學習者對螢幕移動圖像之舒適度及視知覺偏好研究

A Study on Comfort and Visual Perceptive Preference of Screen Moving Images for Learners

本研究以大學生為調查對象，並以螢幕圖像為主軸，運用不同的移動速度、不同的圖像尺寸及不間的圖像移動方向等變化類別，進行各項實驗調查，以了解不同移動圖像的認知是否有差異，並探討具舒適度的螢幕移動圖像之要素。本研究以19吋螢幕為例，受試者感覺較舒適的螢幕移動圖像尺寸是4cmx4cm、感覺較舒適的移動速度是2秒（螢幕距離／秒）、感覺較舒適的移動方向是往左上方或右上方移動的圖像。令大學生感覺較不舒適的螢幕移動圖像尺寸是10cmxl0cm，較不舒適的移動速度是5秒（螢幕距離／秒）、較不舒適的螢幕移動方向是往螢幕下方移動的圖像，其結果可提供螢幕移動圖像介面設計者參考依據。

This study aims to understand the variations in the relationships between cognition and imagery of different dynamic images, based on their moving speed, size, moving direction, etc. The results showed that there are variations in readers’ cognition concerning each moving image change. Taking a 19-inch screen as an example, college students will feel comfortable if the image is moving to the top left of the screen. College students will feel comfortable if the image size is 4cm×4cm. Readers will feel comfortable if the image speed is 2sec. College students will feel uncomfortable if the image is moving to the bottom of the screen. College students will feel uncomfortable if the image size is 10cm×10cm. College students will feel uncomfortable if the image speed is 5sec. The study results can provide reference for screen image designers.
