| ===Todays application-centric approach===
| |
| Smartphones, tablets or PCs in general handle a huge amount of data like phone call logs, contact data, videos, photos, and much more. The classic approach on mobile systems is based on the idea that the user first chooses the application to reach their goal. They have to search for data and sort the information themselves. This creates a very static and application-centric user-experience.
| |
| | |
| ===Activities and Recommendations===
| |
| Contour sets out to break with this tradition and to combine the available data with personal usage patterns and context information. The Contour project aims to provide different entry points for different situations and contexts, called activities. In a work environment for example users have different preferences than they have on the train or at the opera. So the activities can contain different resources like files, contacts, applications, informations etc.
| |
| The system provides smart recommendations based on the current context like the current geo location, time but also the current activity, active files and applications or recent action history. So the provided resources depend not only on the context, but also on the previous behaviour of the user. The system tries to learn those patterns and adjust them to the users' needs in every situation.

| === Definition of Context ===
| |
| The context includes all the information that can be gathered from the sensors like:
| |
| * Current geo location
| |
| * Time
| |
| * Surrounding sounds
| |
| * Movement of the user
| |
| * Current activity
| |
| * Active files and applications
| |
| * Recent action history (conceptually the whole history can be taken into account - the further away an action is the less relevant it is)
| |
| | |
| | |
| === Behavioral Patterns ===
| |
| * Behavioral patterns of the user like "every sunday evening at 18:00 the user calls their mother".
| |
| * Input for the patterns are the context and the actions the user takes.
| |
| * Patterns are dynamic in nature. They can change over time.
| |
| * Patterns can even be interrupted by location changes or other context changes and be picked up later (illness, vacation, ...).
| |
| * A pattern occurs if the same action is taken again and again in similar contexts. Similar here means that the contexts match with a high percentage.
| |
| | |
| === Activities ===
| |
| * The activity is the static part of the user context.
| |
| * There is always exactly one current activity.
| |
| * Actions, applications and resources have a certain distance to an activity.
| |
| * Activities can be created or removed by the user. The system can suggest new activities when the user drasticly changes the way they normally use an activity. But the system will never create activities automatically.
| |
| * In addition each activity has a corresponding device configuration. For example the phone configuration includes simple things like ring tones, wallpapers as well as more complex rules like filtering incoming phone calls
| |
| | |
| === Recommendations ===
| |
| * Recommendations are propositions for actions or information
| |
| * Dynamicly changing to context
| |
| * Based on the detected patterns (selflearning) and likes of the user (manually)
| |
| ** Which activity is likely in which context?
| |
| ** The relation between ressources (informationen, documents, applikations etc) and activities
| |
| * Can either be accepted or ignored by the user
| |
| | |
| | |
| ==== Calculation of Recommendations ====
| |
| * User context
| |
| ** Location
| |
| ** Time
| |
| ** Actions in proximity
| |
| *Usage statistics
| |
| *Resource scores
| |
| *Resource rank
| |
| *Resource distance
| |
| | |
| ==== Examples of Recommendations ====
| |
| * Contact person X
| |
| * Open file Y
| |
| * Start playing music
| |
| * Take note about the phone call just received
| |
| * Open presentation for the meeting which you just entered
| |
| * The next bus to X goes in 10 minutes
