example of a 'mobile' game using RFID technology.
Knowledge Hunter is a simple idea for a 'mobile'
game that involves answering a question (usually related to the
current location) to get directions to the next
in the game, until all locations have been visited. A unique RFID
tag is placed at each of the locations. This 'triggers' the portable
a certain question when it comes into close proximity with the
The Knowledge Hunter application is written in Macromedia
data for the questions and locations is loaded into the game
using a separate XML file. This file can
altered, or a completely different XML file created with the Editor,
to cater for example to different age groups, quiz subjects,
or RFID tag locations, depending on the situation. This makes
Knowledge Hunter very quick and easy to customize and can turn
it into a versatile 'learning tool', as well as simply a 'fun'
in use - the answer to a question is found within a book
which contains a 'tag'
or altering a set of questions with the 'Editor' is quick and
In the example below, when a location is reached
and the tag found, a question related to the location has to be
answered correctly in order to get the directions to the next
location. A multiple choice format is used, with higher scores
gained for choosing the correct answer first. A 'skip' button allows
the question to be 'skipped', if for example the tag cannot be
found. The locations can be set to be visited in either a random
or sequential order
depending on the type of quiz required.
There are two test XML files you can use in the
example below; quiz.xml displays the questions in a random order
and quiz1.xml displays
the questions in sequence.
Note: In this
example you will have to click a small square button, 'L',
to simulate reaching a location. This does not of course appear
on the 'full' game.
