Signal: Level threshold exceeded. Application: Use a clap or a short exclamation to launch a jump, shot, confirmation. Access level: Signal analysis. <a id=\"variant-mic-001\"></a>\n- Proportional control. Signal: Current signal level. Application: Use your voice to change speed, thrust, flight altitude or hand size. Access level: Signal analysis. <a id=\"variant-mic-002\"></a>\n- Multiple volume zones. Signal: Entering a quiet, medium or loud zone. Application: Choose between sneak, walk and run without recognizing words. Access level: Signal analysis. <a id=\"variant-mic-003\"></a>\n- Range hold. Signal: Time within a given level corridor. Application: Stabilize the reactor, preventing the sound from becoming too quiet or loud. Access level: Signal analysis. <a id=\"variant-mic-004\"></a>\n- Accumulation of sound energy. Signal: Level integral over the game window. Application: Gradually fill the spell scale; costs are determined by the game. Access level: Signal analysis. <a id=\"variant-mic-005\"></a>\n- Fade in and out. Signal: Direction and rate of level change. Application: Open the bridge with a smooth increase in sound, close the trap with attenuation. Access level: Signal analysis. <a id=\"variant-mic-006\"></a>\n- Peak control. Signal: Short exceeding of the comfortable threshold. Application: Handle with caution a creature that reacts to sharp sounds. Access level: Signal analysis. <a id=\"variant-mic-007\"></a>\n- Silence as action. Signal: Level below threshold when input is working. Application: Hide from a monster, stop a mechanism, maintain stealth. Access level: Signal analysis. <a id=\"variant-mic-008\"></a>"},{"id":"context","title":"Context and limits","body":"Author's design map for mobile games and interactive applications. 144 techniques in 18 groups, including basic signals, rules and combinations.
