1. Brush Pressure Slider enables a software pressure control

- Contact area is not force; check the specific phone and stylus.

## How it works

Device-supported pressure, contact geometry, and stylus parameters complement the coordinates; capabilities are checked separately.

## Variants

### Variants and applications

<a id="family-13-variants"></a>

- Pressure force. 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>
- 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>
- 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>
- 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>
- 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>
- 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>
- 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>
- 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>

## Context and limits

Author's working classification for designing games and interactions. Options can overlap and combine; the list is not a generally accepted standard or proven exhaustive list. Application examples are conditional unless a specific verifiable observation is indicated nearby. Sources support individual techniques and technical limitations.
