  Consider implementing a bulk add, there are currently a lot of steps per friend request which will make adding a lot of people annoying.

  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.

  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”.

  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.

• 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.

• 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.

Action Icons/buttons on home page

Action icons were of the same color as action bar but in darker shade

Action icons are replaced by prominent and easy to locate buttons

Actions buttons are retained

Extra buttons on home page

Extra buttons did not have any functionality attached to them at that time.  

These buttons were removed.

in the "select location" page inside "create event" work flow now has a button on top right corner labeled "filter".
this button is used to modify the filters for location suggestions generated by application.

Search bar on home page

The search bar on home page is empty has a search button and a span button.

Search button is removed. the bar now performs incremental adaptive search.

Retained from the previous iteration design.

Default text inside Search Bars.

All the search bars had "Search" as their fragile default text.

There is Help text as fragile default texts in each search bar.

  Home Page Search bar says "Search for Friend by Name"

  Add a Friend search bar says "Search by Name or MIT Account ID"

  Select Location search bar says "Search by Building Number"

Default texts are retained from previous iteration design.

Confirmation dialog after adding a friend

a Dialogue box pops up when user adds a friend, asking whether they are sure or not. 

Confirmation message appears that friend is added and fades away in 10 seconds.   

Retained from the previous iteration design.

Adding a friend takes you back to ...?

Takes you back to home page.

Takes you back to search for a new friend page.

Takes you back to friend list.

Event page

Contains fields for data entry for: 

1. Title 
2. Start Time 
3. End Time 
4. Time Zone
5. Participants
6. Location

Simplified and now contains fewer data entry fields. 

1. Title 
2. Start Time 
3. Participants
4. Location

A new options is added, to specify if the event is closed or not. 
invitees can add more participants if event is not "closed event" and the "+" button against participants in RSVP page is enabled.  

Setting time of event

Time was automatically inserted, and could be changed using the numeric keypad

Ticker was introduced.
End time is omitted.

Ticker is retained, but now it has a button "done" which when pressed will hide the ticker.
Start time is by default set to one hour later, and has the affordance of a click/tap, and when tap will bring up the ticker. 

Time zone in Create Event page.

For consistency with other smart phone application "Time zone" field was there in "Create Event" page. It was by default set the user's current time zone and is un-editable.

Time zone field is dropped

Time zone field is dropped

Setting location while creating event.

Location can be typed or selected on map

Location can only be selected on map showing all the invited friends

Location selection retained from previous design. 
Filter can be set by user to tune the suggestions made by application. A button labeled "Filter" is displayed on the "Select Location" page. This button bring out a pop up with list of filter criteria and a hide button. this pop up is popped out by default for better visibility/learnability.




this detail will go on the "Prototype Photos" sections. 
 The "Location" field in "Create Event" page is affordance for click/tap, and when tapped it takes user to a map. Map shows

1. Location of friends selected as participants. 
2. Three Pins drops from the top on 3 suggested locations on map. 
3. A "Filter" pop up opened up on the right side which enlists important considerations user might have while selecting a place for meeting. user can check the check boxes against it and tap the hide button on top right of the pop up. By default the first option "near all the participants" is selected. 
   When user taps on a building, a list of meeting spaces available in that building will show up, sorted by the count of filter criteria each place meets, with icons against each place showing which selection criteria it meets. 
   user can click "other" to type in a location name which will then be added in the list.  
   
   tapping an item in list will bring user back to map view and a Confirmation Dialogue will show up at the bottom of the page. with name of location on it.
