We are developing a survival-information registration system called IAA system. The IAA system allows disaster victims to register their survival information (kind of injuries, damage to property, etc.) through the Internet. However, elderly people were hard to register survival information because they were poor at using keyboard. We developed interactive fax user interface, which allows a user to check and correct the handwritten information using paper user interface. Experimental result showed that elderly people could register their survival information without help.
