The results provide insight into a participatory design to guide design decisions for the type of intervention for which success relies largely on self-motivation. The results also provide recommendations for design of similar interventions that may benefit from the integration of mobile applications to Internet-based interventions. The present research contributes to the theoretical frameworks that have been formulated for the development of Internet-based applications.

We explore how users manage multi-session web tasks (tasks that require more than a single web session to complete). When users are performing multi-session web tasks, they must 'make sense' of information that they gather during each of the Web sessions and they must also 'keep a sense' of the information between the sessions. We present the results from two studies that examine how users are performing multi-session tasks and outline three prototype tools that we are currently evaluating to help users perform multi-session tasks.

Re-finding information on the Web is a common yet often time consuming and challenging task. Even with the use of traditional bookmarks, which allow users to return to a previously visited page, it can be hard to re-find facts within that page. Furthermore, it is not uncommon for users to have long and unmanageable lists of bookmarks, making it difficult to identify the purpose of individual bookmarks. In this paper, we present an extension to traditional bookmarks called landmarks, a user-directed technique that aids users in returning to specific content within a previously visited web page. We investigate the efficiency of landmarks for re-finding information on web pages and present the findings of a study in which participants were first primed on two web pages and returned at a later date to re-find the information using both traditional bookmarks and landmarks.
