In this paper, we present our efforts related to the implementation of the prototype that utilizes gesture based interaction for supporting collaborative explorations of visualizations in technology-enhanced learning activities. The prototype enables the visualization of different types of geo-tagged content and sensor data collected using mobile devices. In order to test the novelty and interactivity of our prototype we conducted a user testing study involving university students. The results of this study indicate that participants experienced this prototype as easy to use, with an acceptable overall level of satisfaction. Outcomes from this study show that gesture based interaction become useful when it comes to collaborative explorations of visualizations for supporting learning activities.
