Briefing

Thanks for agreeing to help us out!  What you see here is part of a project we’re working on for the User Interface Design class (6.813). Today, you’ll be helping us test a new system for keeping track of outsanding expenses among friends and acquaintances.  This system, called PennyPincher, is a means of recording and monitoring transactions among individuals and groups. We’re testing particular parts of the system which allows you to post new transactions to declare that someone owes you money, dispute a transaction you think is incorrect, and view a history of all transactions you’ve been a part of.

Here’s how it’s going to work: We're going to present you with a paper prototype of the mobile web app, which is fairly rough representation of what the mobile site might look after we build it, but on a much larger scale.  Depending on the type of mobile phone you are on, the stylus will be your mouse or your finger (for touchscreen phones).  We'll give you a few short tasks and ask you to try to execute them on this "web app". As you click on things, We’ll physically change the website to respond to your actions. Let me briefly introduce you to our team. My name is ___, and this is ____ and ___. After we get started I'll be controlling the "computer" and they're going to be taking notes to identify areas where we need to fix our system.
