摘　　要：家用电器产品上的按键多使用电容触摸的方式,其使用环境复杂、多变,而环境变化会改变触摸系统的参数,最终导致按键不灵敏或者误动作,影响用户使用。故探讨环境中温度和湿度等因素变化时对触摸系统的影响,同时为了解决环境变化引起的按键异常问题,介绍了一种软件自适应算法方案,可有效提升触摸按键对环境变化的适应性,对家电中触摸按键设计具有指导意义。The keys on household appliances mostly use capacitive touch,and its use environment is complex and changeable,and the environmental changes will change the parameters of the touch system,eventually leading to the insensitive or misaction of the keys,affecting the user’s use.Therefore,it discusses the influence of temperature and humidity in the environment on the touch system.At the same time,in order to solve the abnormal keys caused by environmental changes,a software adaptive algorithm scheme is introduced,which can effectively improve the adaptability of touch keys to environmental changes,and has guiding significance for the design of touch keys in home appliances.
