3.25. Time_Gen - General Timing

3.25.1. Description

Records, in general terms, where gestures fall in relation to the whole utterance

3.25.2. Format

entry     ::=  value_set [op value_set]*
value_set ::=  null | value [set_op value]*
value     ::=  "B" | "M" | "E" | "W"
null      ::=  "X"
set_op    ::=  "/"
op        ::=  ";"

3.25.3. Values

Code	Meaning	Description
B	Beginning	Gesture overlaps with the beginning of the utterance but does not last until the end
M	Middle	Gesture is performed entirely within the utterance
E	End	Gesture overlaps with the end of the utterance but not the beginning
W	Whole	Gesture overlaps with the whole utterance
X	Null	Null for some reason
NA	Not applicable	Not applicable for some other reason

Ops are drawn from the following set of operators:

Op	Meaning
;	Separates all codes
/	Used to combine representational codes into single units
,	Used to create a list of values

3.25.4. Vertical Dependencies

None

3.25.5. Horizontal Dependencies

Time_Gen is dependent upon the Time (Gesture) Column and the Enum Column.

General timing translates the values found in Time (Gesture) to a simplified code that indicates the extent and position of overlap between gesture and speech. The conversion works as follows:

-Determine the highest number associated with a word in the Enum column, N

-If an entry in Time (Gesture) begins with 0.5 or 1 and ends with a value

that is less than N, the matching Time_Gen entry is B.

-If an entry in Time (Gesture) begins with a value greater than 1 and ends

with a value less than N, the matching Time_Gen entry is M.

-If an entry in Time (Gesture) begins with a value greater than 1 and ends

with a value that is either equal to N or N.5, the matching Time_Gen entry is E.

-If an entry in Time (Gesture) begins with 0.5 or 1 and ends with a value

that is equal to either N or N.5, the matching Time_Gen entry is W.

-If the value in Time (Gesture) is X or NA, it is the same in

Time_Gen.
