Type: multi. Fingers: 2+. Rule: Each active contact controls its own object. Application: Two characters, multiple traps, independent musical voices. <a id=\"variant-t073\"></a>\n- Movement and aiming. Type: multi. Fingers: 2+. Rule: Different input zones control movement and direction of action. Application: Two virtual sticks, movement plus vision or shooting. <a id=\"variant-t074\"></a>\n- Retention and separate team. Type: multi. Fingers: 2+. Rule: One finger supports the action, the other selects or activates the target. Application: Hold the shield and attack, hold the enemy and use the tool. <a id=\"variant-t075\"></a>\n- Modifier finger. Type: multi. Fingers: 2+. Rule: Contact in a special zone changes the meaning of the movement of the other finger. Application: Fine tuning, alternative tool, slow motion. <a id=\"variant-t076\"></a>\n- The section between the fingers. Type: multi. Fingers: 2+. Rule: Two contacts define a line that interacts with the world. Application: Membrane shield, laser barrier, trap, stretchable platform. <a id=\"variant-t077\"></a>\n- Polygon of contacts. Type: multi. Fingers: 2+. Rule: Three or more points define the area of ​​influence. Application: Capture creatures, hold a contour, cover several objects. Check contact limit and convenience. <a id=\"variant-t078\"></a>\n- Number of contacts. Type: multi. Fingers: 2+. Rule: The mode or command depends on the number of simultaneously active touches. Application: Choose the size of the instrument, the number of voices, the power of the ritual. The application does not recognize the identity of the finger. <a id=\"variant-t079\"></a>\n- Transferring a contact. Type: multi. Fingers: 2+. Rule: A new finger must enter before the previous one comes off, maintaining the general condition. Application: Carry energy along a chain, maintain a continuous bridge or cooperative grip. <a id=\"variant-t080\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
