Type: Touch. Fingers: 1+. Rule: The finger must remain within a small tolerance. Application: Balance the tool, stabilize the reactor, do not disturb the sleeping character. <a id=\"variant-t081\"></a>\n- Moving area tracking. Type: Touch. Fingers: 1+. Rule: You need to maintain contact with a moving target. Application: Hold a grip, follow a beam, guide a diagnostic sensor. <a id=\"variant-t082\"></a>\n- Forbidden areas. Type: Touch. Fingers: 1+. Rule: Touching certain areas violates the condition. Application: Labyrinth with electric walls, disarming a trap, precision operation. <a id=\"variant-t083\"></a>\n- Breakaway to evade. Type: Touch. Fingers: 1+. Rule: Lack of contact temporarily protects the object or disables its influence. Application: Remove a vulnerable marker finger, skip an obstacle, open a dangerous circuit. <a id=\"variant-t084\"></a>\n- Waiting without touching. Type: Touch. Fingers: 1+. Rule: Reward or progress appears only after a pause without input. Application: Calm the creature, wait for the image to appear, solve the patience puzzle. <a id=\"variant-t085\"></a>\n- Touch budget. Type: Touch. Fingers: 1+. Rule: The solution is given a limited number of contacts or the total holding time. Application: Minimize clicks, save device energy, solve a problem with one gesture. <a id=\"variant-t086\"></a>\n- Order of installation and removal. Type: multi. Fingers: 2+. Rule: Not only the positions are significant, but also the order in which contacts begin and end. Application: Open a multi-finger lock, remove the locks in a safe order. <a id=\"variant-t087\"></a>\n- Limit speed and smoothness. Type: Touch. Fingers: 1+. Rule: Too fast movements, stops or jerks violate the condition. Application: Carry explosives, guide a pen, perform fine assembly. <a id=\"variant-t088\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
