 6The Marvin shell pulls together available eyes-free applications
 7to provide an integrated user experience. Note that talking
 8applications can come from many sources, with project Eyes-Free
 9being but one such source. For other exciting talking
10applications that use our open Text To Speech (TTS)  APIs, see
11the Android Marketplace, where you  will find many useful tools
12that integrate seamlessly with Marvin.
13
14when you install the Eyes-Free Shell, you can choose to make
15Marvin your default _home_ screen --- this means that pressing
16the _home_ button always brings up the Marvin shell. To return to
17the default Android home screen, hold down the _back_ button for
183 seconds or more.
19Here is a brief description of  the Marvin user interface.

21** Single Touch Access To Useful Tools
22
23The Marvin shell uses the [[./02-strokes.html][Stroke Dialer]]
24to provide single touch access to useful tools right from the
25home screen. 
26You can explore this interface  by moving 
27your finger around the screen --- as you move over the /buttons/,
28Marvin speaks the associated action. Lifting up the finger
29executes the current action. As an example,
30the  top row of the keypad, i.e., _1_, _2_, and _3_
31provide status information.
32Stroking to _4_ brings up your favorite /short-cuts/, and _6_
33speaks your current location using  geo-location information
34obtained from Google Maps. 
35Pressing _7_ connects to your voice-mailbox, and pressing _9_
36puts the phone in /airplane mode/
37--- this disables all wireless connections, and helpfully shows a
38large airplane on the screen to satisfy your friendly airline
39crew when flying.
40Finally, the applications that appear on the /shortcuts/ screen
41can be customized by editing  XML file 
42:/sdcard/eyesfree/shortcuts.xml
43on your SD-Card --- as is apparent, this is a /power-user/ feature:-)!

49Here, we demonstrate some of the talking mini-applications that
50can be accessed from the Marvin screen.
51All of these mini-applications speak useful information without
52the need for the user to do some form of /context switch/.

77this mini-application announces your present location based on
78information acquired via GPS and the cell network. It speaks your
79current heading using the built-in magnetic compass, looks up the

81terms of a nearby address and street intersection.
