	abstract = {Transcription tasks have been long used as the de-facto evaluation method in mobile text entry research. Evaluations use memorable phrase sets, in order to prevent participants from devoting more attention to the stimulus phrase than the bare minimum. We present evidence from an eye-tracking study, demonstrating that the attention devoted to the stimulus phrase is much higher than might be expected. In fact, attention to the stimulus phrase takes up almost 50\% of participant attention spent outside the keyboard area, and overall 25\% of participant attention throughout any single transcription task. We explore a modification to the transcription task aimed at reducing this level of visual attention, without finding any statistically significant differences. These findings raise important questions on the continued use of the transcription task as the mainstream evaluation method for mobile text entry research.},

	abstract = {Cyber Physical Systems (CPS) combine computational and physical components enabling real world interaction. Digitization, decentralization and high connectivity as well as incorporation of various enabling technologies raise various security issues. These security concerns may affect safety, endangering as- sets and even human lives. This is especially true for CPS utilization in different sectors of great significance, including manufacturing or critical infrastructures, creating a need for efficiently handling relevant security issues. Including security as part of a software intensive technical system (i.e the CPS) that can be distribut- ed and highly resilient highlights the need for appropriate security methodologies to be applied on the CPS from the engineering stage during CPS design. The effi- cient security related processes that are implemented at design time, have an im- pact on security monitoring during the CPS operational phase (at run time). Effi- cient and accurate security monitoring that follows security-by-design principles can be a potent tool in the hands of the CPS manager for detecting and mitigating cyber threats. Monitoring traffic and activity at the system boundaries, detecting changes to device status and configuration, detecting suspicious activity indicating attacks, detecting unauthorized activity that is suspicious or violates security poli- cies, timely responding to security incidents and recovering from them, are issues that need to be efficiently tackled with by security monitoring. In the present chap- ter, we are exploring the various CPS cybersecurity threats and discus how adding security as a parameter at the CPS design phase can provide a well-structured and efficient approach on providing strong security CPS foundations. New technolo- gies on CPS security Design are presented and emerging security directions are discussed. Furthermore, in the chapter, the different aspects of security monitoring are presented with a special emphasis on CPSs, discussing the various existing monitoring approaches that are followed in order to detect security issues at run time. Specific use-cases of CPSs in the manufacturing domain and with reference to critical infrastructures are also detailed and security requirements like confiden- tiality, integrity and availability are discussed},

Privacy-preserving semantic labelling of a user{\textquoteright}s location can be useful for the contextually-relevant handling of interruptions and service delivery on mobile device},

	abstract = {Over the last few years, there is increasing adoption of distance learning methods in various aspects of education. As part of our research in digital distance learning platforms, we conducted longitudinal observations and a survey on the use of web 2.0 tools in adult education and found that 32\% of the students who used such technology, were doing so through mobile devices. Motivated by the students{\textquoteright} use of mobile platforms as learning tools, the aim of this paper is to explore the context under which studying takes place for distance learning students, in order to gain a better understanding of existing practices, with a view of supporting and improving learning experiences through pervasive computing. For this, we started a process of collecting qualitative and quantitative data in order to find out more information about their study context. Our findings from the collected data are paired with post-collection period interviews, providing a quantitative and qualitative description of the context under which distance learning takes place.},
