We explore the feasibility of using crowd workers from Amazon Mechanical Turk to identify and rank sidewalk accessibility issues from a manually curated database of 100 Google Street View images. We examine the effect of three different interactive labeling interfaces Point, Rectangle, and Outlineon task accuracy and duration. We close the paper by discussing limitations and opportunities for future work.
In this paper we describe CTArcade, a web application framework that seeks to engage users through game play resulting in the improvement of computational thinking (CT) skills. Our formative study indicates that CT sk...

In this paper, we describe a study-in-progress aimed at evaluating and improving the quality of online deliberation. We analyze the use of rationales in article deletion discussions on Wikipedia. Our preliminary findings suggest that the majority of participants in these discussions were concerned with the notability and credibility of the topics, and for the most part presented cogent rationales based on established site policies.

A touchpad has been the most popular pointing device for laptop computers. As large, multi-touch sensing touchpads are now common, we came to think about extending its input vocabulary by adding area gestures. In order to explore this possibility, we constructed a laptop-like mockup with an optical, proximity sensing touchpad, and implemented a few area gestures that may be useful in such an environment. We conducted a user test and ran a task walkthrough with a realistic scenario in order to verify the feasibility of the area gestures in a laptop environment. Copyright 2012 ACM.

With the ongoing growth of digital media, academic presses and journals have had to answer some hard questions about the role of publishing in a world of blogs, social media, on-demand video and social networking. In this panel we bring together some of the top editors and publishers in HCI to explore and address these questions in a public forum.

Mixed Reality (MR) simulation, in which a Virtual Reality (VR) system is used to simulate both the real and virtual components of an Augmented Reality (AR) system, has been proposed as a method for evaluating AR systems with greater levels of experimental control. However, factors such as the latency of the MR simulator may impact the validity of experimental results obtained with MR simulation. We present a study evaluating the effects of simulator latency on the equivalence of results from an MR simulator and a real AR system. We designed an AR experiment which required the participants to visually follow a virtual pipe around a small room filled with real targets and to find and identify the targets which were intersected by the pipe. We show that, with a 95% confidence interval, the results from all three simulated AR conditions fall well within one standard deviation of the real AR case.
