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.

Expert evaluation methods, such as heuristic evaluation, are still popular in spite of numerous criticisms of their effectiveness. This paper investigates the usability problems found in the evaluation of six highly interactive websites by 30 users in a task-based evaluation and 14 experts using three different expert evaluation methods. A grounded theory approach was taken to categorize 935 usability problems from the evaluation. Four major categories emerged: Physical presentation, Content, Information Architecture and Interactivity. Each major category had between 5 and 16 sub-categories. The categories and sub-categories were then analysed for whether they were found by users only, experts only or both users and experts. This allowed us to develop an evidencebased set of 21 heuristics to assist in the development and evaluation of interactive websites. Copyright 2012 ACM.

In this paper, we report our experience deploying the MonoTrans Widgets system in a public setting. Our work follows a line of crowd-sourced monolingual translation systems, and it is the first attempt to deploy such a system "in the wild". The results are promising, but we also found out that simultaneously drawing from multiple crowds with different expertise and sizes poses unique problems in the design of such crowd-sourcing systems.
