Augmented Reality ...in education
Simulations by the MIT Education Arcade & HGSE’s HARP Project

Handheld GamesAUGMENTED REALITYComputer simulation on handheld computers triggered by real world locations
• Goal - understand “authentic” science through simulated realistic practices
• Combines physical & virtual world contexts• Embeds learners in authentic situations• Engages users in a socially facilitated context
Handheld GamesAUGMENTED REALITYComputer simulation on handheld computers triggered by real world locations
A location-based experience• Uses GPS (Global Positioning
System) outdoors…• …or wi-fi positioning indoors
As participants move, their Pocket PCs knows their real location and provides location-specific information.
More about AR...Helmets v. Handhelds• Light augmentation
• Providing a small amount of “augmented” information. The environment and real people are integral and “real”.
• Heavy augmentation• The environment is used as a physical way
of navigating through virtual space. Environment can represent anything.
Environmental Detectives
• Players briefed about rash of local health problems linked to the environment
• Provided with background information and “budget”
• Determine source of pollution by drilling sampling wells and remediating with pumping wells
• Work in teams representing different interests (EPA, Industry, etc.)
Outdoor AR Advances• Features
• Structured around role dependent collaboration• Transcribed interview text, images or rich-media
(e.g., video) provide interview information.• Gates allow participants in outdoor simulations to
enter real buildings.
‘Evidence’ Screen• Use ‘Send Evidence Over IR’ to
prepare to make an accusation.• If a player has enough evidence,
he or she can interview a suspect to accuse them of a crime.
• A virtual character will only confess to a player who has all of the key evidence.
• To accuse a virtual character, simply interview them with enough evidence.
Examples of Customized Scenarios• Public Health - Charles River City
• Investigate mysterious health problems in Boston two weeks before the World Series
• Forensics - Mad City Murder• Investigate the death of a local resident and determine
whether it was murderMad City MurderCharles River City
Moving Indoors
• Indoor game played at the Boston Museum of Science
• Used 802.11 for positioning• Defining roles to enhance
collaboration• Introducing an element of
time to make it feel more like a game
• Solving a mystery using scientific information from the museum
Location InformationClick on items in the room to select them for viewing or picking up
Click on people in the room to select them for interviewing or showing objects to
To show an item that you already have to a Virtual Character, click on the person, then click Show and then choose the item that you want to show.
All screens tell you what room you’re currently in
To view an item in the room, click on the item and then click the View button.
To pick up an item in the room, click on the item and then click the Pick Up button.
To interview a virtual character click on the person and then click Interview

Collecting Virtual Samples
Using Contextual Information
“Participatory Reality”• Combining the features of AR and Participatory
Simulations to replicate authentic dynamic scientific practices where underlying models matter.• Participants are connected• Events unfold based on models• Game progresses differently each time

Outbreak @ MIT• You are actually an agent
in the system and can get sick or help the problem get under control
• Client-server based allows “one world” with underlying models and more realistic feel
• Evaluated by Public Health graduate students
One World
There’s a mask in this room. I need to protect myself, so I’ll pick it up.
One World
Since I picked it up, the mask has disappeared from the room. Other players no longer see it.
One World
The mask appears in my items list
One World
I’ll put it on myself

One World
Now it appears in my active items list, since I’m wearing it.
Outbreak @ MIT: Scenario• The Department of Public Health has been
investigating a recent flight from Chicago to Boston. Several passengers have become ill with a respiratory disease which may be SARS and are being housed in a Boston medical facility.
• Have two passengers associated with MIT contracted or spread the disease?• Cindy Hsiao, a visiting student• Quint Grandville, an MIT employee
Outbreak @ MIT: Game Design• Locations
Virtual characters and items are spread around MIT buildings
• Time30 mins of real time = 1 wk game time
• Disease transmission• Probability of infection depends on the amount of time you spend in a room with an
infected player or NPC.• Infection causes your “antigen level” to increase and your health level to drop.• Multiple disease models are built into the game.
• Multiple Rolesè
