FIELD: physics.
SUBSTANCE: invention relates to devices with interactive user interaction. Interactive floor cell comprises: a capacitive sensor data processing unit, where the capacitive sensor is configured to detect a change in the electromagnetic field near the antenna to determine the user's touch to the glass, wherein on the glass floor plate on its inner side there is an antenna in the form of a metal strip located along its perimeter, and at least four resilient elements are installed between the housing side and the antenna, wherein the user's touch to the glass and its weight are determined by the change in the capacitance of the capacitive sensor formed by said antenna and the housing; and the capacitive sensor data processing unit determines the frequency deviation of the capacitive sensor from its resonance frequency.
EFFECT: high accuracy of determining the fact of interaction of a user with an interactive floor cell and determining the weight of pressing the interactive floor cell.
