• Maybe list name and user name in search, highlighting what matches the users input.  I.e if the user types in Rob, result shows Rob Miller rcm, where rcm is his username and Rob is highlighted.
• The icons look grayed out.
• Consistency.  Some menus had back buttons while others did not.
• Not sure of the purpose of the search bar.  In the home map, is it to find a person or location.

• Allow people to invite their friends to an event.  Possibly use open/closed meetings.
• When inviting friends to an event you could sort them by distance or by frequency of events you attend together.
• The app is somewhere between informal and full contact management. The right way to do things may not be easy.
• The tasks were intuitive but might want to reevaluate the tasks that we are aiming for so we can identify what we are missing or how to make the app better.
• The app could possibly suggest places to meet or store personal defaults.

You have received a notification from Alice, who has invited you to an event. You know that you are only free at 6:00 P.M. You would like to propose a change to the event time to meet at 6:00 P.M. instead.

Imagine that you are Zoey, currently using Discover.Me.
You have received a notification from Alice, who has invited you to an event. You know that would only want to attend an event if it's held in Building 11. You would like to propose a change to the event location to meet at Building 11 instead.

Users had trouble identifying the Action Bar icons as buttons, indicating a lack of affordances indicating that they were indeed buttons. Users were distracted by other buttons on the action bar and search bar, which surprised the user. This may have increased the time required by our user to make the correct selection.

Users wanted a shorter process for adding one or more friends. They found the disabled buttons on the "Add a friend" window to be distracting, even though they were place there to maintain consistency. Users remarked that "Show on map" presented an ambiguous meaning, indicating a lack of exerternal consistency, and likely that the user possessed a different conceptual model of what the application would do versus what they expected it to do.  (i.e. Does it show a person's office location or their current location?) Users were surprised +when the application repeatedly returned to the home page. Users also suggested that the search feature should provide a better cue of its functionality, perhaps by presenting more +information scent as to how they ought to perform the query (i.e. search by name? or search by MIT username? or does it search all substrings and returns a set of possible candidates). In particular, they were unsure whether the search feature looked for a location or a person.  

Due to the hand-drawn nature of the fields and buttons, users exhibited apprehension and some confusion about the affordances provided by them. In particular, some users preferred tapping on the fields, while others preferred tapping on the icons which were positioned at the right-most edge of the fields. The lack of hotspots contributed to this. Users also felt that there was too much detail to be entered when creating an event, indicating that it might become an efficiency issue should they end up using the system on a frequent basis. For example, the time zone and meeting end time are unnecessary for initiating an impromptu meeting. Users also found it difficult to update events, which indicates that our application UI lacks robustness to support slight user tweaks.

Users were surprised to receive another confirmation box after sending an RSVP. They also found that the event details page lacked any visual cues as to how to begin proposing changes to the various entries. As a result, users erroneously closed the window and began searching for another way to begin proposing changes in response to the event invitation, posing a safety error.

Users were not presented this task.

The system can be intuitive at times, but forces the user to make extra clicks. There is further ambiguity about the functionality of certain features, such as  the back and close search bars.  Users searching for friend names wanted to know the level of detail applied in the search feature. For example, this additional knowledge would help them in deciding whether to search for a friend by their nickname or email address.

• [Learnability: Different Conceptual Model] 
  When the user first attempted to find Zoey in their contacts, they attempted to type in the search bar rather than going to the friends icon. 
  
  

• [Efficiency] 
  Consider implementing a bulk add, there are currently a lot of steps per friend request which will make adding a lot of people annoying.
  
  
• [Learnability: Lack of Affordance]
  The buttons look grayed out and are hard to notice.
  
  
• [Learnability: Information Scent, Feedback]
  User would like a way to confirm the person, some way of identifying that the result in the friend search was the correct person.  At the time the user had typed and the single result was Zoey.
  
• [Learnability: Lack of Affordance]
  When the user clicked the “Show On Map” button on Zoey’s profile, they were unsure whether this represented Zoey’s current location or her office.  Suggested renaming the button to something like “Where is Zoey?”  
  
  
• [Learnability: Lacking Internal Consistency,
   Safety: Non-reversible action]
  User tapped on the dot representing Zoey’s location and her info came up.  When he pressed back it returned to the home page.  The user expected it to return to the map with Zoey on it.

• [Learnability: Different Conceptual Model]
  The user clicked on the friends icon, figuring they would be able to contact them through there.
  
  
• [Learnability: Different Conceptual Model, External Consistency]
  The user was uncomfortable with a calendar for impromptu meetings since they felt that a calendar event wasn’t needed for an event in 30 minutes.
  
  
• [Efficiency]
  Felt that there was a lot to type in the event information screen.  Decided to skip putting a title to the event.
  
  
• [Efficiency, Safety]
  Suggested an add and invite button when inviting people to an event.  Eg: Was inviting Christine and Zoey to coffee when remembered they wanted to invite Miranda to coffee as well but had forgotten to add her.  Would have to back out of this menu, step through the process of adding Miranda as a friend, then recreate the event.
  
  
• [Learnability: External Consistency]
  After inviting people to the event and returning to the create event page, the invited field said “3”.  User was confused as to what this meant.  Was this three people including the user as well or were there three other people invited.  Suggested Facebook style listing: list a few guests by name then say “and X others”.
  
  
• *[Learnability, Efficiency]*
  Why is there a time zone?  
  
  
• [Efficiency]
  Wondered what the purpose of end time was for an event like coffee.  Use of end time will depend on what we expect people to do on the app.
  
  
• [Safety, Efficiency]
  At the time, the confirm location popup covered the map.  Suggested this was bad as the user could no longer see the map.  If they looked away for a second they no longer knew the location of the event.  Proceeded to tap back to examine the location.  Location was deleted when he merely wanted to double check it.

 User was not presented this task.

User was not presented this task.

• Would like to see the current location of people.
• Are the routes drawn by the map accurate?  This could be incorrect depending on when the last time the person was tracked, whether they had signal, or if there phone was on.

• [Learnability: Bad Affordances] 
  Was distracted by the other buttons other that the Friend List icon.

• [Learnability: Internal & External Consistency] 
  Would like consistency when searching for friends. Can you type their name? User name?  Consistency in the results.  Does the name come up or user name?
  
  

• [Learnability: Bad Affordances] 
  Original bright buttons on top bar did nothing.
• [Learnability, Efficiency] 
  The pins on the map should say who that pin represents.
  

User was not presented this task.

User was not presented this task.

• Consistency.  What is the user looking?  I.e the name issue
• Maybe list name and user name in search, highlighting what matches the users input.  I.e if the user types in Rob, result shows Rob Miller rcm, where rcm is his username and Rob is highlighted.
• The icons look grayed out.
• Consistency.  Some menus had back buttons while others did not.
• Not sure of the purpose of the search bar.  In the home map, is it to find a person or location.

• [Learnability: Affordances] 
  Did not exhibit difficulty in locating the Friend List icon, and picked it correctly on the first try.

• [Learnability: Different Conceptual Model] 
  The user first checked the location of their friends before creating an event, otherwise the tasks were performed as expected with little comment.
  

• [Learnability: Information Scent] 
  User indicated that the menu for "Creating an Event" looked complicated.

• [Learnability: Internal Consistency] 
  Expressed surprise that after pressing "RSVP", that a confirmation dialog asking whether the user wanted to "Accept", "Reject" or "Propose Change".

User was not presented this task.

• The system is pretty intuitive
• Occasionally there were a few extra clicks, such as the confirmation boxes
  

Users were able to identify the icons used in the Action Bar much better, due to the improved affordances provided by the images used, which resembled real-world buttons.

Users found the procedure to be intuitive. They also found it easy to complete the work flow by making selections on several consecutive pages. However, users were briefly confused when the application returned to the home page. They had expected some visual indicator in response to their selection, indicating a lack of feedback to confirm that the Add request was indeed sent.

The Notifications Icon in the Action Bar bore resemblance to speech bubbles, which made users think erroneously that it should be the way to "respond" to an event invitation. This indicated a lack of external consistency of the icon used. Users, however, would identify the Calendar Icon and correctly associate it with anything related to Events. Otherwise, the work flow was intuitive and enabled the user to complete all tasks. Some users indicated that more information could be provided by the application in helping them make a decision for selecting a location, for example, they wanted to know the distance between two locations marked on the map. 

Users quickly understood how to respond to invitations, indicating good learnability. However, some users felt the UI was too simple. In particular, making the "Accept without changes" button available even after use made resulting changes prone to error.

The map feature lacked appropriate affordances, making it unclear how to change the selected location. Some users attempted to drag the pin to change location, while some tried to click on different location. These were a result of unclear affordances of the static images on the paper prototype. Others tried tried tapping on the name. 

Users liked the ability to visualize their friends' location when creating new events. 
However, they suggested adding a feature to specify whether an event was closed or open to friends of friends.

• [Learnability: Affordances]
  User did not exhibit difficulty in locating the Friend list Button. Picked it out correctly on the first try.

• [Learnability: Misleading Affordance]
  It looks like you can edit the users profile information.
  
  
• [Learnability: Lack of Feedback]
  After the request to Zoey was sent, the user expected the app to return to the friends list showing he had sent an invite to Zoey rather than returning to the home page.

• [Learnability: Misleading Affordance]
  The notifications button looks like a messenging button.
  
  
• [Efficiency]
  If you have this information of your friends, why not just text them to meet up?
  
  
• [Efficiency]
  Liked the drop down windows for friends, events, and notifications.
  
  
• [Learnability: Confusing the User]
  Thought there were too many fields in the create event page.
  
  
• [Learnability: Unclear Affordance]
  The user took a while to notice the check boxes in the invite friends page.
  
  
• [Learnability: Unclear Affordance]
  User was unaware how to get the time wheel off the screen.
  
  
• [Learnability: Lack of Affordance, Different Conceptual Model]
  User would like to change the name of a location. When they clicked building 26, they wanted to change it to something that conveyed more information such as 26-204.
  
  
• [Learnability: Lack of Feedback]
  Would like a pop up notification that fades away informing them that the invite was sent.

• [Safety]
  Having an “Accept Without Changes” button seems error prone when changes are made.

User was not presented this task.

• User liked the idea of being able to visualize the locations of his friends when creating the event.

• [Learnability: Affordances]
  User did not exhibit difficulty in locating the Friend list Icon. Picked it out correctly on the first try.

• [Efficiency, Learnability: Lack of Feedback]
  After sending the friend invite, the user would go to friends to see some confirmation that the invite was sent.

• [Learnability: Unclear Affordance]
  Unsure how to get the time wheel off the screen.
  
  
• [Learnability: Confusing the User]
  Didn’t see much need in an end time.

User was not presented this task.

• Clicked and dragged event pin rather than clicking on a new location.

• Liked the lines connecting the people to the locations
• It was not obvious that event proposals could be changed, only knew because it was a task.
• Was not obvious that you could click the map to change the event location.
• A “Propose Change” button might make it more obvious that you can change the details of the event.

• [Learnability: Affordances]
  User did not exhibit difficulty in locating the Friend list Icon. Picked it out correctly on the first try.

• [Safety]
  User didn’t bother to read Zoey’s profile.

• [Learnability: Confusing the User]
  Don’t need to have a time zone in the event page.
  
  
• [Learnability: Confusing the User]
  Need accurate text for the search bar on map, at the time it said to search for friend location.
  
  
• [Learnability: Lacking Affordances]
  Can it show the distance of the people from the event?

User was not presented this task.

• [Learnability: Unclear Affordances]
  Couldn’t tell that you can change the event location by clicking the map.  Instead tried to click on the location field of the event notification.
  
  
• [Learnability: Unclear Affordances, Confusing the User]
  When the user got to the map to change the location they said that it didn’t seem like you could.  Assumed you could drag and drop the location pin.
  

• Allow people to invite their friends to an event.  Possibly use open/closed meetings.
• When inviting friends to an event you could sort them by distance or by frequency of events you attend together.
• The app is somewhere between informal and full contact management. The right way to do things may not be easy.
• The tasks were intuitive but might want to reevaluate the tasks that we are aiming for so we can identify what we are missing or how to make the app better.
• The app could possibly suggest places to meet or store personal defaults.

Users no longer had problems identifying the top row of buttons as buttons they should be tapping on to launch sub-menus, indicating that they were providing better affordances as buttons. Users also were drawn to the search bar in order to identify if a friend was currently present in the Friend List. The idea that the search bar should be used to look for someone, and not simply check the Friend List indicated that the users had a different conceptual model as to how the system should be used. Some wanted the menu icons to perhaps have text, or better information scent, to make them confident that they were going into the right menu. The icons used were generally recognized as "Friends", "Calendar" and "Conversation", indicating that there was some external consistency in their usage. As a result, most users learnt by doing/exploring.

Most users had no difficulty identifying the "plus"-icon being the button that had to be used in order to begin adding a new friend. Their familiarity with the flow and usage of the menu indicated good internal and external consistency.

While some users made use of the suggested locations for the meetings, some preferred to specify their own locations, and were unsure of whether the system would support their actions, indicating a lack of affordance, and confusing the user.

Users found the instructions on the menu useful in accomplishing their tasks, though they did spend time reading it. We suspect that expert users will not experience the same lack of efficiency. Some were unsure about the behavior that would occur in order to propose a change to the event location, but were assured when they found the word "Propose" used. The "Revert Change" button being greyed out confused some users, and one user commented that changing it to "Undo" might be clearer, indicating a slight lack in external consistency, because we were not speaking the user's language.
