“…Standardizing the phone eliminated these potential sources of error. As future smartphone use and video streaming capability increase [15,17,72,73], the need to rely on study provided smartphones to deliver a video intervention will be mitigated. However, disruption of wireless services through loss, theft, service cut-off, and changing phone numbers will likely remain important considerations.…”

Love, Sex, and Choices is a 12-episode soap opera video series created as an intervention to reduce HIV sex risk. The effect on women's HIV risk behavior was evaluated in a randomized controlled trial in 238 high risk, predominately African American young adult women in the urban Northeast. To facilitate on-demand access and privacy, the episodes were streamed to study-provided smartphones. Here, we discuss the development of a mobile platform to deliver the 12-weekly video episodes or weekly HIV risk reduction written messages to smartphones, including; the technical requirements, development, and evaluation. Popularity of the smartphone and use of the Internet for multimedia offer a new channel to address health disparities in traditionally underserved populations. This is the first study to report on streaming a serialized video-based intervention to a smartphone. The approach described here may provide useful insights in assessing advantages and disadvantages of smartphones to implement a video-based intervention.

“…Other researchers (Dieberger and Frank, 1998;Nielsen, 1995) propose using metaphors to help users understand the structure of the information space as well as their movement in the space. For navigating a large information space, Nielsen notes that single metaphor is too constraining in some situations, so he advises the use of mixed metaphors to design an interface.…”

For years, metaphors have been used extensively to facilitate multiple user tasks on Web sites. Nonetheless, research examining metaphor's effects in facilitating user tasks, not to mention the proposal of the design methodology, is limited. There is disagreement about using single or multiple metaphors in designing computer systems. Regarding metaphor's long-term effects, Carroll and Thomas [Carroll, J.M., Thomas, C.J., 1982. Metaphor and the cognitive representation of computing systems. IEEE Transactions on Systems, Man, and Cybernetics, SMC 12, 107-116] claim that metaphors lose utility once users are familiar with the system. Furthermore, little evidence exists about metaphor's effects on users with differing computer experience.This researcher proposes a metaphor design methodology to examine the long-term effects of integral (single) versus composite (mixed) metaphors on subjects' information search behaviors and their effects on Internet novices and experts. Ninety-eight college students participated in this study. The findings suggest that metaphor's effects decrease over time as users become more experienced. Moreover, composite metaphors facilitate experts' searching better than novices'. q

“…From a classical standpoint, a hypermedia (Nielsen, 1996) is a directed graph, composed of nodes containing basic data information and links which define the relationships between nodes. Users navigate from node to node by following links.…”
