“…SAT measured users' satisfaction with IFOREAL, which has also been used to measure VR users' subjective evaluation of systems (e.g., [3], [40]). Four semantic items borrowed from Bhattacherjee's [13] classical study on information system continuance were asked: How did you feel about your overall experience of the system use?…”

The researchers of this study designed a new virtual reality (VR)-assisted training system, IFOREAL, for gynecology students at their university and introduced it to potential trainees. Two versions of IFOREAL, each employing different devices, were developed. The consumer version uses a traditional LCD display and computer mouse, whereas the professional version utilizes a head-mounted display (HMD) and joystick controller for the virtual learning. Trainees watched simulated videos and interacted with the system to accomplish tasks. IFOREAL consists of several major learning modules of gynecology. This study used the normal spontaneous delivery module to research user experience and perceptions of the IFOREAL VR training system. The results suggested that most of the trainees' user experiences and perceptions of IFOREAL, using both the types of VR-assisted technology, were positively reported. Trainees who used the consumer version of IFOREAL perceived a stronger internal control, whereas trainees using the professional version perceived a better sense of virtual presence. Overall, trainees perceived the usefulness of the IFOREAL system which predicted their future intention to use the system and other similar VR-assisted training systems for learning. Furthermore, whether the virtual content of IFOREAL grabbed the trainees' attention predicted their future intenon to use professional devices of HMD/joysck for learning other subjects. The gender difference was also explored in the study. Generally speaking, female trainees gave better evaluations of IFOREAL compared to their male counterparts. They perceived a better internal control while using the consumer version than the professional version. Male trainees believed that the gadgets used in the professional version provided a better virtual presence and met their expectation of a virtual experience better. This study suggested that different versions of IFOREAL could serve trainees' different needs. Technology developers and trainers should tailor the application of different VR devices to assist with the training/learning in accordance with different conditions/trainees.

The advent of virtual reality technology has provided a new approach for assessing and training cognitive processing ability, with the design of simulations used to replicate real events in everyday lives. To better understand how head mounted displays/flat screen displays (HMDs/FSDs) and differences in the individuals who use them affect cognitive performance and the use of VR systems, our research group created the Stroop task-embedded virtual reality driving system (STEVRDS) and conducted a 2 × 2 between-group factorial design experiment among college students. The study examined the effects of HMDs and FSDs that differ in monovision/stereovision and field of view, the impact of gender (males vs. females) on users' performances in virtual driving and Stroop trials, and users' psychophysiological responses while using the system. The participants' subjective perceptions toward STEVRDS were also assessed to support the analyses/interpretations of cognitive performance, as well as provide empirical data relating to user experiences. The statistical analyses showed both main and interaction effects of HMDs/FSDs and gender on task performance, psychophysiological responses, and user evaluations of the system. The psychophysiological patterns exhibited during the use of STEVRDS further extended the findings. Overall, our results were comparable with cognitive phenomena reported in other studies/in real-life experiences or explained by logical reasoning, which suggests that the design/development of the STEVRDS is suitable for cognitive assessment/training. Practical implications are discussed for the application of HMDs and FSDs in evaluating and enhancing cognitive processing ability and the need for specific tailoring for male and female users.
