Mobile Usability Study

For my article “Mobile PHRs compliance with Android and iOS usability guidelines”, a short mobile usability survey was conducted to validate the questionnaire in the article. The survey was created online using Google Forms and it was published on my Twitter account. Since some participants asked me if I could publish the results, here they are. The survey contained 13 questions that participants had to evaluate on a scale of 1-5 regarding their interaction with mobile applications.

Participants’ age: between 18 and 51.
