Learning MS Office w/ Game Mechanics
"Games for learning is an increasingly popular field that’s quickly gaining ground. When we started this project, we wondered if there was a place for games in Office. We set out to understand whether elements of game play (things like scoring points, competing with friends, and earning achievements) could motivate people to explore more of the app, learn new features, and ultimately become more productive"

gDitty – Physical Activity Meter
gDitty makes moving around a fun, rewarding experience for kids. The gDitty product combines an activity meter with an online rewards program that motivates kids to move more. The gDitty device is worn on the belt or in a pocket. Activity data recorded by the gDitty is then uploaded to a kids’ personal profile on the gDitty website, where activity is calculated into points. These points can be redeemed for virtual goods and real-world rewards, including customizable avatars, gift cards, even the opportunity to make a donation to a cause.

Use Reinforcement Schedules
It's been shown that animals and humans work
to maximize a reward's frequency, not its
magnitude.
Put simply, "how often" is usually more important than
"how much." A mouse interacts more frequently with a reward schedule that rewards it more
frequently.

Use Reinforcement Schedules
Fixed interval (FI) schedules deliver reinforcement for the
first response after a fixed length of time since the last
reinforcement, while premature responses are not reinforced.
User gets points for
logging in to the site once
per day.
User gets points for watching
one video an hour.

Use Reinforcement Schedules
Variable interval (VI) schedules deliver reinforcement for the first response after a random average length of time passes since the last reinforcement.
User is rewarded with points for the first game
played after an average of 10 minutes from the last
game.

Use Reinforcement Schedules
Fixed Ratio (FR) schedules deliver
reinforcement after every nth response.
User gets a trophy after winning 50

User gets a reward

Use Reinforcement Schedules
Continuous ratio (CRF) schedules are a special form of
a fixed ratio. In a continuous ratio schedule, reinforcement
follows each and every response.
Every time a user posts to the forums
they earn points.

Reciprocity
Requires that one person try to repay what another
person has provided.
Future obligation benefits society, so everyone is
trained to obey this rule or face serious social
disapproval.

Reciprocity (2)
Applies even to uninvited first favors, which reduces our ability to decide whom we wish to owe.
Can spur unequal exchanges.
Can also take the form of initial concession that stimulates a return concession. Rejection then retreat.

Commitment & Consistency
After making a commitment, taking a stand, or position, people are more willing to agree to requests that are consistent with their prior
commitment.
• “I’ll watch your stuff”
• “I’ll get you that toy for Christmas”
• “I support the environment”
• “I’ll bet on that horse”
• “I’ll buy that car”

People often view a behavior as more correct in a given situation to the degree that we see
others performing it.

Scarcity
People assign more value to opportunities when they are less available.
• Things difficult to attain are typically more valuable. The availability of an item or experience can serve as a shortcut clue to its quality.
• When something becomes less accessible, the freedom to have it may be lost. People HATE to lose choices.

Scarcity (2)
Two optimizing conditions for scarcity:
• Scarce items are heightened in value when they are newly scarce. Things have higher value when they have become recently restricted – more than those things that were restricted all along.
• People are more attracted to scarce resources when they compete with others for them.
