| With the continuous expansion of computer applications,as well as the rapid development of smart home industry,the importance of human-computer interaction technology for smart home has become increasingly important.The existing human-computer interaction can’t meet the needs of the smart home environment now and in the future.Therefore,smart home needs a new,more user-friendly human-computer interactive solution.This paper designed and manufactured a wearable human-computer interactive bracelet,the bracelet will work in the smart home as a human-computer interaction device.It’s a comprehensive system,which includes not only the basic hardware system and peripherals,but also the matching software system.The underlying hardware is responsible for the system logic control,data acquisition and other system service.In the software part,the function of data transmission and gesture based human-computer interaction are realized.The specific work of this paper includes:1)The design and manufacture of the wearable human-computer interactive bracelet.The main problem of the design of hardware platform and set up the bracelet is how to achieve the miniaturization of the bracelet hardware platform so that a practical prototype can be manufactured.At the same time,the bracelet should feature a complete foundation,complete data acquisition capabilities and sufficient support for the software algorithm.In order to solve this problem,in the process of designing the hardware platform,this paper makes a full investigation and analysis of the functional chips and finally a set of chips with high integration and strong performance is selected.And then through the multilayer wiring technology,the final prototype to achieve the size of ordinary watches.2)Based on the hardware platform,the software functions such as gesture interaction and data transmission are researched and implemented.The key to realize the gesture interactive function is to balance the factors(such as the system resources,the real-time performance of the algorithm,the usability of the algorithm,the complexity of the algorithm and so on)to make the most practical system.This paper define a set of high-practical gesture instruction set,and realize the software function of gesture sequence segmentation,gesture recognition,data transmission and so on.This paper completed the wearable human-computer interactive bracelet prototype production,and to achieve the bracelet prototype and smart home system docking.In this smart home environment,this paper conducted a multi angle test of the bracelet.The emphasis of the test is on the software algorithm.Each instruction in the gesture interactive instruction set is tested in detail.The test results show that the recognition rate of each gesture instruction in the gesture interactive instruction set is higher than 95%,and the user experience is good.Bracelet prototype has a certain practical value. |
