A Magnetic Levitation System for Contactless Controlling Display Monitor Angles and Positions

Objective: We present our research on a system that controls position and orientation of display monitors using magnetic levitation. Background: Recently people spend longer and longer time than ever for watching various types of panel displays such as computer monitors, TVs and tablet pads. Watching a monitor in a fixed posture can cause physical problems in neck and back especially when viewing angle requires an uncomfortable posture. Method: In this paper, a magnetic levitation system is introduced that provides effortless noncontact control of monitor orientation and position/height for viewing comfort. It consists of: 1) multiple (two or more) permanent magnets that provide basic levitation, 2) multiple electromagnets that generate attractive and repulsive forces, and 3) a unit that controls the electromagnets for desired position and orientation. Results: Our system can accommodate most of the panel displays currently manufactured and may provide guidance for future their design. Conclusion: Good physical posture is important to the well-being of children, hospital patients, the old and the weak. Application: Our system can also be used to enhance the emotional and aesthetic satisfaction in viewing.
