receive, from the image capture device, an image of an item located within the materials handling facility;

process the image to determine that a user has selected the item while the user is located in the materials handling facility;

in response to a determination that the user has selected the item, provide initial item information associated with the item to a wearable device worn by the user, wherein the wearable device is separate from the image capture device that captured the image of the item;

subsequent to providing the initial item information, receive from the wearable device an additional item information request;

in response to the additional item information request:

determine additional item information about the item;

select an output component, other than the wearable device, that is viewable by the user; and

send the additional item information to the output component for presentation to the user.

8. The system of claim 7 , the instructions further configured to at least:

determine that an additional action is to be performed; and

perform the additional action.

9. The system of claim 8 , wherein the additional action is at least one of initiate a purchase of the item, initiate a delivery of the item to the user, initiate a delivery of the item to a destination, or associate the item with a user account.

10. The system of claim 7 , wherein the initial item information includes one or more of an identification of the item, an author of the item, a publication date of the item, a price of the item, a size of the item, a weight of the item, an expiration date of the item, or an ingredient of the item.

11. The system of claim 7 , wherein the instructions that when executed by the processor cause the processor to determine that the user has selected the item, include instructions to at least:
