Elder Wearables Interacting Type Research Based On Affective Computing Theory

According to the statistics and projections of social demographers,the increasing trend of aging has become more and more obvious with the continuous low birth rate and the extension of the life span of the elderly,which has created various social problems.The elderly are only one segment of the population,and they should also lead healthier lives.Therefore,the research object of this paper is the living habits and emotional state of the elderly.How to solve the psychological and emotional problems of the elderly through better emotional interaction and providing the elderly with better life style is the key content of this paper.With the continuous maturity of intelligent technology and people’s demand for intelligent products,intelligent hardware has gradually become a necessary daily product for people to improve their quality of life and work efficiency.Wearable products are smart products that have developed rapidly in recent years.The biggest advantage of wearable products is that they can get close to the human body and obtain accurate data information.In this paper,wearable products are taken as the physical carrier,and emotional computing theory is combined to provide the elderly with a mental care environment.The aim is to improve elderly people’s life happiness index and reduce their anxiety through new technologies and interactive ways.In addition,emotion computing is a new field,which is similar to human emotion through understanding human semantics,actions,expressions,etc.Through the ability to obtain accurate information through wearable products,it can better predict human emotion changes and give reasonable feedback.In the experiment part,physiological signal experiment is mainly adopted,because the carrier of the product is wearable product,which has the advantage of obtaining accurate signals.Three physiological data including skin electrocardiogram(GSR),ECG(ECG)and EMG(EMG)were used for the experimental parameters.The first is to obtain the original data,and after data processing,establish a feature extraction model according to the type of signal.At the same time,the weight proportion is designed according to the intensity of emotion,so as to obtain the accuracy of emotion signal.At last,through the form of questionnaire,the user’s subjective emotional experience is asked,and the correlation between the user’s subjective experience and the objective experimental data is analyzed by function.Based on psychology,affective computing theory,user research and interaction design methodology,this paper aims to construct a new interaction mode mechanism and a character-specific emotional model.In addition,data analysis,character modeling,literature analysis,questionnaire research and user interview are adopted in the user research.In this paper,the concept of emotion computing theory and wearable devices are analyzed in theory,then through a lot of study and life,scene analysis,studies the elderly emotional change under different emotional scene,so as to establish a particular emotion model,the final output emotional need and the mapping relationship between the product function.The thesis illustrates four key points: Emotional measurement analysis and calculation were conducted through psychological experiments,and emotional computing theory was analyzed and applied to the design and research of wearable products for the elderly.(1)Through physiological experiments,study the emotional state changes of the subjects under different stimuli,and determine the emotional change trend through electrodermal reaction,electrocardiogram reaction and electromyographic reaction.(2)To establish the old model,cognitive psychology,behavior and emotion in close communication with the elderly,through face-to-face interviews and online interview,research a lot of the cognitive psychology and behavior and the analysis of the life of old people,the purpose is to study the elderly emotional change under different emotional scene,so as to establish a particular emotion model,the final output emotional need and the mapping relationship between the product function.(3)Design a set of wearable products were designed: head-mounted and hand-mounted,respectively.The interactive interface of the wearable products was also designed. At the same time,a gesture operation mode and wearable voice communication workflow were also designed,which fully reflected the product care for the elderly.The final concept prototype of the product is proved to be highly effective by some elderly people,which further meets their living needs and improves their happiness index.
