BML:

Head

Element: <head></head>
Time Markers: start, attack, sustain, end
Attributes: id, lexeme (Shake, Nod or Tilt), repetition

The lexeme attribute is usefull when no references are given. Greta will thus match the first signal in the library using the given lexeme. &lt;source lang&#61;&quot;xml&quot;&gt; &lt;head end&#61;&quot;2&quot; id&#61;&quot;p1_0&quot; lexeme&#61;&quot;nod&quot; start&#61;&quot;0&quot;&gt; &lt;description priority&#61;&quot;1&quot; type&#61;&quot;gretabml&quot;&gt; &lt;reference&gt;Nod_Big&lt;/reference&gt; &lt;intensity&gt;1.000&lt;/intensity&gt; &lt;SPC.value&gt;1.000&lt;/spc.value&gt; &lt;TMP.value&gt;0.400&lt;/tmp.value&gt; &lt;FLD.value&gt;0.000&lt;/fld.value&gt; &lt;PWR.value&gt;0.000&lt;/pwr.value&gt; &lt;REP.value&gt;0.000&lt;/rep.value&gt; &lt;OPN.value&gt;0.000&lt;/opn.value&gt; &lt;TEN.value&gt;0.000&lt;/ten.value&gt; &lt;/description&gt; &lt;/head&gt; &lt;/source&gt;

Gesture

The gestures have been extended in Greta with expressivity parameters. Therefore, when using a gesture in Greta, we are using the following extended BML description. 

&lt;gesture id="g01" lexeme="performative=refuse_Ges_L" start="2" end="5"&gt;
	&lt;description priority="1" type="gretabml"&gt;
		&lt;reference&gt;performative=refuse_Ges_L&lt;/reference&gt;
		&lt;intensity&gt;1.000&lt;/intensity&gt;
		&lt;SPC.value&gt;0.646&lt;/spc.value&gt;
		&lt;TMP.value&gt;-0.400&lt;/tmp.value&gt;
		&lt;FLD.value&gt;0.000&lt;/fld.value&gt;
		&lt;PWR.value&gt;0.000&lt;/pwr.value&gt;
		&lt;REP.value&gt;0.000&lt;/rep.value&gt;
		&lt;OPN.value&gt;0.000&lt;/opn.value&gt;
		&lt;TEN.value&gt;0.000&lt;/ten.value&gt;
	&lt;/description&gt;
&lt;/gesture&gt;

Torso 

&lt;greta:torso xmlns:greta="gretaNameSpace" end="10" id="torso1"
	lexeme="BackwardSagittalRightLateral" start="0.000"&gt;
	&lt;description priority="1" type="gretabml"&gt;
		&lt;reference&gt;BackwardSagittalRightLateral&lt;/reference&gt;
		&lt;intensity&gt;1.000&lt;/intensity&gt;
		&lt;SPC.value&gt;0.000&lt;/spc.value&gt;
		&lt;TMP.value&gt;0.000&lt;/tmp.value&gt;
		&lt;FLD.value&gt;0.000&lt;/fld.value&gt;
		&lt;PWR.value&gt;0.000&lt;/pwr.value&gt;
		&lt;REP.value&gt;0.000&lt;/rep.value&gt;
		&lt;OPN.value&gt;0.000&lt;/opn.value&gt;
		&lt;TEN.value&gt;0.000&lt;/ten.value&gt;
	&lt;/description&gt;
&lt;/greta:torso&gt;

Shoulders

Standard BML does not allow for defining shoulders movements. For this reason the tag shoulders has been added. The shoulders movement can defined along two axes.

NAMESPACE:
ELEMENT: <shoulders></shoulders>
SYNC POINTS: start, attackPeak, relax, end, Core extensions overshoot
ATTRIBUTES: id, lexeme, amount, repetition, side, sync attributes
CONTENTS: none

Example: Raise both arms for 2 seconds.
