Town map system for sharing accessibility information using card data structure

This paper describes a town map system for sharing accessibility information. Our system's unique contribution is handling all information as card data and associating those cards with a map. Using this system, users can share information in a map-based unified way. Our system not only stores information from users, but also organizes it. Users can therefore easily make their own plan for going out by relating more than two stored cards. They can also efficiently search for necessary information. Furthermore, in order to provide reliable information, we incorporated a function in which users can give a card positive or negative comments. If a card is given a negative comment, our system might make it invisible. Through evaluation of the prototype system, it was proved that our proposed system was effective in shaping accessibility information.
