User-centered design of a dynamic-autonomy remote interaction concept for manipulation-capable robots to assist elderly people in the home
In this article, we describe the development of a human-robot interaction concept for service robots to assist elderly people in the home with physical tasks. Our approach is based on the insight that robots are not yet able to handle all tasks autonomously with sufficient reliability in the complex and heterogeneous environments of private homes. We therefore employ remote human operators to assist on tasks a robot cannot handle completely autonomously. Our development methodology was user-centric and iterative, with six user studies carried out at various stages involving a total of 241 participants. The concept is under implementation on the Care-O-bot 3 robotic platform. The main contributions of this article are (1) the results of a survey in form of a ranking of the demands of elderly people and informal caregivers for a range of 25 robot services, (2) the results of an ethnography investigating the suitability of emergency teleassistance and telemedical centers for incorporating robotic teleassistance, and (3) a user-validated human-robot interaction concept with three user roles and corresponding three user interfaces designed as a solution to the problem of engineering reliable service robots for home environments
Investigating the appropriateness and relevance of mobile web accessibility guidelines
The Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C) develop and maintain guidelines for making the web more accessible to people with disabilities. WCAG 2.0 and the MWBP 1.0 are internationally regarded as the industry standard guidelines for web accessibility. Mobile testing sessions conducted by AbilityNet document issues raised by users in a report format, relating issues to guidelines wherever possible. This paper presents the results of a preliminary investigation that examines how effectively and easily these issues can be related by experts to the guidelines provided by WCAG 2.0 and MWBP 1.0.

Interactive Reading Using Low Cost Brain Computer Interfaces
This work shows the feasibility for document reader user applications using a consumer grade non-invasive BCI headset. Although Brain Computer Interface (BCI) type devices are beginning to aim at the consumer level, the level at which they can actually detect brain activity is limited. There is however progress achieved in allowing for interaction between a human and a computer when this interaction is limited to around 2 actions. We employed the Emotiv Epoc, a low-priced BCI headset, to design and build a proof-of-concept document reader system that allows users to navigate the document using this low cast BCI device. Our prototype has been implemented and evaluated with 12 participants who were trained to navigate documents using signals acquired by Emotive Epoc

Age related cognitive impairments and assistive web-base technology
Several researchers argue that age related cognitive impairments have detrimental affect on use of web services by older adults. However little and systematic applied research has been conducted on how age related cognitive impairments might affect the usage of web services by older adults. Undoubtedly, understanding the relationship between the cognitive changes that accompany aging and their impact on older adultsā usage of web services will be beneficial for designing web services for this group. The paper demonstrates how such understanding has been employed to develop an assistive technology in order to improve older adultsā interaction with online forms
A Phone Learning Model for Enhancing Productivity of Visually Impaired Civil Servants
Phone-based learning in civil service is the use of voice technologies to deliver learning and capacity building training services to
government employees. The Internet revolution and advancement in Information and Communications Technology (ICT) have given rise
to online and remote staff training for the purpose of enhancing workers productivity. The need for civil servants in Nigeria to develop
capacity that will enhance knowledge is a key requirement to having competitive advantage in the work place. Existing online learning
platforms (such as web-based learning, mobile learning, etc) did not consider the plight of the visually impaired. These platforms provide
graphical interfaces that require sight to access. The visually impaired civil servants require auditory access to functionalities that exist in
learning management system on the Internet. Thus a gap exist between the able-bodied and visually impaired civil servants on
accessibility to e-learning platform. The objective of this paper is to provide a personalized telephone learning model and a prototype
application that will enhance the productivity of the visually impaired workers in Government establishments in Nigeria. The model was
designed using Unified Modeling Language (UML) diagram. The prototype application was implemented and evaluated. With the
proposed model and application, the visually and mobility impaired worker are able to participate in routine staff training and
consequently enhances their productivity just like their able-bodied counterparts. The prototype application also serves as an alternative
training platform for the able-bodied workers. Future research direction for this study will include biometric authentication of learners
