A study was conducted on the effects of improving concentration by obscuring the peripheral vision using a blindfold that only covers the left and right sides of the field of view. The blindfold was trapezoidal in shape (5 × 4.8 cm in length and width) and was fixed to the left and right sides of the glasses with fixing clips. The material was a black-colored polypropylene (PP) and weighed 2.3 g including the clip. Qualitative and quantitative evaluations were performed on 50 healthy college students during the 15 days of using a blindfold. The qualitative analysis was performed utilizing a questionnaire regarding the improvement of concentration and the structure of the blindfold. EEG was measured while watching a learning video that required attention for quantitative analysis, and signal power and ERD/S analyses were performed for the mid β band (15-20 Hz) at the F4 position, which was the frontal lobe. The results showed that 40 of the 50 people reported improved concentration when they wore a vision shield, and 80% of the total subjects found it to be effective. From the quantitative evaluation, the ERS peak (p = 0.023) and the ERD + ERS peak value showed a significant difference (p = 0.017). In conclusion, concentration still improved even if only the left and right visual fields were used. Thus, it is expected that blindfolding could be used in various environments that require concentration.

방송에서는 당사자의 동의 없이 얼굴을 노출 시키거나, 유해물질로 판단되는 물체의 노출을 금지하고 있다. 기존의 처리방식으로 편집자가 촬영된 영상을 직접 편집하거나, 촬영 시 가리개를 이용하는 방법을 사용한다. 이러한 방법은 번거롭고, 실수로 인해 얼굴이나 유해물질이 방송에 그대로 노출될 수 있다. 본 논문에서는 딥러닝 기반의 객체탐지 모델과 동일인 판단 모델을 사용하여 편집 과정을 자동으로 처리하고 후처리뿐만 아니라 실시간 방송에서의 적용을 위해 추가적으로 객체추적 알고리즘을 도입하여 처리속도를 높이는 방안을 제시한다.
