Development of new multimedia technologies allows us to receive better quality of audio and video content. Quality of Experience (QoE) evaluates given content from the consumer’s perspective. This measurement allows to evaluate not only visual and audible quality, but also general acceptability of provided service. QoE evaluation is getting popular between engineers, designers, retailers who wants to provide high quality content for consumers. QoE is generally evaluated subjectively by surveys. It is possible to find relationship between physiological signals measured while user is consuming audiovisual content and make the subjective evaluation of this experience. This paper investigates relationship between heart rate and QoE while user is watching 1 min duration video recordings on three different devices. Heart rate was calculated as mean RR interval for each recording. Mean RR intervals of 0.848 s, 0.869 s and 0.884 s were calculated for low, medium and high QoE device configurations, respectively. ANOVA analysis results indicates a relation between heart rate and QoE level. The results can help to develop further the investigations of QoE level and heart rate relationship for various subjective assessment, device configurations and content provided.
