Note that talking 53applications can come from many sources, with project Eyes-Free 54being but one such source. For other exciting talking 55applications that use our open Text To Speech (TTS) APIs, see 56the Android Marketplace, where you will find many useful tools 57that integrate seamlessly with Marvin. 58</p> 59<p> 60when you install the Eyes-Free Shell, you can choose to make 61Marvin your default <u>home</u> screen — this means that pressing 62the <u>home</u> button always brings up the Marvin shell. To return to 63the default Android home screen, hold down the <u>back</u> button for 643 seconds or more. 65Here is a brief description of the Marvin user interface. 66</p> 67 68</div> 69 70<div id="outline-container-1.1" class="outline-3"> 71<h3 id="sec-1.1">1.1 Single Touch Access To Useful Tools</h3> 72<div id="text-1.1"> 73 74 75<p> 76The Marvin shell uses the <a href="./02-strokes.html">Stroke Dialer</a> 77to provide single touch access to useful tools right from the 78home screen. 79You can explore this interface by moving 80your finger around the screen — as you move over the <i>buttons</i>, 81Marvin speaks the associated action. Lifting up the finger 82executes the current action. As an example, 83the top row of the keypad, i.e., <u>1</u>, <u>2</u>, and <u>3</u> 84provide status information. 85Stroking to <u>4</u> brings up your favorite <i>short-cuts</i>, and <u>6</u> 86speaks your current location using geo-location information 87obtained from Google Maps. 88Pressing <u>7</u> connects to your voice-mailbox, and pressing <u>9</u> 89puts the phone in <i>airplane mode</i> 90— this disables all wireless connections, and helpfully shows a 91large airplane on the screen to satisfy your friendly airline 92crew when flying. 93Finally, the applications that appear on the <i>shortcuts</i> screen 94can be customized by editing XML file 95<pre class="example"> 96/sdcard/eyesfree/shortcuts.xml 97</pre> 98on your SD-Card — as is apparent, this is a <i>power-user</i> feature:-)! 99</p> 100 101 102</div> 103</div> 104 105</div> 106 107<div id="outline-container-2" class="outline-2"> 108<h2 id="sec-2">2 Talking Mini-Applications For Single Touch Access</h2> 109<div id="text-2"> 110 111 112<p> 113Here, we demonstrate some of the talking mini-applications that 114can be accessed from the Marvin screen. 115All of these mini-applications speak useful information without 116the need for the user to do some form of <i>context switch</i>. 117</p> 118 119 120 121</div> 122 123<div id="outline-container-2.1" class="outline-3"> 124<h3 id="sec-2.1">2.1 Device State</h3> 125<div id="text-2.1"> 126 127 128<p> 129Available from <u>1</u> on the Marvin screen, this mini-application 130announces useful information such as signal strength, and 131availability of WiFi networks. 132</p> 133</div> 134 135</div> 136 137<div id="outline-container-2.2" class="outline-3"> 138<h3 id="sec-2.2">2.2 Date And Time</h3> 139<div id="text-2.2"> 140 141 142<p> 143Available on <u>2</u> on the Marvin screen, this mini-application provides single-touch access to current 144date and time. 145</p> 146 147</div> 148 149</div> 150 151<div id="outline-container-2.3" class="outline-3"> 152<h3 id="sec-2.3">2.3 Battery State And Power</h3> 153<div id="text-2.3"> 154 155 156<p> 157Pressing <u>3</u> on the Marvin screen speaks the current battery 158level and announces if the phone is presently being charged. 159</p> 160 161</div> 162 163</div> 164 165<div id="outline-container-2.4" class="outline-3"> 166<h3 id="sec-2.4">2.4 Knowing Your Location </h3> 167<div id="text-2.4"> 168 169 170<p> 171Available as <u>6</u> from the Marvin home screen, 172this mini-application announces your present location based on 173information acquired via GPS and the cell network.
