    Accessible urban by modeling the explicit data using fuzzy logic
    (ACM, 2017) Daniel Sinkonde; Leonard Mselle; Nima Shidende; Sara Comai; Matteo Matteucci
    The paper explores the level of accessibility for people with specific mobility problems in an urban setting. The work is part on the polisocial Maps for Easy Path (MEP) project [1]. The project aiming at developing a set of innovative tools and solutions for the enrichment of geographical maps with information about accessibility of urban pedestrian areas for people with mobility challenges. This paper builds a FuzzyMEP predictive model that accounts for uncertainty in the real world using fuzzy logic to predict the quality and the condition of the accessibility of a path. The FuzzyMEP model has been developed for mapping two explicit data sets, namely the coordinates where a picture of an obstacle on the sidewalk has been taken and the comment. The current urban city accessibility tool uses spatial data and focuses mainly on the accessibility of a path. We present a novel MEP tool by using a fuzzy logic model for pedestrian path prediction of the condition of the accessibility of a path. In this paper, the FuzzyMEP model has been developed by applying a fuzzy logic rule which can be adapted to other contexts.

    Human Factors Analysis for Interactive Communication Systems Design in Higher Learning Institutions
    (Elsevier BV, 2022) Anthony Mwombeki; Nima Shidende; Leonard Mselle
    Over recent years, designers have encountered several challenges on how to capture and analyze human factors needed for effective design of interactive systems. In most cases, much effort is kept on functional requirements fulfilment with human factors aspects being given limited consideration. This study noticed persisting communication challenges in Tanzania's higher learning institutions. Lack of suited human factors frameworks was found to complicate the effective design of interactive communication systems. Authors qualitatively analyzed human factors needed in interactive communication systems design process. Based on that analysis, and following a thorough user centred design process, a four phase design science research methodology was employed to develop a human factors framework for interactive communication systems’ design in higher learning institutions. Building on the developed framework, the paper discusses its capabilities in guiding the design of interactive communication systems by focusing on both organizational as well as human aspects of the design. This paper provides a human factors analytical framework under design science research with activity theory complementing design science techniques. This approach is suited to conduct research on human factors analysis for interactive systems and pave the way for future human-centric research on human factors investigation in information systems design.
