2. “I´m not familiar with
the buildings i´m not
using”
“The hill is steeper than it
looks in maps”
“I would like to know
where there are other
spaces to study in buildings”
“People doesn´t know all
the food places around
campus”
“We stay in campus and
know where everything is,
but grad students may not
be connected”

7. Test scenario
“You are a grad student at Tufts and a
local Burger fan. Today you will be
meeting in campus two potential
investors for your research project
coming directly from Dubai. You are
expecting to talk in an informal
context, therefore you are searching
for the best place for local and
delicious burgers.”
Task 1: Find the best rated burger near campus
Task 3: Rate the place you visited
Task 2: Explore the “how to get there function”

“A search button could be useful, instead fo the
type of food menu”
“Show the filters after the type of food has
been selected”
“Could I get to the review
section in less clicks”

13. Using feedback
Move link to a more notorious spot

14. Using feedback
Filters should appear after the type of food selection
Adress a searching box
Search food:

15. Final ideas
Since automation is based largely in data storage and
retrieval, prototyping in keynote, made impossible to
address more reality to the navigation of the map.
Early testing is very helpful to assess the design, even due
to it´s limited functionality.
The view of the system designer about automation is very different
from the users perspective, this last one can experience a less degree
of freedom if everything is automated.
More manual control, increases input functionality over the interface,
which can confuse the user.
