<p>Touch sensation is valuable in mobile augmented reality games, especially for improving experience in serious games by linking the virtual and real worlds. This study develops haptic stimuli for a mobile augmented reality serious game to enhance haptic and user experience. We designed haptic stimuli based on the game’s visual components, testing two versions: fantasy and ordinary. Three multimodal combinations (visual-audio, visual-haptic, and visual-audio-haptic) were created and evaluated in a user study to assess their impact on haptic and user experience. Quantitative findings showed significant differences in the involvement aspects of haptic experience, indicating that participants felt more involved with the fantasy version than with the ordinary version when playing with the visual-audio-haptic combination. The visual-audio-haptic combination consistently provided a better user experience in terms of attractiveness, stimulation, and novelty, regardless of the version. Qualitative feedback offered insights into future design improvements for haptic and user experience in mobile augmented reality serious games.</p>
