Abstract
The ability of images to evoke emotions in people has been well documented in previous research, as well as the differences in the emotional perception of images when viewed on different-sized screens and device types. The ability of thermal stimuli to evoke emotions in people when used for media augmentation has also been examined. However, little is known about how thermal stimuli can be used to enhance or reduce affect in images with varying emotional properties displayed in different sizes or on different devices. To the best of our knowledge, no work has been conducted to investigate whether there is any difference in the effect thermal augmentation has on images displayed in different sizes on different device types. This paper presents two user studies to address this research gap. Study 1 explored the effect thermal stimulation has on images displayed in different sizes. Images were displayed in sizes corresponding to the full screen display of a laptop, tablet and mobile phone. In study 2, we examined whether the actual presentation device (tablet and mobile) plays a role in the emotional perception of images displayed on mobile devices. Results showed that thermal augmentation was most effective in modulating emotions in small-sized pictures (427 × 240 pixels display size) and pictures displayed on a mobile phone. Thermal stimuli also reduced emotions in medium display sizes (corresponding to the full screen display of a tablet).
Highlights
According to a recent report by the UK office of communications ([29] p. 39), short-form media are increasingly being consumed on smallscreened devices, while long-form media are still mainly consumed on large-screened devices
This study investigated the role of image presentation device on the emotional perception of images augmented with thermal stimuli
Results obtained from the quantitative analysis showed that thermal stimuli augmentation and the presentation devices used in this study had no significant effect on the emotional perception of images presented on them
Summary
According to a recent report by the UK office of communications ([29] p. 39), short-form media (images and short video clips) are increasingly being consumed on smallscreened devices (tablets/mobile phones), while long-form media (long videos and films) are still mainly consumed on large-screened devices (laptops/TVs, etc.). 39), short-form media (images and short video clips) are increasingly being consumed on smallscreened devices (tablets/mobile phones), while long-form media (long videos and films) are still mainly consumed on large-screened devices (laptops/TVs, etc.). Hou et al [20] noted that this consumer preference to utilise larger screens for long-form media may be as a result of larger screens being more immersive than smaller screens [20]. There is still, the need to improve the suitability of both large- and smaller-screened devices for electronic visual media consumption (long- and short-form media). Augmenting images presented on these devices (large- and smaller-screened devices) with thermal stimuli, which have been shown to be an affective feedback channel, has the potential to enhance media viewing experience.
