Research On Usability Evaluation Of Smart Medical Products For Elderly People At Hom

The development of science and technology has provided a lot of convenience to people’s lives,but not all user groups have enjoyed the convenience from the development of science and technology.In particular,the number of elderly people in China is inconvenient to increase,but there is still a large gap between institutions for the elderly and the population of the elderly.Most elderly people choose homebased care.Due to the decline of elderly’s physiological functions and cognitive ability,elderly people are unable to use medical devices at home facing different levels of use barriers.Studies have shown that elderly people meet many problems when using smart medical devices for home use.Usability evaluation can provide the possibility to solve the problems existing in using of smart medical devices for home use by the elderly.This study sorts out the construction of usability evaluation theory and usability index evaluation system,and lays a theoretical foundation for the later construction of the usability index evaluation system of smart home use medical devices for the elderly.From the perspective of users,this analyzes and researches the behavioral and cognitive abilities of the elderly,combined with usability theory,and proposes usability factors for the elderly when using smart home use medical devices,including vision,hearing,touch,operating ability,perception ability,learning ability,thinking ability,etc.From the product aspect,according to the usability analysis of smart home use medical devices in terms of ease of learning,ease of operation,easy maintenance,safety,intelligence and willingness to use,the primary usability index and secondary usability index of smart home use medical devices are obtained.Taking the household oxygen generator as an example,determining the usability index,the usability index evaluation model is constructed through the analytic hierarchy process,the weight of each usability index is calculated,and the index evaluation system is improved.From the evaluation method of the usability index,the usability secondary indicators are divided into objective perception,subjective perception,and objective categories,and the oxygen concentrator usability secondary indicators are evaluated respectively,and the secondary indicators are scored according to the constructed indicator evaluation system.Weighted calculation to get the usability score of the household oxygen concentrator.This research provides a reference for the usability evaluation of smart home use medical devices for the elderly by constructing a usability index evaluation system,and expands the theoretical research on the usability of products for the elderly.Through usability evaluation,we can find out the usability problems of existing home smart medical products,and provide a reference for improving the usability of home smart medical products for the elderly.
