Analysis and enhancement of human-machine interfaces using a joystick controller Academic Article uri icon

abstract

  • This article deals with performance evaluation of human operations in point-to-point displacement tasks using a joystick. Analysis of operator outputs during an experimental task revealed a pattern of partially overlapping submovements with predictable velocity characteristics and forms. A velocity-dependent gain control added to the joystick-cursor interface improved performance when compared to a conventional linear transformation. This control algorithm can be recom- mended for many similar human-machine interfaces. A specific performance evaluation was applied to estimate the characteristics of different remote control designs. This approach can be used for evaluating human-machine systems. © 2000 John Wiley & Sons, Inc.
