4. Users 9 users - 6 male and 3 female
Age group - 18 to 35 (young adults)
Have prior experience in social networking and video conferencing
Students and professionals recruited through contacts

5. Data Aggregation

6. Reflection on methodology
Post-test questionnaire - results are unreliable
Think aloud - hesitation
Pre-questionnaire - only honest answers

7. User behavior
To find a function / feature, users would randomly click all over the place
“I would start clicking on random buttons until one of them told me this information.”
Confirmed observation that UI is not discoverable

8. Learnability vs. long-term usability
Product aimed at long-term usability, not aimed at new users, might accept learnability issues
But Google+ changes features and interface all the time

9. Stream

10. Stream: Post order
Users expected most recent post to be at top (reverse chronological order); in fact, there is no discernible strict order
“In order to figure out what was the most recent post, I'd have to look at all of them”
Multi-column layout makes it even less clear
Not clear how to change layout

11. Stream: Changing layout

12. Stream: Notifications
Notifications appear in multiple places:
… often with substantial lag, up to several minutes

13. The +1 button
“... this +1 button, I assume that's the 'like'... largely because of Google's media advertising.”

14. Hangouts

15. Hangouts
For the most part, our group inspection of Hangouts revealed the same types of higher severity issues that users identified

16. Hangouts Text Chat
Asked users if they expect a prompt before entering video chat.
Several users responded that they would expect a prompt/ warning before entering video call.
Once clicked video call begins without warning.
User Comment: “Yes, I would expect a prompt before the video mode comes up”

17. Video Chat (Before and After)
Hangouts video call layout and look changed from the time we did our team evaluation to the time we conducted our user tests.
Did not ultimately affect the tasks we were testing

18. Video Chat (Mute/ Unmute)
Asked users to locate mute button for both themselves and others that they are in the hangout with.
Users had difficulty identifying which mute button controls each person.

19. Video Chat (cannot unmute others)
Users thought that when they clicked on the mute button again, that they had unmuted the person they had originally muted without questioning it.
In reality the other participant in video chat was still muted.

20. No Labels (Plug and Play)
Interesting user finding: A couple of our users thought that the signal strength button was actually volume control.
As with other parts of Google+, nothing is labelled and users tend to click around for a great amount of time trying to figure everything out. Many users had a confused facial expression while doing this.
