Design Of Navigation Gloves Based On Vibration Tactile

Tactile as a special sensory channel of the human body,it not only realizes all-round perception of objects,but also expresses information that is difficult to perceive by visual,auditory and other channels under certain conditions.Therefore,the study of tactile perception characteristics and related tactile expression techniques is of great significance.In this paper,the tactile information expression characteristics are experimentally studied.The tactile channel is introduced into the driving navigation task.The identification and adaptability of the tactile channel in practical application are studied.The specific work is divided into the following three parts:Firstly,by analyzing the existing navigation tasks and the characteristics of each channel of the human body,it is found that the sense of touch has direct and rapid response to external stimuli.Introducing tactile cues into the navigation design can reduce the visual cognitive load,select the human hand as the vibration tactile receiving part,and propose the design of the bicycle navigation system based on the vibrotactile sense.The identification and adaptation problems based on the vibrotactile navigation mode are analyzed and expounded.Then,through the analog navigation function and riding navigation system provided by the Gaode map software,various navigation instructions are collected.According to the function,the navigation instructions with the same attributes are sorted and summarized,and the navigation instruction sets of 4 categories and 11 classes are obtained.Finally,according to the principle of maneuvering-display consistency,three types of vibrator tactile navigation modes based on vibrotactile navigation mode are proposed and the tactile navigation information coding corresponding to each navigation command is designed.Through analysis and comparison,the arrangement of seven vibrators was selected;Through the Arduino development board,IDE and other software and hardware to design a wearable glove based on vibration tactile navigation,and through three test experiments to verify the identification and adaptability problems based on the vibration-based tactile navigation mode.
