Abstract

The invention discloses a wide friction-control haptic display device and a display method based on the same. The wide friction-control haptic display device comprises a haptic display module, a piezoelectric ceramic module for excitation signal generating, an electrode array module for excitation signal generating, an electromagnet array module for excitation signal generating, a finger position detection module, permanent magnets attached to the backs of fingers of an operator, and a central control module. The haptic display module comprises a haptic panel, a transparent electrode array module, a piezoelectric ceramic array module, an electromagnet array module, a display module and a shell. Three principles, namely air pressure membrane effect, electro-vibratory effect and electromagnetic force control, are combined, increase and decrease in the friction between the fingers of the operator and the haptic display module are adjusted in a bidirectional wide range, and high-performance haptic display is achieved. The wide friction-control haptic display device is capable of sensing in multiple modes and is of great practical value.

Description

technical field [0001] The invention relates to the field of human-computer interaction of tactile reproduction, in particular to a device and method for controlling tactile reproduction with wide-width friction force. Background technique [0002] Among the human perception systems such as vision, hearing, smell, taste and force touch, force touch provides a two-way information exchange channel between humans and the environment, forming various active behaviors that cannot be realized by other sensory systems (such as touch perception). objects, manipulating tools and exploring the environment, etc.), and thus have a unique importance. At present, tactile reproduction technologies mainly include: vibration-based tactile reproduction, force feedback device-based tactile reproduction, array-based tactile reproduction, etc. [0003] Vibration-based information representation is a commonly used mode of tactile reproduction. Various vibrotactile actuators provide a solution f...
