Effective human–robot interaction (HRI) requires robots to exhibit smooth, human-like head dynamics that extend beyond simple reactive control. Existing social robots often orient after stimuli occur, leading to delayed and unnatural motion. Anticipatory behavior, such as proactive head movements based on predicted sound activity, may help maintain conversational flow. However, its benefits in HRI remain insufficiently explored. To investigate this, we conduct a pilot study using Boxie, a minimal robot equipped with essential head degrees of freedom. Participants interact under multiple headmotion strategies in a conversational game. Subjective evaluations indicate that predictive head motion may enhance game experience and perceived social qualities.
