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.

Disaster relief responders aim to quickly locate and extract survivors from dangerous environments. This research explores the use of a collaborative guidance system for search-and-rescue in a complex building. We implemented and evaluated a proof-of-concept system that allowed a scene commander and responder to efficiently search a building using visual, nonverbal communication. Participants found the interface to be both intuitive and fun, and results suggest that the collaborative navigation system was effective.
In education and research, references play a key role. However, extracting and parsing references are difficult problems. One concern is that there are many styles of references;hence, given a surface form, identifyin...

What, if any, are the effects of the changes in distributed systems behavior on the social dynamics of distributed groups? The rapid evolution of cloud infrastructures, portable devices and multimedia services has enabled cooperation among strangers in online environments that lack quality of service guarantees. Group members experience delays and inconsistencies in the shared state. Previous research on delays focuses on tightly-coupled tasks and assumes that individual and group interests are aligned. In reality, individual participation in a group depends on how a participant weighs the value and the cost of cooperation. That tension is well captured in mixed-motive tasks (e.g., a social trap). A study was conducted, where 15 groups performed a loosely-coupled task that simulates social traps. Group members experienced a gradual degradation of system performance in the form of complex delays. Groups exhibited different adaptation patterns to the changes in the system behavior. There is no guarantee that group adaptation will always keep the status quo. System interventions are needed to maintain group dynamics.
