Hello,
my name is Apostolis Ampatzoglou and i am a PhD student from Greece. At the
moment i am investigating the factors that make a game interesting to the user.
Please find attached a form that describes the factors under study and fill it
in accoerding to one of your games technical characteristics. In case you
participate in the survey your game will be hand out to 100 hundrend testers
for evaluation (of course the results will be at your disposal at any time). In
case of the paper being publicated there will be a refernce to your game's web
page!
Thank in advance,
Apostolis Ampatzoglou

The Networking attribute describes if the virtual world is multiplayer (NW=10),
single-user network world (meaning that two
users can run the application via the web, but cannot interact or see each
other NW=5), or local (NW=1). Additionally, the
Number of Input Devices Signal describes the number of signals the world
receives and uses from input devices. For example,
if the only input device is the mouse, the value of the NIDS attribute will be
4 (x-position, y-position, left click, right
click). Furthermore, the Number of Events attribute describes the number of
events that can be triggered by any user action.
Moreover, the Number of User Character Animations presents the number of
possible animations the user character can execute.
For example, if a character can sit on a chair, stand up from it and walk, then
the value of NUCA is 3. Finally, the Paths
of Movement attribute describes if the user can move only on predefined paths
(PM=1) or move without limits in two (PM=3) or
three dimensions (PM=10).
Firstly, the World Rules attribute, presents the number of rules that govern
the virtual world. These rules describe the
results of user actions and change world objects states. For example a rule
that suggests that an actor who is having a
key can open a locked door by clicking on it, could be written as Door(Locked)
AND Door->OnClick() AND Actor(hasKey) =>
Door (Unlocked). Additionally, the World States attribute, presents the number
of world objects states that the user can
interact with. In the example given above, three world states appear, the
Door(Locked), the Door(Unlocked) and the
Actor(hasKey), so WS=3. Furthermore, the User Properties variable presents the
number of attributes that the user has.
These attributes differentiate the worlds behavior in various executions of
world rules. For example, lets return to the
Javelin game example, if the throw of the athlete is correlated to his height,
his muscles and his technique that are
represented by three integers in the database of the system, then UP=3.
Finally, the Computer Character Properties presents
the sum of number of attributes of computer characters. These attributes
differentiate the worlds behavior in various
executions of world rules. The differences from the UP attribute is that if the
database, in the aforementioned example, has
six (6) competitors, then CP=18 (6x3).
Firstly, the Number of Polygons attribute presents the average number of
polygons employed to depict any graphical object.
Additionally, the Point of View attribute describes the projection type
(Orthographic [PV+0] or Perspective [PV+2]), the
camera types (Fixed [PV+0], Free or Target [PV+1], both [PV+2]) and the camera
movement freedom (Stable [PV+0], move in 1D
[PV+1], move in 2D [PV+2] or move in 3D [PV+3]). Furthermore, the Environment
attribute describes the collision detection
algorithm (No Collision Detection [ENV+0], Sphere-Cube Algorithm [ENV+2] or
Advanced Algorithm [ENV+3]), the special (No
Shading [ENV+0], Shading Enabled [ENV+2], No Fog [ENV+0], Fog [ENV+2]) and
lighting effects involved in the game (No Lights
[ENV+0], Min Lights Calculations [ENV+1], Complete Light Calculations or
Lightmaps [ENV+3]). Moreover, the Coloring
attribute describes the coloring of objects, by taking into account the balance
between textures and materials, special
coloring techniques as multitexturing, bump mapping and number of pixels in the
images used as textures (Only materials
[CLR+0], Only Textures [CLR+2], Combination of Texture and Materials [CLR+3],
Bump Mapping [CLR+5], Multitexturing [CLR+7],
the output is calculated as the fraction of objects that employ each technique
multiplied with the techniques rating.)
Additionally, the average number of textures pixels is multiplied with 10 and
added to the previous sum. Finally, the
Frames per Animation attribute and the Frames per Second attribute are employed
in order to evaluate the realism of movement
by presenting the average number of frames in actor animations and by
presenting the frames per second that a typical
computer can achieve in rendering the scenes of the world.
