Paper Prototyping
Prototype Photos
Select photos from our prototyping session are included here. We have pictures of each stage of our application in addition to before and after pictures between our iterations. We also recorded video of all of our sessions, but did not include those here to preserve the privacy of our testers.

Briefing
EatTogether is a website designed to allow people to order food for delivery from food trucks at MIT. In a minute, we are going to ask you to carry out a couple of ordering tasks. However, first we would like to ask you a couple of background questions:
- What do you usually do for lunch?
- Have you eaten at the food trucks?
- If so, which ones? Which is your favorite?
- How often do you eat with friends?
- Do you eat with your research group? If so, how often?
- Do you ever skip lunch? If so, why?
- Do you order food online? (CampusFood, GubHub)
Scenario Tasks
Task 1:
You are at the Media Lab and you decided to order the following from clover: 1 BLT Sandwich.

Observations - Round 1
User 1
This user eats from the food trucks but prefers eating at Stata for lunch. The Asian Bistro truck is his favorite lunch truck. The user usually eats lunch with friends but not his research group which is made up of 3-4 people. Sometimes however, the user skips lunch because of conflicting meetings. Ordering online for dinner is a usual activity that the user does.
...
Overall, the user thought the interface was pretty intuitive, but has to ask for help to complete Task 2. When the user had to delete one the dishes in the cart, he pressed the wrong button, the x corresponding to the quantify (for example “1 x Coffee”) instead of the x for the deletion button. Also, after going back to the menu and realizing that there is no entree cheaper than $5, the user did not know what to do. He was then assisted by the facilitator to see whether there are other trucks. From there, the user was able to complete the task. He mentioned in the end that he would’ve clicked on the upper arrows, but assumed it’s not clickable because its not red.

Observations - Round 2
User 4
For lunch, this user either buys food from the Asian truck or places around Kendall square. The user usually eats lunch with friends. A couple of times a week however, the user skips or delays lunch because of either waking up late or classes. The user has tried ordering lunch and dinner online from CampusFood.
...
User 6
Overall, the user did some back and forth steps to accomplished the tasks, especially Task 2. In the task, the user had to delete the item added to add a cheaper one. The user had to go forth and back to check the amount of the item to make sure the new one selected is cheaper. For deleting the item, the user was confused as to whether he should press the “edit order” or the x button to remove the item.
Take aways and ideas for improvements
Overall, users found the general interface simple, intuitive and easy to use. The main difficulties the users faced had to do with the impoverished affordance of the paper prototype.
