Unknown Objects

We investigate early word-based categorization by testing one sample of infants at the ages of 14 and 16 months using an object manipulation task. Specifically, we investigate the facilitating effect of labeling on: a) categorization of unknown objects with a shared label and a similar shape; b) categorization of unknown objects with a shared label, but no perceptual similarity. The results indicate that an average infant can categorize novel objects with a similar shape and a shared label starting at 16 months of age. Categorization of novel objects with a shared label but no perceptual similarity is at chance level at both ages. These results confirm and extend previous research findings to a new language.

Perceived Usability

In this paper, we have investigated the comparative usability among three different viewing configurations of augmented reality (AR) system that uses a desktop monitor instead of a head mounted display. In many cases, due to operational or cost reasons, the use of head mounted displays may not be viable. Such a configuration is bound to cause usability problems because of the mismatch in the user's proprioception, scale, hand eye coordination, and the reduced 3D depth perception. We asked a pool of subjects to carry out an object manipulation task in three different desktop AR set ups. We measured the subject's task performance and surveyed for the perceived usability and preference. Our results indicated that placing a fixed camera in the back of the user was the best option for convenience and attaching a camera on the user�s head for task performance. The results should provide a valuable guide for designing desktop augmented reality systems without head mounted displays
