Obviously while the game needs to be simplistic enough to allow for a quick turn-around of participants, it also needs to be challenging enough so that any data gathered is valid. The game should include as many common gaming tasks as possible, such as, navigation, object selection and so on. I also wanted the game to have a fun, action, adventure, cartoon-like feel.
So with all this in mind, the concept for the game is as follows: the player is trapped in a rabbit warren, inhabited by evil bunny rabbits, from which they must escape. Players will be presented with a labyrinth of tunnels which they must find their way out of, collecting coins along the way, all the while avoid evil rabbits. Once the exit is found, players can only gain freedom (and win the game) depending on the number of coins collected. I have given it the working title "Rabbit Run".
The game is in first-person perspective, which, I think, lends itself well to gaze input. The above screen capture is taken from a demo I am working on at the moment. It shows the tunnels, the player must navigate through and one of the coins which must be collected along the way. Notice too the root in the tunnel, an obstacle which players must jump over. There will also be other roots higher up the tunnel wall, making players crouch to get past. Players will be given a map to guide them through the maze, which shows the areas of the maze traveled through. More on this in a later post, since there will be a subtle difference when using gaze interaction.
