Vibrations emitted by smartphones have become a part of our daily lives. The vibrations can add various meanings to the information people obtain from the screen. Hence, it is worth understanding the perceptual transformation of vibration with ordinary devices to evaluate the possibility of enriched vibrotactile communication via smartphones. This study assessed the reproducibility of vibrotactile sensations via smartphone in the in-the-wild environment. To realize improved haptic design to communicate with smartphone users smoothly, we also focused on the moderation effects of the in-the-wild environments on the vibrotactile sensations: the physical specifications of mobile devices, the manner of device operation by users, and the personal traits of the users about the desire for touch. We conducted a Web-based in-the-wild experiment instead of a laboratory experiment to reproduce an environment as close to the daily lives of users as possible. Through a series of analyses, we revealed that users perceive the weight of vibration stimuli to be higher in sensation magnitude than intensity under identical conditions of vibration stimuli. We also showed that it is desirable to consider the moderation effects of the in-the-wild environments for realizing better tactile system design to maximize the impact of vibrotactile stimuli., Comment: 8 pages, 9 figures
