Signal: Fundamental frequency of sound. Application: Raise the character with a high tone, lower it with a low tone. Access level: Signal analysis. <a id=\"variant-mic-017\"></a>\n- Tone buttons. Signal: Multiple relative ranges. Application: Select one of three elements in a low, medium or high tone. Access level: Signal analysis. <a id=\"variant-mic-018\"></a>\n- Holding a note. Signal: Close to target frequency. Application: Keep the beam on the target or keep the bridge open. Access level: Signal analysis. <a id=\"variant-mic-019\"></a>\n- Glissando. Alarm: Continuous rise or fall in altitude. Application: Use your voice to guide the platform along an inclined path. Access level: Signal analysis. <a id=\"variant-mic-020\"></a>\n- Melodic contour. Signal: A series of ups and downs. Application: Open the door with a motive that allows for a convenient tonality. Access level: Signal analysis. <a id=\"variant-mic-021\"></a>\n- Interval password. Signal: The relationship between successive tones. Application: Repeat the distances between notes regardless of the starting note. Access level: Signal analysis. <a id=\"variant-mic-022\"></a>\n- Accuracy of intonation. Signal: Deviation from specified notes. Application: Get points for hitting the melody. Access level: Signal analysis. <a id=\"variant-mic-023\"></a>\n- Vibrato and stability. Signal: Variation in altitude over time. Application: Vibrato modulates the shield; an even tone stabilizes the instrument. Access level: Signal analysis. <a id=\"variant-mic-024\"></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.
