Interface Usability

While interactive systems have the potential to increase human work performance, those systems are predisposed to usability problems. Different factors might contribute to these problems during the interaction process and as result, the decision-making process might be compromised. This work uses decision support system methods and tools to assist in the analysis of the usability of a university library website, measuring the constructs of effectiveness, efficiency, and learnability. The pilot study involved thirty-five subjects, and after collecting data, a multidimensional view of the data is created and discussed. Later, a What-if analysis is used to investigate the impact of different scenarios on system-use. The work has the potential to assist designers and system administrators at improving their systems.

Using of automated information systems in the field of geolocation data processing increases the control and management efficiency of freight and passenger traffic. The article presents the results of design and software implementation of the automated information system that allows monitoring of GPS tracking data in real time, build routes and set control points for it, generate system messages about the status of vehicles on the route and generate reporting information on the base of user requests. The design of the system architecture and interface was carried out on the basis of developed object and functional data domain models, which take into account its structural and functional features. The microservice approach principles were applied during the developing of the system architecture. The system software is a set of independent services that work in their own process, implement a certain business logic algorithm and communicate with other services through the HTTP protocol. The set of the system software services consists of: a service for working with GPS data, a service for implementing geolocation data processing functions, and a web application service. The main algorithms of the developed system services and their functional features are described in the work. Article’s figures graphically describe developed system site map and system typical Web forms. This data displays the composition of web pages, paths between them and shows the user interface. The design of the user interface was carried out taking into account quality requirements of user graphical web interfaces.

The chapter is organized into five sections. The first section concerns related works. The SSW methodology section presents the design approach, introducing some considerations about the phenomena affecting the HCI process. The third section deals with the system architecture. The fourth section illustrates the annotation primitive operator. The fifth section describes the experiences gained on the field by illustrating several case studies: different scenarios are introduced in which experts have to afford complex problems (e.g. diagnoses, territorial portal organization, tourist guides organization, yard management) in a collaborative asynchronous way and using different devices (e.g. desktop PC, PDAs) to access their SSW from everywhere and in different working contexts. The implemented multimodal interactive environment permits experts to face the problems related to their activity, to update and manage a shared knowledge base and to adapt and evolve their virtual work environment by adding tools becoming unwitting programmer.
