During the process of aircraft design, situation awareness （SA） is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique （SAGAT）. Through the experiment, the SA degrees and heart rate （HR） data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.展开更多

Current attempts to transpose the problem related to linearity of narrative and temporal flows and audiovisual content obstruction by the interactive layer, although pointing out design perspectives--in addition to the structural and visual web patterns--are still insufficient as regards the design of interfaces connected and converged for t-commerce applications. This article considers that these problems arise from the structural basis that support television scripts and streamings. In this sense, this article proposes the hybridization between the linear model, inherited from analogue condition, and nonlinear model, intrinsic to digital media, as a methodological strategy aiming to strength the creation of interactive audiovisual content connected and convergent for this context.展开更多

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

文摘Aircraft cockpit display interface （CDI） is one of the most important human-machine interfaces for information perceiving. During the process of aircraft design, situation awareness （SA） is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique （SAGAT）. Through the experiment, the SA degrees and heart rate （HR） data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.

文摘Interactive digital television is at early stage as regards the interface design, especially in business transactions （t-commerce）. Current attempts to transpose the problem related to linearity of narrative and temporal flows and audiovisual content obstruction by the interactive layer, although pointing out design perspectives--in addition to the structural and visual web patterns--are still insufficient as regards the design of interfaces connected and converged for t-commerce applications. This article considers that these problems arise from the structural basis that support television scripts and streamings. In this sense, this article proposes the hybridization between the linear model, inherited from analogue condition, and nonlinear model, intrinsic to digital media, as a methodological strategy aiming to strength the creation of interactive audiovisual content connected and convergent for this context.
文摘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.

文摘Mixed reality technology has been increasingly used for navigation.While most MR-based navigation systems are currently based on hand-held devices,for example,smartphones,headmounted MR devices have become more and more popular in navigation.Much research has been conducted to investigate the navigation experience in MR.However,it is still unclear how ordinary users react to the first-person view and FOV(field of view)-limited navigation experience,especially in terms of spatial learning.In our study,we investigate how visualization in MR navigation affects spatial learning.More specifically,we test two related hypotheses:incorrect virtual information can lead users into incorrect spatial learning,and the visualization style of direction can influence users’spatial learning and experience.We designed a user interface in Microsoft HoloLens 2 and conducted a user study with 40 participants.The user study consists of a walking session in which users wear Microsoft HoloLens 2 to navigate to an unknown destination,pre-and post-walking questionnaires,sketch map drawing,and a semi-structured interview about the user interface design.The results provide preliminary confirmation that users’spatial learning can be misled by incorrect information,even in a small study area,but this misleading effect can be compensated by considerate visualization,for example,including lines instead of using only arrows as direction indicators.Arrows with or without lines as two visualization alternatives also influenced the user’s spatial learning and evaluation of the designed elements.Besides,the study shows that users’preferences for navigation interfaces are diverse,and an adaptable interface should be provided.The results contribute to the design of head-mounted MR-based navigation interfaces and the application of MR in navigation in general.
文摘With the rise of metaverse-related technologies and industries,user interface design(UID)has become increasingly important in enhancing user experience and engagement.This study focuses on the metaverse platform ZEPETO World,using the Technology Acceptance Model(TAM)as the theoretical framework to investigate the effects of UID elements on users’perceived ease of use(PEOU),perceived usefulness(PU),and behavioral intention(BI)through empirical analysis.A total of 204 valid questionnaires were collected,and multiple regression analysis was conducted to test the theoretical model.The results indicate that typography and responsiveness are the key factors significantly affecting the perceived variables,followed by color and layout.As an essential component of UID elements,aesthetics has no significant direct impact in this technical environment.Additionally,perceived ease of use has a stronger influence on user behavioral intention than perceived usefulness.This study extends the applicability of the TAM model in the metaverse virtual environment and provides both theoretical and practical guidance for the optimization of user interfaces on metaverse platforms.

文摘Objective Based on the development background of digital medical technology,this study aimed to establish design guidelines and references in relevant fields to better serve clinical medical treatment using intelligent technology to enhance the usability of the interaction interface of robotic surgical systems and reduce potential human-factor risks during digital surgery.Methods Considering the robotic liver cancer ablation surgery system as the research object,subjective and objective evaluation indicators were established from 3 dimensions of effectiveness,efficiency,and satisfaction based on the usability theory.Using the hierarchical task analysis method,usability experiments were conducted to collect relevant data.Feedback on issues during the experimental process was obtained through observation and interviews.Failure mode and effect analysis and fault tree analysis were used to assess risk levels and formulate design strategies.Results The interface design of the liver cancer ablation surgery robot was iteratively optimized.The results showed that the interface after iteration improved in skilled operation time,subjective evaluation scores,risk priority number value,and risk level.The rationality of the scheme was verified,and interface design paradigm was constructed based on intelligent technology.Conclusion After improving the design,the interface effectively reduced the frequency of problems and average skilled operation time,thereby,improving the subjective satisfaction score of users.
文摘Under the tide of information,UI design has become the core lever for measuring the quality of digital product experience.As various applications permeate daily life,the quality of interfaces has been in-creasingly magnified.Researchers at home and abroad have devoted their efforts to this,distilling multiple sets of experience paradigms and operational guidelines.Regrettably,the mainstream thinking is still trapped in a two-dimensionalflat framework.When interaction technologies are advancing rapidly and functional in-formationflows are surging in a multi-dimensional and three-dimensional manner,the old logic can no longer fulfill the demand for a user-centered quality experience.First,an emotional indicator framework is established through human-computer engineering.In the weight setting part,the grey correlation is incorporated into the group analytic hierarchy process,and the modified analytic hierarchy process(AHP)is used to calculate the comprehensive weights,thereby weakening the subjectiveflaws of the traditional AHP.Then,in response to the ambiguity of the evaluation,the intuitionistic fuzzy set is integrated with the TOPSIS(technique for order preference by similarity to an ideal solution)ideal similarity ranking method to construct a new comprehensive evaluation model.This study verifies the applicability of human factors engineering in the emotional design of digital interfaces,providing a quantitative path and practical guidelines for the paradigm shift from“usability”to“empathy”.
