Since the launch of the first consumer grade EEG measuring sensors ‘NeuroSky Mindset’ in 2007, the market has witnessed an introduction of at least one new product every year by competing manufacturers, which include NeuroSky, Emotiv, interaXon and OpenBCI. There are numerous variations in the make and versions, but these products clearly share the key selling points of affordability, portability, and ease of use. These features are patently well placed provided one of the main objectives for their development is to attract a new target group of commercial users. Nevertheless, with several decades of traditional EEG usage in clinical and experimental settings, the shift toward commercial and engineering sides has not been achieved without skepticism. With this in mind, researchers in related fields have been tirelessly working to ensure that these putatively novel features were not introduced at the expense of efficiency and accuracy by conducting validation studies to compare the performance of data derived from consumer grade EEG devices with ones from standard research grade counterparts. In this review, we seek to provide the detail of the products supplied by the major players, summarize studies that evaluate consumer product’s performance against research grade devices, the key areas of applications that these consumer grade devices have been employed in over the past five years or so, and finally give our perspectives on the limitations and what these innovative tools could offer going forward in terms of research and commercial applications.

Consumer Grade EEG Measuring Sensors as Research Tools: A Review

Includes a Thematic Synthesis of the awareness interpretations defined so far.No interpretation can deal with the awareness needs of collaborative games.The Gamespace Awareness interpretation for collaborative games is defined.Workspace Awareness was used as the main foundation of our integrated solution. ContextCollaborative computer games have evolved from single-player to massively multiplayer awareness-demanding games, usually involving collaboration to achieve team goals. As a consequence of such evolution, these players should be provided with awareness information that enables them to perform collaborative tasks with other team members. ObjectiveThe objective of this work is the analysis of current awareness interpretations in order to develop an awareness interpretation that collects the awareness needs of such games. MethodThis analysis has been conducted by means of a step-by-step Thematic Analysis of current interpretations that led us to extract the most relevant awareness elements defined in existing interpretations. The developed awareness interpretation was empirically evaluated by means of several surveys aimed at assessing whether the implementation of the interpretation elements in a game would improve the players enjoyment. ResultsThe Thematic Synthesis Analysis concluded that none of the current awareness interpretations can deal properly with collaborative computer games, specifically due to collaboration and social & group dynamics. This Thematic Synthesis Analysis led us to coin Gamespace Awareness, a new awareness interpretation based on a combination of the previously analyzed awareness interpretations, which is suitable for collaborative computer games. The interpretation was positively evaluated for two games, namely a first person shooter and a real-time strategy game. ConclusionsGamespace Awareness combines the potential awareness elements needed for collaborative computer games, making it possible to identify the awareness requirements of these games from the very beginning.

Applying thematic analysis to define an awareness interpretation for collaborative computer games

Context: A collaborative system is a special kind of software whose users can perform collaboration, communication and collaboration tasks. These systems usually have a high number of non-functional requirements, resulting from the users' need of being aware of other users with whom to collaborate, that is, the workspace awareness. Objective: This paper aims at evaluating two Requirements Engineering languages i^* and CSRML (an extension of i^*) in order to determine which is the most suitable one to specify requirements of collaborative systems, taking into account their special characteristics regarding collaboration and awareness. Method: We performed a family of experiments comprising an original experiment and two replicas. They were performed by 30, 45 and 9 Computer Science students, respectively, from Spain and Argentina. These subjects filled in two understandability questionnaires once they analyzed the requirements models of two systems: an e-learning collaborative system and a conference review system with some collaborative aspects support. Both models were specified by using the evaluated languages. Results: The statistical analysis of the family of experiments showed that the understandability was higher for the models specified with CSRML than for those specified with i^*, especially for collaborative aspects. This result was also confirmed by the meta-analysis conducted. Conclusions: CSRML surpasses i^* when modeling collaborative systems requirements models due to the specific expressiveness introduced to represent collaboration between users and awareness and the new resorts to manage actors and roles.

A collaborative system is software which allows several users to work together and carry out collaboration, communication and coordination tasks. To perform these tasks, the users have to be aware of other user's actions, usually by means of a set of awareness techniques. In previous works, we found by means of empirical studies that the most suitable Requirements Engineering approach to specify the requirements of this kind of systems is the Goal-Oriented one, and more precisely i* approach. In this paper, CSRML (Collaborative Systems Requirements Modelling Language) is presented, an extension of i* to deal with the specification of the requirements of these systems in which the collaboration and the awareness of other users presence / actions are crucial. In order to validate this proposal, a case study has been carried out by modelling a jigsaw activity: a cooperative-learning technique in which students individually do some research in a proposed problem and then they teach each other what they have learned by sharing each individual view of the problem.

CSRML: a goal-oriented approach to model requirements for collaborative systems

Context CSRML Tool 2012 is a Requirements Engineering CASE Tool for the Goal-Oriented Collaborative Systems Requirements Modeling Language (CSRML). Objective This work aims at evaluating the usability of CSRML Tool 2012, thus identifying any possible usability flaw to be solved in the next releases of the application, as well as giving a general overview on how to develop a DSL tool similar to the one evaluated in this work by means of Visual Studio Modelling SDK. Method In this evaluation, which was reported by following the ISO/IEC 25062:2006 Common Industry Format for usability tests, 28 fourth-course Computer Science students took part. They were asked to carry out a series of modifications to an incomplete CSRML requirements specification. Usability was assessed by measuring the task’s completion rate, the elapsed time, number of accesses to the help system of the tool and the instructor’s verbal assistance. The participants’ arousal and pleasantness were assessed by analyzing both facial expressions and a USE questionnaire. Results In spite of obtaining high usability levels, the test outcome revealed some usability flaws that should be addressed. Conclusion The important lessons learnt from this evaluation are also applicable to the success of other usability tests as well as to the development of new CASE tools.

Fostering sustainability is paramount for Smart Cities development. Lately, Smart Cities are benefiting from the rising of Big Data coming from IoT devices, leading to improvements on monitoring and prevention. However, monitoring and prevention processes require visualization techniques as a key component. Indeed, in order to prevent possible hazards (such as fires, leaks, etc.) and optimize their resources, Smart Cities require adequate visualizations that provide insights to decision makers. Nevertheless, visualization of Big Data has always been a challenging issue, especially when such data are originated in real-time. This problem becomes even bigger in Smart City environments since we have to deal with many different groups of users and multiple heterogeneous data sources. Without a proper visualization methodology, complex dashboards including data from different nature are difficult to understand. In order to tackle this issue, we propose a methodology based on visualization techniques for Big Data, aimed at improving the evidence-gathering process by assisting users in the decision making in the context of Smart Cities. Moreover, in order to assess the impact of our proposal, a case study based on service calls for a fire department is presented. In this sense, our findings will be applied to data coming from citizen calls. Thus, the results of this work will contribute to the optimization of resources, namely fire extinguishing battalions, helping to improve their effectiveness and, as a result, the sustainability of a Smart City, operating better with less resources. Finally, in order to evaluate the impact of our proposal, we have performed an experiment, with non-expert users in data visualization.
