Once you have launched a 3D View by tapping on one of the 36 thumbnails in the Atlas, a menu bar displaying eight icons appears at the bottom of the screen. These icons allow you to navigate through the app and access additional content and functionality.
Home: Tap this icon to return to the Home screen and select Show, Atlas, Quiz, Gallery or Help.
Views: Tap this icon to go back to the 36 Atlas View thumbnails to choose a different 3D model to launch.
Definition: Tap this icon after selecting an anatomical structure in the View to display the definition of the selected structure. The window remains open if you select a different structure, and the definition for the most recently selected structure is displayed. To view a definition for a grouping of structures within the circulatory system, tap on a structure within that grouping. Tap on the name of the grouping in the breadcrumb trail at the top of the screen to select it, then tap the Definition icon. To close the definition window, tap the "Done" button in the top right corner of the window.
Actions: Tap this icon to access several actions for adjusting and interacting with the 3D model. Information on these specific actions is included in the Adjusting Views, Selecting Structures, and Showing, Fading and Hiding Structures help sections.
Draw: Tap this button to access the drawing feature. A window will appear showing drawing tools. Use "Marker" to draw over anatomy in the View with your fingertip. Selecting "Eraser" allows you to erase your markings manually, while "Erase All" clears all markings from the View. You can also choose to "Email" your View with your drawing, or "Save" your drawing to the Photos folder on your iPad. Exit the draw mode by choosing the "Done" button on the upper margin of the Draw window. If you exit the draw mode, your drawing will be erased, so be sure to save or email your drawing if you wish to preserve it for future reference.
Screenshot: Tap this icon to take a screenshot while in a View. You will have the option to choose "Email" or "Save." If you choose "Email," you will be prompted to enter an address for your message. Saving the screenshot moves it to the Photos folder on your iPad.
Help: Tap this icon to return to these help instructions and view a step-by-step video tutorial on the key content, features, and functionality of this app.
Search: Tap this icon to search for anatomical structures when you are in a View. To search by keyword, type three or more letters of the structure you are searching for, then tap the "Done" button or the "Return" button. Search results include the names of all relevant structures and the name of the system to which each structure belongs.
Each circulatory system search result also displays the buttons "Add/Go To" or "Select/Go To". Tapping on the word "Add" adds the structure to the View. Tapping on the word "Select" highlights the structure in the current View. You may need to reposition your view to see the selected structure if it is outside your current frame or obscured by other anatomy. Tapping on the name of the structure in the search results is another way to add or select the structure in the View.
To automatically generate a new View featuring the circulatory system structure you found via the search tool, tap on the words "Go To" in the search results. The app selects (or adds and selects) the structure and repositions the image so that the desired structure is centered in the View.
Although structures in systems other than the circulatory system (e.g. skeletal, nervous) are shown in the search results, they cannot be added to the models in this app. The full set of over 2,500 structures in 10 anatomical systems is included in Visible Body Human Anatomy Atlas, available on iTunes.
