Art Walking: High Level Design (HLD) Document
1. Introduction
In the Louvre in Paris, there is an art expedition showing for a limited time. The wing
gallery in which it is being held, however, has a very limited amount of space. In this
program, an organization is set up to host the most amount of people and the most
amount of art in that crowded space while keeping the guests comfortable and
happy.

3. Requirements
Look at the story in the introduction and answer the following questions:
○ What are the characters in the story (the nouns)? These are the agents in the
model.
-Curator
-Gallery
-Art
-People/Guests
○ Do any of the characters have adjectives describing them? These are the
depictions of the agent. Which agents have multiple depictions and what are
they?
-Curator: 1x1 square
-Gallery: Has a right entrance and a left exit. 20x40 square
-Art: Three pieces at the start. Each 1x1 square. Multiple depictions…
 Beginning art
 Newly Added Art
-Guests: 1x1 square. Multiple depictions…
 Neutral
 Happy
 Unhappy
Each time step=30 seconds
○ What activities does each character do? These are behaviors of the agent.
-Curator: Counts the number of unhappy and happy people. Adds new pieces
of artwork to gallery.
-Guests: Will walk around the gallery viewing artwork. Will leave satisfied or
frustrated. Each guest enters with a given number (crowd tolerance) and a
color (category of art they are drawn to).
-Art: Gallery begins with just three art pieces. More are added progressively.
Each piece is framed with a color.
○ When do the activities take place? Does anything have to be true for the
activity to take place?
-The happiness/comfort of the guests depends on the amount of people
inside the gallery at the same time as them.
-No more artwork will be added to the gallery if the guests’ unhappiness
reaches eighty percent.
-It must be true that the guest has viewed fifty percent or more of the
artwork in order to happily exit the gallery.
-The guests’ length of stay is affected by their crowd tolerance exceeding.
○ How do the characters do each activity? Describe the behaviors in detail, step
by step.
-Curator: The Curator will count how many people leave happy and unhappy.
He will add a new piece of artwork to the gallery every twenty-five time steps
and will continue doing so until the model runs for two-hundred and fifty
time steps.
-Gallery: The gallery begins with three pieces of artwork being displayed.
Every twenty-four hours, a new piece will be placed within it.
-Art: The art begins inside the gallery and is progressively added. Each piece
of artwork is framed with different colors. Each color will draw certain guests
to certain art pieces.
-Guests: A random number of guests between zero and four enter the gallery
on the right side every time step. They can walk left, right, up, and down but
not diagonally and can only move one square at a time. When they enter, they
receive a number and a color. They walk around the gallery only drawn to
the art pieces framed with the color they received. To view an art piece, the
guests pause next to it for a random number of time steps between one and
five. Once the guest is satisfied with viewing only the artwork framed with
the color they are drawn to, they happily exit the gallery on the left side. In
addition to this, the guests have a “crowd tolerance” which will be a random
number between five and twenty-five given to them at the entrance as well. If
the number of people inside the gallery exceed the tolerance number of a
guest, the guest will exit the gallery unhappy. If there are too many unhappy
guests, the gallery will close down before finishing all its time steps.
OPTIONAL:
Coffee as a crowd tolerance/happiness increaser
The curator walks around the outside walls of the gallery with a tray of ten
coffee mugs. He continuously offers coffee to the guests who randomly pass
by and every time he passes by the entrance of the gallery, his coffee storage
restocks back to ten. The guests’ happiness percentage can be increased with
a cup of coffee. Coffee increases their crowd tolerance by seven percent.
Based on your answers to these questions, create an outline that describes the
agents in the story. For instance:
a. A [Javascript/Agentsheets] model showing the interactions of agents which
exhibit the following behaviors:
i. Curator
1. Counts the number of guests who leave happily or unhappily.
2. After twenty-five time steps, places a new art piece in the gallery.
ii. Guests
1. Walks in from the right. Can walk in any direction except
diagonal and only one square at a time.
2. Receives color and crowd tolerance.
3. Is drawn only to artwork framed in designated color.
4. Leaves unhappily if crowd tolerance is exceeded.
5. Leaves happily if sees all of artwork framed in designated
color.
iii. Art
1. Each artwork is framed with a color that never changes.
2. Color draws guests near them.
4. Timeline
This is due within five days of receipt of the task (that would be Friday, June 20 for
those receiving this Monday, June 16). It is better to complete this sooner, so that
you can begin implementing an HLD that one of your classmates has written.
5. Desired Behavior / Components
How would you model agent 1 doing behavior 1? Give a step by step explanation of
how each agent does each behavior. Think about how you will demonstrate the
behavior in the AgentSheets model.
Curator
a. Counts the number of happy and unhappy people.
b. Brings in new piece of artwork.
c. Counts the number of happy and unhappy people.
Guests
a. Enters through the right.
b. Receives color and number.
c. Walks towards artwork framed in designated color.
d. If number of people in the room exceeds crowd tolerance, leaves
through the left unhappily.
e. If sees all color framed artwork, leave through the left happily.
Replace the words in bold with your own words. Add more steps if you need them.
Do this for each behavior of each agent.
6. Conclusion
The goal in this activity is to learn how to manage a limitless amount of people in a
limited amount of space. This activity includes real sentiments of the people and
their comfort. Their happiness can increase or decrease and they have certain likes
and dislikes. Some people prefer less people in the room and others don’t mind. This
activity sheds light on all of those preferences to create an environment that is
comfortable and happy for everyone while learning how to organize the small space
within it.
