In this paper we explore different techniques that allow the user to direct interactive evolutionary search. Broadening interaction beyond simple evaluation increases the amount of feedback and bias a user can apply to the search. Increased feedback will have the effect of directing the algorithm to more fruitful areas of the search space. This paper examines whether additional feedback from th...

This paper presents a co-time co-frequency full-duplex (CCFD) massive multiple-input multiple-output (MIMO) system to meet high spectrum efficiency requirements for beyond the fifth-generation (5G) and forthcoming sixth-generation (6G) networks. To achieve equilibrium of energy consumption, resource utilization, overall transmission capacity, an energy-efficient management strategy concerning p...

Our analysis follows a user-centered design (UCD) approach, which prioritizes the users’ needs and work practices in the system design process [3]. We collected data through standard UCD techniques [1,3]: epidemiologist consultations and interviews, observation of the epidemiologists as they interacted with the systems, and iterative user interface prototyping sessions. For the work presented h...

Research into context-aware computing has not sufficiently addressed human and social aspects of design. Existing design frameworks are predominantly software orientated, make little use of cross-disciplinary work, and do not provide an easily transferable structure for cross-application of design principles. To address these problems, this paper proposes a multidisciplinary and user-centred de...

This article reviews the literature on the role that children can play in the design of information technology applications intended for young users themselves. It discusses several relevant design theories—user-centered design, contextual design (CD) or inquiry, participatory design (PD), cooperative inquiry, informant design, and learner-centered design—looks at usability issues in relation t...

Minimizing user cognitive load is suggested as an integral part of human-centered design, where a more intuitive, easy to learn and adaptive interface is desired. In this context, it is difficult to develop optimal strategies to improve the design without first knowing how user cognitive load fluctuates during interaction. In this study, we investigate how cognitive load measurement is affected...

This qualitative inquiry project investigates the political and policy discourses related to education reform in Taiwan. Specifically, it examines the science education reform policies and policy leaders’ vision for the reform. This work also reveals the unique challenges involved in implementing contemporary science education approaches in a Confucian learning culture. Data sources included re...

Increasing evidence has shown that theory-based health behavior change interventions are more effective than non-theory-based ones. However, only a few segments of relevant studies were theory-based, especially the studies conducted by non-psychology researchers. On the other hand, many mobile health interventions, even those based on the behavioral theories, may still fail in the absence of a ...

This study explores a user-centered approach to the comparative evaluation of the Web search tool ProThes against popular all-purpose search engines Yandex and Google. An original research design was developed. Data were collected from 12 volunteers who performed 48 search tasks in total. Main outcomes include: (1) search strategy supported through ProThes can be quite effective for focused Web...

The main current evolutions in industrial design research are the following : 1 The computerization of the early design phases 2 Consumer and user centered design with in particular emotional design 3 The concurrent engineering, with collaborative work supporting tools Our goal is to modelize the preliminary phases of traditional industrial design process, in order to build new computer aided d...
