Visual distraction caused by in-vehicle information system (IVIS) poses a serious threat to driving safety. This study aims to determine the maximum safe text length thresholds for short and long Chinese texts displayed on central control display, based on the Visual-Manual NHTSA Driver Distraction Guidelines. A high-fidelity driving Simulator setup system and eye tracker were used to record participants’ glance behaviour while completing short- and long-text reading tasks under driving conditions. For short texts, statistical analysis indicated that a m...Ver más

The product and the booth it is displayed on are critical and essential elements influencing consumers’ aesthetic preferences for static product display images in mobile shopping contexts. This study investigates the impact of shape consistency between a smart speaker and its display booth on consumers’ aesthetic preferences, taking into account variations in product shapes and display scenes, and provides practical design guidance for product display imagery. A two-phase comparative selection experiment was conducted, employing methods including eye-tra...Ver más

This study investigates optimization strategies for smooth pursuit eye movements in eye-controlled interactive systems, aiming to enhance task efficiency and user experience. To address challenges such as visual clutter and cognitive load, a novel static-triggered smooth pursuit design is proposed. In this approach, interactive elements remain static until gaze contact initiates movement, after which they accelerate uniformly to a predefined maximum speed. The study employs an experimental methodology to evaluate the effects of three key parameters—accel...Ver más

Objective The purpose of this study is to understand what updates to the user interface (UI) of our medical training Simulator setup, the DHRT+, led to an increase in usability as defined by its three pillars—effectiveness, efficiency, and satisfaction. Background Medical error is a leading cause of death in the United States. Central venous catheterization (CVC) is a large contributor to this issue with its 15% complication rate, which is primarily linked to the experience of the physician. Current training methods for CVC are limited by inadequate prac...Ver más

Product kansei image evaluation is crucial for optimizing product design elements. Developing methods for evaluating kansei image will improve user satisfaction. Traditional methods of assessing kansei image primarily use two-dimensional images, limited by their single perspective and one-sided interaction. To overcome these limitations, this paper proposes a product kansei image evaluation method incorporating three-dimensional perspective tracking data. This study used scoliosis orthosis as an experimental sample and focused on the kansei image word “h...Ver más

Gaze data is a well-established indicator of cognitive load levels during Human-Machine Interaction. The design characteristics of virtual learning environments can be a source of extraneous cognitive load, which can, in turn, strongly impact the gaze behavior of learners. The cognitive load experienced by learners can be classified into three components: intrinsic, extraneous and germane. This study aims to systematically investigate the relations between the design of virtual reality environments, gaze data, and cognitive load. Therefore, a randomized ...Ver más

Several studies have suggested that action videogame experience improves attentional tasks, but its effects on emotional perception remain uncertain. The present preregistered study aimed to explore whether individuals classified as action videogame players (AVGPs) exhibit heightened in the presence of emotional stimuli compared to non-videogame players (NVGPs). Seventy-eight participants were assigned to each group based on self-reported gaming experience. Participants engaged in a dual-task paradigm comprising a central emotion discrimination task and ...Ver más
