Gait acquisition and interaction device and interaction method thereof

Abstract

The invention relates to a flexible pressure sensor based gait interaction system, which comprises a bottom plate with a frame, a sensor substrate and a flexible protection layer, wherein the sensor substrate and the flexible protection layer are sequentially arranged on the bottom plate, the bottom plate is provided with a power supply module, an information processing module and a data transmission module, the sensor substrate comprises a pressure sensor array, a flexible membrane laid on the pressure sensor array and a data acquisition module arranged below the pressure sensor array. The gait interaction system can recognize 14 standard computer recognition instructions such as up, down, left, right, left-handed rotation, right-handed rotation, confirmation, cancellation, up sliding, down sliding, left sliding, right sliding, amplification and reduction. According to the invention, a gait interaction technology is utilized, foot interaction is added to computer input equipment, the work efficiency can be effectively improved, and people with upper limbs being inconvenient in movement can be enabled to realize interaction with a computer through the lower limbs. The gait interaction system solves a problem that the existing input equipment is difficult to be great in strength, poor in precise control and severe in working environment, has good adaptability to sudden impact of the foot and effectively improves the accuracy of foot motion input computer interaction recognition.

Description

technical field [0001] The invention belongs to the field of pattern recognition and intelligent systems, and relates to a gait interaction device and an interaction method thereof, in particular to a gait acquisition and interaction device based on a flexible pressure sensor and an interaction method thereof. Background technique [0002] Most of the existing computer input devices require manual operation, such as a mouse and a keyboard. The mouse is used for operations such as moving, flipping, and selecting pages, and the keyboard is used for inputting letters, characters, and symbols. In the process of long-term mixed information input, it is often necessary to use the mouse and keyboard together, and it is necessary to frequently switch the position of the right hand, which affects the input efficiency, especially for users with limited mobility in the upper limbs. However, the lower limbs of the human body, especially the legs and feet, have not been involved in the i...
