The purpose of this paper is to evaluate six different graphical user interfaces (GUIs) for facilities operations using human–machine interaction (HMI) theories.

The authors used a combined multi-functional method that includes a review of the theories behind HMI for GUIs as its first approach. Consequently, heuristic evaluations were conducted to identify usability problems in a professional context. Ultimately, thematic interviews were conducted with property managers and service staff to determine special needs for the interaction of humans and the built environment.

The heuristic evaluation revealed that not all the studied applications were complete when the study was done. The significant non-motivational factor was slowness, and a lighter application means the GUI is more comfortable and faster to use. The evaluators recommended not using actions that deviate from regular practice. Proper implementation of the GUI would make it easier and quicker to work on property maintenance and management. The thematic interviews concluded that the GUIs form an excellent solution that enables communication between the occupant, owner and service provider. Indoor conditions monitoring was seen as the most compelling use case for GUIs. Two-dimensional (2D) layouts are more demonstrative and faster than three-dimensional (3D) layouts for monitoring purposes.

The study provides an objective view of the strengths and weaknesses of specific types of GUI. So, it can help to select a suitable GUI for a particular environment. The 3D view is not seen as necessary for monitoring indoor conditions room by room or sending a service request. Many occupants’ services can be implemented without any particular layout. On the other hand, some advanced services were desired for the occupants, such as monitoring occupancy, making space reservations and people tracking. These aspects require a 2D layout at least. The building information model is seen as useful, especially when monitoring complex technical systems.

Earlier investigations have primarily concentrated on investigating human–computer interaction. The authors’ studied human–building interaction instead. The notable difference to previous efforts is that the authors considered the GUI as a medium with which to communicate with the built environment, and looked at its benefits for top-level processes, not for the user interface itself.

The World Wide Web has undergone a rapid transition from the originally static hypertext to an ubiquitous hypermedia system. Today, the Web is not only used as a basis for distributed applications (Web applications), moreover it serves as a generic architecture for autonomous applications and services. Many research work has been done regarding the modeling and engineering process of Web applications and various platforms, frameworks and development kits exist for the efficient implementation of such systems. Concerning the modeling process, many of the published concepts try to merge traditional hypermedia modeling with techniques from the software engineering domain. Unfortunately, those concepts which capture all facets of the Web’s architecture become rather bulky and are eventually not applicable for a model‐driven Web application development. Moreover, there is a need for frameworks which address both, the modeling process and the implementation task and allow a model driven, semi‐automatic engineering process using CASE tools. This paper outlines the DaVinci Web Engineering Framework which supports the modeling as well as the semi‐automated implementation of Web applications. The DaVinci Architectural Layer specifies a persistent, hierarchical GUI model and a generic interaction scheme. This allows the elimination of the hypermedia paradigm, which turned out to be rather practical when building Web applications.

Looks at the problems that visually disabled people are experiencing with the increasing use of computer software with graphical user interfaces [GUIs] and the move away from text based interfaces. The GUIB project, funded by the European Commission, has been looking at ways of solving this problem and has developed a terminal which integrates vertical and horizontal braille displays, a multi lingual speech synthesizer, other acoustic signals and a pressure sensitive touch pad. The guide display makes it possible for a blind person to look at the screen in a spatial way. The project has also identified ten principles to assist in the training of blind people in the use of GUIs. Concludes that in the future it will be necessary to anticipate new technological advances and ensure that they are developed with the needs of disabled people in mind.

Motif User Interface Application (MUIApp) is an object‐oriented graphical user‐interface application framework. It simplifies the task of writing, modifying, and debugging window‐based applications by application of object‐oriented programming to the construction and manipulation of graphical user interface (GUI) components using a well‐established window system. The key means adopted in the design include: encapsulation of tedious X‐window programming details, construction of high‐level GUI components using Motif and Xt widgets as the primary building blocks, and definition of collaboration mechanisms between GUI components. Reports that the abstractions and mechanisms provided by MUIApp facilitate the development of graphical user interfaces for applications. Simplicity, extensibility and reusability are the key concerns in the design. MUIApp is written in C++ and runs mainly on top of Motif.

The purpose of this paper is to analyse the operation pattern of the virtual university‐industry‐government (GUI) platform from the perspective of knowledge.

Following a theoretical framework, the case of the China Zhejiang Online Technology Market (ZJOTM) is analyzed, which has been viewed as a model of the national virtual GUI platform. The operation pattern and effect of ZJOTM are discussed. The material and data are collected mainly from ZJOTM web site.

According to the types of knowledge interaction between university and industry, this paper recognizes the context needed for knowledge interaction between industry and university as “virtual ba”, “physical ba” and “practice ba”. The virtual GUI platform just provides a virtual ba for knowledge interaction between industry and university. However, only “virtual ba” is not sufficient, “physical ba” and “practice ba” are also needed. Therefore, the operation of virtual GUI should utilize the complementary action of physical ba and practice ba. Moreover, it is better to deploy the ba flexibly according to the knowledge and sector characteristic.

The paper specifies the innovation knowledge rich in industry and university and the knowledge interaction context needed, that provides a favourable framework to study the operation pattern of the virtual GUI platform. The findings also have important implications for government policy makers, university and industry practice for designing and implementing knowledge‐base innovation strategies.

Following a general trend in software development, CDROM applications are increasingly implementing Graphical User Interfaces (GUIs). The general assumption is that GUIs offer advantages in terms of ease of learning and use, especially for non‐expert users. Moreover, the adoption of GUIs for CDROMs has been suggested as a means of providing a de facto standard interface. This study assesses the appropriateness of GUIs, more specifically Windows‐based interfaces for CDROM. An evaluation model was devised to carry out an expert evaluation of the interfaces of seven CDROM products. The model identified two levels of interaction, the dialogue level and task level, and focused on general interface features, search and retrieval tasks, and output and processing options as well as the help facilities. The results are discussed in the light of HCI Usability Criteria and design guidelines (including general interface design guidelines, specific Windows design guidelines and The CDROM Consistent Interface Guidelines) to assess to what extent the applications comply and appropriate recommendations are made.

Introduction One of the most important developments in information technology over the past ten years or so, quite apart from the massive improvements in hardware technology, has been the graphical user interface (GUI). For most people it has been a positive innovation, but for some, particularly those who are blind or visually impaired, it has been a rising threat as a barrier to the technology. Now that such interfaces have matured and become the norm, adaptations have been developed and perhaps that threat is not as bad as it was once feared to be. This article describes the development of the GUI, explains why it is so significant, and discusses whether it has been “tamed” with respect to use by people with visual disabilities.

There has been a burgeoning interest in exploring the impact of uncertainty factors on share returns. However, studies on the influence of global financial uncertainties on emerging market sectoral indices are scarce. Thus, there is a need to have a thorough investigation of the connection between global financial uncertainties and emerging market sectoral indices. To fill this gap, using the theoretical framework of international portfolio diversification (IPD) and utilizing data from 2008 to 2021, this study examines the spillover connection between global uncertainty indices (GUIs) and leading sectoral indices of 28 emerging markets.

The authors employ the quantile spillover-based connectedness approach and minimum connectedness portfolio approach to explore the dynamic connectedness among sectoral indices and global uncertainty indices (GUIs) as well as portfolio implication.

The study found high connectedness among all indices, especially at higher and lower quantiles. Among GUIs, the authors find that stock market volatility (VIX) and oil volatility index (OVX) are strongly interconnected with all leading emerging markets' sectoral indices. Among sectoral indices, the linkage between the financial (F-Index), information technology (IT-Index), and consumer discretionary (CD-Index) sectors shows moderate interconnectedness. In contrast, the communication services (CS-Index) sector has low interconnectedness with the system. In terms of spillover effects, the authors find EVZ, OVX, and the IT sectors to be net recipients for the entire period. The authors also explored portfolio diversification benefits by employing a minimum connectedness portfolio approach. The cumulative returns' findings show a slight decline in the portfolio's value after 2010; during 2012, the pattern remained stable; from 2014 to 2020, the portfolio performed negatively, that is, underperformance due to different events in that period, including COVID-19. The Consumer Discretionary sector is found to be significant because of having the largest weight, 51%, in the portfolio during the study period.

The study suggests that investors should invest in the communication services sector as it is the least connected. However, the connectedness increases during COVID-19, which implies that it may be difficult for investors to benefit from IPD in a crisis period. Hence, to obtain the benefits from IPD, the evidence suggests that investors need to consider Consumer Discretionary sector while considering assets for investment.

The study's uniqueness is that the authors have investigated spillover between GUIs and 28 emerging markets sectoral indices by employing a quantile spillover-based connectedness approach and minimum connectedness portfolio approach with a special focus on portfolio implication.

The purpose of this paper is to address a library service based on semantic web technologies capable of exposing knowledge that is otherwise hidden in a library's subject headings repository.

The proposed service implements a web‐based information seeking process that combines browsing and searching of information assets within a library, based on their corresponding subject headings. The underlying subject headings hierarchy is the Greek translation of a subset of the official Library of Congress subject headings. The information seeking process exposes the expressiveness of an underlying ontology capable of modeling subject headings together with their relations.

In order to assess the effectiveness of the proposed approach in a real‐world scenario, the library service is integrated into a working OPAC located at the Ionian University in Greece. Thus, the library service contributes to the fast retrieval of information. Moreover, during the information seeking process, users underpin their cognitive learning.

The paper introduces a novel service for the library domain capable of being integrated in many library portals. Serving as a semantic web application, the proposed work promotes interactive navigation in ontology structures that could be potentially exploited by ontologies developed in other domains.
