However, fewer than one in ten individuals report having used a fact-checking service. In this paper, we introduce Google Inject: a technology-mediated nudge that integrates, relevant to one's query, fact-checks, into the Google search results page. We report on a laboratory study that inquired into how four design variables, in particular, the number of fact-checking articles injected, their positioning, concealment and seamlessness affec...Mostrar más

OBJECTIVE In robotic-assisted laparoscopic surgery, the perception and interpretation of the visual scene poses a huge challenge for medical trainees. However, their ability to assist effectively in surgical procedures depends heavily on mastering these visual skills. Research on multimedia learning suggests that seeing an expert's eye movements during task completion as a “worked-example” (i.e., eye movement modeling examples [EMME]) may guide learners’ attention to critical areas and improve learning outcomes. The effectiveness of EMMEs in robotic surg...Mostrar más

Increasing speeds in high-speed rail heighten safety concerns, particularly as foreign object detection technologies remain limited under adverse conditions. Train drivers, as the final safeguard, must accurately perceive and respond to hazards with reduced reaction margins. This study examines how four speed classes and three cognitive abilities—attention, reaction, and learning—affect hazard perception (HP) using a high-fidelity hazard perception test (HPT) developed in Unity 3D.

In recent years, the availability of easy-to-use prototyping tools has empowered designers to create GUI designs. In parallel, a broad spectrum of usability testing tools have been proposed to support the collection of quantitative test data from crowd-testers. However, test specification and results are typically disconnected from created GUI designs and, therefore, difficult to translate into improvements. In this paper, we present TESY, a prototyping assistant integrating usability test specification and resulting test data. We implement TESY as a plu...Mostrar más

Because current construction activities are safety-critical and physically demanding, the incorporation of such autonomous technologies as robots and drones via worker–robot teaming has drawn interest from researchers and practitioners alike. However, this teaming relationship may impose additional safety concerns for future jobsites due to workers’ inappropriate trust—overtrust and/or distrust—in robots. The literature has highlighted that trust is a complicated and dynamic concept that fluctuates over time, highlighting the need to continuously underst...Mostrar más

Tag maps, a geographic extension of word clouds, represent information by mapping tags and their relationships onto corresponding regions. These maps provide valuable insights into the topics associated with specific geographic areas. Semantic relationships between tags are frequently neglected in current tag map layouts. Inspired by the benefits of semantic clustering in word clouds in guiding user comprehension, we introduce semantic clustering into tag map layouts.

Introduction Simulation-based training (SBT) is used to train medical residents before they perform procedures on patients, yet most simulators do not have reporting on their validation readily available. In SBT, there is no obvious standard for how validity tests of simulators should be conducted, or which type of validity should be used. Eye-tracking can be used to determine validity by comparing gaze patterns of physicians between the clinical and simulator environments, and between novices and experts. This exploratory study utilizes eye tracking to ...Mostrar más

Even for well-studied visual reasoning tasks such as those performed on bar charts, little is known about the cognitive strategies users adopt to solve them. Guidance systems that support users in learning visual reasoning require information on successful strategies to help unsuccessful users improve or change their strategies. We introduce the guidance paradigm of sequential visual cues (SVCs), accompanied by a differential pattern mining approach that determines relevant visual attention patterns from gaze data, and exemplified for bar charts.

Designing notifications in Augmented Reality (AR) that are noticeable yet unobtrusive is challenging since achieving this balance heavily depends on the user’s context. However, current AR systems tend to be context-agnostic and require explicit feedback to determine whether a user has noticed a notification. This limitation restricts AR systems from providing timely notifications that are integrated with users’ activities. To address this challenge, we studied how sensors can infer users’ detection of notifications while they work in an office setting. ...Mostrar más
