On the basis of the inverse perturbation method and the calculation formula of its perturbation parameter ε, which are proposed to solve the eigenvalue inverse problem, a method of visualizing the inverse perturbation parameter ε by human-computer interaction is given. It is easy to play the role of engineering technician, Which is helpful to deal with the frequency restricted area of complex engineering systems. The corresponding software is compiled. The examples show the feasibility and effectiveness of the method
