摘要

本研究以Block（2007）所提出的「開放空間」為出發點，企圖檢驗3種強烈視覺運動典型鏡頭：（一）多重方向同時運動、（二）龐然大物出入鏡、和（三）搖晃的鏡頭，是否可以讓觀眾在觀賞電影或動畫的過程中產生「開放空間感」。據此，本研究分別檢驗2種自變數：環境因子（螢幕所涵蓋的視野角度）和形式因子（是否為前述3種典型鏡頭），反應時間和正確回報率被視為2項依變數。結果顯示：（一）環境因子所影響的受測者注意力未呈現顯著差異；（二）在動畫刺激方面，典型鏡頭顯著地影響受測者在「搖晃鏡頭」的表現；（三）在電影刺激方面，典型鏡頭僅僅在「30°最佳視野」情境中顯著地影響受測者在「龐然大物出入鏡」的表現。（四）本研究所得僅部份地支持Block的觀點。

The ＂Open Space＂ proposed by Block (2007) was used by this study as the beginning to investigate the three typical shots formed by strong visual movement on screen: (1) multidirectional movement, (2) movement in or out of frame, and (3) random camera movement. This study sought to understand if these typical shots give the viewer a ＂sense of open space＂ while watching a film or animation. For this reason, this study examined two independent variables: Environment factor (the field of view covered by the screen width) and Form factor (whether it is one of the three typical shots described above). Reaction time and correct rate of reporting were treated as two dependent variables. The results showed that: (1) subjects' attention performance was not significantly influenced by environment factors; (2) for animation stimulus, typical shots significantly influenced subject performance in ＂random camera movement＂; (3) for film stimulus, typical shots only had a significant influence on subject performance during ＂movement in or out of the frame＂ in the ＂30o optimal view＂ scenario. (4) The results of this study only partly supported Block's proposal.
