Cybersickness in head-mounted display (HMD) environment
Head-mounted display (HMD) is an up-and-coming tool that allows the user to immerse inside the simulator environment and gain the spatial knowledge of the environment. Recently, HMD is useful as a learning tool for the young novice driver to improve their driving skills. One of the problems related to the use of simulator is the occurrence of simulator sickness or cybersickness. The occurrence of cybersickness may undermine the effectiveness of driving training using a driving simulator. This study investigates the cybersickness severity when using HMD to display virtual environment in a driving simulator. We also investigate what strategy should be undertake to minimize the effect of cybersickness when using HMD.
Study on body cooling strategies in alleviating heat stress and heat strain in hot and humid environment
Physical works, such as firefighting, industrial activities, military drills and operations, and sports, causes body temperature to rise in proportion to metabolic heat production. When the core temperature increases rapidly and exceeds the permissible limit for work in a hot environment, the human body will suffer heat stress resulting in reduced working performance and performance impairment. Therefore, body cooling strategy is necessary to combat heat stress and to alleviate heat strain. This study sought to investigate the possible solution of body cooling strategy using the available resources in Indonesia, such as edible oil as PCM, crushed ice, and coconut water.
Study on mobile navigation systems on trust, situation awareness, and driving performance
The use of navigation system has further expanded, not only to support drivers while driving in unfamiliar locations, but also to do route-check prior to driving to avoid traffic congestion. A navigation system allows drivers to check the routes to determine the fastest or easiest route among several route alternatives provided by the system. In human-computer interaction, Human-Computer Trust (HCT) is essential since it will influence the use of information provided by the system and affects effective interaction between the user and the computer (information agent) in a complex system. In addition, navigation system also has the potential to divert the driver's attention from the driving lane and reducing situational awareness (SA) and driving performance. This study sought to investigate the relationship among trust in navigation system, SA, and driving performance.
Study on situation awareness in sleep deprived young drivers
In this study, we focus on how situation awareness would affect driving performance in sleep deprived condition. We employed the physiological and behavioral approach in analysing the situation awareness in sleep deprived condition. From the physiological approach, we investigated how sleep deprivation influenced brain activity (measured using EEG) and nervous systems (measured using HRV) and how these physiological parameters correlated with situation awareness and driving performance. We also studied the visual attention (measured by using an eye tracker device) in sleep deprived condition and how it correlated with situation awareness and driving performance. Next, we investigated several countermeasures available to improve situational awareness for those identified as having sleep deprivation symptom.
