Abstract

The invention discloses a touch reproduction device based on the bi-directional frictional force control. The device comprises a touch reproduction module, a piezoelectric ceramic stimulation module, a central control module, an electrode array stimulation module, a finger position detecting module and a communication interface module, wherein the touch reproduction module comprises a rigid touch panel, a piezoelectric ceramic array module and an electrode array module; the piezoelectric ceramic array module is arranged on the lower surface of the rigid touch panel; the electrode array module is embedded into the inner part of the rigid touch panel, and a wider, finer, and more flexible touch reproduction module is realized. The invention further discloses a touch reproduction method based on the bi-directional frictional force control. According to the method, through touching the rigid touch panel by a finger, the air squeeze film effect is achieved between the finger and the rigid touch panel, and the electro-vibration effect is achieved between the finger and the electrode array module; the bi-directional friction force coefficient adjusting and friction force coefficient fine tuning are implemented, and further the touch reproduction based on the friction force control is realized.

Description

technical field [0001] The invention belongs to the field of tactile reproduction human-computer interaction, and in particular relates to a tactile reproduction device and a tactile reproduction method based on two-way friction force control. 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 actua...
