Abstract: Devices and techniques are generally described for providing a graphical user interface. In some examples, first image data may be sent to a computing device, that when rendered is effective to display a first combination of items disposed together in a first environment and a first selectable control. In some examples, first data may be received indicating a selection of the first selectable control. In various examples, a first computing device may determine first feature data representing the first image data. In some examples, the first computing device may determine second image data using the first feature data. In some examples, the second image data may be sent to a second computing device. The second image data, when rendered, may be effective to display a second combination of items disposed together in a second environment.

Abstract: A swimming cap which prevents water from entering ears has a swimming cap main body; the swimming cap main body has a left side and a right side, each of which is symmetrically provided with an ear enclosing part for accommodating a human ear; each of the ear enclosing parts has an outer wall which protrudes outwards from an outer wall of the swimming cap main body; each of the ear enclosing parts has an inner wall which forms an enclosing space for enclosing the human ear which protrudes outwards from an inner wall of the swimming cap main body; each of the enclosing spaces has an outer edge which is provided with a waterproof edge in shape of an inclined trumpet at a connecting portion with the swimming cap main body. The present invention is simple and compact in structure and highly practical.
