We built three initial paper prototypes corresponding to the three designs we did in GR2 - Designs . We tested each of the prototypes on users and incorporated their feedback on our revised design.

Briefing
...
This is what we told the users:
"ShutterConnect is a service to help users find photographers for events like weddings and birthdays. We want to make it easy for you to find the right photographer for your location, event and budget.It is also a service that allows photographers to advertise to their services."
...
You are a photographer whose business is called "Awesome Shoots Inc." You want to describe yourself as a photographer primarily involved in portraiture and as who loves working with seniors. You have 3 sample photos to upload and you charge $500 per shoot by the hour. You live in Cambridge, near MIT.
Observations
Following are the comments that our final design received:
Our participants suggested that the 'sign up' field was so prominent that it was not clear that a user can search without signing in.
A positive criticism was that the help prompt in the search box was useful in hinting at the syntax to use while searching.
One participant took some time in deciding on how to move from the results of a photographer search to the photographer's page. The participant suggested that we add a button or a clearly afforded hyperlink on the photographer's name to this effect.
We plan on implementing a slider to facilitate selecting a user's budget. One participant suggested that we add a number to this slider, so that a user gets immediate feedback on what her selected budget constraint is.
It was also not clear how to conduct a new search while currently viewing results of a previous search. One participant suggested that clicking the logo to go back to the home page and start a new search was not obvious.
One participant suggested we change the search functionality such that entering a photographer's name and hitting enter immediately took the user to the photographer's profile page.
Instead of adding a visible status message whenever a user changes one of the parameters of a search, one test user suggested that we eliminate the status message altogether, and just use the checkbox on the left-most column of the search page to indicate that a parameter has changed.
We were also advised to add a popup with "Save/Cancel" buttons whenever a user clicked on an object to make it editable instead of just having the user assume that editing an element automatically saves it.
