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. <a id=\"variant-t033\"></a>\n- 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. <a id=\"variant-t034\"></a>\n- 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. <a id=\"variant-t035\"></a>\n- 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. <a id=\"variant-t036\"></a>\n- 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. <a id=\"variant-t037\"></a>\n- 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. <a id=\"variant-t038\"></a>\n- 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. <a id=\"variant-t039\"></a>\n- 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. <a id=\"variant-t040\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
