The circuit should be able to control a computer game designed by us which requires only 4 distinct input commands.
The team has to select one speaker amongst themselves, who will give the voice commands to the microphone of the circuit.
The game is designed such that it tests the processing speed and accuracy of the circuit.
The circuit will be connected to CPU with the help of a parallel port connector whose specifications are given below.
The game is a modified version of Pac-Man with the ghosts removed.
Each player begins at the corner of the maze.
Each team is given 2 minutes to earn points. Points will be earned by eating the dots. Getting energizers and fruits will earn extra points. The exact point system will be disclosed soon.
An output of 00 on the wires represents the direction 'down' for the Pac-Man.
An output of 01 on the wires represents the direction 'right' for the Pac-Man.
An output of 10 on the wires represents the direction 'left' for the Pac-Man.
An output of 11 on the wires represents the direction 'up' for the Pac-Man.
The words to be used as input from the microphone are:
Up , down, left and right
One , two , three and four
East , west , north and south.
Participants can choose any of the sets out of these. These commands should be used to get the desired output. The participants should not use the length and the general loudness of the spoken words to recognize the words but actually differentiate between the words on the basis of characteristics like the frequency spectrum etc.
Note: Once a command is given, the output of the two wires must remain in the same state (example 01 or 10) until the next command is given.
