Humans perceive mechanical phenomena on the skin from the distribution of stimuli. In this paper, we propose TorsionCrowds, a novel tactile display that presents force stimulus distribution over a large area of the body. The system consists of multi-channel twist skin deformation modules and the passive mechanisms for fitting to the human body curve. By stimulating elements arrangement based on perceptual experiments, the user can perceive continuous force distribution in a large area of the body sharply with a high dynamic range of intensity. In the demonstration, the user can experience the force distribution from the system suitable for each scenario such as visual haptization, self-motion presentation, proprioception substitution.
