Abstract: Many devices are configured to present alerts notifying a user of device events, but the user may not notice the alert due to a noisy environment. A user may mitigate missed alerts by increasing the alert volume or choosing a vibration mode, but such techniques depend upon the knowledge, attention, and memory of the user to adjust the device before the alert. Instead, a device may compare the noise level of the environment with a noise level threshold. If the noise level is below the threshold, the device presents the alert; but if the noise level is above the threshold, the device defers the presentation of the alert until the noise level diminishes below the threshold, and then presents the alert. The device may also send an automated response to the message, notifying a sender that the user may return the message upon leaving the noisy environment.

Abstract: One or more techniques and/or systems are provided for surfacing scheduling conflicts and/or for facilitating appointment scheduling based upon conflict detection. A user may maintain user appointment data comprising user appointments (e.g., calendar entries within a work calendar). Because user activity may not be fully reflected in the appointment data (e.g., no calendar entries for routine grocery shopping, soccer practice, etc.), potential conflicts may exist between user appointments and the true availability of the user. Accordingly, user signals (e.g., email(s), location check-ins, etc. associated with soccer practice) may be evaluated to generate a user inferred behavior pattern that may be used to identify a potential conflict with a user appointment (e.g., where the user consents to the gathering and/or use of such user signals). A warning of the potential conflict may be surfaced to the user (e.g., a Tuesday dinner calendar meeting conflicts with routine soccer practice on Tuesday evenings).

Abstract: A method for displaying an information collection includes collecting a plurality of user signals associated with a user of a device, and identifying a first subject from the plurality of user signals. The first subject has at least a first piece of information. A connection between the first subject and a second subject is determined, and a second piece of information from the second subject is determined. The second piece of information is relevant to the first piece of information. The first and second pieces of information are assembled into a user information collection.

Abstract: One or more techniques and/or systems are provided for determining a user work schedule. A user may seldom update actual work hours, such as within a calendar, to reflect an actual schedule of the user, which may result in erroneous information being exposed to services that may notify other users as to when the user is inside or outside work hours. Accordingly, user signals (e.g., a current device location, execution of a work-related app, access to a work VPN, participation in a conference call from home, etc.) may be evaluated to generate a set of user activity patterns that may be indicative of recurring work patterns of the user. A user work schedule for the user may be determined based upon the set of user activity patterns. The user work schedule may be used to modify user interfaces (e.g., a conferencing website, a phone app, etc.) exposed to other users.

Abstract: One or more techniques and/or systems are provided for constructing a complementary calendar and/or a shadow calendar. A user may maintain a primary calendar within which the user may schedule user specified tasks and/or meetings, but may inadvertently omit other entries. Accordingly, a complementary calendar may be constructed based upon inferences derived from user signal data (e.g., information used to identify/infer activities of the user, such as social network profile information, messages, temporal information, locational information, documents, etc.). The complementary calendar may be automatically populated with entries corresponding to inferences derived from user signals and/or real-time conditions (e.g., weather, store hours, traffic conditions, etc.). The primary calendar and the complementary calendar may be merged to create a shadow calendar.

Abstract: Architecture that enables shared social selection by multiple participants of a route (or routes) to a physical destination based at least in part on estimated time-of-arrival (ETA) of the participants to the destination as a group, and joint selection of the destination as a group. The individuals of the group may travel from different locations and along same or different routes to the destination. The architecture assists in planning shared (and/or separate) routes to the destination and estimating the time the group as a whole will be together at the destination. The ETA for the group can be based on the person of the group estimated to arrive at the destination last in time. Interaction capabilities (e.g., texting) are facilitated between group members as part of the navigation system, and dynamic destination decisions can be based on user locations, calculated routes, and/or the type of destination.

Abstract: An embodiment of the invention provides a sentient environment that adapts itself to a person present in the environment responsive to active and/or passive expressions of preferences by the person.

Abstract: Architecture that manages a location guestbook by enabling a user to add a review based on actually having visited the location. The location of the user can be validated as part of ensuring that the user visited the location. If a user did not actually visit the location the user is not allowed to add a review in the guestbook. The architecture can also identify that a user has left the location (checked out), and hence, suggest to the user to add a review for the location. If a user has visited the location multiple times, the user review is given a higher weighting, and hence, can be considered more reliable.
