Interaction (f)or Recall? Evaluating Recall on Large Screens

Remembering content (recall) is relevant for information and educational applications as well as advertisement. Previous research showed that the recall on large screens is increased when interacting with body gestures. Based on this finding we conducted a lab study evaluating the influence of interaction (no interaction, touch, voice) on recall. We found no significant effect, but participants subjectively favored interacting with touch, and had the impression their recall was highest using touch interaction. Thus, we recommend using interaction for drawing attention to the large screen and creating a joyful experience, but relying on other methods for increasing the recall.
