## How it works
A fast directed movement sets an impulse, throw or command, taking into account the speed and length of the gesture.
## Variants
### Variants and applications
- Directional swipe. Type: Touch. Fingers: 1. Rule: The direction of a sufficiently long movement selects the command. Application: Turn, change lane, dodge, choose the direction of the strike.
- Swipe length is like strength. Type: Touch. Fingers: 1. Rule: The amount of movement of the finger sets the power of the action. Application: Jump distance, step length, push force. This is a software scale, not a pressure measurement.
- Swipe speed is like power. Type: Touch. Fingers: 1. Rule: The force of action depends on the speed of movement of the finger. Application: Throwing a ball, hitting a club, launching a stone.
- Inertial throw. Type: Touch. Fingers: 1. Rule: After release, the object continues to move at the calculated speed. Application: Flick the puck, move the chip, spin the free list or game tape.
- Hit crossed targets. Type: Touch. Fingers: 1. Rule: One quick movement affects all crossed objects. Application: Chop flying targets, deflect several projectiles, carry out a sweeping attack.
- Pulling and releasing. Type: Touch. Fingers: 1. Rule: The displacement from the starting point sets the tension vector, releasing it launches the object. Application: Slingshot, bow, spring, catapult.
- Adding rotation. Type: Touch. Fingers: 1. Rule: Tangential movement is converted into angular impulse. Application: Spin the top, wheel, disk, give the ball a spin.
- Swipe as a solution. Type: Touch. Fingers: 1. Rule: Moving an object to one of the sectors selects the outcome. Application: Accept or reject an offer, arrange findings, select a dialogue option.
