The Effect of Thermal Stimuli on the Emotional Perception of Images
Thermal stimulation is a rich, emotive and salient feed-back channel that is well suited to human computer interaction (HCI), but one that is yet to be fully investigated. In this talk I will give in an overview of the research into thermal interfaces, I will pay particular attention to emotional aspects. Thermal stimulation has the potential to influence the emotional response of people to media such as images. While previous work has demonstrated that thermal stimuli might have an effect on the emotional perception of images, little is understood about the exact emotional responses different thermal properties and presentation techniques can elicit towards images. In this talk I will outline a number of user studies that investigate the effect thermal stimuli parameters (e.g. intensity) and timing of thermal stimuli presentation have on the emotional perception of images. Our studies found that thermal stimulation can increase valence and arousal in images with low valence and neutral to low arousal. Thermal augmentation of images also can reduce valence and arousal in high valence and arousal images. We also discovered that depending on when thermal augmentation is presented, it can either be used to create anticipation or enhance the inherent emotion an image is capable of evoking. Some of this work will also be presented at ACM CHI 2015.
