Paired Comp
Read full descriptionHide full description
「Paired Comp」は、一対比較法(paired comparison)を用いた評価実験を実施するためのアプリです。一対比較法とは、複数の対象の評価を行って尺度化を行いたい場合に、評価対象の中から2つを取り出して比較し、この比較をすべての組み合わせにおいて実施する方法です。本アプリは、比較したい対象のPDFファイルを用意するだけで、一対比較法による評価実験をiPadで実施することを可能にします。 例えば、書体の好みに関する尺度を作成したい場合、比較したい書体をPDFファイルで用意するだけで、アプリが自動的にペアを作成し、一対比較法による実験を実施してくれます。どちらが好きかを選択するサーストンの方法だけでなく、どちらがどの程度好きかを評価するシェッフェの方法にも対応しています。 なお、本アプリの開発にあたっては、文部科学省科学研究費基盤研究(A)「通常の学級で学ぶ視覚障害児のための合理的配慮に関する支援システムの構築」(課題番号16H02072)、株式会社モリサワの援助を受け、河瀬和真氏がコーディングを行いました。本アプリを開発するにあたっては、小松真也氏、草野勉氏、株式会社加賀ソルネットの協力を得ました。
