Can anyone give me any suggestions on how I can conduct a user research study with a participant who is unable to share his screen or have have it recorded? He has informed me that his computer was hacked in the past and he is hesitant in doing so.
I often work on projects where for security reasons we are unable to record the participants.
We've found it best (albeit expensive) to either travel to the participant or invite them to our offices.
You can perform the same tasks, but the data you capture will not be able to be reviewed in quite the same way afterwards as it will likely by hand written. We have found you need at least 2 people, one to facilitate and one to record by hand, results, insights, comments etc.
If the issue is purely the participants reluctance using their own hardware, inviting them to your office allows you to use your own hardware which you could feasibly record from. This assumes their hardware isn't relevant to the study, e.g. you weren't expecting them to use assistive technologies for example (unless you can replicate their environment).
Instead of a moderated study where the researcher needs to look at the participant's screen, you may try unmoderated testing. A little like a standard questionaire, but there are tools out which offer typical usability methods, such as card sorting, A/B testing, prototype interactions, etc.
You'll get pointers if you look for "tools unmoderated usability test" with your favorite search engine.
One method to help with this if the user is seriously locked down, AND it HAS to be them that you research, would be a diary study with images.
Ie a diary that the user can detail exactly what they are going through, alongside images they can take of their screen at key points in the process. (screenshots or phone camera etc.)
