and spatial awareness, for a user to become more familiar with the environment prior to experiencing it in reality.

The system offers two unique interfaces: a free-roam interface where the user can navigate, and an edit mode where the administrator can manage test users, maps and retrieve test data.

System testing reveals that spatial awareness and memory mapping improve with user iterations within VirtuNav.

VirtuNav is a research tool for investigation of user familiarity developed after repeated exposure to the simulator, to determine the extent to which haptic and/or sound cues improve a visually impaired user’s ability to navigate a room or building with or without occlusion.

The application may prove useful for greater real world engagement: to build confidence in real world experiences, enabling persons with sight impairment to more comfortably and readily explore and interact with environments formerly unfamiliar or unattainable to them.

VirtuNav is developed as a practical application offering several unique features including map design, semi-automatic 3D map reconstruction and object classification from 2D map data. Visual and haptic rendering of real-time 3D map navigation are provided as well as automated administrative functions for shortest path determination, actual path comparison, and performance indicator assessment: exploration time taken and collision data.

This study aims to investigate the US cruise market by analyzing industry trends and consumer psychology. COVID-19 has coexisted with human beings for more than two years, and scientists claim that human beings will continuously live with the virus for a long time. Nowadays, cruise tourism and the COVID-19 pandemic studies are still popular in both academia and the industry, and cruise industry trends and market investigations are expected by consumers and investors. The purpose of this study is to investigate the US cruise market and provide a comprehensive market overview for 2022, especially regional comparisons of consumer perceptions. This study identified consumers' preferences, including cruise duration, cruise line, travel season, and travel experience. Regional impacts were assessed by comparing the Agreement scores, and the southern region's residents show higher intention and a more positive attitude toward cruise travel. Finally, theoretical and managerial implications, limitations, and future research directions are discussed.

The purpose of this study was to investigate the corrosion of rusted carbon steel in dilute NaCl solution, with the purpose of exploring the effect of the rust layer on metal corrosion and establishing a corrosion model for rusted iron.

The corrosion behavior of rusted carbon steel in dilute NaCl solution was studied by means of weight-loss determinations, scanning electron microscopy, Raman spectrometry and electrochemical techniques.

The results indicated that carbon steel had a similar corrosion behavior in all three NaCl solutions. The iron rust, which consisted of a thin γ-FeOOH layer and a thick Fe₃O₄ layer, can facilitate the corrosion process of carbon steel via reduction of γ-FeOOH and the large area cathode of Fe₃O₄. Hence, the corrosion rate of carbon steel was accelerated significantly and finally was determined by the limiting diffusion rate of oxygen.

A corrosion model of rusted carbon steel was established, suggesting that iron rust formed in all slightly acidic waters with low alkalinity probably promotes the corrosion of carbon steel. Anti-corrosion measures for iron in this type of solution, such as desalination water, should be aimed to reduce the promotional effect of the rust layer on metal corrosion.
