Arm-Hidden Private Area on an Interactive Tabletop System

Abstract

Tabletop systems are used primarily in meetings or other activities wherein information is shared. However, when confidential input is needed, for example when entering a password, privacy becomes an issue. In this study, we use the shadowed area nearby the forearm when the user places their forearm on the tabletop. And our tabletop security system is using that hidden-area to show a confidential information window. We also introduce several potential applications for this hidden-area system.
