Action: A sequence, chord or pattern is first shown, then entered from memory. Applications: Memory play, procedure teaching, musical echo. Conditions: Pattern length, delay, and replay availability vary. Equipment: Regular keyboard. <a id=\"variant-k161\"></a>\n- Transform the pattern in your mind. Action: Enter the shown material in reverse order, with an offset or according to a conditional code. Application: Logic puzzle, melody transposition, encryption problem. Conditions: The transformation rule must be unambiguous. Equipment: A regular keyboard. <a id=\"variant-k162\"></a>\n- Find an unknown match. Action: Experiment with the keys and deduce a pattern based on the system's response. Application: Unknown panel, alien device, learning through exploration. Conditions: Sufficient feedback is needed for the solution to be deducible. Equipment: Regular keyboard. <a id=\"variant-k163\"></a>\n- React to the selected sign. Action: The command depends only on one of several properties of the tooltip. Application: Click on the color, ignoring the written word; sort dispatcher signals. Conditions: Feature conflict is a cognitive rule on top of a simple press. Equipment: Regular keyboard. <a id=\"variant-k164\"></a>\n- Switch rule. Action: The same stimulus requires different responses under the current condition. Application: Varying operator instructions, flexibility task, changing roles in training. Conditions: The current rule must be known or explicitly specified as a memory task. Equipment: Regular keyboard. <a id=\"variant-k165\"></a>\n- Combine two tasks. Action: Type text and simultaneously serve another thread of actions. Application: Correspondence while controlling the ship, music part plus alarms. Conditions: You can separately adjust the difficulty and tempo of each thread. Equipment: Regular keyboard. <a id=\"variant-k166\"></a>\n- Select a signal from interference. Action: Click only on significant events, ignoring similar false ones. Application: Radar operation, rhythmic track with distracting notes, searching for the necessary letters. Conditions: Distinguish between selection error, omission and time error. Equipment: Regular keyboard. <a id=\"variant-k167\"></a>\n- Master the scheme with decreasing hints. Action: Hints gradually disappear, but the location and rules are preserved. Application: Touch typing, teaching hot keys, mastering the musical layout. Conditions: The speed of removing hints should be based on the observed success of the user. Equipment: A regular keyboard. <a id=\"variant-k168\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
