In-Depth Information
By the way, the radar can be turned into a general element of the gameplay; a game
can hide something in a random position within the sphere of events. The element
is very tiny so it cannot be easily noticed from a distance, but the radar can hint at
its location by changing the tone of its sonar sound or using special animation. That
can be an improvised adventure game.
Remember that for an AR game to be perceived as a reliable product should be very
observant and honest. If the system notices any trouble with the AR environment, for
instance, the fiducial is lost or it is too dark, it must pause the game and display an
alert so a player knows the current conditions are bad and should be adjusted. The
interruption of the game process in the case of technical difficulties is necessary; oth-
erwise, it can be very frustrating. The game scene disappears from the screen, but
events continue somewhere within the application, causing a loss of game progress.
The image-recognition algorithms can report some problems with the light. Addition-
ally, it may track a fiducial and pause the game if a very sharp and dramatic change
of values occurs, signaling that the marker is lost. Hence, it is good to have a special
support system in a game to avoid misunderstandings with players.
