One-dimensional approach to viscoelastic material stiffness calculations

Accurate models of human body tissues and organs have tremendous applications in the medical field. Modeled organs within virtual environments are increasingly being used as research tools in medicine. In the near future, these research tools will make their way into teaching and clinical practice. These virtual environment simulations allow researchers to study the behavior of human organs and to develop large databases of organ characteristics. The 3D viewing and interaction available through virtual reality make it possible for physicians to practice many medical procedures without ever touching a patient. The main goal of this study is to evaluate the effectiveness of a 'sensory data glove', developed by the authors, for calculating the stiffness of an object beneath a surface of varying stiffness.
