1. Both participants 1 and 2 showed no problem with finding the General Symptom Button. But both participants did not aware of Dropdown Button and could not change the gender of the human body.
2. Providing text as well as image buttons at the same time makes the participant confusing because these buttons do not feel like a coherent interface.
3. From the medical professional's point of view, general symptoms, demagogical condition (skin), and the Body Map Pathway should be the same level of choice.
4. Both participants had no difficulty clicking the body parts. However, the interaction of showing the symptom list might not be intuitive. Since the list of symptoms is positioned below the Body Map Pathway and hidden from the screen, participants have to scroll down to check the symptoms. It means scrolling down to see the list is less practical for the users.
