Description

per: The Usability of TrueCrypt, or How I Learned to Stop Whining and Fix an Interface by Sumeet Gujrati & Eugene Vasserman

We suggest that those parameters should be given some reasonable default values (as TrueCrypt does) and be separated from the main workflow (which TrueCrypt does not do — see Figs. 2(b) and 2(e)).

Fig 2(e) Step 5: Container filesystem options screen

Figure 3: The single-step file container creation wizard in our modified interface. The first screen is replaced with the second when a user selects “Finish.”

The impact of doing this is evident from the modified file container creation wizard (Fig. 3), which reduced the number of steps to create a container from 5 to 1.

They also suggest small and contextual help for required parameters, especially if the user does not know.
