How Can Deep Neural Networks Aid Visualization Perception Research?: Three Studies on Correlation Judgments in Scatterplots

How deep neural networks can aid visualization perception research is a wide-open question. This paper provides insights from three perspectives—prediction, generalization, and interpretation—via training and analyzing deep convolutional neural networks on human correlation judgments in scatterplots across three studi…

Dually Noted: Layout-Aware Annotations with Smartphone Augmented Reality

Sharing annotations encourages feedback, discussion, and knowledge passing among readers and can be beneficial for personal and public use. Prior augmented reality (AR) systems have expanded these benefits to both digital and printed documents. However, despite smartphone AR now being widely available, there is a lack…

Portal-ble: Intuitive Free-hand Manipulation in Unbounded Smartphone-based Augmented Reality

How should we implement direct hand manipulation for smartphone-based augmented reality (AR) in larger spaces? We conduct an experience prototyping exercise to show that this may be harder than it might seem, as existing principles from prior literature were found to have issues with users. We identify i…

Evaluating Pan and Zoom Timelines and Sliders

Pan and zoom timelines and sliders help us navigate large time series data. However, designing efficient interactions can be difficult. We study pan and zoom methods via crowd-sourced experiments on mobile and computer devices, asking which designs and interactions provide faster target acquisition. We find that visua…
