This study aims to validate the Object-Oriented User Interface Customization(OOUIC)framework by employing Use Case Analysis(UCA)to facilitate the development of adaptive User Interfaces(UIs).The OOUIC framework advocates for User-Centered Design(UCD)methodologies,including UCA,to systematically identify intricate user requirements and construct adaptive UIs tailored to diverse user needs.To operationalize this approach,thirty users of Product Lifecycle Management(PLM)systems were interviewed across six distinct use cases.Interview transcripts were subjected to deductive content analysis to classify UI objects systematically.Subsequently,adaptive UIs were developed for each use case,and their complexity was quantitatively compared against the original system UIs.The results demonstrated a significant reduction in complexity across all adaptive UIs(Mean Difference,MD=0.11,t(5)=8.26,p<0.001),confirming their superior efficiency.The findings validate the OOUIC framework,demonstrating that UCD effectively captures complex requirements for adaptive UI development,while adaptive UIs mitigate interface complexity through object reduction and optimized layout design.Furthermore,UCA and deductive content analysis serve as robust methodologies for object categorization in adaptive UI design.Beyond eliminating redundant elements and prioritizing object grouping,designers can further reduce complexity by adjusting object dimensions and window sizing.This study underscores the efficacy of UCA in developing adaptive UIs and streamlining complex interfaces.Ultimately,UCD proves instrumental in gathering intricate requirements,while adaptive UIs enhance usability by minimizing object clutter and refining spatial organization. 展开更多

In this review,five graphical user interfaces(GUIs)used in radiation therapy practices and researches are introduced.They are:(1)the treatment time calculator,superficialx-ray treatment time calculator(SUPCALC)used in the superficial X-ray radiation therapy;(2)the monitor unit calculator,electron monitor unit calculator(EMUC)used in the electron radiation therapy;(3)the multileaf collimator machine file creator,sliding window intensity modulated radiotherapy(SWIMRT)used in generating fluence map for research and quality assurance in intensity modulated radiation therapy;(4)the treatment planning system,DOSCTP used in the calculation of 3D dose distribution using Monte Carlo simulation;and(5)the monitor unit calculator,photon beam monitor unit calculator(PMUC)used in photon beam radiation therapy.One common issue of these GUIs is that all user-friendly interfaces are linked to complex formulas and algorithms based on various theories,which do not have to be understood and noted by the user.In that case,user only needs to input the required information with help from graphical elements in order to produce desired results.SUPCALC is a superficial radiation treatment time calculator using the GUI technique to provide a convenient way for radiation therapist to calculate the treatment time,and keep a record for the skin cancer patient.EMUC is an electron monitor unit calculator for electron radiation therapy.Instead of doing hand calculation according to pre-determined dosimetric tables,clinical user needs only to input the required drawing of electron field in computer graphical file format,prescription dose,and beam parameters to EMUC to calculate the required monitor unit for the electron beam treatment.EMUC is based on a semi-experimental theory of sector-integration algorithm.SWIMRT is a multileaf collimator machine file creator to generate a fluence map produced by a medical linear accelerator.This machine file controls the multileaf collimator to deliver intensity modulated beams for a specific fluence map used in quality assurance or research.DOSCTP is a treatment planning system using the computed tomography images.Radiation beams(photon or electron)with different energies and field sizes produced by a linear accelerator can be placed in different positions to irradiate the tumour in the patient.DOSCTP is linked to a Monte Carlo simulation engine using the EGSnrc-based code,so that 3D dose distribution canbe determined accurately for radiation therapy.Moreover,DOSCTP can be used for treatment planning of patient or small animal.PMUC is a GUI for calculation of the monitor unit based on the prescription dose of patient in photon beam radiation therapy.The calculation is based on dose corrections in changes of photon beam energy,treatment depth,field size,jaw position,beam axis,treatment distance and beam modifiers.All GUIs mentioned in this review were written either by the Microsoft Visual Basic.net or a MATLAB GUI development tool called GUIDE.In addition,all GUIs were verified and tested using measurements to ensure their accuracies were up to clinical acceptable levels for implementations. 展开更多

This paper presents a two-agent framework to build a natural langua g e query interface for IC information system, focusing more on scope queries in a single English sentence. The first agent, parsing agent, syntactically p rocesses and semantically interprets natural language sentence to construct a fu zzy structured query language (SQL) statement. The second agent, defuzzif ying agent, defuzzifies the imprecise part of the fuzzy SQL statement into its e quivalent executable precise SQL statement based on fuzzy rules. The first agent can also actively ask the user some necessary questions when it manages to disa mbiguate the vague retrieval requirements. The adaptive defuzzification approach employed in the defuzzifying agent is discussed in detail. A prototype interface has been implemented to demonstrate the effectiveness. 展开更多

Radiation-induced acoustic computed tomography(RACT)is an evolving biomedical imaging modality that aims to reconstruct the radiation energy deposition in tissues.Traditional backprojection(BP)reconstructions carry noisy and limited-view artifacts.Model-based algorithms have been demonstrated to overcome the drawbacks of BPs.However,model-based algorithms are relatively more complex to develop and computationally demanding.Furthermore,while a plethora of novel algorithms has been developed over the past decade,most of these algorithms are either not accessible,readily available,or hard to implement for researchers who are not well versed in programming.We developed a user-friendly MATLAB-based graphical user interface(GUI;RACT2D)that facilitates back-projection and model-based image reconstructions for twodimensional RACT problems.We included numerical and experimental X-ray-induced acoustic datasets to demonstrate the capabilities of the GUI.The developed algorithms support parallel computing for evaluating reconstructions using the cores of the computer,thus further accelerating the reconstruction speed.We also share the MATLAB-based codes for evaluating RACT reconstructions,which users with MATLAB programming expertise can further modify to suit their needs.The shared GUI and codes can be of interest to researchers across the globe and assist them in e±cient evaluation of improved RACT reconstructions. 展开更多

To work efficiently with DSS, most users need assistance in representation conversion, i. e., translating the specific outcome from the DSS into the universal language of visual. In generally, it is much easier to understand the results from the DSS if they are translated into charts, maps, and other scientific displays, because visualization exploits human natural ability to recognize and understand visual pattern. In this paper we discuss the concept of visualization for DSS. AniGraftool, a software system, is introduced as an example of Visualized User Interface for DSS. 展开更多

To meet the challenges of ubiquitous computing, ambient technologies and an increasingly older population, researchers have been trying to break away from traditional modes of interaction. A history of studies over the past 30 years reported in this paper suggests that Gesture Controlled User Interfaces (GCUI) now provide realistic and affordable opportunities, which may be appropriate for older and disabled people. We have developed a GCUI prototype application, called Open Gesture, to help users carry out everyday activities such as making phone calls, controlling their television and performing mathematical calculations. Open Gesture uses simple hand gestures to perform a diverse range of tasks via a television interface. This paper describes Open Gesture and reports its usability evaluation. We conclude that this inclusive technology offers some potential to improve the independence and quality of life of older and disabled users along with general users, although there remain significant challenges to be overcome. 展开更多

Context awareness is increasingly gaining applicability in interactive ubiquitous mobile computing systems. Each context-aware application has its own set of behaviors to react to context modifications. Hence, every software engineer needs to clearly understand the goal of the development and to categorize the context in the application. We incorporate context-based modifications into the appearance or the behavior of the interface, either at the design time or at the run time. In this paper, we present application behavior adaption to the context modification via a context-based user interface in a mobile application. We are interested in a context-based user interface in a mobile device that is automatically adapted based on the context information. We use the adaption tree, named in our methodology, to represent the adaption of mobile device user interface to various context information. The context includes the user’s domain information and dynamic environment changes. Each path in the adaption tree, from the root to the leaf, presents an adaption rule. An e-commerce application is chosen to illustrate our approach. This mobile application was developed based on the adaption tree in the Android platform. The automatic adaption to the context information has enhanced human-computer interactions. 展开更多

In the last two decades, tangible user interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. TUIs show a potential to enhance the way in which people interact with digital information. First, this paper exam- ines the existing body of work on tangible user interfaces and discusses their application domains, especially information visualiza- tion. Then it provides a definition of intuitive use and reviews formerly separated ideas on physicality. As interaction has an impact on the overall product experience, we also discuss whether intuitive use influences the users' aesthetic judgements of such products. 展开更多

This paper describes the design and evaluation of a user interface for a remotely supervised autonomous agricultural sprayer. The interface was designed to help the remote supervisor to instruct the autonomous sprayer to commence operation, monitor the status of the sprayer and its operation in the field, and intervene when needed (i.e., to stop or shut down). Design principles and guidelines were carefully selected to help develop a human-centered automation interface. Evaluation of the interface using a combination of heuristic, cognitive walkthrough, and user testing techniques revealed several strengths of the design as well as areas that needed further improvement. Overall, this paper provides guidelines that will assist other researchers to develop an ergonomic user interface for a fully autonomous agricultural machine. 展开更多

As agricultural machines become more complex, it is increasingly critical that special attention be directed to the design of the user interface to ensure that the operator will have an adequate understanding of the status of the machine at all times. A user-centred design focus was employed to develop two conceptual designs (UCD1 & UCD2) for a user interface for an agricultural air seeder. The two concepts were compared against an existing user interface (baseline condition) using the metrics of situation awareness (Situation Awareness Global Assessment Technique), mental workload (Integrated Workload Scale), reaction time, and subjective feedback. There were no statistically significant differences among the three user interfaces based on the metric of situation awareness;however, UCD2 was deemed to be significantly better than either UCD1 or the baseline interface on the basis of mental workload, reaction time and subjective feedback. The research has demonstrated that a user-centred design focus will generate a better user interface for an agricultural machine. 展开更多

Autonomous vehicles (AVs) hold immense promises in revolutionizing transportation, and their potential benefits extend to individuals with impairments, particularly those with vision and hearing impairments. However, the accommodation of these individuals in AVs requires developing advanced user interfaces. This paper describes an explorative study of a multimodal user interface for autonomous vehicles, specifically developed for passengers with sensory (vision and/or hearing) impairments. In a driving simulator, 32 volunteers with simulated sensory impairments, were exposed to multiple drives in an autonomous vehicle while freely interacting with standard and inclusive variants of the infotainment and navigation system interface. The two user interfaces differed in graphical layout and voice messages, which adopted inclusive design principles for the inclusive variant. Questionnaires and structured interviews were conducted to collect participants’ impressions. The data analysis reports positive user experiences, but also identifies technical challenges. Verified guidelines are provided for further development of inclusive user interface solutions. 展开更多

The User Interface Transition Diagram (UITD) is a formal modeling notation that simplifies the specification and design of user-system interactions. It is a valuable communication tool for technical and non-technical stakeholders during the requirements elicitation phase, as it provides a simple yet technically complete notation that is easy to understand. In this paper, we investigated the efficiency of creating UITDs using draw.io, a widely used diagramming software, compared to a dedicated UITD editor. We conducted a study to compare the time required to use each tool to complete the task of creating a medium size UITD, as well as the subjective ease of use and satisfaction of participants with the dedicated Editor. Our results show that the UITD editor is more efficient and preferred by participants, highlighting the importance of using specialized tools for creating formal models such as UITDs. The findings of this study have implications for software developers, designers, and other stakeholders involved in the specification and design of user-system interactions. 展开更多

The problem of privacy in social networks is well documented within literature;users have pri- vacy concerns however, they consistently disclose their sensitive information and leave it open to unintended third parties. While numerous causes of poor behaviour have been suggested by re- search the role of the User Interface (UI) and the system itself is underexplored. The field of Per- suasive Technology would suggest that Social Network Systems persuade users to deviate from their normal or habitual behaviour. This paper makes the case that the UI can be used as the basis for user empowerment by informing them of their privacy at the point of interaction and remind- ing them of their privacy needs. The Theory of Planned Behaviour is introduced as a potential theoretical foundation for exploring the psychology behind privacy behaviour as it describes the salient factors that influence intention and action. Based on these factors of personal attitude, subjective norms and perceived control, a series of UIs are presented and implemented in con- trolled experiments examining their effect on personal information disclosure. This is combined with observations and interviews with the participants. Results from this initial, pilot experiment suggest groups with privacy salient information embedded exhibit less disclosure than the control group. This work reviews this approach as a method for exploring privacy behaviour and propos- es further work required. 展开更多

The development of software as a service represents a great advantage for the users of cloud computing, such as users of small, medium or large organizations. All these users possess different characteristics, which must be taken into account as reference for the interface development of a software product. This paper considers the element of a user experience model, with the purpose of getting to know the different features that must be taken into account during the development of software as a service. This also involves the participation of different types of users of the SaaS layer model together with the users’ interaction skills level. This paper offers a framework of the involvement actors in the design of a software interface as a service, with the objective of identifying their participation outside and within the organization. The purpose is to create an interface centered on the user, involving clients and experts to work collaboratively;and get usable software as a service application. 展开更多

Based on force control, a robotic subsystem has been developed for path automatic generation or path learning. Using a dummy tool and roughly taught guiding points around a part contour, the robot moves in position and force controlled hybrid mode, following the order of the guiding points and with contact force direction and value predefined. During the motion, robot actual position is recorded by the robot controller. After the motion, the recorded position data is used to generate a robot path program automatically. Robot lead-through may be used in the guiding point teaching. Furthermore, a GUI (graphical user interface) is developed on the teach pedant to guide through the guiding point creation and teaching, path learning, program verification and execution. The development has been incorporated into a robotic machining product option. Combination of the robot path learning function and GUI enhances the interaction between the robot and operator and drastically increases the level of robotic ease-of-use. 展开更多
