Type: multi. Fingers: 2+. Rule: The distance between the contacts controls the scale. Application: Change the scale of the map or the size of the game object. <a id=\"variant-t065\"></a>\n- Rotate with two fingers. Type: multi. Fingers: 2+. Rule: The angle between the contacts controls the rotation. Application: Orient a piece, rotate a puzzle, combine constellations. <a id=\"variant-t066\"></a>\n- Two finger transfer. Type: multi. Fingers: 2+. Rule: The general displacement of the contacts transfers the object or space. Application: Move the map, camera, large structure separately from the game selection. <a id=\"variant-t067\"></a>\n- Anchor and lever. Type: multi. Fingers: 2+. Rule: One contact fixes the support, the other controls the position relative to it. Application: Work with a compass, rotate the lever, pull the rope around the support. <a id=\"variant-t068\"></a>\n- Stretching. Type: multi. Fingers: 2+. Rule: Individual contacts move different points of a deformable object. Application: To stretch dough, rubber, membrane or bridge. <a id=\"variant-t069\"></a>\n- Shift layers. Type: multi. Fingers: 2+. Rule: The relative movement of the contacts changes the shift or misalignment of the parts. Application: Align transparent plates, loosen the connection, deform the mesh. <a id=\"variant-t070\"></a>\n- Conditional compression. Type: multi. Fingers: 2+. Rule: Bringing fingers together is interpreted programmatically as squeezing. Application: Squeeze out a sponge, compress a spring, crush a soft object. The screen does not measure actual grip force. <a id=\"variant-t071\"></a>\n- Bend at control points. Type: multi. Fingers: 2+. Rule: The position of several contacts determines the angle or curvature of the model. Application: Fold paper, bend wire, open a virtual book. <a id=\"variant-t072\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
