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.

The microblogging service Twitter has become an important, and sometimes primary, source of information for many users. As a forum for sharing news and discussing events, it can provide instant access to the latest updates, but this is not always welcome. In the case of television shows or live sporting events, for example, tweets about them may reveal spoilers to users in different time zones or who are delaying their viewing until later. More broadly, because Twitter is a broadcast medium, users may often want to temporarily or permanently hide content about a very specific given topic. In this paper, we describe the unique challenges to HCI, social computing, and computational linguistics posed by the task of building an interface that blocks all tweets about a specific event or topic. We illustrate some of the challenges through a pilot experiment run for three major television events: the 2009 NFC Championship football game, the 2010 mid-season finale of the show Glee, and the 2010 season premiere of the show 24. While simple techniques achieve very high recall (> 98%), spoilers still make it through the filter and precision is extremely poor. We conclude with a description of challenges to the community in implementing this new and increasingly important feature. 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.
