Abstract
Despite being the most comprehensive model so far for capturing the factors contributing to disability, the International Classification of Functioning, Disability, and Health (ICF) developed by the World Health Organization does not recognize a set of time concepts that are relevant to activity engagement as contextual factors. The unrecognized time concepts (i.e., available time and required time) interact with one’s body functions and other ICF components (e.g., environmental factors) to affect one’s engagement in activities and participation. As a result, the ICF model failed to identify the challenges related to time that limit one’s activity engagement and could not facilitate the design of technologies that address those challenges for individuals with disabilities. This dissertation project presents a design case study about the design and evaluation of a travel planning mobile application named ALIGN 2.0. The design case study aims to provide primary research evidence to support the inclusion of temporal factors in the ICF model (i.e., the modified ICF model). The ALIGN 2.0 app was designed and evaluated according to the proposed modified ICF model to facilitate the management of time-related challenges faced by travelers with mobility impairments. Specifically, different types of travel information provided in ALIGN 2.0 were designed to reflect the various interactions/pathways between temporal factors and other ICF components and were evaluated for their effects on travel time allocations by travelers with mobility impairments. The evaluation outcome supported the existence of the pathways in the modified ICF model thus serves as evidence for supporting the inclusion of temporal factors in the ICF model. The direct outputs of this project are the designed ALIGN 2.0 app and the modified ICF model that includes temporal factors as additional contextual factors. The outcome of this project is the recognized role of time in activity engagement and its interactions with other components within the existing ICF model.
