The Neocolonial Structural Model Re-Foundation and The Pragmatic Inference of Organizational Culture in Ngugi Wa Thiongo’s Devil on The Cross (1980)

Through the frame frequency of the imported state and the westernization of the African political order, the social construction of the African bureaucracy appears as a structural device of abstraction, exploitation, and brutality. Then, through the frame of reference with the importation of conceptual juridical coordination and perceptual representative consensus, the African public administration enhances a frameshift transformation and a succession of causality. Therefore, in combinatorial and transactional analysis, the framework of Devil On The Cross progresses in a method of empirical processing decomposition. Within this respect, the elemental and pure imaginary of the African administration proceeds as a functional derivative governmentality and a colonial functional inception power. Subsequently, with its interaction design, processing system, and volume technique, the realm of Devil On The Cross inserts a paradigmatic analysis and a value engineering within which this African administration happens as an characteristic structural formula and an inefficient relational frame theory. Moreover, within the space-time continuum, the configuration management and the linear configuration programming of the African management apparatus, Devil On The Cross becomes a holomorphic function and an analytic continuation that reveal the anachronism nature and the asynchronous system of the African post-colonial administration.

Spreadsheets on Interactive Surfaces: Breaking through the Grid with the Pen

Spreadsheet programs for interactive surfaces have limited manipulations capabilities and are often frustrating to use. One key reason is that the spreadsheet grid creates a layer that intercepts most user input events, making it difficult to reach the cell values that lie underneath. We conduct an analysis of commercial spreadsheet programs and an elicitation study to understand what users can do and what they would like to do with spreadsheets on interactive surfaces. Informed by these, we design interaction techniques that leverage the precision of the pen to mitigate friction between the different layers. These enable more operations by direct manipulation on and through the grid, targeting not only cells and groups of cells, but values and substrings within and across cells as well. We prototype these interaction techniques and conduct a qualitative study with information workers who perform a variety of spreadsheet operations on their own data.

A Framework for Guiding the Design of Interactive Systems for Communication through Activities in Higher Learning Institutions

Human-computer interaction is paramount in the process of designing interactive-computer systems with high capabilities of guaranteeing users’ satisfaction. However, lack of suitable frameworks complicates their effective design. This study investigated suitable frameworks capable of guiding appropriate design of interactive systems for communication through activities (ISCA) in higher learning institutions in Tanzania. These systems are necessary for augmenting communication thereby overcoming persistent challenges related to their reliance on face-to-face, phone-based, and social networking websites communications. This study used a thorough user centred design approach where a framework for human activity design-centred (HADC) was employed. Authors qualitatively analysed data on communication and interaction issues from participants involved. Design science research was then combined with activity theory to develop a four-phased methodology which was used to design an intended human activity interactive communication (HAIC) framework. The findings confirmed that interactions design techniques based on human-activities undertaken are fundamental in designing communication frameworks capable of guiding suitable design of interactive systems in a particular setting. In the context of this study, and with ISCA need, the obtained HAIC framework was found to be appropriate. This study found out that the current user-centred design approach does not explain precisely how designers can employ activity-based interaction design techniques into the design process. Thus, the study contributes to the literature on users’ involvement in interactive systems’ design through the HADC framework provided

Computer Vision Interaction Design in Sustainable Urban Development: A Case Study of Roof Garden Landscape Plants in Marine Cities.

The rapid urbanization and the increasing need for sustainable development have led to the emergence of green roof landscapes in ocean cities. These rooftop gardens provide numerous environmental benefits and contribute to the overall well-being of urban dwellers. However, optimizing the design and interaction experience of green roof landscapes requires the integration of intelligent technologies. This paper explores the application of computer visual design techniques, specifically 3DMAX modeling and virtual reality, in the intelligent interaction design of green roof landscape plants in ocean cities. Designers can use computer visual design (3DMAX) and other technologies to interact intelligently with the roof landscape in order to improve landscape design. Through case studies, this indicated that computer vision is excellent for image processing of rooftop landscapes and also demonstrates a high degree of compatibility between computer vision and green rooftop landscape plant design in marine cities. This paper highlights the significance of intelligent interaction design and computer visual design techniques in optimizing the integration of green roof landscape plants in ocean cities. It emphasizes the potential of 3DMAX modeling and VR technology in creating immersive and engaging experiences for designers, users, and stakeholders alike. The findings contribute to the growing body of knowledge in the field of sustainable urban development and provide insights for designers, policymakers, and researchers seeking to enhance green roof landscapes in ocean cities. The dissertation highlights the potential of using computer vision design techniques to enhance the roof garden landscaping process and advocates for more efficient and effective ways to design, visualize, and improve rooftop gardens by utilizing software equipped with computer vision technology such as 3DMAX, ultimately contributing to the advancement of sustainable urban landscapes.

Unveiling the Dynamics of African Post-Colonial Administration: A Holistic Analysis of Devil on the Cross

Interacting with educational chatbots: A systematic review

Chatbots hold the promise of revolutionizing education by engaging learners, personalizing learning activities, supporting educators, and developing deep insight into learners’ behavior. However, there is a lack of studies that analyze the recent evidence-based chatbot-learner interaction design techniques applied in education. This study presents a systematic review of 36 papers to understand, compare, and reflect on recent attempts to utilize chatbots in education using seven dimensions: educational field, platform, design principles, the role of chatbots, interaction styles, evidence, and limitations. The results show that the chatbots were mainly designed on a web platform to teach computer science, language, general education, and a few other fields such as engineering and mathematics. Further, more than half of the chatbots were used as teaching agents, while more than a third were peer agents. Most of the chatbots used a predetermined conversational path, and more than a quarter utilized a personalized learning approach that catered to students’ learning needs, while other chatbots used experiential and collaborative learning besides other design principles. Moreover, more than a third of the chatbots were evaluated with experiments, and the results primarily point to improved learning and subjective satisfaction. Challenges and limitations include inadequate or insufficient dataset training and a lack of reliance on usability heuristics. Future studies should explore the effect of chatbot personality and localization on subjective satisfaction and learning effectiveness.

The Compositor Tool: Investigating Consumer Experiences in the Circular Economy

Humanity is living through a crisis that sees our way of life exhausting the resources of the earth and ourselves. The fashion sector shows the negative impacts of conspicuous consumption on our socioenvironmental wellbeing. Despite citizens’ growing awareness of their responsibility within consumption cycles, they reveal concerns about their lack of understanding and the support required for them to become agents of responsible consumption. The Circular Economy flourishes as a conceptual approach to help society transition to a more sustainable existence. This paper explores how emerging creative technology and interaction design might support a shift in the role of citizens in the Circular Economy. We performed a design inquiry that investigated the moment of acquisition via configuration of products, storytelling, and multimodal interaction techniques for the creation of experiences that could catalyse citizen-consumers to become custodians of materials. We developed a retail-based concept tool—The Compositor Tool—with which we ran a user study to investigate new experiential ways that consumers can participate in materials’ circularity. The study highlighted how experience design and new interaction techniques can introduce circularity as part of consumer experience by forging deeper connections between people and products/materials and enabling consumers to have more creative and informative material engagement.

Mediating distance: new interfaces and interaction design techniques to follow and take part in remote museum visits

PurposeThis paper presents a study of a system that allows remote and onsite visitors to share a museum visit together in real time. The remote visitors are older adults at a care home and their relatives and/or friends who are at the museum. The museum visits are interactive. Meaningful stories accompany the museum exhibits, and there’s an audio channel between onsite and remote visitors. The aim of the study is to determine whether the remote visitors, i.e. older adults are able to use such technology and to study the mediated sense of spatial presence, social closeness, engagement and enjoyment in the visit. This study discusses the relationship between these aspects and factors leading to a better remote experience for older adults.Design/methodology/approachThis study has 14 onsite and 12 remote older adult participants. Standardized questionnaires measured the mediated sense of spatial presence, the experienced social closeness and the level of participants' engagement and enjoyment in the visit of the older adult participants and traced onsite visitors in their position during the visit. The audio logs were subjected to thematic content analysis.FindingsThe results show that older adults enjoy and engage in remote visits, and that there is a positive correlation between enjoyment, engagement and social closeness. The findings argue that both the audio channel and the interactive story are important for creating an affective virtual experience: the audio channel increases the sense of closeness, whereas the interactive story makes the visit more engaging, providing structure, direction and purpose to the visit.Originality/valueThis work advances the state of art in the domain of technologies for older adults and addresses the needs of this population to stay in contact with both people and places.

Decal-Lenses: Interactive Lenses on Surfaces for Multivariate Visualization.

We present decal-lenses, a new interaction technique that extends the concept of magic lenses to augment and manage multivariate visualizations on arbitrary surfaces. Our object-space lenses follow the surface geometry and allow the user to change the point of view during data exploration while maintaining a spatial reference to positions where one or more lenses were placed. Each lens delimits specific regions of the surface where one or more attributes can be selected or combined. Similar to 2D lenses, the user interacts with our lenses in real-time, switching between different attributes within the lens context. The user can also visualize the surface data representations from the point of view of each lens by using local cameras. To place lenses on surfaces of intricate geometry, such as the human brain, we introduce the concept of support surfaces for designing interaction techniques. Support surfaces provide a way to place and interact with the lenses while avoiding holes and occluded regions during data exploration. We further extend decal-lenses to arbitrary regions using brushing and lassoing operations. We discuss the applicability of our technique and present several examples where our lenses can be useful to create a customized exploration of multivariate data on surfaces.

Informing Work Interaction Design by 3rd Generation Activity Theory

In this paper, we reflect on stakeholder interaction design supported by task behavior specifications and stakeholder benefits when framing design with (i) eliciting task knowledge and understanding work activities and activity systems, (ii) means of interactional representation for design, and (iii) capturing the dynamics of activity systems. Thereby, complimentary inputs to theory development and work interaction design techniques become evident. In particular, eliciting implicit knowledge on human task accomplishment and work processes helps understanding and representing activities as design-relevant behavior entities. Eliciting implicit knowledge influences the representation of work knowledge and the subsequent design process of socio-technical systems. We elaborate on some methodological interventions for creating stakeholder task behavior models, including patterns of information exchange for collaborative task accomplishment.

Developing Predictive Equations to Model the Visual Demand of In-Vehicle Touchscreen HMIs

ABSTRACTTouchscreen human–machine interfaces (HMIs) are commonly employed as the primary control interface and touch-point of vehicles. However, there has been very little theoretical work to model the demand associated with such devices in the automotive domain. Instead, touchscreen HMIs intended for deployment within vehicles tend to undergo time-consuming and expensive empirical testing and user trials, typically requiring fully functioning prototypes, test rigs, and extensive experimental protocols. While such testing is invaluable and must remain within the normal design/development cycle, there are clear benefits, both fiscal and practical, to the theoretical modeling of human performance. We describe the development of a preliminary model of human performance that makes a priori predictions of the visual demand (total glance time, number of glances, and mean glance duration) elicited by in-vehicle touchscreen HMI designs, when used concurrently with driving. The model incorporates information theoretic components based on Hick–Hyman Law decision/search time and Fitts’ Law pointing time and considers anticipation afforded by structuring and repeated exposure to an interface. Encouraging validation results, obtained by applying the model to a real-world prototype touchscreen HMI, suggest that it may provide an effective design and evaluation tool, capable of making valuable predictions regarding the limits of visual demand/performance associated with in-vehicle HMIs, much earlier in the design cycle than traditional design evaluation techniques. Further validation work is required to explore the behavior associated with more complex tasks requiring multiple screen interactions, as well as other HMI design elements and interaction techniques. Results are discussed in the context of facilitating the design of in-vehicle touchscreen HMI to minimize visual demand.

High-Volume Hypothesis Testing

Cohort comparison studies have traditionally been hypothesis driven and conducted in carefully controlled environments (such as clinical trials). Given two groups of event sequence data, researchers test a single hypothesis (e.g., does the group taking Medication A exhibit more deaths than the group taking Medication B?). Recently, however, researchers have been moving toward more exploratory methods of retrospective analysis with existing data. In this article, we begin by showing that the task of cohort comparison is specific enough to support automatic computation against a bounded set of potential questions and objectives, a method that we refer to as High-Volume Hypothesis Testing (HVHT). From this starting point, we demonstrate that the diversity of these objectives, both across and within different domains, as well as the inherent complexities of real-world datasets, still requires human involvement to determine meaningful insights. We explore how visualization and interaction better support the task of exploratory data analysis and the understanding of HVHT results (how significant they are, why they are meaningful, and whether the entire dataset has been exhaustively explored). Through interviews and case studies with domain experts, we iteratively design and implement visualization and interaction techniques in a visual analytics tool, CoCo. As a result of our evaluation, we propose six design guidelines for enabling users to explore large result sets of HVHT systematically and flexibly in order to glean meaningful insights more quickly. Finally, we illustrate the utility of this method with three case studies in the medical domain.

Programing the rewinding of a three-phase induction motor stator using interactive computer-aided design technique

In this paper, a computer program was developed in MATLAB programming language and applied in the refurbishment of defective three-phase squirrel-cage induction motor using the computer-aided design technique/approach. The MATLAB programming language and Computer-Aided Design (CAD) analysis adopted aided the fast computation and convergence of a output result from the developed program that was used in the practical refurbishment of a defective 48-slot 3-phase squirrel-cage induction motor as well as the production of the entire stator winding. The result also revealed the motor as being a 4-pole type which lends itself easily to the lap winding pattern. The winding was practically developed using the program result data, installed, connected and tested. The speed realized from the post-refurbishment workshop test-running using the stroboscopic speed measuring instrument was 1500rpm. This was considered as good performance on no-load condition. The machine was allowed to run for about one hour during the workshop test-running without overheating. The computed output power was 20 kW. The estimated efficiency and power factor by CAD technique were 90 % and 0.9, respectively. These values were considered satisfactory.

Condensed Matter Theory of Dipolar Quantum Gases

Recent experimental breakthroughs in trapping, cooling and controlling ultracold gases of polar molecules, magnetic and Rydberg atoms have paved the way toward the investigation of highly tunable quantum systems, where anisotropic, long-range dipolar interactions play a prominent role at the many-body level. In this article we review recent theoretical studies concerning the physics of such systems. Starting from a general discussion on interaction design techniques and microscopic Hamiltonians, we provide a summary of recent work focused on many-body properties of dipolar systems, including: weakly interacting Bose gases, weakly interacting Fermi gases, multilayer systems, strongly interacting dipolar gases and dipolar gases in 1D and quasi-1D geometries. Within each of these topics, purely dipolar effects and connections with experimental realizations are emphasized.

On designing interactivity awareness for ambient displays

In the not-so-distant world in which ambient displays will likely become prevalent, immediate awareness of their interaction affordances to passerbies will be decisive for their usability. However, how to address awareness at user perception level represents a challenge for which little progress has been made so far in contrast with considerable advances in designing interaction techniques for such displays. Even though many interactive ambient displays exist with properly designed interfaces, people may not always be aware of their interactivity. This work addresses the problem of interactivity awareness by focusing on two important questions: How can people tell whether a public display is interactive or not? and, assuming interactivity, How can people tell what the interface is? A study was conducted in order to investigate factors potentially related to perceived interactivity. Results show that people's evaluations are correct in most cases but they also tend to form incorrect perceptions in many other situations. We found that location, installation, reachability, and displayed content are factors that can influence people's perceptions. Our findings are complemented with a discussion of techniques that can be used in the practice of designing for interactivity awareness.

Projector phone use: practices and social implications

Phones with integrated pico projectors are starting to be marketed as devices for business presentations and media viewing, and researchers are beginning to design projection-specific applications and interaction techniques to explore a broader array of possible uses. To begin to document how people use projector phones outside the laboratory, we present the results of a 4-week exploratory field study of naturalistic use of commodity projector phones. In our analysis, we consider how context, such as group size, relationships, and locale, influences projector phone use. A key observation is that users can readily exploit the new facilities of these devices to author interesting effects by employing representational techniques such as superimposition, scaling, translation, and motion. Thus, even the "basic" projector phone platform affords novel interaction modalities. Finally, we discuss the social implications of projector phone use for privacy and control, extrapolating from our observations to envision a future in which these devices are ubiquitous. With ubiquity, projector phone use may become problematic in public settings, motivating new rules of etiquette and perhaps laws, yet it may also engender new forms of creative expression.

The Impact of Data Quality Tags on Decision-Making Outcomes and Process

It has been proposed that metadata describing data quality (DQ), termed DQ tags, be made available in situations where decision makers are unfamiliar with the data context, for example, in data warehouses. However, there have been conflicting reports as to the impact of such DQ tags on decision-making outcomes. Early studies did not explicitly consider the usability and semantics of the DQ tag designs used experimentally or the impact of such tags on decision process, except in suggestions for future research. This study addresses these issues, focusing on the design of usable DQ tags whose semantics are explicitly specified and exploring the impact of such DQ tags on decision outcomes and process. We use the information quality framework InfoQual, the interaction design technique of contextual inquiry, and cognitive process tracing to address DQ tag semantics, usability, and impact on decision process, respectively. In distinct contrast to earlier laboratory experiments, there was no evidence that the preferred decision choice changed with DQ tags, but decision time was significantly increased and there were indications of reduced consensus. These results can be explained by understanding the impact of DQ tags on decision process using concurrent protocol analysis, which involves participants verbalizing thoughts while making a decision. The protocol analysis study shows that DQ tags are associated with increased cognitive processing in the earlier phases of decision making, which delays generation of decision alternatives.

Ajax 기반의 웹2.0 서비스를 위한 인터랙션 디자인 가이드라인에 대한 연구

After the beginning of Web2.0 era, newly developed interaction design patterns based on Ajax(Asynchronous JavaScript and XML) have been tried in various Web2.0 services. These new interaction design patterns enable web service to provide rich experience for users. However, it is very hard to find organized task based guideline about Web2.0 interaction design even though there are a lot of complicated interaction design techniques and patterns. It is essential to have Web2.0 interaction guide based on Ajax because it can guide designers to use appropriate interaction design patterns and to keep usability for ordinary users. Therefore, this research aims to establish task based interaction design guideline for Web2.0 service based on Ajax. The reason why this research focused on Ajax is that Ajax is most widely used language for Web2.0 service. First, primary five interaction design patterns were defined through analysis of various interaction design patterns from Web2.0 services. Second, detail interaction design tasks from five major patterns were analyzed based on the study of major Web2.0 services such as Gmail, Twitter, YouTube and Google maps. Third, general design guidelines such as heuristic guidelines for web service are studied through literature review. After all, this study proposed task based interaction design guide for Web2.0 service with Ajax. With this guide, designers and developers can choose appropriate Web2.0 interaction patterns and apply to their service and provide service to users with enhanced usability and satisfaction.
