Pendulum

Move with the beat of time — sustained focus and rhythm

In final preparation Included in CognitionVR
In a clockmaker's warm workshop the patient keeps time on a brass drum: syncing with the beat, answering at the swing's peak, staying vigilant for the clock that strikes 'wrong'.
Pendulum

Gameplay

In the clockmaker's wooden workshop, great brass pendulums swing slowly and gears turn in silence. Standing at the workbench, the patient keeps time with a brass drum: sometimes striking on every beat, sometimes answering exactly at the pendulum's peak, sometimes rebuilding a heard time interval from memory — and sometimes, in the calmest and hardest mission, just staying vigilant for the moment one of the clocks strikes “wrong”.

A sense of time and the power to “stay in the moment” underpin many skills. This exercise builds both: rhythm synchronization (with a recognized place in Parkinson's rehabilitation), temporal anticipation instead of late reaction, and attention endurance through monotony. Feedback is deliberately subtle so the patient's rhythm never breaks; a small continuous indicator shows “too early or too late”.

Motor complement

Rhythmic striking is upper-limb motor work in itself; the two-drum mode (left–right alternating) trains bimanual coordination and movement symmetry.

Therapeutic purpose

Pendulum targets sustained attention and vigilance — the capacity that wears out in driving and long tasks — together with rhythm and movement timing.

  • Parkinson's — rhythmic movement training
  • Adult attention disorders and attention fatigue after brain injury
  • Unstable movement timing and older adults

Clinician guide

The design is final and the exercise is queued for production. Once released, the tempo, mission type (sync/peak/interval rebuild/vigilance) and each segment's length are configured in the Level Designer.

  • Follow the news section for the release announcement.

Recorded metrics

  • Timing stability (how even are the strikes?)
  • Bias toward striking early or late
  • Attention lapses and focus decline from start to finish

علم و شواهد

Pendulum targets sustained attention and vigilance — the capacity that wears out in driving and long tasks — together with rhythm and movement timing.

Scientific basis

The "vigilance decrement" on long, monotonous tasks has been known since Mackworth's Clock Test (1948); the SART measures everyday attentional lapses by requiring response withholding on a rare target (Robertson et al., 1997). Sensorimotor synchronisation to a beat is a studied field in itself, and in Parkinson's, Rhythmic Auditory Stimulation has a recognised therapeutic role (Thaut et al., 1996).

Use in the cognitive treatment pathway

Parkinson's (rhythmic movement training), attention fatigue after brain injury and unstable timing in ageing are targets. Timing stability, an early/late bias and the decline of attention from start to finish are the key markers.

VR & digital evidence

Meta-analyses of Rhythmic Auditory Stimulation trials in Parkinson's show improved gait and motor scores (review by Nombela et al., 2013; meta-analysis by Zhang et al., 2022).

This exercise is a rehabilitation aid, not a substitute for clinical assessment or therapy; program selection and interpretation of results remain with the care team.
