We introduce CrossY, a simple drawing application we
used as a benchmark to demonstrate the feasibility of using
goal crossing as the basis for a graphical user interface. We
show that crossing is not only as expressive as the current
point-and-click interface, but also offers more flexibility in
interaction design. In particular, crossing encourages the
fluid composition of commands making it easier to create
more fluid interfaces.
While crossing was previously identified as a potential
substitute for the classic point-and-click interaction, this
work is the first to report on the practical aspects of
implementing an interface based on goal crossing as the
fundamental building block.
