Temat: Cog Tool - przydatne?

Ktoś ma może doświadczenia z tym narzędziem? Jest rzeczywiście w jakiś sposób przydatne w ocenie użyteczności prototypów?

Temat: Cog Tool - przydatne?

Zainteresował mnie opis, przyjrzę się.

Z wątku na IXDA wynika, ze to bardziej narzędzie do oceny interfejsów niż prototypowania.

CogTool is basically about automating predictions of how long it would take
an expert user to perform a task or tasks on a system. You build screens
with various widgets on them and then use these screens to create one or
more scripts of how a user would perform some task in the system. The
program then estimates how long it would take an expert user to perform that
task in that manner.

It can certainly be used to model two different ways of performing a task
on the system (say with a mouse vs a keyboard. or even two completely
different flows). Then it will give you estimates of how long each task
would take an expert user to perform, along with a graph of all the various
events (moving the cursor to a target, clicking the mouse, recognizing that
the screen has changed, etc). This can help you to identify where time
savings could be found in order to make the task more efficient. It is
certainly intended to help you think critically about ways to improve
completion time as well as to compare completion times of different tasks.

Mnie właśnie zainteresował głównie ten fragment o ocenie projektu względem pewnego określonego modelu ludzkich zachowań. Wcześniej nie trafiłem na narzędzie które konfrontuje automatycznie rozwiązanie z jakimś określonym - przepraszam za wyrażenie - benchmarkiem :)
