This paper discusses the development of a user-centered control stand for the Federal Railroad Administration’s (FRA) Next Generation Locomotive Cab (NGLC) demonstration program. A “modified” Association of American Railroads (AAR) 105 side-mounted control stand was used as a starting point to facilitate bidirectional locomotive operation. Researchers applied a variety of qualitative human factor methods, including literature review, naturalistic observation, computer modeling, and heuristic evaluation, to design the improved control stand. The final design included a decluttered side control stand, a short desktop with three-panel front touchscreen displays that can accommodate and integrate current and future locomotive train technologies, and an overhead ceiling panel that replaces, in part, controls and displays traditionally located behind the engineer on the back wall. A mockup of the revised control stand design was fabricated as part of this program to demonstrate the human factors and ergonomic improvements. Researchers conducted structured interviews with locomotive engineers to validate the user-centered design approach. The engineers engaged in interactive scenarios that assessed the functionality of the workspace. The usability results provided the opportunity to improve upon the initial NGLC user-centered design. Changes included minor relocation of controls because they were in the reach path of other controls. Certain frequently accessed controls required relocation to more accessible locations. The LCD displays were redesigned with respect to information groupings and visibility issues. Feedback revealed that the transition from mechanical operations to electronic operations will result in the loss of auditory cues inherent in mechanical operations. The researchers suggest simulating auditory cues to promote personnel transition from mechanical to electronic operations. The results of this usability assessment identify the opportunity for future R&D cab integration efforts and demonstrate the importance of user-centered design and usability assessment in these efforts.

Education Initiatives

The adoption of energy efficiency practices and increased penetration of renewable energy sources in the power system are estimated to play a key role in the decarbonization of the energy sector, helping reduce greenhouse gas emissions and ultimately fight climate change. To foster energy transition, energy education initiatives should primarily target the citizens and be designed adopting a User-Centered Design (UCD) approach and HCI methodologies. This paper describes how UCD/HCI can inform the design of citizens’ energy education initiatives by presenting a case study—the development of an information platform targeting Madeiran citizens. The article describes the design process, from ideation to prototype and validation. Methods used in each phase (card sorting, semi-structured interviews, brainstorming sessions, think-aloud protocol and surveys) are described. Results of each phase and how they have informed the following steps are presented, together with a detailed description of the resulting information platform and initial results in terms of acceptance and interaction with the system. Our initial results support the hypothesis that adopting an HCI perspective can nurture the development of energy education initiatives targeting citizens, bringing a user-centered approach to the design of such initiatives.

The replication crisis—a failure to replicate foundational studies—has sparked a conversation in psychology, HCI, and beyond about scientific reliability. To address the crisis, researchers increasingly adopt preregistration: the practice of documenting research plans before conducting a study. Done properly, preregistration reduces bias from taking exploratory findings as confirmatory. It is crucial to treat preregistration, often an online form/template, as a user-centered design problem to ensure preregistration achieves its intended goal. To understand preregistration in practice, we conducted 14 semi-structured interviews with preregistration users (researchers) who ranged in seniority and experience. We found that norms for using preregistration are uncertain, and identified four purposes people have for using preregistration. We describe how the different purposes could explain conflicting designs of existing preregistration templates, and how they may even undermine the original purpose of preregistration. We suggest opportunities to explicitly resolve these conflicts to support the different purposes of preregistration.

User Centered

A series of user-centered design methods were applied during the development of an ultrasound system. The methods included hospital site visits, interviews with sonographers, videotapes of examinations and usability testing with simulations of the console and displays. Based on user feedback and preferences, over one-hundred design changes were made to both the console and control panel. The resulting system accommodates users through an adjustable control panel and display monitor. In addition, the control panel and corresponding operator interface software reflects frequency-of-use and sequencing-of-use of functions, leading to more efficient interaction with the system.

BACKGROUND Informal care partners are essential partners in the delivery of complex cancer care services at home, and about 25% of those caring for cancer patients spend more than 40 hours a week providing services. Care partners frequently suffer psychological, behavioral, and physiological effects that can not only affect the patients’ mental and physical health, but also impair the care partners’ health. OBJECTIVE In this paper, we describe a user-centered design approach to build an mHealth smartphone app to provide support and resources to informal care partners while enabling them to remotely monitor the cancer survivor’s health for unanticipated adverse events, thereby reducing burden for clinical staff. METHODS An iterative information gathering process was conducted that included a) potential customer discussions with 138 people to assess health care value propositions and corresponding benefit modules; b) semi-structured interviews with clinicians (N=3), cancer patients (N=3) and care partners (N=3) to identify needs and interests, and; c) a 28-day beta iOS user testing with feasibility and acceptability feedback from 7 care partners in two geographically different academic cancer centers (Duke and Stanford). This study was registered on clinicaltrials.gov (NCT04018677). RESULTS The interviews conducted prior to developing the mHealth app prototype identified areas of consistency in responses between different stakeholder groups in terms of how the mobile app should work, as well as areas of difference. The beta test of the prototype indicated satisfaction with the app’s usability. Care partners preferred to focus primarily on the patient’s health and not their own, and regular surveys on the patient’s symptoms helped educate care partners and reduce their anxiety. CONCLUSIONS This study describes the user-centered design process and demonstrates the feasibility and acceptability of TOGETHERCareTM, an iOS smartphone app for informal cancer care partners. Larger studies, in various oncology populations, are needed to establish the efficacy of the app in reducing care partner burden and to facilitate critical remote monitoring CLINICALTRIAL

This work investigates the challenges and concerns faced when users set up and use web filtering systems for children, and identifies those changes, in the configuration interface and notifications, that could improve the users' experience and satisfaction. The findings of this study derived from the perception of one hundred parents on the usability of ten web filtering systems. The obtained results could represent a convenient starting point for further design-strategies oriented to facilitate the user-centered design in order to get web filtering systems easy to interpret and understand, thus helping to reduce configuration errors that create gaps in the safety of kids when using MOOCs and their integrated social tools.
