Properly perceived stereo display is often assumed to be vital in augmented reality (AR) displays used for close distances, echoing the general understanding from the perception literature. However the accuracy of the perception of stereo in head-worn AR displays has not been studied greatly. We conducted a user study to elicit the precision of stereo perception in AR and its dependency on the size and contrast of the stimulus. We found a strong effect of contrast on the disparity users desired to make a virtual target verge at the distance of a real reference object. We also found that whether the target began behind or in front of the reference in a method of adjustments protocol made a significant difference. The mean disparity in the rendering that users preferred had a strong linear relationship with their IPD. We present our results and infer stereoacuity thresholds.

In this study, we ask (1) How do children at three years old and five years old judge the reality status of AR objects? and (2) Do they exhibit information-seeking behaviors to make reality status judgments about AR?

Location-based augmented reality games have entered the mainstream with the nearly overnight success of Niantic's Pok\'emon Go. Unlike traditional video games, the fact that players of such games carry out actions in the external, physical world to accomplish in-game objectives means that the large-scale adoption of such games motivate people, en masse, to do things and go places they would not have otherwise done in unprecedented ways. The social implications of such mass-mobilisation of individual players are, in general, difficult to anticipate or characterise, even for the short-term. In this work, we focus on disaster relief, and the short- and long-term implications that a proliferation of AR games like Pok\'emon Go, may have in disaster-prone regions of the world. We take a distributed cognition approach and focus on one natural disaster-prone region of New Zealand, the city of Wellington.

Frank H. Craig (1859-1945) was superintendent of Wethersfield (Ill.) schools from 1903 to 1918. He later moved in Vermont and wrote prose and poetry about the rural communities in which he lived. These poems reflect the author's love for nature and the people and memories that brought meaning to his life.
