systems are increasingly used in entertainment, marketing and design and
development processes. Many of these applications involve emotional
experiences. Since momentary emotions significantly determine a user’s response
and decisions, it is essential to understand the influence of media content and
technological factors on the user’s emotional response. To measure the
emotional responses to immersive VR experiences, efficient and validated
instruments are required. Most tools currently used to measure the emotional
response of users compromise the immersive experience since they are
cognitively demanding, time consuming, and their application requires the user
to leave the VR. We investigated the validity of an immersive, efficient and
intuitive EmojiGrid graphical self-report tool for the assessment of emotions
evoked by 360º VR videos. Using the EmojiGrid, 40 participants rated 62 360º VR
videos from a validated public database. The resulting mean valence and arousal
values agree with the corresponding values provided with the database (obtained
with an alternative validated rating tool). We conclude that the EmojiGrid is a
valid self-report tool for the assessment of VR-evoked emotions
