Signal: Class “bell”, “clap”, “bark”. Usage: Trigger a game event when the selected sound appears. Access level: Recognition. <a id=\"variant-mic-081\"></a>\n- Sound search for objects. Signal: Confirmed sound categories. Application: Collect a collection: find the rustle of paper, the clink of metal, splashing. Access level: Recognition. <a id=\"variant-mic-082\"></a>\n- Animal recognition. Signal: Similarity to classes of animal voices. Application: Keep a sound diary or search for a suitable virtual companion. Access level: Recognition. <a id=\"variant-mic-083\"></a>\n- Impact material. Signal: Timbre response under controlled conditions. Application: Compare wood, metal and glass in an exploration puzzle. Access level: Recognition. <a id=\"variant-mic-084\"></a>\n- Condition of the mechanism. Signal: Deviation from recorded game patterns. Application: Based on the sound of the educational model, look for which mechanism works differently. Access level: Recognition. <a id=\"variant-mic-085\"></a>\n- Sequence of events. Signal: Class order and temporal connections. Application: Read the recipe for “knock, ringing, rustling” or restore a short scene. Access level: Recognition. <a id=\"variant-mic-086\"></a>\n- Your own sound mark. Signal: Similarity to the sample recorded by the player. Application: Assign any convenient home sound to a game command. Access level: Recognition. <a id=\"variant-mic-087\"></a>\n- Unusual sound. Signal: Deviation from the learned background. Application: Play a watchman or researcher reacting to new events. Access level: Recognition. <a id=\"variant-mic-088\"></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.
