Progress Thus Far Pilot Testing - Completed three pilot tests o Pilot #1 - Fiel and Viet o Pilot #2 - Fiel and Viet o Pilot #3 - Amir and Sabel o Final Pilots - Scheduled for Friday, May 7th Scheduling o sent out to 15 participants Usability Testing Phase o 13 participants have been scheduled for usability testing. (Presentation Updated - May 12, 2010) o 7 out of the 13 participants have been tested. (Presentation Updated - May 12, 2010)

Pilot #1 Problems Encountered: o "Pinch to zoom" feature o Android didn't pick up touch gestures ~10% of the time o Maintaining fluidity of script and speaking Insights Gained: o Practice makes perfect o Effective type of paper prototyping o iPhone users tend to assume all touch phones implement same gestures

Pilot #2 Problems Encountered: o Occasionally the UI is unresponsive, this confuses the user. o Users try the double click gesture often. o Timing of tasks sometimes skewed because users are trying to play with non-active features of the prototype. Insights Gained: o Moving a little quicker keeps attention. o Need to let user figure out the tasks without interfering but encouragement is good to avoid frustration

Pilot #3 Problems Encountered: o User found hidden button o Incomplete functions on prototype o Keeping track of activity time Insights Gained: o User learned functionality after repetitive questioning about the app's functions  Friend Bar example o Importance of Reinforcement--repetitive explanations  Frequent Friends

Scheduling Scheduling tells participant that we would like to schedule a time for him/her to come in to participate in the first phase of the software study of Longitude.
