Tilt gains a physical meaning: a ball rolls over a virtual surface. Labyrinth 2 adds walls, holes and other obstacles to the route.

1. The ball interacts with the virtual surface geometry

- Keep gravity direction, friction and input sensitivity consistent.

- [Labyrinth 2](https://apps.apple.com/us/app/labyrinth-2/id307758884?uo=4)

## How it works

Ready-made rules for virtual objects. Here tilt and acceleration acquire an objective meaning; These are derivative scenarios, not new types of sensors.

## Variants

### Variants and applications

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

- Gravity field control. Action: The direction of the tilt sets the virtual gravity acting on objects. Application: A ball in a maze, falling blocks, rolling of many objects. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Game gravity may have a convenient scale and limit that does not coincide with the real one. <a id="variant-m041"></a>
- Balance of mass and support. Action: Tilt redistributes the virtual load relative to the support. Application: Stack of objects, tower, bridge, balancing several loads. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Difference from a simple labyrinth lies in the center of mass, support and capsizing condition. <a id="variant-m042"></a>
- Transfusion of liquid. Action: The pose of the vessel and the time behind the angular threshold determine the virtual flow. Application: Pour the exact volume, do not spill, mix a drink, manage fuel. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Volume is calculated by simulation; The sensor does not measure the actual liquid in the phone. <a id="variant-m043"></a>
- Shaking and mixing. Action: Shaking changes the state of the virtual mixture. Application: Cocktail, paint, potion, foam, dissolving an ingredient. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Distinguish between the dose of movement, the order of the ingredients and the result of mixing. <a id="variant-m044"></a>
- Subsidence and delamination. Action: After shaking, you need to maintain rest or tilt. Application: Separate the sediment, develop layers, clean the sample, wait for crystallization. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: The alternation of activity and wait is important here; kinetics is the rule of simulation. <a id="variant-m045"></a>
- Sifting and sorting. Action: Tilt directs particles, shaking releases or passes them through barriers. Application: Sieve, sand, gold prospecting, sorting parts. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Dimensions, friction and passages are determined by the physical model; Intensity alone does not replace direction. <a id="variant-m046"></a>
- Waves, pendulums and elasticity. Action: Temporary motion pattern excites vibrations of a virtual object. Application: Water splash, jelly, spring, pendulum, suspension swing. Sensors: Name: Accelerometer + gyroscope; Meaning: A bunch of sensors for orientation, rotation and separation of motion from gravity. Limitations: To obtain controlled resonance, consider the phase, not just the magnitude of the acceleration. <a id="variant-m047"></a>
- Shake and release the simulation. Action: The gesture sets the initial impulses to the virtual bodies, after which they move on their own. Application: Bones, snow globe, particles, shuffled box. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Game randomness is set by a separate generator; Sensor noise does not promise an honest result. <a id="variant-m048"></a>

## Context and limits

96 mechanics and scenarios; Basic gestures, control schemes and derived applications are separated into layers. Examples are design ideas other than individually confirmed products.
