Summary form only given. In Japan, Home Helpers provide home welfare and care services for the elderly, such as cooking, bathing, washing, cleaning, shopping, etc. We developed a web-based home service support system using wireless Internet mobile phones and Internet client computers with liquid crystal tablets. The liquid crystal tablet is used as an entry device for elderly persons' care requests. The client computer sends the requests to the server computer in the Home Helper central office, and then the server computer automatically transfers them to the Home Helper's mobile phone. The developed home welfare and care services support system is easily operated by elderly persons and enables Home Helpers to save a significant amount of time and extra travel.
