Take in the whole. Before the parts.
Right Brain is a catalog of 30 short, beautiful perception minigames. Each one is a playful way to practise a single open skill: grasping a whole scene at a glance, before any one loud detail grabs your eye.
A scene flashes by for a brief, comfortable glance. You sense its gist — the average, the direction, the balance, the pattern. The whole, not the standout. One salient detail is built to pull your eye every round. Catching the whole anyway is the practice.
THIRTY WAYS TO PRACTISE
- Whole Before Parts — the big shape before the small ones
- At a Glance — the group's average size, not the standout
- Which Way — the overall lean of a field
- Common Fate — where the whole field flows
- Mirror — the balance of a whole figure
- Birds of a Feather — let likeness group the field
- Center of Gravity — where a whole cloud balances
- Crowd Feeling — the mood of a room, not one face
- True Colors, Follow the Line, How Many, Swirl, and more
ALWAYS SOMETHING NEW
- 30 distinct games, each a different way to read the whole
- Endless adaptive rounds, generated fresh, so they never repeat
- Difficulty tunes to your edge — within reach, never dull
- Choose your pace and session length: short, standard, or long
- Tap Surprise me for a random game
SCIENCE-FIRST, BY DESIGN
comun.ai builds Science-First. Every game maps to a peer-reviewed perception phenomenon — ensemble perception, Gestalt grouping, global motion, scene gist, biological motion, symmetry, closure, crowding, peripheral vision. Each carries an evidence grade: a real mix of Strong, Moderate, Early, and Contested. Where the science is still debated, we say so.
ABOUT THE NAME
You may have heard of "left brain" versus "right brain" personality types. Brain science has retired that idea — a large 2013 study (Nielsen et al.) found no such whole-brain type. So this is not hemisphere practice of any kind. The name is an evocative metaphor; the science is real, and we keep the two clearly apart.
NEVER A BRAIN SCORE
Watch your streaks, accuracy, and perception trend over time. An optional check-in shows how you feel before and after a session, in your own words. Concrete, self-reported signals — never a single invented number.
