Video glasses have previously been reported to be an effective instrument for emotion induction or for reducing pain perception. In the present study, we assessed the application of video glasses within the affective picture viewing paradigm. Possible advantages of this new method were tested by a comparison with a commonly used video projector. Twenty-four participants viewed sustained picture series of pleasant, neutral, and unpleasant valence with video glasses and with a projector on different days. Affective report, heart rate (HR), and skin conductance level were measured. The results showed that the video glasses presentation mode is not generally superior to the projector mode. Instead, typical responses to prolonged presentations of emotional pictures were obtained across both modalities with valence-modulated pleasure ratings and with an arousal modulation for arousal ratings, skin conductance level, and HR. These results suggest that video glasses are as useful for presenting prolonged affective picture series as are projectors. Specific contexts in which the application of video glasses is preferential are discussed.
