眼睛保衛者：與你的手機保持安全距離

Abstract

隨著科技時代的到來，電腦視覺症候群已經成為了一個常見的問題。因為智慧型手機的外型小，很多使用者沒有注意到手機與眼睛的距離，因此對眼睛的健康造成了負面影響。總是與螢幕保持安全距離可以減緩電腦視覺症候群。我們在這篇論文發表了一款手機應用程式，它利用前置鏡頭來估算手機和使用者眼睛的距離，一旦這個距離太近，它將會提醒使用者要保持安全距離。我們探索了四種不同的提醒方式：模糊、邊緣閃爍、點、推播。我們進行了使用者測試去測量這些提醒方式的滿意度、有效度、干擾度。結果顯示，我們的系統可以有效的提醒使用者與手機保持安全距離。

With the advent of the technological era, Computer Vision Syndrome (CVS) has become a common problem. Due to the small hand-held form of smartphones, many users are not aware of the distance between eyes and the device. This habit may lead to negative impacts on ocular health. Always keeping a safe distance prevents the user from CVS. In this paper, we present a mobile application that utilizes the front camera to estimate the distance between the phone and the user. Once this distance is too short, the system alerts the user. We explore four different types of warnings: Blur, Flashing Border, Spot, and Push Notification. We conducted user studies to measure satisfaction, effectiveness, and distraction of these warning methods. Our results show that our system is effective in reminding users to keep a safe distance.
