Individuals with disability (e.g. visual impaired) are unique in their own ways. Existing solutions are often inadequate in effectively assisting them in their need. Assistive thinking is a paradigm shift in the design and implementation of intelligent technology solutions for individuals with visual impairment or blindness, which can be applied in other disabilities. It calls for an in-depth analysis of a user's need as well as preference, estimate the cognitive ability-vs-demand gap from user's mental effort, and integrate user requirements using design and systems thinking ideas into the assistive technology (AT) systems. In addition, it advocates an effective use of existing resources in managing disability with a sustainability plan to maximize the utility of technology solutions with adaptive user interaction. This is expected to transform the design, implementation, and use of assistive systems that not only meet users' needs, but also address their situational and social needs. This paper presents the culminating experiences of designing assistive systems and a pilot study that was performed using a set of usability questions and observed cognitive capabilities of representative users, the persons who are blind or visual impaired. Assistive thinking considers a user's activity pattern based on the interface design pattern, analyzes cognitive load during technology interaction, communicate directly to technology and generate feedback to the user. It also addresses the user's unintended consequences that may cause failure and facilitates subsequent modeling to improve technology performance resulting both accessible and useable interfaces for people with disabilities.

Abstract-Framing Internet of Things (IoT) applications as a System of Systems (SoS) can help us make sense of complexity associated with interoperability and emergence. However, assessing the risk of SoSs is a challenge due to the independence of component systems, and their differing degrees of control and emergence. This paper presents three components for SoS risk assessment that integrate with existing risk assessment approaches: Human System Integration (HSI), Interoperability identification and analysis, and Emergent behaviour evaluation and control measures. We demonstrate the application of these components by assessing a pervasive SoS: a SmartPowerchair.

“…The framework has been applied to the SmartPowerchair SoS described in [3] by considering the mappings between disability type, Range of Movement (ROM), interaction mediums, technologies and tasks. It is a recommender system that uses physical impairments and ROM characteristics to suggest technologies to assist people with disability to perform daily tasks.…”

Abstract-This paper introduces the SmartDisability Framework; a System of Systems to consider mappings between the Disability Types, Range of Movement and Interaction Mediums to produce Technology and Task recommendations. Each element is seen as a constituent system that relies on interaction between the user and technology. The recommended technologies are viewed as independent and operable constituent systems that are networked together to assist people with disability. The SmartDisability conceptual model (based on the familiar disability symbol) and extracts from the initial development stage of the framework are presented. The framework has been populated through a systematic literature review of disability classification, Range of Movement, interaction mediums, 'off-the-shelf' technologies and tasks. The framework was augmented by the results of a previously conducted requirements elicitation process, involving surveys and semi-structured interviews, and a user evaluation with head tracking technology. Quality Function Deployment determined the relationships within the framework to ensure that user requirements were fully analysed. The anticipated validation process involving a focus group utilising fictional personas and routes to exploitation (through the development of an application) are also discussed.
