In this paper, an in-class activity concerned with real image formation by a converging lens in the context of accommodation in human eyes is described. In the first part of the activity, students are encouraged to experience the accommodation of their eyes in a prescribed way using simple materials. In the second part, the accommodation function of the human eye is illustrated by means of a simple demonstration.

Developed by using ARKit, a novel app which can be used to detect position in physics experiments was introduced. The ARKit relies on a new technique. The result of the experiment presented in this study was satisfactory, suggesting that the new technique can be employed in position detection experiments/demonstrations that are conducted using mobile technology. This technique has several promising advantages over video analysis.

ARKit is a framework which allows developers to create augmented reality apps for the iPhone and iPad. In a previous study, we had shown that it could be used to detect position in educational physics experiments and emphasized that the ability to provide position data in real-time was one of the prominent features of this newly emerging technology. In this study, we demonstrate an example of how real-time data acquisition can be employed in educational settings, report some of the limitations of ARKit and how we have overcome these limitations. By means of ARKit or a similar framework, ordinary mobile devices can be adapted for use in microcomputer-based lab activities.
