1. An accessory device for an electronic user device comprising a display screen, the accessory device comprising:
- circuitry for sensing flow of breath exhaled by a user upon a first opening in an external first surface of the accessory device;
circuitry for communicating with the user device to control a user interface on the display screen of the user device based on the flow of breath; and
a housing that encloses the circuitry for sensing flow and the circuitry for communicating with the user device, the housing of the accessory device being separate from and external to an external housing of the user device enclosing the circuitry of the user device, the housing of the accessory device comprising a first passageway connecting the first opening to a second opening at a second surface of the accessory device opposite the first surface to enable flow of exhaled breath striking the first surface to the circuitry for sensing flow, wherein the housing of the accessory device is configured to expose the display screen for viewing by the user and comprises an elastic material configured to hold the external housing of the user device within the elastic material of the housing of the accessory device, using tension of the elastic material.

9. An accessory device for an electronic user device having a display screen, the accessory device comprising:
-
at least one processor communicatively coupled to circuitry for sensing flow of breath exhaled upon a first opening of an external first surface of the accessory device and communicatively coupled to circuitry for communicating with the user device to control a user interface on the display screen of the user device based on the flow of the fluid; and a housing that encloses the circuitry for sensing flow and the circuitry for communicating with the user device, the housing of the accessory device being separate from and external to an external housing of the user device, the housing of the accessory device comprising; a cavity to hold the circuitry for sensing flow and the circuitry for communicating with the user device, the cavity comprising a second surface opposite the first surface, the second surface comprising a second opening, and a first passageway connecting the first opening to the second opening to enable flow of exhaled breath from the first opening of the first surface through the circuitry for sensing flow, wherein proximity with the user device of the circuitry for communicating with the user device is maintained by mutual attraction of two or more magnets within separate but adjacent portions of the housing of the accessory device. - View Dependent Claims (10, 11, 12, 13, 14)

15. A process of manufacturing an accessory device for an electronic user device comprising a display screen, the process comprising:
-
providing a housing comprising a first opening in an external first surface of the housing coupled by a first passageway to a second opening on a second surface of an internal cavity, the second surface opposite the first surface, and a third opening on a third surface of the cavity opposite the second surface, the third opening coupled by a second passageway to a fourth opening on an external fourth surface of the housing, to permit flow of exhaled breath striking the first surface outside of the housing through the housing and through a fluid flow sensor, wherein the housing of the accessory device is configured to expose the display screen for viewing by the user and is molded of an elastic material configured to hold the housing of the user device within the elastic material of the housing of the accessory device using tension of the elastic material; and placing circuitry comprising the fluid flow sensor for sensing flow of exhaled breath and circuitry for communicating with the user device within the cavity in alignment with the second opening and the third opening to enable flow of the fluid into the housing through the first opening, through the fluid flow sensor, and out of the housing through the fourth opening.
