Experiment Procedure

The recording of EEG and ECG data took place during the resting states (i.e., eyes closed and eyes open) and the visual stimulation sessions (i.e.,

Time (min)



A Christmas Carol (Disney, 2009)


In this clip, Scrooge met the Ghost of Christmas Past. They flew together and Scrooge was brought back to his own past as a child.

Alice in

Wonderland (Disney, 2010)


Alice ran away to catch a white rabbit and reached a place named Wonderland. There she found the Hatter; later, the Red Queen’s soldier seized him. Alice planned to escape and struggled to release the Hatter, so she presented herself as a guest and went to the Red Queen’s castle.

2D and 3D). The recording begins with the eyes-closed session. The participants were instructed to sit as relaxed as they could while they were awake. Then the participants were instructed to focus on a black fixation point displayed at the center of a white screen so that the gaze was fixed during eyes-open recording. The eyes-closed session was conducted only once, i.e., at the very beginning of the experiment, while the eyes-open sessions were done prior to each visual stimulation session.

As mentioned earlier, the visual stimulation session contained three conditions: 2D, 3DA, and 3DP. The stereoscopic 3D system requires viewing glasses, hence all participants wore a set of passive polarized glasses and active shutter glasses during 3DP and 3DA modes, respectively. However, no glasses were needed for the 2D viewing. The viewing glasses are only required during the 3D viewing modes, therefore the glasses were removed during the resting conditions and the breaks between sessions.

In addition, the participants were also instructed to minimize any physical movement as much as possible. After each recording session, they were given a 5-10 minute break, and no recording was involved during this period to allow them to rest; this also reduced the potential fatigue and drowsiness effect. However, during this time, they were asked to report their viewing experience by filling up the simulator sickness questionnaire (SSQ) (Appendix 5B). Prior to the viewing in other modes, the participants were required to perform the eyes-open test again to remove the transient effects that may be induced by the various video clips in the previous viewing sessions.
