Download or read book An IOS Based Indoor Wayfinding Application for People with Navigational Disabilities written by Taha Hasan Syed and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Navigation has become an integral part of today's society. Many people use devices such as smartphones to get direction in and out of unfamiliar environments. People have come to rely on these devices as it helps them get to their destination with ease. However, there are limitations when it comes to navigating indoors when compared to outdoors. The technology used for outdoor navigation becomes inaccurate when it comes to indoor navigation. The problem escalates when people with navigation impairments such as blindness or mobility impairment are unable to follow a route to get to their destination that's indoors. Such unreliability causes inconvenience and losses to clients. This thesis showcases a navigation application using called CityGuide which is an iOS based indoor way finding solution that can help people navigate indoor environments with ease. The application targets accessibility groups such as people with visual impairments and people with mobility impairment, by providing them with a rich user experience while it tries to direct them to their destination. The project uses a localized server in order to have complete control over the data being transferred to and from the application making the app more independent and the hardware installation cheaper for the long term. The app uses algorithms and approaches to find the shortest path to the destination and also applies additional features such as haptic feedback, re-routing function, instructional dictation of the path and by being voice over friendly. The navigation model introduced is reliable, cheap, and easy to install and allows organizations to implement better accessibility features in their indoor space.

Download or read book Indoor Navigation Technology Exploration and Application in University Buildings written by Sushmit Sharma Bhattarai and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As commercial and industrial buildings are so complex, navigating inside of those buildings, findings rooms, and exits has become difficult, especially for the those who are new to the building. To overcome these difficulties, this research project is related to indoor navigation or wayfinding. Different technologies such as Wi-Fi positioning, Bluetooth, low energy beacon, ultrasonic, infrared, semantic maps, building information modeling, and augmented reality has been applied for indoor navigation due to the unavailability of global positioning system, which is extensively used in outdoor navigation. The purpose of this research is then to explore the literature of indoor navigation technologies, uses of as-built 3D scan use in indoor navigation, and to develop a prototype application by using as-built 3D scans to assist users who are new to the building and want to locate facilities. For example, finding the restroom or nearest exit-way in case of emergency. In this research, the prototype application is based on a 3D scan of the Roy F. Mitte (RFM) building. The research presents the results of the perception of students who visit the RFM building to evaluate if indoor navigation technology could assist them in navigating based on their facility needs. This research uses a mixed method to explore, analyze the data, and discuss the findings. This research also examines the potential of 3D scans and digital twins for use in emergency evacuation procedures inside of buildings. To fulfil the objectives of this research, the author used a Faro Laser scanner and scanned an as-built indoor hallway of the RFM building. Due to limitations, the author used the fourth floor of RFM building for the prototype development. The author collected 3D point clouds and converted them to mesh and generated an area target using Vuforia engine. Finally, the author exported the mesh model and area target to the Unity application to develop a prototype indoor navigation application using Vuforia engine and Unity.

Download or read book Indoor Positioning and Navigation written by Simon Tomazič and published by Mdpi AG. This book was released on 2021-11-12 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, rapid development in robotics, mobile, and communication technologies has encouraged many studies in the field of localization and navigation in indoor environments. An accurate localization system that can operate in an indoor environment has considerable practical value, because it can be built into autonomous mobile systems or a personal navigation system on a smartphone for guiding people through airports, shopping malls, museums and other public institutions, etc. Such a system would be particularly useful for blind people. Modern smartphones are equipped with numerous sensors (such as inertial sensors, cameras, and barometers) and communication modules (such as WiFi, Bluetooth, NFC, LTE/5G, and UWB capabilities), which enable the implementation of various localization algorithms, namely, visual localization, inertial navigation system, and radio localization. For the mapping of indoor environments and localization of autonomous mobile sysems, LIDAR sensors are also frequently used in addition to smartphone sensors. Visual localization and inertial navigation systems are sensitive to external disturbances; therefore, sensor fusion approaches can be used for the implementation of robust localization algorithms. These have to be optimized in order to be computationally efficient, which is essential for realtime processing and low energy consumption on a smartphone or robot.

Download or read book Navigation Instruction Validation Tool and Indoor Wayfinding Training System for People with Disabilities written by Linlin Ding and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: According to World Health Survey, there are 785 million (15.6%) people in the world that live with a disability. It is a well-known fact that lack of access to public transportation is a barrier for people with disabilities in seeking work or accessing health care. In this research, we seek to increase access to public transportation by introducing a virtual pre-travel training system that enables people with disabilities to get familiar with a public transportation venue prior to arriving at the venue. Using this system, users establish a mental map of the target environment prior to their arrival to the physical space, increasing their confidence and therefore increasing their chances of using public transportation. First, we have to guarantee that all navigation instructions sent to our training system are correct. Since the number of navigation instruction increases dramatically, instruction validation becomes a challenge. We propose a video game based validation tool which includes a game scene that represents in 2D the physical environment and uses a game avatar to verify the navigation instructions automatically in the game scene. The avatar traverses the virtual space following the corresponding navigation instructions. Only in case that it successfully reaches the planned destination, the current navigation instruction can be considered as correct. Then, we introduce a virtual reality based pre-travel wayfinding training system to assist people with disabilities to get familiar with a venue prior to their arrival at the physical space, which provides two modes: 1) Self-Guided mode in which the path between a source and a destination is shown to the user from third person perspective, and 2) Exploration mode in which the user explores and interacts with the environment. In the end, we have implemented visual analytics tools that track and evaluate trainees' performance and help us optimize the game. These tools identify the difficulties faced by the trainees as well as obtain overall statistics on the trainees' behavior in the indoor environment, helping us understand how to modify the system and adjust it to different classes of disabilities.

Download or read book Indoor Semantic Modelling for Routing written by Liu By Liu and published by . This book was released on 2017 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans perform many activities indoors and they show a growing need for indoor navigation, especially in unfamiliar buildings such as airports, museums and hospitals. Complexity of such buildings poses many challenges for building managers and visitors. Indoor navigation services play an important role in supporting these indoor activities. Indoor navigation covers extensive topics such as: 1) indoor positioning and localization; 2) indoor space representation for navigation model generation; 3) indoor routing computation; 4) human wayfinding behaviours; and 5) indoor guidance (e.g., textual directories). So far, a large number of studies of pedestrian indoor navigation have presented diverse navigation models and routing algorithms/methods. However, the major challenge is rarely referred to: how to represent the complex indoor environment for pedestrians and conduct routing according to the different roles and sizes of users"

Download or read book Comprehensive Navigation Framework for Seniors and People with Disabilities written by Hao Dong and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Finding the path to a destination is an indispensable skill in our daily life. Thanks to the global navigation satellite system (GNSS), navigation systems such as Google Map facilitates this task very well for the uses of vehicle and pedestrian in outdoor environments. However, due to the lack of indoor localization solution, the navigation system for the indoor environment still remains in the realm of research. On the other hand, indoor wayfinding tasks become not trivial anymore, because of the intricate structure of modern buildings with vast information, especially for seniors and the visually impaired. In this dissertation, we introduce a navigation framework to provide an affordable solution to both the travelers and the venue providers. The framework provides a solution in two phases of an upcoming trip. The first phase is a Virtual Reality (VR) pre-travel training system allowing the travelers to learn the structure, functionalities, and necessary cues for wayfinding in the target environment prior to the physical visit. A novel approach to represent a virtual environment of the physical space was proposed and implemented in this system. It leverages a computer vision-based solution to Simultaneous Localization and Mapping (SLAM) to enable panoramic videos for immersive annotation in VR. Based on the performance tests in 3 different indoor environments, we show that the total preparation time to deploy this system in a new environment is proportional to the length of the recording path of panoramic videos at a rate of less than a minute per meter. This is a significant reduction compared to traditional 3D modeling approaches. While the cost savings are substantial, the framework enables the users to explore the virtual environment only along the recorded paths. The author envisions that this is sufficient for the purpose of learning an unfamiliar environment. The second phase is a wayfinding assistance system providing on-site guidance through a mobile application when the user arrives at the target building in person. This system can provide the user's current location and orientation, navigation instructions to a chosen destination, and other contextual information in the environment. The deployment process utilizes a Structure-from-Motion (SfM) pipeline to generate a spatial map for localization. The video recordings collected for the pre-travel training system can be reused as parts of the input in this process. With the performance tests in the three testing environments, it shows that in contrast to the pre-travel training system, the total processing time is approximately proportional to the coverage area. Every 3 square meters will take about 1 minute. A novel multi-layer graph-based data structure is also proposed and implemented to organize the building information and expedite the navigation instruction generation. A human trial with 9 participants using this system was also conducted in the Campus Center of the University of Massachusetts, Amherst.

Download or read book Cognition in the Wild written by Edwin Hutchins and published by MIT Press. This book was released on 1996-08-26 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edwin Hutchins combines his background as an anthropologist and an open ocean racing sailor and navigator in this account of how anthropological methods can be combined with cognitive theory to produce a new reading of cognitive science. His theoretical insights are grounded in an extended analysis of ship navigation—its computational basis, its historical roots, its social organization, and the details of its implementation in actual practice aboard large ships. The result is an unusual interdisciplinary approach to cognition in culturally constituted activities outside the laboratory—"in the wild." Hutchins examines a set of phenomena that have fallen in the cracks between the established disciplines of psychology and anthropology, bringing to light a new set of relationships between culture and cognition. The standard view is that culture affects the cognition of individuals. Hutchins argues instead that cultural activity systems have cognitive properties of their own that are different from the cognitive properties of the individuals who participate in them. Each action for bringing a large naval vessel into port, for example, is informed by culture: the navigation team can be seen as a cognitive and computational system. Introducing Navy life and work on the bridge, Hutchins makes a clear distinction between the cognitive properties of an individual and the cognitive properties of a system. In striking contrast to the usual laboratory tasks of research in cognitive science, he applies the principal metaphor of cognitive science—cognition as computation (adopting David Marr's paradigm)—to the navigation task. After comparing modern Western navigation with the method practiced in Micronesia, Hutchins explores the computational and cognitive properties of systems that are larger than an individual. He then turns to an analysis of learning or change in the organization of cognitive systems at several scales. Hutchins's conclusion illustrates the costs of ignoring the cultural nature of cognition, pointing to the ways in which contemporary cognitive science can be transformed by new meanings and interpretations.
