Ontology for Mobility of People with Intellectual Disability: Building a Basis of Definitions for the Development of Navigation Aid Systems

Abstract: Being able to move independently is a skill that seems necessary for social inclusion and participation. However, people with intellectual disabilities often face difficulties in developing autonomous mobility. Similarly, existing mobile navigation aid systems, which could help them to move from one place to another, are not adapted to their cognitive specificities. The purpose of this paper is to present an ontology of spatial navigation established to serve as a basis for the development of mobility aid systems adapted to people presenting an intellectual disability. It presents the method used to create the ontology, a representative extract of the ontology obtained and an illustration of the use of the ontology for the development of a mobility aid system. The limitations of the ontology and future work are also discussed.

RFID-based tangible and touch tabletop for dual reality in crisis management context

Abstract: Robots are becoming more and more present in many domains of our daily lives. Their usage encompasses industry, home automation, space exploration, and military operations. Robots can also be used in crisis management situations, where it is impossible to access or dangerous to send humans into the intervention area. The present work compares users’ performances on tangible and on touch user interfaces, for a crisis management application on tabletop. The studied task consists of remotely controlling robots in a simulated disaster/intervention area using a tabletop equipped with a layer of RFID antennas, by displacing mini-robots on its surface matching the situation of the real robots on the ground. Dual reality enforces an accurate and up-to-date mapping between the real robots and the mini robots on the tabletop surface. Our findings show that tangible interaction outperforms touch interaction in effectiveness, efficiency and usability, in a task of remote control of one and two robots; only when the user manipulates a single robot remains the efficiency dimension unchanged between tangible and touch interaction. Results also show that tangible interaction technique does not significantly lower the users’ workload. We finally expose a post-experiment interview and questionnaire results, assessing the participants’ overall satisfaction and agreement on using tangible objects on a tabletop.

The use of task modeling in interactive system specification

Abstract: Task modeling is undoubtedly a key step for task analysis during the development of iterative systems since it helps not only in the understanding of what users want but also in how to design for them. As a consequence, it should be considered as indispensable while specifying the requirements of an interactive system. With this in mind, we analyzed the requirement specifications of a typical interactive system which is a compulsory element of the final grade for a human–computer interaction course in two Master’s degree programs at the University of Valenciennes. To that end, we decided to use an approach based on project-based learning. Sixty-three requirement specifications performed since 2010 were investigated to find out how the task modeling was represented. Moreover, suggestions concerning pedagogical improvement made by the students in an open question on the evaluation form were analyzed using the ground theory method. The results showed that since students are not required to perform task modeling by the requirement specification, they do not do so even in the case of complex interactive systems. Criticism, positive and improvement issues raised by the students were also identified. In this paper, we present a detailed analysis of this study that opens up questions about HCI education and effective learning of task modeling, and, as a consequence, its potential use in industry.

An analysis of MoLIC's consolidation

Abstract: MoLIC is a language for modeling human-computer interaction as a conversation that is grounded on Semiotic Engineering theory. It was proposed as an epistemic tool aimed at supporting designers in thinking about and making decisions regarding the designer-to-user communication being conveyed through the system-user communication. In this paper, our goal is to investigate how consolidated MoLIC is since it was first published in 2003. We have carried out a Systematic Literature Review and analyzed how MoLIC has been used by the HCI community, considering how it has been used over the years, the number of authors that reference or use it, forums in which works have been published, as well as the main contributions of the research about it. Our results indicate that MoLIC is well consolidated, as it has been broadly used and studied by national and international authors. The existing version is stable and researchers are interested in applying it to system modeling or to investigate extensions and other aspects related to its use.

A Review of Human-Computer Interaction Design Approaches towards Information Systems Development

Abstract: Nowadays modern information systems (emerging technologies) are increasingly becoming an integral part of our daily lives and has begun to pose a serious challenge for human-computer interaction (HCI) professionals, as emerging technologies in the area of mobile and cloud computing, and internet of things (IoT), are calling for more devotion from HCI experts in terms of systems interface design. As the number of mobile platforms users, nowadays comprises of children’s, elderly people, and people with disabilities or disorders, all demanding for an effective user interface that can meet their diverse needs, even on the move, at anytime and anywhere. This paper, review current articles (43) related to HCI interface design approaches to modern information systems design with the aim of identifying and determining the effectiveness of these methods. The study found that the current HCI design approaches were based on desktop paradigm which falls short of providing location-based services to mobile platforms users. The study also discovered that almost all the current interface design standard used by HCI experts for the design of user’s interface were not effective & supportive of emerging technologies due to the flexibility nature of these technologies. Based on the review findings, the study suggested the combination of Human-centred design with agile methodologies for interface design, and call on future works to use qualitative or quantitative approach to further investigate HCI methods of interface design with much emphasis on cloud-based technologies and other organizational information systems.
