この調査から出された諸要件を整理し，配色要件に重点を置いた．また，機器を操作する上での配慮点を決めてプログラムを組んだ．このようにして，高齢者に対応する要件を満たすアプリケーションを作製した．さらに，それと比較するために，要件を緩く満たすアプリケーションと，要件を大きく逸脱したアプリケーションを作製し，3種類にした．これらのアプリケーションの比較実験を行い，高齢者がスマートフォンを使うための要件の有効性を示した．
Having arranged various requirements, we have laid emphasis on a color scheme requirement. Also, we have scheduled a program after setting consideration points for operating the devices. With these steps, an application that meets and adapts to requirements of the aged was developed. Additionally, in order to make a comparison with the application, we have also developed an application that meets most of the requirements and also an application that does not meet most of the requirements, that makes 3 applications altogether. Some comparison tests were conducted to show the effectiveness of the requirements for the aged to use smartphones.
