Type: device. Fingers: Special equipment. Rule: The available hardware force value controls the parameter. Application: Mark thickness, grip force, tool volume. Only with real support; spare input via duration or slider. <a id=\"variant-t097\"></a>\n- Pressure threshold. Type: device. Fingers: Special equipment. Rule: The action is performed when the hardware force threshold is reached. Application: Push the material, turn on the second stage of the tool. A prolonged touch cannot be considered a force measurement. <a id=\"variant-t098\"></a>\n- Contact area. Type: device. Fingers: Special equipment. Rule: Estimating the size of the contact patch changes the properties of the brush or tool. Application: Wide sponge and thin brush. Data is noisy and device dependent; Do not use for precise finger identification. <a id=\"variant-t099\"></a>\n- Tilt of the stylus. Type: device. Fingers: Special equipment. Rule: The maintained angle of the active pen changes the shape of the action. Application: Side hatching, cutter angle, jet shape. <a id=\"variant-t100\"></a>\n- Rotate the stylus around its axis. Type: device. Fingers: Special equipment. Rule: If the pen imparts rotation, it specifies the orientation of the tool. Application: Rotate a flat brush, chisel, asymmetrical stamp. <a id=\"variant-t101\"></a>\n- Hover without touching. Type: device. Fingers: Special equipment. Rule: The compatible device reports the position of the pen above the screen. Application: Hit preview, aiming, preparing the next stroke. Do not consider it a normal feature of finger input. <a id=\"variant-t102\"></a>\n- Stylus button or eraser. Type: device. Fingers: Special equipment. Rule: Additional pen control selects action. Application: Temporarily turn on eraser, eyedropper, alternative tool. Depends on the pen and API. <a id=\"variant-t103\"></a>\n- Different roles of the pen and fingers. Type: device. Fingers: Special equipment. Rule: The type of pointer determines the purpose of the contact. Application: Write with a pen and move the canvas with your fingers, hold the template with your hand. You need a compatible phone and correct processing of random contacts. <a id=\"variant-t104\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
