Android 1.6 52comes with a built-in screenreader called TalkBack that provides 53spoken feedback when using Android applications written in Java. 54</p> 55<p> 56The next few videos will progressively introduce TalkBack, 57SoundBack and KickBack, a suite of programs that augment the 58Android user interface with alternative output. 59</p> 60<p> 61All of these special utilities are available through option 62<i>Accessibility</i> in the Android Settings menu. Once activated, the 63accessibility settings are persistent across reboots, i.e., you 64need enable these tools only once. 65</p> 66 67<p> 68Notice that because I have accessibility enabled on my phone, 69all user actions produce relevant auditory feedback. Thus, each 70item is spoken as I 71move through the various options in the settings menu. The spoken 72feedback also indicates the state of an item as appropriate. 73</p> 74<p> 75Activating SoundBack produces non-spoken auditory feedback; 76KickBack produces haptic feedback. 77</p> 78</div> 79<div id="postamble"><p class="author"> Author: T.V Raman 80<a href="mailto:raman@google.com"><raman@google.com></a> 81</p> 82<p class="date"> Date: 2009-03-30 Mon</p> 83<p>HTML generated by org-mode 6.08c in emacs 23</p> 84</div></body> 85</html>
