In this paper, we present a tangible display for body weight, based on floor rigidity. It displays body weight without numbers, which makes it less suitable for comparisons, while still giving the user an idea about their weight. We describe the metaphorical foundations of the concept, as well as the development of two prototypes, which implement the envisioned full-body weighing experience.

To find answers, we reconstructed prototypes commonly found in literature and continued to further evaluate different foot-related designs. On the one hand, we learned that vibrotactile feedback at the foot reduces visual attention and thus also potentially reduces stress. However, on the other hand, we found that urban space can be very diverse, and ambiguous and therefore a vibrotactile system cannot completely replace common path finding systems for pedestrians.

By squeezing it close to one's own body, the subjective intensity of a local pain is manifested in the device. Via a shove gesture, it is then transmitted to a docking station.
