Last journal i mentioned a new plan about Joystick for our project. The users can use the joystick to response to the sound from different directions in the headphone. If i choose to develope this idea, i would make the joystick in a gun and fix it on the table, then use unity 3D to run the game,which is only about the audio. The headphone would tell the story about the game and simulate the sound of enemy attack from different directions. The users can just sit on chair and swing the gun to response to the attack. This concept could solve several problem we would meet in our previous plans, for example the safety issue and connecting issues. I even have come out the story for this method. “When zombies strike, people have to defend their homes. But the electricity was destroyed and people couldn't see the zombies at night. At this time, our blind hero stood up. Our hero has super hearing and can hear the location of the zombies, so he uses a gun to shoot against the zombies.”
I have done the Arduino stuffs, and clear about the functions about.I believe it can support out concept as well.In addition to controlling the four directions of up, down, left, and right, there is also a button in the middle which can be used to control the start/end of the game.
