Objective: This study examined the effects of display curvature, presbyopia, and task duration on visual fatigue, task performance, and user satisfaction. Background: Although curved displays have been applied to diverse display products, and some studies reported their benefits, it is still unknown whether the effects of display curvature are pres...

Objective: The objective of the current study was to ergonomically design and evaluate the Combat Engineering Vehicle (CEV) by using a digital human modeling (DHM) tool in order to better accommodate future Korean soldiers. Background: The CEV is usually attached with a different piece of combat engineering equipment to overcome various obstacles a...

It is beneficial for the information system to provide its users a right amount of contextually important information at a right time. In order to realize this, cognitive and emotional information processing characteristics of a human should be carefully taken into consideration while designing such a system. The objective of the current study was...

The need for sustainable development has been widely recognized and sustainable development has become a hot topic of various disciplines even though the role of ergonomics in it is seldom reported or considered. This study conducts a systematic survey of research publications in the fields of ergonomics and sustainable development over the past tw...

Objective: The purpose of this paper is to find the relationship between emotion and visual search task performance. Background: It is necessary to understand the effect of emotion on visual performance, as visual information processing is critical for any kind of human-computer interaction. This study specifically investigated the change in visual...

Objective: The objective of the paper is to verify the accuracy of simulated motion from key frames and to find the way to reduce the storage taken by motion data while maintaining the accuracy of digital human modeling simulation (DHMS). Background: Digital human modeling (DHM) tools have been widely used to ergonomically design and evaluate vario...

Objective: The objective of this study is to evaluate Armored Personnel Carrier (APC) by using Digital Human Modeling (DHM) tools in order to identify ergonomic problems. Background: Ergonomic evaluation is especially important in designing tactical military vehicles, since the operator will experience significantly high cognitive and physical work...

For ergonomic design and product evaluation, a digital human model simulation (DHMS) system is widely used in many areas. In this study, a systematic method was proposed to create dynamic motions of digital human model (DHM) in the RAMSIS software, one of the DHMS systems and a case study was implemented to create ingress and egress motions in a ca...

A versatile wearable computer for drivers (VWCD) was proposed that can extend in-vehicle multi-modal display spaces. In the first development phase, LEDs, mini video displays, earphones, and vibrators were included as visual, auditory and tactile displays, and were all attached to an eyeglass frame. One electrocardiographic electrode was attached t...

The objective of this study was to find the relationship between body-seat pressure distribution and driver comfort ratings of dynamic seating experience. A total of 38 participants performed four short-term driving sessions in a commercialized vehicle. These sessions involved two driving environments (lab vs. field-based). Body-seat interface pres...

Objective: This study investigated the relationship between emotions and brain signals evoked by vehicle head-up display (HUD) images. Background: Prior studies showed that HUD images can evoke different emotions such as happy, sad, angry, disgusted, scared and neutral feelings. EEG signals have been used for a non-touch based user interface. Metho...

A digital human model simulation (DHMS) system is a useful tool to design ergonomic products and evaluate usability of different products. This study developed a systematic method to create dynamic motions of digital human models in RAMSIS ® software, and applied the method to create ingress and egress motions in a vehicle as a case study. For this...
