- Purpose is to guide and support ...User profilesis to guide and support reflection by mirroring user data in the form of activities, experiences or artefacts of work, notes and insights, moods, work practices, and other concrete data sources back to the user Creation of user profiles is a mixture of automated methods and manual management - the process of editing or updating the captured data may be explicitly trigger reflection.
- Taking into account the analysation of the Y3 Apps, the results of the conducted evaluations as well as using the existing MIRROR spaces framework as underlying architecture and after having conducted a literature research – user models, learner models, open learner models and visualisaton of user models - we developed the MIRROR User Profile Concept!Datastored in the MUP can be divided into three different types, namely data about the user herself, private data, and shared data Data about the user: available to all Apps employed by this user and consists of general information about the user (e.g. name or email address) Data implicitly captured by the MIRROR Apps (e.g. contacts in CaReflect or work history in KnowSelf) as well as data explicitly inserted by the user (e.g. mood in the MoodMap or notes in a Virtual Tutor App) it is essential that the user has full control over her data by deciding for each type of captured data, whether it is private or can be shared. private data is only available for aggregations on an individual level, shared data can be used, reused, aggregated or visualized in corresponding Apps and for baselines For all shared data the user has to decide whether or not the data should be used anonymisedReusabilitymajor potential benefits of the MUP storing the data according to a defined data format, Apps are able to use and reuse data stored in the MUP shared data cannot only be reused by the App it was captured from, but also by other Apps and other users SharingSharingdata is of major relevance for reflection on the individual as well as on the collaborative and organisational level To account for different levels of sharing, settings should be very fine-grained. In order to differentiate between various types of data and ways of sharing, four different sharing options are relevant: (a) which data a user wants to share (e.g. moods are shared but not the corresponding notes), (b) for which purposes data is shared (e.g. for statistical purposes or for collaborative reflection), (c) how the data is shared (anonymously or not), and (d) with whom the data is shared Privacy and SecurityPrivacy and security are a major concern when storing data in the MIRROR spaces. - It has to be ensured that the privacy settings defined by the user via different Apps are met at all times and by all Apps. - Aggregations and visualisations based on private data should only be accessible by the individual user. - Under consideration of the specific sharing settings, shared data can be used for aggregations by all Apps and can be presented to a wider group of users (e.g. the team or the organization). - Additionally, the UP has to be secured by the developed MIRROR security arrangements. Accessibility to User Interfaces - MUP has to ensure for users complete accessibility and interaction with their data. - All MIRROR Apps have to provide user interfaces, which give users full control of their MUP and all data gathered explicitly or implicitly by the Apps. - The interface serves to manage sharing, privacy, and security settings and to visualize data.

- Two phases:1: We will focus on statistical analysis to extract information regarding the number of different Apps used by a user, provide a chronological overview of the Apps used, present the number of entries in various diaries, and further statistical analyses. 2. We will concentrate on the different types of data captured by the various Apps, in order to provide analysis on the combination of data. Combining the usage of the MoodMap App with data captured by KnowSelf, or the IAA/IMA, would also lead to new insights regarding reflection.
- Closely connected to the reflection analytic service, is the prompting service (see D6.3), which has already been developed by WP6 and can be included in the various Apps. It provides the possibility to trigger users to perform a certain action or a task. This service can either be fed by the developers themselves, to show the prompts according to the captured data, or it can use the results of the reflection analytics service to give the user’s prompts via the related Apps.
- The data administration service basically serves as interface between Apps (and thus the users) and MUP. On the one side, the service takes the data from the Apps and stores it in the relevant spaces, on the other side it fetches information from the spaces that are requested by the Apps. Depending on the App, it could either visualize or use the data corresponding to the Apps tasks. For all data transfers the service has to account for security and privacy settings defined in MIRROR spaces and the MSAM.
- The User Profile Service administers general user information, using both the user profile features provided by the underlying XMPP framework and the MIRROR Spaces concept. It is linked to a User-Profile App, which gives users full control over their data. The User Profile Service also allows the user to specify his general privacy settings, i.e., settings that are applicable to all Apps (e.g. share aggregated data with team members only). Additionally, organizational structures can be set by defining different groups (e.g. team division vs. organization) which are then used as options for sharing the captured data. Further, more fine-grained privacy and sharing settings are highly App-dependent (i.e. which type of captured data is shared with whom and in which way) and are therefore stored within the App-profiles.
