One of the most important concepts of accessible design is to increase users of products, services and environments to cover the widest range of human characteristics and capabilities. There are two possible methods on how to do it; one is to provide multiple means of information presentation or operation, and the other is to set design parameters of products etc., so that they accommodate diverse human characteristics and capabilities as much as possible. Both methods are addressed as basic strategies of accessible design to make products more accessible (i.e., used by more people). Conducting and repeating this step, products can reach an ideal goal of being universal. In this paper, the concept and methods of accessible design regarding the increase of users are discussed with some examples.
