This dissertation is part of the Human-Computer Interaction (HCI) field of studies concerning the challenges, the technological solutions developed to enable sensory disabled and marginalized groups of individuals and the effective training methodological approaches. The ultimate goal of this effort is to contribute towards the direction of reducing social exclusion and the stigma associated with disabled individuals.In more detail, this effort focuses on enabling independent navigation in both outdoor and indoor spaces via assistive technology (AT) solutions that takes into consideration the special needs of the blind and visually impaired and considers the design of training sessions as an important factor for the success of any AT solution. Blind people face serious restrictions in their life due to their vision impairment resulting in both social and professional exclusion and a deteriorated quality of life. There are a lot of individuals worldwide suffering from eyesight deficiencies and a large amount is found in low to middle-income countries creating additional challenges for any solution. Taking all this into consideration the initiative for the MANTO project was created involving the design, implementation and validation of AT solutions for providing cost and functionally effective indoor and outdoor blind navigation applications.The design phase involved the conduct of multiple interviews with the blind and visually impaired, where various categories of beliefs, attitudes and preferences emerged after a thorough analysis of the given input. Among the many categories, the most significant ones were selected to form the requirements concerning the functionality and interface provided by the two applications targeting outdoor and indoor navigation. The involvement of the blind and visually impaired individuals was critical to the applications' development cycle as dictated by the followed user-centered design approach. Taking into consideration the input of the requirements elicitation phase and the overall goals for cost and functional effectiveness, both applications were built on top of the Android platform utilizing low-end smartphone devices.Regarding the case of outdoor space navigation, the application provides safe and highly precise blind pedestrian navigation without requiring the mandatory use of tactile ground surface indicators. The system employs voice instructions to continuously inform the user about the status and progress of the navigation and the various obstacles found along the navigational path. The Android application (BlindRouteVision) aggregates data from three different sources, an external high-precision GPS receiver tracking real-time pedestrian mobility, a custom-made external device consisting of an ultra-sonic sensor and a servo mechanism that resembles a sonar device in its functionality and, finally, a second external device installed on traffic lights for tracking their status in order to enable the passing of crossings near them. The user interacts with the system via an appropriately designed voice interface to enable fast and accurate interaction. Likewise, for the case of indoor space navigation, the application provides accurate and safe navigation in indoor spaces.
