do you know of any commandline usability / improvement research?
jyothi: I don't know any to precisely point to. But one area where commandline usability is of key interest is in mobile phone services operating on USSD.I used to consult for a startup in India where number of users on USSD outnumber WAP. We used to constantly make a lot of tuning on the screens of the application and the workflow analysing the usage. I however don't have any papers or scholarly material to point.
