Overview

All the users looked at the home screen for a long time to figure out how
to find the overview. They did not realize that the photo was clickable.
One user explored the map because that user thought that it indicated
the overview information of users that were able to see that user’s
location. This user then tried visiting the friends page and asked if the
user had to navigate to all friends pages to determine who all could see
this user in a particular location. Once at the profile page (after being guided
there), they were able to spot the “LocaShares Overview” button and knew
what that meant.

Found the overview pages easy to use. One user discovered a system error
when that user found a few locashare names that weren’t states listed in
the “States” tab. There was another system error when a user tried navigating
to the home screen from the overview pages using the home icon in the header.

 

 

 

Reflection:

Different group of users have different mindsets in using an application. How to make the app has high usability to all users is a hard problem. Therefore, how to make the app easy to learn and easy to understand becomes important since it is nearly impossible to make an app cater to all the people.
* It is hard to hide system implementation from design. Programmers are used to “programming language” and sometimes this makes the app not speak user’s “human language.” For example, we used to have “latitude, longitude” to express user’s current location.
* The tradeoff between implementation and design. Good designs might sometimes entail hard implementations. In this course, we don’t have many chances to do prototyping on implementations, therefore, even though we had some really nice design features in paper-prototying, we were unable to carry it out due to implementation limitation. This also makes us deviate from our previous design and produces immature features.
