Abstract

In recent years, actuators that handle fluids such as gases and liquids have been attracting attention for their applications in soft robots and shape-changing interfaces. In the field of HCI, there have been various inflatable prototyping tools that utilize air control, however, very few tools for liquid control have been developed. In this study, we propose HydroMod, novel constructive modules that can easily generate liquid flow and programmatically control liquid flow, with the aim of lowering the barrier to entry for prototyping with liquids. HydroMod consists of palm-sized small modules, which can generate liquid flow with the electrohydrodynamics (EHD) phenomenon by simply connecting the modules. Moreover, users can control the flow path by simply recombining the modules. In this paper, we demonstrate three applications that can be easily prototyped with liquids by recombining HydroMod. These applications showcase the characteristics of using liquids: weight manipulation, color expression, and heating/cooling control.
