I've tried to approximate this kind of measure in two ways: 1. Allow the participant to explore and then, in the debrief, ask who the app would be ideal for (If all is well, they say it's perfect for themselves. You can follow up with, "how would you use it?" which can still deliver all sorts of interesting surprises.)
2. Expose participant to the tool in whatever way is appropriate. Then give him/her a series of scenarios encompassing something that one might use the tool for and ask what would be the most effective (or most satisfactory--depending on what you want to know) way to accomplish the task/goal. Make sure they know they don't have to use the tool as they envision the best way to get X done. If the tool gets mentioned, make sure the participant shows you exactly how s/he envisions using it. Follow up with a question asking if the participant would actually do it the way s/he described, to make sure you get at any obstacles they might not have mentioned. marijke Marijke Rijsberman http://www.interfacility.com http://landfill.wordpress.com ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
