当学生对实验室环境相对陌生时，在实验室中处理化学物质对大班授课提出了挑战。在这项工作中，我们描述并演示了一种增强现实比色滴定工具，该工具可以在学生的智能手机或平板电脑上操作。它允许多个学生同时进行练习，对所做的动作做出快速反应，并正确描绘与所使用的指示剂的pH值变化相关的颜色。该工具在实验过程中注入了无与伦比的现实性，并有力地帮助学生在最少使用液体化学品的情况下获得工作台技能，从而降低了他们的操作风险，并降低了对环境的负面影响。从大学生那里收到的反馈证实了这一点，他们参与了使用该工具进行的最初的小型测试。
The handling of chemicals in the laboratory presents a challenge in instructing large class sizes and when students are relatively new to the laboratory environment. In this work, we describe and demonstrate an augmented reality colorimetric titration tool that operates out of the smartphone or tablet of students. It allows multiple students to conduct the exercise at the same time, respond quickly to actions made, and correctly depict the colors associated with changes in pH values for the indicator used. The tool imbues unparalleled realism in the conduct of the experiment and offers to strongly help students acquire bench skills with minimal use of liquid chemicals, thereby reducing handing risks for them and resulting in lower negative impacts on the environment. The feedback received from undergraduate students that participated in an initial small test exercise with the tool corroborates this.
