Research On Human-computer Interaction Technology In Smart Home Based On Attitude Sensor

With the continuous development of Internet of Things technologies,the intelligent progress of home appliances has been in the stage of rapid development.However,the products of different merchants are independent of each other and the control methods of different home appliances are not the same.It leads to a poor user experience of household appliances.The intelligent interactive mode established in home can effectively improve the interaction experience of smart home products.Among the various ways of interaction,gesture-based interaction technology is more in line with the daily operating habits of people than traditional remote controls,and the interaction mode is more natural.It is of great practical significance to research the human-computer interaction technology in smart home.According all of the above,it carries out research on gesture interaction technology based on attitude sensor,and designs the hardware and software of intelligent home gesture interactive system.It also studies the application of human-computer interaction technology based on hand gestures in smart home.The specific work is as follows.Firstly,taking the MPU6050 attitude sensor as a hand gesture input sensing device,a data collection system for hand gestures based on the ZigBee wireless communication network is built.Through the design of a computer application of hand gesture visualization based on Unity3 D,the related research work of data collection,transmission,preprocessing,recognition based on the hand gesture is carried out.Secondly,some research work is carried out on the gesture interface for interaction in smart home from three aspects: cognition,comfort and memorability.Through simulation experiment of home appliance control,interviews and other investigation methods,the cognitive correlation between different gestures and home functions is analyzed.As a result,the interactive gestures of common household product functions are designed to improve the efficiency of human-computer interaction.Lastly,based on the above research work,a smart home interaction system consisting of a bracelet device,a control system,and some terminals is built to integrate natural and efficient gesture interaction into home appliance control.In addition,a smart home interactive simulation application software is designed to simulate the control of common household appliance functions through gesture actions.Thus,it verifies the basic functions of the humancomputer interaction intelligent home system based on hand gestures and realizes the effective control of the functions of household appliances through hand gestures.
