Modern handheld devices are equipped with a high-speed CPU and a 3D graphic accelerator that enrich experience to a similar level as for Desktop Virtual Reality (VR). This research explored relationships between situation awareness and presence that affect performance on a handheld game console. The task was to shoot down enemy aircraft in a flight simulator game. Situation awareness (SA) was measured by SAGAT (Situation Awareness Global Assessment Technique), while presence was measured by PQ (Presence Questionnaire) Version 3.0. Performance was measured by the number of enemy aircraft shot down per minute during aerial combat in the flight simulation game. Situation awareness was positively significantly correlated with performance. The correlation between presence and performance was also significantly positive. Presence and SA were positively related. Research on situation awareness, presence, and performance can be conducted even on a handheld game console. The study also proved that the domain of research on situation awareness and presence can be extended to small displays, such as handheld game consoles.
