An image displayed on the selection screen when a presentation is selected (asso-
ciated to the tag imgPresSelected in architecture.xml)
For each language, an XML file describing the content of the presentation.
1 or more PowerPoint presentations
(optional) one or more sound files (WAV or MP3)
3.2.1 Main presentation file
Here is an example of the main presentation file:
<?
xml version
=
" 1.0 "
< presentation >
< language category =
< speechFile >
</ language >
< language category =
< speechFile >
</ language >
</ presentation >
It specifies for each language that the robot can use which presentation file to use. Pos-
sible languages are: French, English, Spanish, German, Italian, Chinese, Japanese, Ara-
bic, Russian.
WARNING: Languages have to be installed on the robot. Usually Nao comes with 2
languages: English and an extra language.
3.2.1.1 Selection with voice recognition
It is possible to start a presentation using voice recognition. For this you need to activate
the option UseVoiceReco in the configuration file and add keyword tags for the presen-
tations that you want to trigger containing a list of keywords separated by semicolons (for
each language), for instance:
<?
xml version
=
" 1.0 "
< presentation >
< language category =
< speechFile >
< keyword >
</ language >
< language category =
< speechFile >
< keyword >
</ language >
</ presentation >
In this example, during the selection screen, if the user says one of the keywords "nao" or
"robot", this presentation will be started.
WARNING: Each presentation must have its own set of keywords. It is strongly advised
to deactivate speech recognition in noisy environments to avoid unwanted triggering of
presentations.
