The invention relates to a device which allows to preferably explain and demonstrate three-dimensional objects, such as anatomic models or also models and exhibits for museums and fairs. According to the invention the model 1 is fastened to the adjacencies by at least one multiple-component force-torque measurement device 2, includes an electronic storage and evaluation unit and an optic-visual and/or acoustic indicating device. The force-torque measurement device 2 converts the forces and moments arising when the model 1 is touched into electrical measurement signals to be leaded to the electronic storage and evaluation unit, and in the electronic storage and evaluation unit the contact zone is calculated from the forces and torques detected as a result of the touch, and is communicated to the operator as a signal by means of the optic-visual and/or acoustic indicating device.
