Motivation

Currently people are often faced with the challenge of
having to live and work apart from family, friends
and colleagues.

Objective

Using “Airhockey over a distance” to support social
interactions and contribute to an increased
connectedness between people who are physically
apart.

Introduction


Social interaction is an essential human need.
We are interested in enabling social interactions
between friends and co-workers separated by distance.

How to improve social interaction? Casual games
We believe such games can work against the trend
of social decline if they support game-play between
participants that live geographically apart.

Method

Our approach focuses on two components:
─
─

High quality videoconference & physical game experience
Airhockey Over a Distance consists of two airhockey tables, half of
each is involved in game play and connected via a network.
Process
─
The player is recorded by a camera and the video is displayed on the
screen of the other player, creating the illusion of playing together on
one table.

Method (cont.)
─

How about the delay of an airhockey?
─
─

Once the puck passes the midway-line, it is detected, and a
corresponding physical puck is shot out at the other table.
The mechanical system, the network & videoconferencing
It’s tolerable for an enjoyable game experience after preliminary test
Other scenarios
─
─
─
─
Arcade
Airports
Youth clubs
Children’s hospitals

Preliminary findings


Approximately 30 people interacted with the system, and the
demonstration lasted for four hours.
The airhockey tables were set up in two different rooms, where
participants could neither see nor hear each other.

the speed and position of the pucks are randomly calculated.
Even though this was an informal evaluation, the
commend those participants give are not bed or
interesting.

Conclusions

Except casual game, the Airhockey Over a Distance
game is able to facilitate an increased connectedness
through social interaction between geographically
separated players.

Future work

We plan to improve the puck detection and firing system.
─
─

Puck detection : more accurate prediction will reduce the problem
resulting form the network latency.
Firing system : the spinning disk will limit the ability to quickly adjust
to fire pucks at a given speed.
After technically refining the system, our next step is to
formally analyze the affects of Airhockey Over a Distance on
players’ sense of connectedness to each other.
