Web-based Immersive Analytics in Handheld Augmented Reality

Abstract

The recent popularity of virtual reality (VR), and the emergence of a number of affordable VR interfaces, have prompted researchers and developers to explore new, immersive ways to visualize data. This has resulted in a new research thrust, known as Immersive Analytics (IA). However, in IA little attention has been given to the paradigms of augmented/mixed reality (AR/MR), where computer-generated and physical objects co-exist. In this work we explore the use of contemporary web-based technologies for the creation of immersive visualizations for handheld AR, combining D3.js with the open standards-based Argon AR framework and A-frame WebVR. We argue in favor of using emerging standards-based web technologies as they work well with contemporary visualization tools, that are purposefully built for data binding and manipulation.

VisSurvey.js - A Web Based Javascript Application for Visualisation Evaluation User Studies

Abstract

Visualization researchers perform user studies to evaluate the effectiveness and usability of produced visualisations. While there are different styles of evaluation, some popular techniques involve comparing the result of several parameter changes, looking how results have changed and if a change is noticeable. Developers need to display many different pictures, to a wide variety of users, while guaranteeing full coverage of all potential designs across all participants. One solution is to use static screen shots of their outputs along with popular on line surveying tools, but such a solution omits any system interactivity. Alternatively they can create their own surveying application on a chosen platform. We introduce VisSurvey.js, a JavaScript library that helps developers create evaluation studies. Developers can create user studies of their application in a web browser, and easily capture the results.

Visualisation and graphical techniques to help writers write more idiomatically

Abstract

Text visualisation is gaining popularity. Researchers have investigated methods that display the structure of documents, show how books have evolved over many editions, how words are distributed in text. But few researchers have investigated how visualisation techniques could help someone write better text documents. The goal of the writer is to create texts that are not just grammatically correct, but also idiomatic, and fluent to read. Our focus is to investigate collocations, i.e., words that have become conventional to use together (fast food vs. *quick food, collect data vs. *pick data, strong tea vs. *powerful tea, etc.) While researchers are starting to use visualisation techniques to help users write better computer programs, musicians create music, or artists be more creative, there is less research in writing. In this short paper we not only make a call for action, but we look at related work, and discuss some the main challenges and opportunities for research in this area.
