3.3 “Look At This” Queue
The other useful feature of the system is its ability to `point
out' things to users without actually marking the document.
Often in a group collaboration session, users will want to
indicate items and locations to other group members. For
example,look at this figure on page 45". When working on a
single document or machine, this process is straightforward:
the user can simply point out the section they are looking at
with their finger. Assuming all members of the group have
visual access to the same shared document or screen, they
will easily see the required information.
