Hand Controller mode uses a phone held in the hand - Do not equate one hand’s motion with precise full-body pose tracking. - [Just Dance Controller](https://apps.apple.com/us/app/just-dance-controller/id1634629424?uo=4) ## How it works A series of movements becomes a number, tempo, intensity or timing pattern. ## Variants ### Variants and applications - Shaking like a team. Action: A series of multidirectional oscillations is interpreted as one gesture. Application: Field reset, mixing, clearing an effect, calling an action. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Count the entire series, and not each half-wave as a separate command. - Accumulation from movement. Action: A measure of the intensity of movement over time fills a virtual resource. Application: Battery charge, warming up, spell energy, creature arousal. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: This is a conditional game resource, not a measurement of work or calories burned. - Counting complete cycles. Action: Completed pairs of phases of a repeating movement are counted. Application: Pump, swing, motor skills trainer, tasks for a certain number of repetitions. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Do not confuse the cycle with the number of peaks; set the minimum duration and range. - Maintaining the pace. Action: Repetition rate must remain within target range. Applications: Rowing, machine operation, combustion maintenance, rhythmic conveyor. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Requires several cycles for evaluation; the pace should be comfortable and adapt to the user. - Hitting the musical beat. Action: The impulse is evaluated relative to a given moment. Application: Rhythm game, virtual drum, synchronized action to music. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Rely on timestamps and take into account audio, sensor and feedback delays. - The right intensity. Action: Success is given for movement within the range, and not for the maximum. Application: Beating a mixture, calibrating a machine, caring for a fragile creature. Sensors: Name: Accelerometer; Value: Sufficient for the specified simplified scenario under the described conditions. Limitations: Show lower and upper bounds; compare a smoothed measure, not a single outlier. - Alternation of directions. Action: The order of movements along the axes or change of direction is checked. Application: Combination “left-right-up”, hacking, dance party, ritual. Sensors: Name: Accelerometer + gyroscope; Meaning: A bunch of sensors for orientation, rotation and separation of movement from gravity. Limitations: With A set a fixed grip; AG helps maintain sense of directions when rotating. - Rocking and changing rhythm. Action: Smooth periodic movement, acceleration or deceleration of the rhythm controls the process. Application: Rocking a character, rocking a swing, accelerating resonance, tempo spell. Sensors: Name: Accelerometer + gyroscope; Meaning: Bundle of sensors for orientation, rotation and separating movement from gravity. Limitations: Separate rotation from linear movement and match the game frequency with a convenient gesture. ## 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. ## Connected materials ## Sources and provenance Original editorial design catalog consolidated from project discussions on 2026-10-20.
