However, this requires that associated features go beyond mere expectations to meet the needs and requirements of diverse audience groups. Focusing on designing games for healthy older adults, we present a study exploring the usability and acceptability of a set of three gesturebased games. Designed for a large projection screen display, these games employ vision-based techniques that center on physical embodied interaction using a graphical silhouette. Infrared detection, accompanied by back-projection is used to reduce the effects of occluded body movements. User evaluations with 36 older adults were analyzed using a combination of pre-and postgame questionnaires, direct observations and semi-structured group interviews. The results demonstrate that while all the games were usable, they varied in their physical and social engagement, perceived ease of use and perceived usefulness. In particular, items associated with physical wellbeing were rated highly. During the discussion, we highlight strengths and weaknesses of our findings, including related interaction and application features.

Players were paired together with the game objective of cooperatively nurturing and maintaining a set of virtual garden plants using a novel form of silhouette interaction. Questionnaire and observations revealed marked differences in the communicative behavior of the age groups, with higher

However, to date, most studies have been tested in controlled laboratory conditions. This paper outlines a user experience study of a wearable mobile augmented reality system in an outdoor urban environment. We describe the use case of using a see-through monocular headmounted display (HMD) with augmented imagery for orientation, and the use of gesture input for interacting with information while on-the-move. Participants had to navigate to a target location, whilst receiving information updates, and complete a series of gesture-based tasks. Despite participants managing to complete the tasks after some assistance, it was found that more improvements to the user experience are required for it to be viable in outdoor-use. In particular, better visibility, when seethrough HMDs are used in a bright environment, and improved situation awareness. This paper further highlights the difficulties in using gesture input, and points to a number of areas requiring further research into the use of wearable mobile AR systems in the context of this work.

In a game study of 36 mixed-age participants (teenagers, younger adults and older adults), we investigated three distinct types of avatars to differentiate user preferences and interests, primarily to determine if age affected the rating of these modalities. The results identified significant differences in the perceived attractiveness, homophily, engagement and expressiveness of the avatar representations across the three age groups, particularly in relation to the older adults. Moreover, we identified subjective variations in player's preferences towards the movement and customization of the avatar features designed. The implications of this work are briefly discussed.

There are advantages and disadvantages to both solutions, and which is used will largely depend on the context of use. In this paper, we present an outdoor user evaluation of an alternative wearable AR device mounted on the forearm to allow hands free movement. Findings on the strengths and weaknesses of the system along with user recommendations were obtained, and ...
