## How it works
The value of a touch depends on the area of the screen, the state of the world, or the distribution of actions between participants.
## Variants
### Variants and applications
- Radial selection in one motion. Type: Touch. Fingers: 1+. Rule: Contact opens the menu, direction selects the sector, releasing confirms. Application: Quickly select a weapon, order, ingredient or replica.
- Preview and cancel. Type: Touch. Fingers: 1+. Rule: Holding shows the future result, withdrawing to the cancellation zone cancels the command. Application: Check the trajectory, choose a move safely, inspect the object before use.
- Magnifying glass or window under your finger. Type: Touch. Fingers: 1+. Rule: Contact position moves the area in which other data is visible. Application: Search for traces, read microtext, scan objects. Display important items offset from your finger.
- Sequential opening of the layer. Type: Touch. Fingers: 1+. Rule: Moving an edge or handle reveals a hidden part of the scene. Application: Flipping through a file, removing film, looking behind a curtain, matching layers of an image.
- The object is pushed away from the finger. Type: Touch. Fingers: 1+. Rule: Contact creates a field, obstacle or source of attraction. Application: Guide a flock, protect a passage, control fluid, push particles.
- Duel on one screen. Type: multi. Fingers: 2+. Rule: Players get different zones and independently create contacts. Application: Table football, reaction, fight for territory. For simultaneous play you need multi-touch.
- Joint holding of an object. Type: multi. Fingers: 2+. Rule: Success depends on the coordinated contacts of several participants. Application: Hold the two ends of the stretcher, simultaneously operate the valves, do not distort the platform.
- Counter Efforts. Type: multi. Fingers: 2+. Rule: The movements of two contacts turn into opposing play forces. Application: Tug of war, struggle for leverage, stretching of a common object. Powers are calculated from gestures...
