Selective notification delivery based on user presence detections

A system comprising:

• a device profile database that stores device profiles for computing devices associated with the user, wherein the computing devices associated with the user include a first device and a second device;
• and
• at least one hardware processor in communication with the database, the at least one hardware processor configured to execute computer-executable instructions to at least:
• receive, over a network, first interaction information from the first device associated with the user, wherein the first interaction information indicates that (a) the first device received voice input via a microphone of the first device, (b) the first device detected movement, or (c) the first device determined that a mobile computing device associated with the user was in physical proximity of the first device;
• receive, over the network, second interaction information from the second device associated with the user, wherein the second interaction information indicates that (a) the second device received voice input via a microphone of the second device or (b) the second device determined that the mobile computing device associated with the user was in physical proximity of the second device;
• determine that a notification should be presented to the user regarding a reminder associated with the user;
• determine a first user presence confidence score representing a likelihood that the user is currently located in physical proximity of the first device based on a detection time of the first interaction information;
• determine a second user presence confidence score representing a likelihood that the user is currently located in physical proximity of the second device based on a detection time of the second interaction information;
• based on a comparison of the first user presence confidence score and the second user presence confidence score, determine that the user is more likely currently located in proximity to the first device than the second device;
• and
• send an instruction, to the first device over the network, that causes the first device to audibly present the notification.

A computer-implemented method comprising:

• as implemented by one or more computing devices configured with specific executable instructions,
• receiving a first indication of user presence associated with a first voice-capturing device, wherein the first indication of user presence identifies a first time that a user was detected in proximity of the first voice-capturing device;
• receiving a second indication of user presence associated with a second voice-capturing device, wherein the second indication of user presence identifies a second time that the user was detected in proximity of the second voice-capturing device, wherein the second time is later than the first time;
• identifying a meeting notification to be presented to the user;
• determining that the user is more likely to be currently located in physical proximity of the second voice-capturing device than the first voice-capturing device based on a comparison of the first time and the second time, wherein determining that the user is more likely to be currently located in physical proximity of the second voice-capturing device than the first voice-capturing device is based further on a first confidence level associated with the first indication and a second confidence level associated with the second indication;
• and
• causing the second voice-capturing device to audibly present the meeting notification.
