little period of relaxation. This means that the speed becomes slower for a short peri-
od of time and the player can catch their breath.
At the beginning, the application should use only simple gestures, introducing the
more complicated and tricky ones by the game's session duration.
A scoring system depends on several factors. First of all, a gesture game may re-
ward the player for the fast reaction. The less time it takes them to make a right ges-
ture, the more points they get. Zero seconds (which is practically impossible) gives
maximum score; the time which is equal to the interval gives the minimum number
of points or even gives a zero.
Then the player gets points for the accuracy. For each correct node of the gesture,
they get some points wherein they can receive the points on a linear base. In other
words, each node gives the same number of points or there can be a geometrical
progression accuracy rating. In the latter case, the player gets a lot of points by in-
putting the correct gesture. This is a good motivation to play attentively.
The optional way is to introduce special bonuses with some extra points. For ex-
ample, some gestures (complicated ones) can have a status that is gold, silver, plat-
inum, and so on. In the case of a fast and correct input, the player can be rewarded
with additional number of points. Special bonuses can also bring the player a small
supplement to the lifetime variable; this is useful for infinite game modes.
You can introduce an exclusive anti-mistake bonus, letting the player make some er-
rors in the game painlessly. It can become the most powerful bonus in the game, so
it must be hidden only in very intricate gestures.
Collecting gestures. Some basic gestures used in multitouch displays
The gestures are based on special control zones that the player touches. They work
separately as tap points or in combination forming a gesture sign. Let's imagine all
the gesture types the game can use:
