detecting, using the one or more cameras or depth sensors of the wearable multimedia device, one or more second gestures performed by the user; and

determining the second user input based on the one or more second gestures.

11. The method of claim 1 , wherein the plurality of applications or services comprises at least one of:

an e-mail application or service,

a text message application or service,

a chat application or service, or

a collaboration application or service.

12. The method of claim 1 , wherein modifying the second user interface element comprises:

determining an availability of the recipient to receive messages using a first subset of the plurality of applications or services; and

visually emphasizing the first subset of the plurality of applications or services in the second user interface element.

13. The method of claim 12 , wherein determining the availability of the recipient to receive messages using the first subset of the plurality of applications or services comprises:

obtaining, for each of the plurality of applications or services, presence information regarding the recipient, wherein the presence information indicates at least one of an availability or an unavailability of the recipient to receive messages using that application or service; and

determining, based on the presence information, that the recipient is available to receive messages using the first subset of the plurality of applications or services.

14. The method of claim 12 , wherein modifying the second user interface element comprises:

determining an unavailability of the recipient to receive messages using a second subset of the plurality of applications or services; and

at least one of:

removing the second subset of the plurality of applications or services from the second user interface element, or

visually deemphasizing the second subset of the plurality of applications or services in the second user interface element.

15. The method of claim 1 , wherein modifying the second user interface element comprises:

obtaining historical data comprising previous communications between the user and the recipient;

determining that the user and the recipient previously communicated with one another using a particular application or service from among the plurality of applications or services; and

visually emphasizing that application or service in the second user interface element.

16. The method of claim 1 , wherein modifying the second user interface element comprises:

determining a quality metric for each of the plurality of applications or services; and

visually emphasizing one or more of the plurality of applications or services based on the quality metrics.

17. The method of claim 16 , wherein, for each of the plurality of applications or services, the quality metric represents at least one of:

a reliability of the application or service, or

a latency of the application or service.

18. The method of claim 1 , wherein modifying the second user interface element comprises at least one of:

modifying an order of the plurality of applications or services,

filtering the plurality of applications or services,

visually emphasizing at least some of the plurality of applications or services, or

visually deemphasizing at least some of the plurality of applications or services.

19. A wearable multimedia device, comprising:

at least one processor; and

memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:

presenting a user interface for composing a message, wherein presenting the user interface comprises concurrently presenting:

a first user interface element configured to present contents of the message, and

a second user interface element configured to present a plurality of applications or services for transmitting the message;

receiving a first user input indicating:

a recipient of the message, and

first data for inclusion in the message;

responsive to receiving the first user input:

presenting at least the recipient and the first data in the first user interface element, and

modifying the second user interface element based on the recipient;

subsequent to receiving the first user input, receiving a second user input indicating a selection of a first application or service from the plurality of applications or services presented in the second user interface element; and

responsive to receiving the second user input, transmitting the message using the first application or service.
