there are wake up call services that will ring my phone at a specific
time

but i want a service that will ring my phone at a random time

its preferable if it is programable or at least possible to shut it
off from the phone rather than from the internet

i need this for psychological/sociological experiments, i.e. at 5
random intervals during the day, note how happy you are feeling

other solutions might be acceptable

Clarification of Question by lukenosek-ga on 09 Oct 2003 00:13 PDT

if you know vxml, a vxml script would suffice.

i have a voxeo developer account, if you can double check that i can
still run such a script for free, then such a script would suffice as
an answer to this question

i'd be probably willing to pay more than $10 for it, and probably more
for additional development

lukenosek-ga,

This kind of thing is often done using a pager. The test subject
carries the pager and randomly, throughout the day, he is paged. When
the pager vibrates or rings, he records his mood. This way the system
works even when the subject is away from his desk.

Rather than automate, you just give the pager number to a couple of
people and ask them to each call you 3x during the day. With several
people doing the calling, the call times would be random.

-K~

that works if the subject does not know that live people are calling
or paging him

since i'm one of the subjects, knowing that a person is paging me will
bias the results, especially if i know the person
