Security of m-learning system : a collective responsibility

Innovation in learning technologies and services is driven by demands from Higher Educational Institutions (HEIs) in order to meet their students’ needs and make knowledge delivery easier. The technology could play a pivotal role in extending the possibilities for teaching, learning, and research in educational institutions. M-learning emerged from this innovation as a result of an unprecedented explosion in the number of mobile devices due to availability and affordability of mobile phones, smartphones and tablets among students. Competition in the mobile device industry is also encouraging developers to be innovative, constantly striving to introduce new features. Consequently, newer sources of risks are being introduced in the mobile computing paradigm at manufacturing level. Similarly, many m-learning promoters and developers focus on developing and delivering learning content and infrastructure for m-learning system without adequate consideration for security of stakeholders’ data, whereas the use of these mobile technologies for learning poses a serious threat to confidentiality, integrity and privacy of those involved in teaching and learning, yet traditional security threats are also evolving. Against this backdrop, the stakeholders in education sector (i.e. education providers, educators, m-learning promoters and developers) should begin to consider the security implications of these devices in modern teaching and learning environments. The purpose of this paper is to identify the m-learning security issues that stakeholders may face, how they are being affected by the security threats, who among is stakeholders are affected or most affected by security issues in m-learning using three Nigeria universities as case studies and what are the responsibilities of the stakeholders in ensuring risk free m-learning

Direct combination: a new user interaction principle for mobile and ubiquitous HCI

Direct Combination (DC) is a recently introduced user interaction principle. The principle (previously applied to desktop computing) can greatly reduce the degree of search, time, and attention required to operate user interfaces. We argue that Direct Combination applies particularly aptly to mobile computing devices, given appropriate interaction techniques, examples of which are presented here. The reduction in search afforded to users can be applied to address several issues in mobile and ubiquitous user interaction including: limited feedback bandwidth; minimal attention situations; and the need for ad-hoc spontaneous interoperation and dynamic reconfiguration of multiple devices. When Direct Combination is extended and adapted to fit the demands of mobile and ubiquitous HCI, we refer to it as Ambient Combination (AC) . Direct Combination allows the user to exploit objects in the environment to narrow down the range of interactions that need be considered (by system and user). When the DC technique of pairwise or n-fold combination is applicable, it can greatly lessen the demands on users for memorisation and interface navigation. Direct Combination also appears to offers a new way of applying context-aware information. In this paper, we present Direct Combination as applied ambiently through a series of interaction scenarios, using an implemented prototype system
