Abstract

We present an Augmented Reality (AR) enhanced and networked fine beam tube experiment for undergraduate physics education. In order to determine the charge-to-mass ratio of the electron students are able to record all measurement values digitally within the AR-environment wearing a head-mounted AR device. Besides more accurate determination of $\frac{e}{m_e}$ it offers the possibility to overlay additional data such as a magnetic field visualization or formulas in order to foster the students' understanding of relations between experiment and theory.
