Immersive Analytics with WebVR and Google Cardboard

Abstract

We present our initial investigation of a low-cost, web-based virtual reality platform for immersive analytics, using a Google Cardboard, with a view of extending to other similar platforms such as Samsung’s Gear VR. Our prototype uses standards-based emerging frameworks, such as WebVR and explores some the challenges faced by developers in building effective and informative immersive 3D visualizations, particularly those that attempt to resemble recent physical visualizations built in the community.

Creating Explanatory Visualizations of Algorithms for Active Learning

Abstract

Visualizations have been used to explain algorithms to learners, in order to help them understand complex processes. These ‘explanatory visualizations’ can help learners understand computer algorithms and data-structures. But most are created by an educator and merely watched by the learner. In this paper, we explain how we get learners to plan and develop their own explanatory visualizations of algorithms. By actively developing their own visualizations learners gain a deeper insight of the algorithms that they are explaining. These depictions can also help other learners understand the algorithm.
