Motion Estimation and Motion Compensation on Reducing Visual Fatigue

Participants completed the Visual Fatigue Subjective Scale questionnaire post each 30-minute gaming session (MEMC and non-MEMC). This 20-item scale assessed eye strain, headaches, perceived clarity, and general comfort, with responses analyzed to identify differences in subjective visual fatigue between conditions.

Task performance was evaluated using actions per minute (APM), defined as the number of finger interactions (taps, swipes) per minute. Participants performed tasks in a consistent gaming scenario, with data collected via screen recording and custom logging software. APM reflects interface fluidity. Metrics were compared between MEMC and non-MEMC conditions to assess technology impact.

Task performance was evaluated using average operation time (AOT), the mean duration per interaction. Participants performed tasks in a consistent gaming scenario, with data collected via screen recording and custom logging software. AOT indicates interaction efficiency. Metrics were compared between MEMC and non-MEMC conditions to assess technology impact.

EEG was recorded using the Biosemi Actiview 64-channel system (Kanjian Technique Co., Ltd., Guangzhou, China) in a dark, quiet room, with participants keeping eyes closed for 5-minute resting-state sessions pre- and post-gaming. The 64 channels included Fp1, Fz, Fp2, AF3, AF4, ..., O1, Oz, O2, M1, M2, CB1, CB2. Signals were filtered (0.5-45 Hz), artifacts removed via Independent Component Analysis (ICA), and sampled at 100 Hz, with bilateral mastoids as reference. Power spectral density (PSD) of theta (4-7 Hz), alpha (8-13 Hz), beta (13-30 Hz), and gamma (30-40 Hz) waves was calculated using discrete Fourier transform (DFT) for O1, Oz, and O2 electrodes. Average relative power and Pearson correlation coefficients for functional connectivity were computed. Pre- and post-exposure differences were statistically analyzed.

BP was measured using a Kefu electronic blood pressure monitor (Model KF-65D) with the cuff on the right upper arm, 2-3 cm above the elbow, at heart level. Participants remained still during automatic measurements, with systolic/diastolic BP recorded pre- and post-gaming (0-5 min and 25-30 min) to assess physiological impact.

HR was measured using a Kefu electronic blood pressure monitor (Model KF-65D) with the cuff on the right upper arm, 2-3 cm above the elbow, at heart level. Participants remained still during automatic measurements, with HR recorded pre- and post-gaming (0-5 min and 25-30 min) to assess physiological impact.
