Outline of Final Research Achievements

In this research, the speed and accuracy of our proposed intelligent mathematical formula input UI for mathematics e-learning has improved by using artificial intelligence technology. As a result of our evaluation, the 85% accuracy has been obtained. In addition, we have established a more flexible interface that enables reliable construction of mathematical formulas by narrowing down transformation even if it is not included in the prediction candidates. Furthermore, as advanced applications of the UI, we developed a mathematical document editor that makes it easy to digitally record mathematical documents such as thinking processes during mathematics e-learning, and built a system to support the learning process including graph creation. Through our experiments, it has been verified that the effect, efficiency, and satisfaction were higher than before. The results were presented by several articles, and the development system was released on our server.

Academic Significance and Societal Importance of the Research Achievements

既存の数式入力UIはシステムに合わせて利用者が指示しなければならないため負担が大きい。提案のインテリジェントUIは、利用者の曖昧入力を補って予測してくれる。しかし、候補算出速度・精度に問題があった。本研究の学術的意義は、それらのアルゴリズムを改善し、実用レベルに引き上げた点にある。
本研究の社会的意義は、より柔軟で数式入力の負担が大きく改善されることが期待された数学文書エディタやそれと連携するグラフ作成ツールの提供により、紙と鉛筆でしかできなかった数学ノートや途中計算過程をデジタルデバイスにより記録できる環境を学習者に提供できるようになることである。
