Action: The angle directly specifies the position of the object; returning the phone returns the object. Application: Arkanoid racket, slider, platform position, cursor. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Suitable for a limited range; you need a neutral posture and a small dead zone... <a id=\"variant-m001\"></a>\n- Incline → speed. Action: The stronger the tilt, the faster the object moves; in neutral it stops. Application: Platformer character, sliding through menus, scrolling long text. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Limit maximum speed; give me the opportunity to stop quickly... <a id=\"variant-m002\"></a>\n- Tilt → acceleration. Action: Tilt adds acceleration; the accumulated virtual speed is preserved. Application: Ship with inertia, physics puzzle, movement on a slippery surface. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: This is a game object model, not a measured phone speed; braking needs to be explained. <a id=\"variant-m003\"></a>\n- Tilt in two axes. Action: The two tilt components set the direction on the plane, and the deviation from the neutral sets the input amount. Application: 2D joystick, moving around the map, controlling the drone in a conventional plane. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Convert axes to screen orientation and select circular or split dead zone. <a id=\"variant-m004\"></a>\n- Rudder, roll and pitch. Action: The angle of the phone controls the rotation of the vehicle or the deviation of the virtual body. Application: Auto racing, airplane, snowboard, boat, glider. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: For quiet slopes, A is sufficient; for fast rotations, a combination with a gyroscope is preferable. <a id=\"variant-m005\"></a>\n- Fine adjustment of the sight. Action: Small changes in orientation move the sight relative to its original position. Application: Shooting after rough finger pointing, sniper optics, presentation pointer. Sensors: Name: Accelerometer + gyroscope; Meaning: A bunch of sensors for orientation, rotation and separation of movement from gravity. Limitations: For horizontal rotation and fast adjustment, a gyroscope is needed; provide for re-centering. <a id=\"variant-m006\"></a>\n- Tilt → parameter. Action: One axis changes the value, two axes control two related parameters. Application: Volume and timbre, scale, wind force, launch angle and power, color mixing. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: State the limits and current value; decide whether it persists after returning to neutral. <a id=\"variant-m007\"></a>\n- Slope → state mixing. Action: Deviation smoothly changes the proportion of two states or the degree of disclosure of the effect. Application: The world of light and shadow, manifestation of a hidden layer, card transparency, transition between forms. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Keep the range small to keep the screen readable. <a id=\"variant-m008\"></a>"},{"id":"context","title":"Context and limits","body":"96 mechanics and scenarios; Basic gestures, control schemes and derived applications are separated into layers.
