eprime question

[Georg Odenthal]

Hello Emma,

To get ePrime to collect String input click on the "advanced" button in
the Duration/ Input tab (after adding the keyboard as input device and
putting {ANY} in the allowable field).

In the Keyboard Advanced Properties set the maximum number of
characters allowed as input. [But be careful, backspace is also counted
as character. That is, if somebody types 5 characters and deletes them
again 10 characters are counted - that seems to be a bug in ePrime ...
or maybe a feature? ;-) So always enter a lot larger number for
allowed characters than what you really want to allow your subjects to
enter]

You can also specify a termination response, e.g. {ENTER} for the
return key.

On the Collection tab you should set the "response mode" to alphanumeric
if you don't want your subjects typing in punctuation marks.

You should leave "process backspace" to yes if you want your subjects
to be able to delete their input again. But you will have to deal with
the backspace problem described above if backspace is being processed.

Finally on the "echo" tab you have to add a screen display in order to
display the typed text string on the screen. Without a screen display
your subjects won't see what they type.

You can use the size of the screen display to limit the visible text
field. If you want your subjects to enter a maximum of 30 characters
and want them to be able to delete as many characters as possible you
should enter e.g. 999 as "max count" on the General tab and then limit
the screen display so that only 30 of these will be presented on the
screen. Then your subjects can type and delete 999 characters, but
will only see about 30 (this amount can vary depending on the
characters being typed since ePrime uses proportional spaced font) on
the screen and assume that this is the maximum they are allowed to
type.


Best regards,
 Georg Odenthal
