12.1 The Concept
SB immediate liked the concept Mick had developed. 1 It was simple and involved
a small game where you had to 1) move physically and 2) solve math exercises.
The idea was to use a projector to project math exercises on the floor. The correct
answer to the question together with some incorrect ones were also displayed on the
floor. To spice it up a bit, the possible answers were presented on the back of small
creatures and the kid now has to step on the correct creature before it crawls out of
the scene and a new question is asked.
Mick showed a block-diagram, see Fig. 12.1 , to SB and explained the different
components of the system:
Game In this block, the math exercises are generated together with the possible an-
swers. The movements of the creatures are also controlled from this block. Lastly
it is decided whether the kid answers correctly by figuring out if one of his feet
touches the correct answer, an incorrect answer, or nothing.
Graphics This block generates the graphics.
Projector The physical projector, which projects the graphics.
Find feet This block takes input images from the camera and uses image processing
to find the position of the feet of the player.
Camera A camera filming the player.
“Damnation, you've been busy!” SB said, smiling at Mick.
“Well, that was the easy part, now comes the hard part,” SB replied seriously.
