Gamification is a powerful paradigm and a set of best practices used to motivate people carrying out a variety of ICT-mediated tasks. Designing gamification solutions and applying them to a given ICT system is a complex and expensive process (in time, competences and money) as software engineers have to cope with heterogeneous stakeholder requirements on one hand, and Acceptance Requirements on the...
Humans are an integral entity for performing software quality and testing activities. The quality is compromised when human- thought process deviates from the laws of rational thinking, referred to as cognitive biases. The work carried out so far from this perspective in software quality and testing is very scarce and is limited to one cognitive bias only. This work aims to explore the phenomenon...
There is a broad consensus that understanding software requirements is critical in designing a good software system. Software engineering research literature is rife with state of the art practices and techniques that are proposed to improve requirements engineering techniques. Also, creative approaches are used to determine system requirements in a better way. However, little empirical research has...
In this project we propose a new approach for emotion recognition using web-based similarity (e.g. confidence, PMI and PMING). We aim to extract basic emotions from short sentences with emotional content (e.g. news titles, tweets, captions), performing a web-based quantitative evaluation of semantic proximity between each word of the analyzed sentence and each emotion of a psychological model (e.g...
At the current time, there are several fundamental changes in the way computing systems are being developed, deployed and used. They are becoming increasingly large, heterogeneous, uncertain, dynamic and decentralised. These complexities lead to behaviours during run time that are difficult to understand or predict. One vision for how to rise to this challenge is to endow computing systems with increased...
Human-robot teams can incorporate advanced technology such as distributed mobile sensor networks, integrated communications, visualization technology, and other means to acquire and assess information. These factors can greatly affect mission effectiveness, safety, and survivability, by providing critical information and suggesting courses of action. However, information overload can result. Tactical...
Developers spend the majority of their time comprehending code, a process in which identifier names play a key role. Although many identifier naming styles exist, they often lack an empirical basis and it is not quite clear whether short or long identifier names facilitate comprehension. In this paper, we investigate the effect of different identifier naming styles (letters, abbreviations, words)...
Software development, like any prolonged and intellectually demanding activity, can negatively affect the motivation of developers. This is especially true in specific areas of software engineering, such as requirements engineering, test-driven development, bug reporting and fixing, where the creative aspects of programming fall short. The developers' engagement might progressively degrade, potentially...
Screen-based Augmented Reality (AR) systems can be built as a window into the real world as often done in mobile AR applications or using the Magic Mirror metaphor, where users can see themselves with augmented graphics on a large display. The term Magic Mirror implies that the display shows the users enantiomorph, i.e. the mirror image, such that the system mimics a real-world physical mirror. However,...
The emotional response a person has to a living space is predominantly affected by light, color and texture as space-making elements. In order to verify whether this phenomenon could be replicated in a simulated environment, we conducted a user study in a six-sided projected immersive display that utilized equivalent design attributes of brightness, color and texture in order to assess to which extent...
With the immense growth of online social applications, trust plays a more and more important role in connecting users to each other, sharing their personal information and attracting him to receive recommendations. Therefore, how to obtain trust relationships through mining online social networks became a critical issue. To calculate the level of trust between two users, many computational trust models...
People spend a lot of time at their workplace, for example in office environment. After consuming breakfast or lunch during the recess periods, one may feel lazy both physically and mentally. Thus, gaining extra calories may lower the working progress. To motivate individuals for healthier behavior, we designed, executed and tested an application for improving physical activity behavior at workplace...
This study was conducted to examine the effects of Problem Based Learning (PBL) on students' intrinsic motivation compared with that of a conventional approach, in a procedural-based and number-oriented subject. A quasi-experimental study was conducted for five weeks on 81 first-semester Diploma students, who were attending the subject of Fundamental Accounting (DPA1013). An experimental, pre-test...
Imitation is a social learning method in which an individual observes and mimics another's actions. To implement imitation on robots, a number of questions should be answered, including what information should be copied during imitation, how to choose the behaviors to be copied and how to translate the observed behaviors. In this research, we aim to answer the first two questions in an experiment...
Social loafing and free riding are common phenomena that may hinder crowdsourcing. The purpose of this work is to identify the minimum conditions that can promote cooperation and group problem solving avoiding free riding and social loafing. We assume two kinds of scenarios (Recipe A, free riders have access to benefits produced by groups and Recipe B, the benefit produced by groups are shared only...
Mobile applications tend to be used in contexts that change over time. These varying contexts may impact the usability, and potentially the overall user experience, of mobile applications. However, the impact of context from a temporal perspective is not fully considered within usability evaluations. Consequently, this work focuses on a conceptual method that attempts to address this limitation. The...
Construction workers' Workplace Deviant Behavior(WDB) has significant impact on project success. However, existing researches on its occurrence mechanism are mainly focused on personal and organizational factors. Psychological ownership, which has been proved to be a critical variable affecting behavior decision making, has not been considered in the occurrence of construction workers' WDB. This paper...
Product configurators have been widely accepted as important toolkits to bridge customer needs and company offerings in the product customization context. In this scenario, the solution space is predetermined and customers specify each of the product's desired attribute options. Motivated by findings in the areas of consumer behavior and psychology, in this study, we examine how reference or default...
The lack of strong reading comprehension skills affects a student's success in school. This paper aims to examine how fluent and non-fluent readers process text and images by utilizing eye movement methodology. Three types of diagnostic instruments were used to collect data (text-only, text and image and image-only). The experiments also involved personal observation, interviews and Q&A sessions...
An effective change in Human Computer Interaction requires to account of how communication practices are transformed in different contexts, how users sense the interaction with a machine, and an efficient machine sensitivity in interpreting users' communicative signals, and activities. To this aims, the present paper investigates on whether and how positive and negative visual scenes may alter listeners'...
