addition of one feedback modality (haptic, visual or auditory) feedback improves the task performance as compared to no force feedback.low environmental detail reduces decision time and increases efficiency, but may increase error rates (Sellner, Hiatt, Simmons & Singh, 2006).stereoscopic displays increase efficiency and decrease error rates (Park & Woldstad, 2000) and improve spatial judgement (Yeh & Silverstein, 1992) as compared to monoscopic displays.-increased latency (time between event happening and event being visually perceivable by user) leads to slower movements and thus increases the time to task completion (Mateo, Gilkey & Cowgill, 2007) fidelity of visual representation: depth cues, levels of environmental detail.higher frame rates result in better task timing and fewer errors (Massimino & Sheridan, 1994), especially with inexperienced users (Liu, Tharp, French, Lai & Stark, 1993).
in operation of uninhabited ground vehicles, providing users with a third person camera perspective can make up for deficiencies in first person view (Pazuchanics, 2006) system responsiveness: frame rates, temporal delay.wider field of view leads to increased efficiency and lower error rates (Pazuchanics, 2006).Previous findings on the different error feedback modalities are summarized in tables 1-4.
