Abstract:
1. An interactive teaching and learning device which comprises: a first 3D body, a second 3D body, wherein the first and second 3D bodies are combined to a uniform 3D model which allows it to be touched by a person to explain where certain regions, spots or elements of the 3D model are situated, a first force-torque multiple-component measurement device connecting the first 3D body and the second 3D body with each other, a second force-torque multi-component measurement device firmly connecting the second 3D body with its adjacencies, an electronic storage and evaluation system, an optic-visual and/or acoustic indicating device, wherein the forces and torques measured when certain regions, spots or elements of the first and second 3D bodies are touched, are converted into electrical measurement signals to be fed to the electronic storage and evaluation unit, in which either a mathematical model having a geometry of the first and second 3D bodies and an algorithm for determining, based on the measured forces and toques, the region, spot or element touched by a person, are implemented, or a plurality of touchable spots are stored and an interpretive algorithm is implemented, which determines based on the measured forces and torques, the region, spot or element touched by a person, wherein when the first and second 3D bodies are touched by a person at the same time, the measurement signals sent by the first force-toque multi-component measurement device are assigned to the first 3D body, and a difference between the measurement signals sent by the second force-torque multi-component measurement device and the measurement signals sent by the first force-torque multi-component measurement device are assigned to the second 3D body, and wherein the optic-visual and/or acoustic indicating device indicates, in an optic-visual way and/or acoustically, the region, spot or element touched by the person.
