Summary: In this paper, we report on the evaluation of a remote assistance platform
(RAP) that is designed to enable an expert to remotely assist a field operator.
A user study with 16 participants was conducted to evaluate its usability with
two assembly tasks that varied in their complexity. As part of the assessment,
we compared the interaction behavior of our platform with a commercial instant
messaging application, which lacked the ability to augment or view video
imagery. The results identified differences in the completion times between the
two conditions, as we examined the use of visual augmentation, including
recommendations to improve the platform.

Summary: In this paper, we describe a user study that compared the design of three
visual interfaces (i.e. Text, AR and a 2D Schematic view) to support the wire
harness assembly of electrical wires in modern aircraft. Displayed on a
portable iPad, 18 participants were instructed to route three sets of wires on
a commercial aerospace formboard. Through video analysis, the results
identified significant differences in the mapping time, and number of visual
references made in viewing information on the three interfaces. In particular,
a lack of graphical information in the Text, and camera alignment issues in the
AR conditions demonstrated noticeable limitations in interaction. We briefly
discuss these findings.

Summary: In this paper, we present the findings of a two month exploratory game study
in which we compared the verbal and non-verbal communication practices of two
independent groups of older adults. Among other factors, these groups differed
in their education, technology literacy and physical functioning. Through
observational measurements, we outline significant differences and trends in
players' paired interaction, which progressively changed through prolonged
exposure to the game. By comparing player performance both within and between
groups, we raise questions and provide some insights as to how differences in
the backgrounds of older players can influence dyadic interaction in collocated
play.
