Radbeacon x25/18/2023 ![]() As a step towards solving this problem, we propose a solution supporting the navigation of users, especially the visually impaired, inside buildings. As satellite navigation systems are burdened with errors, which increase when trying to use them in confined spaces, it becomes necessary to use more accurate technology. Because as the urbanisation process, the surfaces of various buildings grow, which significantly impedes orientation in them, especially for the blind or visually impaired users. A similar revolution may also await navigations in closed spaces such as public or commercial buildings. Nowadays people cannot imagine moving in an "urban jungle” with paper maps without electronic support, but dozens of years ago those maps were more popular than satellite navigation. Thanks to the use of satellite positioning systems (including GPS) the ability to determine a user's position in open spaces has become a necessary element of everyday life. It can also be utilized to monitor construction productivity by categorizing and locating the machinery-related sound sources. The system can categorize an accidental or abnormal sound and locate the sound source for safety management at the construction site. Furthermore, CSLF is applicable on the sound data categorization-related research. These results show that the CSLF can effectively identify sound locations at construction sites within an arm’s length. The exterior tests conducted at an actual construction site showed average x-, y-, and z-axis errors of 0.19, 0.21, and 0.24 m, respectively. The interior tests showed that the average error was less than 0.5 m for each axis which is 0.26, 0.27, and 0.36 m for the x-, y-, and z-axes, respectively. Verification tests were performed on the CSLF in both interior and exterior environments. Based on the spatial characteristics of construction sites, this study identified sound-source locations at construction sites to overcome the limitations of existing sensor-based localization methods. ![]() This study developed a construction sound localization framework (CSLF) using the time delay of the arrival technique and the generalized cross-correlation phase transform. Conclusions reached argue that off-the-shelf GPS devices are a viable, inclusive alternative to ‘dementia branded’ products, that could reduce healthcare inequalities and increase access to potentially vital technology. The approach taken provided new insights into conducting research with people living with dementia as well as during times of crisis. This study demonstrates the benefits of GPS in relation to a person’s psycho-social needs, with barriers found relating to a person’s relationship with technology. In-depth interviews with participants took place before and after this period of use.įindings resonate with existing research, but also build upon the evidence base, to show the benefits and challenges of using this technology. Phase two utilised these findings with eighteen new participants using the off-the-shelf device chosen by participants of phase one, alongside training and technical support, for a period of three months. Findings indicated that the wearability, usability, and cost of products were integral to their success and adoption. ![]() The first phase acted as a consultation session, employing a focus group to explore the views, opinions, and experiences of participants living with dementia and care partners on a range of off-the-shelf GPS devices. ![]() This was done through a two-phased approach. This was not research ‘about them’, or through the use of a proxy to explore what people with dementia might do instead, this research sought to ensure that their voice was heard, understood, and had an impact. This study was designed to guarantee that people living with dementia were an essential part of the study. ‘Off-the-shelf’ GPS devices are readily available, without a specific use attached and are often more economical than products labelled for use within dementia care. This doctoral thesis explores the perceptions and experiences of people living with dementia and their care partners on off-the-shelf Global Positioning System (GPS) technology.
