1. The central target helps correct device tilt

- Set orientation tolerance and hold duration with sensor noise in mind.

## How it works

The user controls the quality of movement: holds, stabilizes, drives smoothly or freezes in time.

## Variants

### Variants and applications

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

- Fading. Action: Low variability of signals over a window of time is considered to fulfill the condition. Application: “Freeze”, stealth, waiting, stopping a dangerous mechanism. Sensors: Name: Accelerometer + gyroscope; Meaning: A bunch of sensors for orientation, rotation and separation of movement from gravity. Limitations: Low sensor activity does not prove absolute rest: uniform movement is not visible; A gyroscope is needed for rotation. <a id="variant-m033"></a>
- Sight with reassurance. Action: The more stable the orientation, the higher the accuracy or the faster the scale fills. Application: Sniper shot, photography, scanning, beam hold. Sensors: Name: Accelerometer + gyroscope; Meaning: A bunch of sensors for orientation, rotation, and separating motion from gravity. Limitations: This is a gaming stability assessment; Don't promise it will improve the real camera... <a id="variant-m034"></a>
- Horizontal balance. Action: The phone must be held close to the selected plane. Application: Tray, balancing platform, level, fragile load. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Select tolerance and allow convenient calibration; when moving the body, AG is better. <a id="variant-m035"></a>
- Uncomfortable preset position. Action: Target orientation is different from the usual neutral. Application: Tightrope walker's balance, holding a key in a lock, position puzzle. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Do not require extreme positions of the hand; increase the accuracy of the rule, not the amplitude of the gesture. <a id="variant-m036"></a>
- Following a moving target. Action: The player smoothly guides the orientation of the phone following the target angle. Application: Wiring an antenna, catching the wind, repeating a gesture, kinetic music. Sensors: Name: Accelerometer + gyroscope; Meaning: Bundle of sensors for orientation, rotation and separation of motion from gravity. Limitations: Compare angle and time to tolerance; do not turn the filter delay into a penalty. <a id="variant-m037"></a>
- Compensation for disturbances. Action: The game changes the virtual balance, and the user responds with a counter tilt. Application: Storm, shaky bridge, load on a platform, balancing robot. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Disturbances are generated by the simulation; the sensor does not measure the forces acting on the virtual load. <a id="variant-m038"></a>
- Careful carrying. Action: The task limits sudden movements and unwanted tilt at the same time. Application: Carry a virtual cup, bomb, sleeping animal, unstable sample. Sensors: Name: Accelerometer + gyroscope; Meaning: Bundle of sensors for orientation, rotation and separation of motion from gravity. Limitations: Test relative smoothness and orientation; The carrying distance is not known separately. <a id="variant-m039"></a>
- Stop on signal. Action: Before the signal, movement is allowed, after it you need to quickly reduce activity. Application: “Red light”, musical statues, reaction to danger, stop mechanism. Sensors: Name: Accelerometer + gyroscope; Meaning: Bundle of sensors for orientation, rotation and separation of motion from gravity. Limitations: Provide a response window and evaluate residual motion; A single zero count is not enough. <a id="variant-m040"></a>
