The popularity of watching movies and videos on handheld devices is rising, yet little attention has been paid to its impact on viewer behaviour. Smartphone spectatorship is characterized by the small handheld screen as well as the viewing environment where various unrelated stimuli can occur, providing possible distractions from viewing. Previous research suggests that screen size, handheld control, and external stimuli can affect viewing experience; however, no prior studies have combined these factors or applied them for the specific case of smartphones. In the present study, we compared smartphone and large-screen viewing of feature films in the presence and absence of external distractors. Using a combination of eye tracking, electrodermal activity measures, self-reports, and recollection accuracy tests, we measured smartphone-accustomed viewers’ attention, arousal, engagement, and comprehension. The results revealed the impact of viewing conditions on eye movements, gaze dispersion, electrodermal activity, self-reports of engagement, as well as comprehension. These findings show that smartphone viewing is more effective when there are no distractions, and smartphone viewers are more likely to be affected by external stimuli. In addition, watching large stationary screens in designated viewing environments increases engagement with a movie.

在手持设备上观看电影和视频的受欢迎程度正在上升，但很少关注其对观众行为的影响。智能手机观众的特点是手持屏幕小，以及观看环境，其中可能发生各种无关的刺激，从而可能分散观看的注意力。先前的研究表明，屏幕尺寸，手持式控制和外部刺激会影响观看体验。但是，以前没有研究将这些因素结合起来或将其应用于智能手机的特定情况。在本研究中，我们比较了在存在和不存在外部干扰因素的情况下，智能手机和功能电影的大屏幕观看。结合使用眼动追踪，皮肤电活动测量，自我报告和回忆准确性测试，我们测量了智能手机习惯的观看者的注意力，唤醒程度，参与度和理解力。结果揭示了观看条件对眼睛运动，注视分散，皮肤电活动，自我参与的自我报告以及理解的影响。这些发现表明，在没有干扰的情况下，智能手机观看效果更好，并且智能手机观看者更容易受到外界刺激的影响。此外，在指定的观看环境中观看大型固定屏幕会增加电影的吸引力。这些发现表明，在没有干扰的情况下，智能手机观看效果更好，并且智能手机观看者更容易受到外界刺激的影响。此外，在指定的观看环境中观看大型固定屏幕会增加电影的吸引力。这些发现表明，在没有干扰的情况下，智能手机观看效果更好，并且智能手机观看者更容易受到外界刺激的影响。此外，在指定的观看环境中观看大型固定屏幕会增加电影的吸引力。
